Question: 41 OF THE PERSONS IN REFERENCE TO THE NOTIONAL ACTS (SIX ARTICLES)

   We now consider the persons in reference to the notional acts, concerning which six points of inquiry arise:

    (1) Whether the notional acts are to be attributed to the persons?

    (2) Whether these acts are necessary, or voluntary?

    (3) Whether as regards these acts, a person proceeds from nothing or from something?

    (4) Whether in God there exists a power as regards the notional acts?

    (5) What this power means?

    (6) Whether several persons can be the term of one notional act?

Whether the notional acts are to be attributed to the persons?

  Objection 1: It would seem that the notional acts are not to be attributed to the persons. For Boethius says (De Trin.): "Whatever is predicated of God, of whatever genus it be, becomes the divine substance, except what pertains to the relation." But action is one of the ten "genera." Therefore any action attributed to God belongs to His essence, and not to a notion.

  Objection 2: Further, Augustine says (De Trin. v, 4,5) that, "everything which is said of God, is said of Him as regards either His substance, or relation." But whatever belongs to the substance is signified by the essential attributes; and whatever belongs to the relations, by the names of the persons, or by the names of the properties. Therefore, in addition to these, notional acts are not to be attributed to the persons.

  Objection 3: Further, the nature of action is of itself to cause passion. But we do not place passions in God. Therefore neither are notional acts to be placed in God.

  On the contrary, Augustine (Fulgentius, De Fide ad Petrum ii) says: "It is a property of the Father to beget the Son." Therefore notional acts are to be placed in God.

  I answer that, In the divine persons distinction is founded on origin. But origin can be properly designated only by certain acts. Wherefore, to signify the order of origin in the divine persons, we must attribute notional acts to the persons.

  Reply to Objection 1: Every origin is designated by an act. In God there is a twofold order of origin: one, inasmuch as the creature proceeds from Him, and this is common to the three persons; and so those actions which are attributed to God to designate the proceeding of creatures from Him, belong to His essence. Another order of origin in God regards the procession of person from person; wherefore the acts which designate the order of this origin are called notional; because the notions of the persons are the mutual relations of the persons, as is clear from what was above explained (Question [32], Article [2]).

  Reply to Objection 2: The notional acts differ from the relations of the persons only in their mode of signification; and in reality are altogether the same. Whence the Master says that "generation and nativity in other words are paternity and filiation" (Sent. i, D, xxvi). To see this, we must consider that the origin of one thing from another is firstly inferred from movement: for that anything be changed from its disposition by movement evidently arises from some cause. Hence action, in its primary sense, means origin of movement; for, as movement derived from another into a mobile object, is called "passion," so the origin of movement itself as beginning from another and terminating in what is moved, is called "action." Hence, if we take away movement, action implies nothing more than order of origin, in so far as action proceeds from some cause or principle to what is from that principle. Consequently, since in God no movement exists, the personal action of the one producing a person is only the habitude of the principle to the person who is from the principle; which habitudes are the relations, or the notions. Nevertheless we cannot speak of divine and intelligible things except after the manner of sensible things, whence we derive our knowledge, and wherein actions and passions, so far as these imply movement, differ from the relations which result from action and passion, and therefore it was necessary to signify the habitudes of the persons separately after the manner of act, and separately after the manner of relations. Thus it is evident that they are really the same, differing only in their mode of signification.

  Reply to Objection 3: Action, so far as it means origin of movement, naturally involves passion; but action in that sense is not attributed to God. Whence, passions are attributed to Him only from a grammatical standpoint, and in accordance with our manner of speaking, as we attribute "to beget" with the Father, and to the Son "to be begotten."

Article: 2

Whether the notional acts are voluntary?

  Objection 1: It would seem that the notional acts are voluntary. For Hilary says (De Synod.): "Not by natural necessity was the Father led to beget the Son."

  Objection 2: Further, the Apostle says, "He transferred us to the kingdom of the Son of His love" (Col. 1:13). But love belongs to the will. Therefore the Son was begotten of the Father by will.

  Objection 3: Further, nothing is more voluntary than love. But the Holy Ghost proceeds as Love from the Father and the Son. Therefore He proceeds voluntarily.

  Objection 4: Further, the Son proceeds by mode of the intellect, as the Word. But every word proceeds by the will from a speaker. Therefore the Son proceeds from the Father by will, and not by nature.

  Objection 5: Further, what is not voluntary is necessary. Therefore if the Father begot the Son, not by the will, it seems to follow that He begot Him by necessity; and this is against what Augustine says (Ad Orosium qu. vii).

  On the contrary, Augustine says, in the same book, that, "the Father begot the Son neither by will, nor by necessity."

  I answer that, When anything is said to be, or to be made by the will, this can be understood in two senses. In one sense, the ablative designates only concomitance, as I can say that I am a man by my will---that is, I will to be a man; and in this way it can be said that the Father begot the Son by will; as also He is God by will, because He wills to be God, and wills to beget the Son. In the other sense, the ablative imports the habitude of a principle as it is said that the workman works by his will, as the will is the principle of his work; and thus in that sense it must be said the God the Father begot the Son, not by His will; but that He produced the creature by His will. Whence in the book De Synod, it is said: "If anyone say that the Son was made by the Will of God, as a creature is said to be made, let him be anathema." The reason of this is that will and nature differ in their manner of causation, in such a way that nature is determined to one, while the will is not determined to one; and this because the effect is assimilated to the form of the agent, whereby the latter acts. Now it is manifest that of one thing there is only one natural form whereby it exists; and hence such as it is itself, such also is its work. But the form whereby the will acts is not only one, but many, according to the number of ideas understood. Hence the quality of the will's action does not depend on the quality of the agent, but on the agent's will and understanding. So the will is the principle of those things which may be this way or that way; whereas of those things which can be only in one way, the principle is nature. What, however, can exist in different ways is far from the divine nature, whereas it belongs to the nature of a created being; because God is of Himself necessary being, whereas a creature is made from nothing. Thus, the Arians, wishing to prove the Son to be a creature, said that the Father begot the Son by will, taking will in the sense of principle. But we, on the contrary, must assert that the Father begot the Son, not by will, but by nature. Wherefore Hilary says (De Synod.): "The will of God gave to all creatures their substance: but perfect birth gave the Son a nature derived from a substance impassible and unborn. All things created are such as God willed them to be; but the Son, born of God, subsists in the perfect likeness of God."

  Reply to Objection 1: This saying is directed against those who did not admit even the concomitance of the Father's will in the generation of the Son, for they said that the Father begot the Son in such a manner by nature that the will to beget was wanting; just as we ourselves suffer many things against our will from natural necessity---as, for instance, death, old age, and like ills. This appears from what precedes and from what follows as regards the words quoted, for thus we read: "Not against His will, nor as it were, forced, nor as if He were led by natural necessity did the Father beget the Son."

  Reply to Objection 2: The Apostle calls Christ the Son of the love of God, inasmuch as He is superabundantly loved by God; not, however, as if love were the principle of the Son's generation.

  Reply to Objection 3: The will, as a natural faculty, wills something naturally, as man's will naturally tends to happiness; and likewise God naturally wills and loves Himself; whereas in regard to things other than Himself, the will of God is in a way, undetermined in itself, as above explained (Question [19], Article [3]). Now, the Holy Ghost proceeds as Love, inasmuch as God loves Himself, and hence He proceeds naturally, although He proceeds by mode of will.

  Reply to Objection 4: Even as regards the intellectual conceptions of the mind, a return is made to those first principles which are naturally understood. But God naturally understands Himself, and thus the conception of the divine Word is natural.

  Reply to Objection 5: A thing is said to be necessary "of itself," and "by reason of another." Taken in the latter sense, it has a twofold meaning: firstly, as an efficient and compelling cause, and thus necessary means what is violent; secondly, it means a final cause, when a thing is said to be necessary as the means to an end, so far as without it the end could not be attained, or, at least, so well attained. In neither of these ways is the divine generation necessary; because God is not the means to an end, nor is He subject to compulsion. But a thing is said to be necessary "of itself" which cannot but be: in this sense it is necessary for God to be; and in the same sense it is necessary that the Father beget the Son.

Whether the notional acts proceed from something?

  Objection 1: It would seem that the notional acts do not proceed from anything. For if the Father begets the Son from something, this will be either from Himself or from something else. If from something else, since that whence a thing is generated exists in what is generated, it follows that something different from the Father exists in the Son, and this contradicts what is laid down by Hilary (De Trin. vii) that, "In them nothing diverse or different exists." If the Father begets the Son from Himself, since again that whence a thing is generated, if it be something permanent, receives as predicate the thing generated therefrom just as we say, "The man is white," since the man remains, when not from white he is made white---it follows that either the Father does not remain after the Son is begotten, or that the Father is the Son, which is false. Therefore the Father does not beget the Son from something, but from nothing.

  Objection 2: Further, that whence anything is generated is the principle regarding what is generated. So if the Father generate the Son from His own essence or nature, it follows that the essence or nature of the Father is the principle of the Son. But it is not a material principle, because in God nothing material exists; and therefore it is, as it were, an active principle, as the begetter is the principle of the one begotten. Thus it follows that the essence generates, which was disproved above (Question [39], Article [5]).

  Objection 3: Further, Augustine says (De Trin. vii, 6) that the three persons are not from the same essence; because the essence is not another thing from person. But the person of the Son is not another thing from the Father's essence. Therefore the Son is not from the Father's essence.

  Objection 4: Further, every creature is from nothing. But in Scripture the Son is called a creature; for it is said (Ecclus. 24:5), in the person of the Wisdom begotten,"I came out of the mouth of the Most High, the first-born before all creatures": and further on (Ecclus. 24:14) it is said as uttered by the same Wisdom, "From the beginning, and before the world was I created." Therefore the Son was not begotten from something, but from nothing. Likewise we can object concerning the Holy Ghost, by reason of what is said (Zach. 12:1): "Thus saith the Lord Who stretcheth forth the heavens, and layeth the foundations of the earth, and formeth the spirit of man within him"; and (Amos 4:13) according to another version [*The Septuagint]: "I Who form the earth, and create the spirit."

  On the contrary, Augustine (Fulgentius, De Fide ad Petrum i, 1) says: "God the Father, of His nature, without beginning, begot the Son equal to Himself."

  I answer that, The Son was not begotten from nothing, but from the Father's substance. For it was explained above (Question [27], Article [2]; Question [33], Articles [2],3) that paternity, filiation and nativity really and truly exist in God. Now, this is the difference between true "generation," whereby one proceeds from another as a son, and "making," that the maker makes something out of external matter, as a carpenter makes a bench out of wood, whereas a man begets a son from himself. Now, as a created workman makes a thing out of matter, so God makes things out of nothing, as will be shown later on (Question [45], Article [1]), not as if this nothing were a part of the substance of the thing made, but because the whole substance of a thing is produced by Him without anything else whatever presupposed. So, were the Son to proceed from the Father as out of nothing, then the Son would be to the Father what the thing made is to the maker, whereto, as is evident, the name of filiation would not apply except by a kind of similitude. Thus, if the Son of God proceeds from the Father out of nothing, He could not be properly and truly called the Son, whereas the contrary is stated (1 Jn. 5:20): "That we may be in His true Son Jesus Christ." Therefore the true Son of God is not from nothing; nor is He made, but begotten.

   That certain creatures made by God out of nothing are called sons of God is to be taken in a metaphorical sense, according to a certain likeness of assimilation to Him Who is the true Son. Whence, as He is the only true and natural Son of God, He is called the "only begotten," according to Jn. 1:18, "The only begotten Son, Who is in the bosom of the Father, He hath declared Him"; and so as others are entitled sons of adoption by their similitude to Him, He is called the "first begotten," according to Rm. 8:29: "Whom He foreknew He also predestinated to be made conformable to the image of His Son, that He might be the first born of many brethren." Therefore the Son of God is begotten of the substance of the Father, but not in the same way as man is born of man; for a part of the human substance in generation passes into the substance of the one begotten, whereas the divine nature cannot be parted; whence it necessarily follows that the Father in begetting the Son does not transmit any part of His nature, but communicates His whole nature to Him, the distinction only of origin remaining as explained above (Question [40], Article [2]).

  Reply to Objection 1: When we say that the Son was born of the Father, the preposition "of" designates a consubstantial generating principle, but not a material principle. For that which is produced from matter, is made by a change of form in that whence it is produced. But the divine essence is unchangeable, and is not susceptive of another form.

  Reply to Objection 2: When we say the Son is begotten of the essence of the Father, as the Master of the Sentences explains (Sent. i, D, v), this denotes the habitude of a kind of active principle, and as he expounds, "the Son is begotten of the essence of the Father"---that is, of the Father Who is essence; and so Augustine says (De Trin. xv, 13): "When I say of the Father Who is essence, it is the same as if I said more explicitly, of the essence of the Father."

   This, however, is not enough to explain the real meaning of the words. For we can say that the creature is from God Who is essence; but not that it is from the essence of God. So we may explain them otherwise, by observing that the preposition "of" [de] always denotes consubstantiality. We do not say that a house is "of" [de] the builder, since he is not the consubstantial cause. We can say, however, that something is "of" another, if this is its consubstantial principle, no matter in what way it is so, whether it be an active principle, as the son is said to be "of" the father, or a material principle, as a knife is "of" iron; or a formal principle, but in those things only in which the forms are subsisting, and not accidental to another, for we can say that an angel is "of" an intellectual nature. In this way, then, we say that the Son is begotten 'of' the essence of the Father, inasmuch as the essence of the Father, communicated by generation, subsists in the Son.

  Reply to Objection 3: When we say that the Son is begotten of the essence of the Father, a term is added which saves the distinction. But when we say that the three persons are 'of' the divine essence, there is nothing expressed to warrant the distinction signified by the preposition, so there is no parity of argument.

  Reply to Objection 4: When we say "Wisdom was created," this may be understood not of Wisdom which is the Son of God, but of created wisdom given by God to creatures: for it is said, "He created her [namely, Wisdom] in the Holy Ghost, and He poured her out over all His works" (Ecclus. 1:9,10). Nor is it inconsistent for Scripture in one text to speak of the Wisdom begotten and wisdom created, for wisdom created is a kind of participation of the uncreated Wisdom. The saying may also be referred to the created nature assumed by the Son, so that the sense be, "From the beginning and before the world was I made"---that is, I was foreseen as united to the creature. Or the mention of wisdom as both created and begotten insinuates into our minds the mode of the divine generation; for in generation what is generated receives the nature of the generator and this pertains to perfection; whereas in creation the Creator is not changed, but the creature does not receive the Creator's nature. Thus the Son is called both created and begotten, in order that from the idea of creation the immutability of the Father may be understood, and from generation the unity of nature in the Father and the Son. In this way Hilary expounds the sense of this text of Scripture (De Synod.). The other passages quoted do not refer to the Holy Ghost, but to the created spirit, sometimes called wind, sometimes air, sometimes the breath of man, sometimes also the soul, or any other invisible substance.

Whether in God there is a power in respect of the notional acts?

  Objection 1: It would seem that in God there is no power in respect of the notional acts. For every kind of power is either active or passive; neither of which can be here applied, there being in God nothing which we call passive power, as above explained (Question [25], Article [1]); nor can active power belong to one person as regards another, since the divine persons were not made, as stated above (Article [3]). Therefore in God there is no power in respect of the notional acts.

  Objection 2: Further, the object of power is what is possible. But the divine persons are not regarded as possible, but necessary. Therefore, as regards the notional acts, whereby the divine persons proceed, there cannot be power in God.

  Objection 3: Further, the Son proceeds as the word, which is the concept of the intellect; and the Holy Ghost proceeds as love, which belongs to the will. But in God power exists as regards effects, and not as regards intellect and will, as stated above (Question [25], Article [1]). Therefore, in God power does not exist in reference to the notional acts.

  On the contrary, Augustine says (Contra Maxim. iii, 1): "If God the Father could not beget a co-equal Son, where is the omnipotence of God the Father?" Power therefore exists in God regarding the notional acts.

  I answer that, As the notional acts exist in God, so must there be also a power in God regarding these acts; since power only means the principle of act. So, as we understand the Father to be principle of generation; and the Father and the Son to be the principle of spiration, we must attribute the power of generating to the Father, and the power of spiration to the Father and the Son; for the power of generation means that whereby the generator generates. Now every generator generates by something. Therefore in every generator we must suppose the power of generating, and in the spirator the power of spirating.

  Reply to Objection 1: As a person, according to notional acts, does not proceed as if made; so the power in God as regards the notional acts has no reference to a person as if made, but only as regards the person as proceeding.

  Reply to Objection 2: Possible, as opposed to what is necessary, is a consequence of a passive power, which does not exist in God. Hence, in God there is no such thing as possibility in this sense, but only in the sense of possible as contained in what is necessary; and in this latter sense it can be said that as it is possible for God to be, so also is it possible that the Son should be generated.

  Reply to Objection 3: Power signifies a principle: and a principle implies distinction from that of which it is the principle. Now we must observe a double distinction in things said of God: one is a real distinction, the other is a distinction of reason only. By a real distinction, God by His essence is distinct from those things of which He is the principle by creation: just as one person is distinct from the other of which He is principle by a notional act. But in God the distinction of action and agent is one of reason only, otherwise action would be an accident in God. And therefore with regard to those actions in respect of which certain things proceed which are distinct from God, either personally or essentially, we may ascribe power to God in its proper sense of principle. And as we ascribe to God the power of creating, so we may ascribe the power of begetting and of spirating. But "to understand" and "to will" are not such actions as to designate the procession of something distinct from God, either essentially or personally. Wherefore, with regard to these actions we cannot ascribe power to God in its proper sense, but only after our way of understanding and speaking: inasmuch as we designate by different terms the intellect and the act of understanding in God, whereas in God the act of understanding is His very essence which has no principle.
 
Article: 5

Whether the power of begetting signifies a relation, and not the essence?

  Objection 1: It would seem that the power of begetting, or of spirating, signifies the relation and not the essence. For power signifies a principle, as appears from its definition: for active power is the principle of action, as we find in Metaph. v, text 17. But in God principle in regard to Person is said notionally. Therefore, in God, power does not signify essence but relation.

  Objection 2: Further, in God, the power to act [posse] and 'to act' are not distinct. But in God, begetting signifies relation. Therefore, the same applies to the power of begetting.

  Objection 3: Further, terms signifying the essence in God, are common to the three persons. But the power of begetting is not common to the three persons, but proper to the Father. Therefore it does not signify the essence.

  On the contrary, As God has the power to beget the Son, so also He wills to beget Him. But the will to beget signifies the essence. Therefore, also, the power to beget.

  I answer that, Some have said that the power to beget signifies relation in God. But this is not possible. For in every agent, that is properly called power, by which the agent acts. Now, everything that produces something by its action, produces something like itself, as to the form by which it acts; just as man begotten is like his begetter in his human nature, in virtue of which the father has the power to beget a man. In every begetter, therefore, that is the power of begetting in which the begotten is like the begetter.

   Now the Son of God is like the Father, who begets Him, in the divine nature. Wherefore the divine nature in the Father is in Him the power of begetting. And so Hilary says (De Trin. v): "The birth of God cannot but contain that nature from which it proceeded; for He cannot subsist other than God, Who subsists from no other source than God."

   We must therefore conclude that the power of begetting signifies principally the divine essence as the Master says (Sent. i, D, vii), and not the relation only. Nor does it signify the essence as identified with the relation, so as to signify both equally. For although paternity is signified as the form of the Father, nevertheless it is a personal property, being in respect to the person of the Father, what the individual form is to the individual creature. Now the individual form in things created constitutes the person begetting, but is not that by which the begetter begets, otherwise Socrates would beget Socrates. So neither can paternity be understood as that by which the Father begets, but as constituting the person of the Father, otherwise the Father would beget the Father. But that by which the Father begets is the divine nature, in which the Son is like to Him. And in this sense Damascene says (De Fide Orth. i, 18) that generation is the "work of nature," not of nature generating, but of nature, as being that by which the generator generates. And therefore the power of begetting signifies the divine nature directly, but the relation indirectly.

  Reply to Objection 1: Power does not signify the relation itself of a principle, for thus it would be in the genus of relation; but it signifies that which is a principle; not, indeed, in the sense in which we call the agent a principle, but in the sense of being that by which the agent acts. Now the agent is distinct from that which it makes, and the generator from that which it generates: but that by which the generator generates is common to generated and generator, and so much more perfectly, as the generation is more perfect. Since, therefore, the divine generation is most perfect, that by which the Begetter begets, is common to Begotten and Begetter by a community of identity, and not only of species, as in things created. Therefore, from the fact that we say that the divine essence "is the principle by which the Begetter begets," it does not follow that the divine essence is distinct (from the Begotten): which would follow if we were to say that the divine essence begets.

  Reply to Objection 2: As in God, the power of begetting is the same as the act of begetting, so the divine essence is the same in reality as the act of begetting or paternity; although there is a distinction of reason.

  Reply to Objection 3: When I speak of the "power of begetting," power is signified directly, generation indirectly: just as if I were to say, the "essence of the Father." Wherefore in respect of the essence, which is signified, the power of begetting is common to the three persons: but in respect of the notion that is connoted, it is proper to the person of the Father.

Article: 6 

Whether several persons can be the term of one notional act?

  Objection 1: It would seem that a notional act can be directed to several Persons, so that there may be several Persons begotten or spirated in God. For whoever has the power of begetting can beget. But the Son has the power of begetting. Therefore He can beget. But He cannot beget Himself: therefore He can beget another son. Therefore there can be several Sons in God.

  Objection 2: Further, Augustine says (Contra Maxim. iii, 12): "The Son did not beget a Creator: not that He could not, but that it behoved Him not."

  Objection 3: Further, God the Father has greater power to beget than has a created father. But a man can beget several sons. Therefore God can also: the more so that the power of the Father is not diminished after begetting the Son.

  On the contrary, In God "that which is possible," and "that which is" do not differ. If, therefore, in God it were possible for there to be several Sons, there would be several Sons. And thus there would be more than three Persons in God; which is heretical.

  I answer that, As Athanasius says, in God there is only "one Father, one Son, one Holy Ghost." For this four reasons may be given.

   The first reason is in regard to the relations by which alone are the Persons distinct. For since the divine Persons are the relations themselves as subsistent, there would not be several Fathers, or several Sons in God, unless there were more than one paternity, or more than one filiation. And this, indeed, would not be possible except owing to a material distinction: since forms of one species are not multiplied except in respect of matter, which is not in God. Wherefore there can be but one subsistent filiation in God: just as there could be but one subsistent whiteness.

   The second reason is taken from the manner of the processions. For God understands and wills all things by one simple act. Wherefore there can be but one person proceeding after the manner of word, which person is the Son; and but one person proceeding after the manner of love, which person is the Holy Ghost.

   The third reason is taken from the manner in which the persons proceed. For the persons proceed naturally, as we have said (Article [2]), and nature is determined to one.

   The fourth reason is taken from the perfection of the divine persons. For this reason is the Son perfect, that the entire divine filiation is contained in Him, and that there is but one Son. The argument is similar in regard to the other persons.

  Reply to Objection 1: We can grant, without distinction, that the Son has the same power as the Father; but we cannot grant that the Son has the power "generandi" [of begetting] thus taking "generandi" as the gerund of the active verb, so that the sense would be that the Son has the "power to beget." Just as, although Father and Son have the same being, it does not follow that the Son is the Father, by reason of the notional term added. But if the word "generandi" [of being begotten] is taken as the gerundive of the passive verb, the power "generandi" is in the Son---that is, the power of being begotten. The same is to be said if it be taken as the gerundive of an impersonal verb, so that the sense be "the power of generation"---that is, a power by which it is generated by some person.

  Reply to Objection 2: Augustine does not mean to say by those words that the Son could beget a Son: but that if He did not, it was not because He could not, as we shall see later on (Question [42], Article [6], ad 3).

  Reply to Objection 3: Divine perfection and the total absence of matter in God require that there cannot be several Sons in God, as we have explained. Wherefore that there are not several Sons is not due to any lack of begetting power in the Father.

Question: 42 OF EQUALITY AND LIKENESS AMONG THE DIVINE PERSONS (SIX ARTICLES)

   We now have to consider the persons as compared to one another: firstly, with regard to equality and likeness; secondly, with regard to mission. Concerning the first there are six points of inquiry.

    (1) Whether there is equality among the divine persons?

    (2) Whether the person who proceeds is equal to the one from Whom He proceeds in eternity?

    (3) Whether there is any order among the divine persons?

    (4) Whether the divine persons are equal in greatness?

    (5) Whether the one divine person is in another?

    (6) Whether they are equal in power?
 
Article: 1 

Whether there is equality in God?

  Objection 1: It would seem that equality is not becoming to the divine persons. For equality is in relation to things which are one in quantity as the Philosopher says (Metaph. v, text 20). But in the divine persons there is no quantity, neither continuous intrinsic quantity, which we call size, nor continuous extrinsic quantity, which we call place and time. Nor can there be equality by reason of discrete quantity, because two persons are more than one. Therefore equality is not becoming to the divine persons.

  Objection 2: Further, the divine persons are of one essence, as we have said (Question [39], Article [2]). Now essence is signified by way of form. But agreement in form makes things to be alike, not to be equal. Therefore, we may speak of likeness in the divine persons, but not of equality.

  Objection 3: Further, things wherein there is to be found equality, are equal to one another, for equality is reciprocal. But the divine persons cannot be said to be equal to one another. For as Augustine says (De Trin. vi, 10): "If an image answers perfectly to that whereof it is the image, it may be said to be equal to it; but that which it represents cannot be said to be equal to the image." But the Son is the image of the Father; and so the Father is not equal to the Son. Therefore equality is not to be found among the divine persons.

  Objection 4: Further, equality is a relation. But no relation is common to the three persons; for the persons are distinct by reason of the relations. Therefore equality is not becoming to the divine persons.

  On the contrary, Athanasius says that "the three persons are co-eternal and co-equal to one another."

  I answer that, We must needs admit equality among the divine persons. For, according to the Philosopher (Metaph. x, text 15,16, 17), equality signifies the negation of greater or less. Now we cannot admit anything greater or less in the divine persons; for as Boethius says (De Trin. i): "They must needs admit a difference [namely, of Godhead] who speak of either increase or decrease, as the Arians do, who sunder the Trinity by distinguishing degrees as of numbers, thus involving a plurality." Now the reason of this is that unequal things cannot have the same quantity. But quantity, in God, is nothing else than His essence. Wherefore it follows, that if there were any inequality in the divine persons, they would not have the same essence; and thus the three persons would not be one God; which is impossible. We must therefore admit equality among the divine persons.

  Reply to Objection 1: Quantity is twofold. There is quantity of "bulk" or dimensive quantity, which is to be found only in corporeal things, and has, therefore, no place in God. There is also quantity of "virtue," which is measured according to the perfection of some nature or form: to this sort of quantity we allude when we speak of something as being more, or less, hot; forasmuch as it is more or less, perfect in heat. Now this virtual quantity is measured firstly by its source---that is, by the perfection of that form or nature: such is the greatness of spiritual things, just as we speak of great heat on account of its intensity and perfection. And so Augustine says (De Trin. vi, 18) that "in things which are great, but not in bulk, to be greater is to be better," for the more perfect a thing is the better it is. Secondly, virtual quantity is measured by the effects of the form. Now the first effect of form is being, for everything has being by reason of its form. The second effect is operation, for every agent acts through its form. Consequently virtual quantity is measured both in regard to being and in regard to action: in regard to being, forasmuch as things of a more perfect nature are of longer duration; and in regard to action, forasmuch as things of a more perfect nature are more powerful to act. And so as Augustine (Fulgentius, De Fide ad Petrum i) says: "We understand equality to be in the Father, Son and Holy Ghost, inasmuch as no one of them either precedes in eternity, or excels in greatness, or surpasses in power."

  Reply to Objection 2: Where we have equality in respect of virtual quantity, equality includes likeness and something besides, because it excludes excess. For whatever things have a common form may be said to be alike, even if they do not participate in that form equally, just as the air may be said to be like fire in heat; but they cannot be said to be equal if one participates in the form more perfectly than another. And because not only is the same nature in both Father and Son, but also is it in both in perfect equality, therefore we say not only that the Son is like to the Father, in order to exclude the error of Eunomius, but also that He is equal to the Father to exclude the error of Arius.

  Reply to Objection 3: Equality and likeness in God may be designated in two ways---namely, by nouns and by verbs. When designated by nouns, equality in the divine persons is mutual, and so is likeness; for the Son is equal and like to the Father, and conversely. This is because the divine essence is not more the Father's than the Son's. Wherefore, just as the Son has the greatness of the Father, and is therefore equal to the Father, so the Father has the greatness of the Son, and is therefore equal to the Son. But in reference to creatures, Dionysius says (Div. Nom. ix): "Equality and likeness are not mutual." For effects are said to be like their causes, inasmuch as they have the form of their causes; but not conversely, for the form is principally in the cause, and secondarily in the effect.

   But verbs signify equality with movement. And although movement is not in God, there is something that receives. Since, therefore, the Son receives from the Father, this, namely, that He is equal to the Father, and not conversely, for this reason we say that the Son is equalled to the Father, but not conversely.

  Reply to Objection 4: In the divine persons there is nothing for us to consider but the essence which they have in common and the relations in which they are distinct. Now equality implies both ---namely, distinction of persons, for nothing can be said to be equal to itself; and unity of essence, since for this reason are the persons equal to one another, that they are of the same greatness and essence. Now it is clear that the relation of a thing to itself is not a real relation. Nor, again, is one relation referred to another by a further relation: for when we say that paternity is opposed to filiation, opposition is not a relation mediating between paternity and filiation. For in both these cases relation would be multiplied indefinitely. Therefore equality and likeness in the divine persons is not a real relation distinct from the personal relations: but in its concept it includes both the relations which distinguish the persons, and the unity of essence. For this reason the Master says (Sent. i, D, xxxi) that in these "it is only the terms that are relative."

Whether the person proceeding is co-eternal with His principle, as the Son with the Father?

  Objection 1: It would seem that the person proceeding is not co-eternal with His principle, as the Son with the Father. For Arius gives twelve modes of generation. The first mode is like the issue of a line from a point; wherein is wanting equality of simplicity. The second is like the emission of rays from the sun; wherein is absent equality of nature. The third is like the mark or impression made by a seal; wherein is wanting consubstantiality and executive power. The fourth is the infusion of a good will from God; wherein also consubstantiality is wanting. The fifth is the emanation of an accident from its subject; but the accident has no subsistence. The sixth is the abstraction of a species from matter, as sense receives the species from the sensible object; wherein is wanting equality of spiritual simplicity. The seventh is the exciting of the will by knowledge, which excitation is merely temporal. The eighth is transformation, as an image is made of brass; which transformation is material. The ninth is motion from a mover; and here again we have effect and cause. The tenth is the taking of species from genera; but this mode has no place in God, for the Father is not predicated of the Son as the genus of a species. The eleventh is the realization of an idea [ideatio], as an external coffer arises from the one in the mind. The twelfth is birth, as a man is begotten of his father; which implies priority and posteriority of time. Thus it is clear that equality of nature or of time is absent in every mode whereby one thing is from another. So if the Son is from the Father, we must say that He is less than the Father, or later than the Father, or both.

  Objection 2: Further, everything that comes from another has a principle. But nothing eternal has a principle. Therefore the Son is not eternal; nor is the Holy Ghost.

  Objection 3: Further, everything which is corrupted ceases to be. Hence everything generated begins to be; for the end of generation is existence. But the Son is generated by the Father. Therefore He begins to exist, and is not co-eternal with the Father.

  Objection 4: Further, if the Son be begotten by the Father, either He is always being begotten, or there is some moment in which He is begotten. If He is always being begotten, since, during the process of generation, a thing must be imperfect, as appears in successive things, which are always in process of becoming, as time and motion, it follows that the Son must be always imperfect, which cannot be admitted. Thus there is a moment to be assigned for the begetting of the Son, and before that moment the Son did not exist.

  On the contrary, Athanasius declares that "all the three persons are co-eternal with each other."

  I answer that, We must say that the Son is co-eternal with the Father. In proof of which we must consider that for a thing which proceeds from a principle to be posterior to its principle may be due to two reasons: one on the part of the agent, and the other on the part of the action. On the part of the agent this happens differently as regards free agents and natural agents. In free agents, on account of the choice of time; for as a free agent can choose the form it gives to the effect, as stated above (Question [41], Article [2]), so it can choose the time in which to produce its effect. In natural agents, however, the same happens from the agent not having its perfection of natural power from the very first, but obtaining it after a certain time; as, for instance, a man is not able to generate from the very first. Considered on the part of action, anything derived from a principle cannot exist simultaneously with its principle when the action is successive. So, given that an agent, as soon as it exists, begins to act thus, the effect would not exist in the same instant, but in the instant of the action's termination. Now it is manifest, according to what has been said (Question [41], Article [2]), that the Father does not beget the Son by will, but by nature; and also that the Father's nature was perfect from eternity; and again that the action whereby the Father produces the Son is not successive, because thus the Son would be successively generated, and this generation would be material, and accompanied with movement; which is quite impossible. Therefore we conclude that the Son existed whensoever the Father existed and thus the Son is co-eternal with the Father, and likewise the Holy Ghost is co-eternal with both.

  Reply to Objection 1: As Augustine says (De Verbis Domini, Serm. 38), no mode of the procession of any creature perfectly represents the divine generation. Hence we need to gather a likeness of it from many of these modes, so that what is wanting in one may be somewhat supplied from another; and thus it is declared in the council of Ephesus: "Let Splendor tell thee that the co-eternal Son existed always with the Father; let the Word announce the impassibility of His birth; let the name Son insinuate His consubstantiality." Yet, above them all the procession of the word from the intellect represents it more exactly; the intellectual word not being posterior to its source except in an intellect passing from potentiality to act; and this cannot be said of God.

  Reply to Objection 2: Eternity excludes the principle of duration, but not the principle of origin.

  Reply to Objection 3: Every corruption is a change; and so all that corrupts begins not to exist and ceases to be. The divine generation, however, is not changed, as stated above (Question [27], Article [2]). Hence the Son is ever being begotten, and the Father is always begetting.

  Reply to Objection 4: In time there is something indivisible---namely, the instant; and there is something else which endures---namely, time. But in eternity the indivisible "now" stands ever still, as we have said above (Question [10], Article [2] ad 1, Article [4] ad 2). But the generation of the Son is not in the "now" of time, or in time, but in eternity. And so to express the presentiality and permanence of eternity, we can say that "He is ever being born," as Origen said (Hom. in Joan. i). But as Gregory [*Moral. xxix, 21] and Augustine [*Super Ps. 2:7] said, it is better to say "ever born," so that "ever" may denote the permanence of eternity, and "born" the perfection of the only Begotten. Thus, therefore, neither is the Son imperfect, nor "was there a time when He was not," as Arius said.
 
Article: 3 

Whether in the divine persons there exists an order of nature?

  Objection 1: It would seem that among the divine persons there does not exist an order of nature. For whatever exists in God is the essence, or a person, or a notion. But the order of nature does not signify the essence, nor any of the persons, or notions. Therefore there is no order of nature in God.

  Objection 2: Further, wherever order of nature exists, there one comes before another, at least, according to nature and intellect. But in the divine persons there exists neither priority nor posteriority, as declared by Athanasius. Therefore, in the divine persons there is no order of nature.

  Objection 3: Further, wherever order exists, distinction also exists. But there is no distinction in the divine nature. Therefore it is not subject to order; and order of nature does not exist in it.

  Objection 4: Further, the divine nature is the divine essence. But there is no order of essence in God. Therefore neither is there of nature.

  On the contrary, Where plurality exists without order, confusion exists. But in the divine persons there is no confusion, as Athanasius says. Therefore in God order exists.

  I answer that, Order always has reference to some principle. Wherefore since there are many kinds of principle---namely, according to site, as a point; according to intellect, as the principle of demonstration; and according to each individual cause---so are there many kinds of order. Now principle, according to origin, without priority, exists in God as we have stated (Question [33], Article [1]): so there must likewise be order according to origin, without priority; and this is called 'the order of nature': in the words of Augustine (Contra Maxim. iv): "Not whereby one is prior to another, but whereby one is from another."

  Reply to Objection 1: The order of nature signifies the notion of origin in general, not a special kind of origin.

  Reply to Objection 2: In things created, even when what is derived from a principle is co-equal in duration with its principle, the principle still comes first in the order of nature and reason, if formally considered as principle. If, however, we consider the relations of cause and effect, or of the principle and the thing proceeding therefrom, it is clear that the things so related are simultaneous in the order of nature and reason, inasmuch as the one enters the definition of the other. But in God the relations themselves are the persons subsisting in one nature. So, neither on the part of the nature, nor on the part the relations, can one person be prior to another, not even in the order of nature and reason.

  Reply to Objection 3: The order of nature means not the ordering of nature itself, but the existence of order in the divine Persons according to natural origin.

  Reply to Objection 4: Nature in a certain way implies the idea of a principle, but essence does not; and so the order of origin is more correctly called the order of nature than the order of essence.
 
Article: 4

Whether the Son is equal to the Father in greatness?

  Objection 1: It would seem that the Son is not equal to the Father in greatness. For He Himself said (Jn. 14:28): "The Father is greater than I"; and the Apostle says (1 Cor. 15:28): "The Son Himself shall be subject to Him that put all things under Him."

  Objection 2: Further, paternity is part of the Father's dignity. But paternity does not belong to the Son. Therefore the Son does not possess all the Father's dignity; and so He is not equal in greatness to the Father.

  Objection 3: Further, wherever there exist a whole and a part, many parts are more than one only, or than fewer parts; as three men are more than two, or than one. But in God a universal whole exists, and a part; for under relation or notion, several notions are included. Therefore, since in the Father there are three notions, while in the Son there are only two, the Son is evidently not equal to the Father.

  On the contrary, It is said (Phil. 2:6): "He thought it not robbery to be equal with God."

  I answer that, The Son is necessarily equal to the Father in greatness. For the greatness of God is nothing but the perfection of His nature. Now it belongs to the very nature of paternity and filiation that the Son by generation should attain to the possession of the perfection of the nature which is in the Father, in the same way as it is in the Father Himself. But since in men generation is a certain kind of transmutation of one proceeding from potentiality to act, it follows that a man is not equal at first to the father who begets him, but attains to equality by due growth, unless owing to a defect in the principle of generation it should happen otherwise. From what precedes (Question [27], Article [2]; Question [33], Articles [2],3), it is evident that in God there exist real true paternity and filiation. Nor can we say that the power of generation in the Father was defective, nor that the Son of God arrived at perfection in a successive manner and by change. Therefore we must say that the Son was eternally equal to the Father in greatness. Hence, Hilary says (De Synod. Can. 27): "Remove bodily weakness, remove the beginning of conception, remove pain and all human shortcomings, then every son, by reason of his natural nativity, is the father's equal, because he has a like nature."

  Reply to Objection 1: These words are to be understood of Christ's human nature, wherein He is less than the Father, and subject to Him; but in His divine nature He is equal to the Father. This is expressed by Athanasius, "Equal to the Father in His Godhead; less than the Father in humanity": and by Hilary (De Trin. ix): "By the fact of giving, the Father is greater; but He is not less to Whom the same being is given"; and (De Synod.): "The Son subjects Himself by His inborn piety"---that is, by His recognition of paternal authority; whereas "creatures are subject by their created weakness."

  Reply to Objection 2: Equality is measured by greatness. In God greatness signifies the perfection of nature, as above explained (Article [1], ad 1), and belongs to the essence. Thus equality and likeness in God have reference to the essence; nor can there be inequality or dissimilitude arising from the distinction of the relations. Wherefore Augustine says (Contra Maxim. iii, 13), "The question of origin is, Who is from whom? but the question of equality is, Of what kind, or how great, is he?" Therefore, paternity is the Father's dignity, as also the Father's essence: since dignity is something absolute, and pertains to the essence. As, therefore, the same essence, which in the Father is paternity, in the Son is filiation, so the same dignity which, in the Father is paternity, in the Son is filiation. It is thus true to say that the Son possesses whatever dignity the Father has; but we cannot argue---"the Father has paternity, therefore the Son has paternity," for there is a transition from substance to relation. For the Father and the Son have the same essence and dignity, which exist in the Father by the relation of giver, and in the Son by relation of receiver.

  Reply to Objection 3: In God relation is not a universal whole, although it is predicated of each of the relations; because all the relations are one in essence and being, which is irreconcilable with the idea of universal, the parts of which are distinguished in being. Persons likewise is not a universal term in God as we have seen above (Question [30], Article [4]). Wherefore all the relations together are not greater than only one; nor are all the persons something greater than only one; because the whole perfection of the divine nature exists in each person.
 
Article: 5

Whether the Son is in the Father, and conversely?

  Objection 1: It would seem that the Son and the Father are not in each other. For the Philosopher (Phys. iv, text. 23) gives eight modes of one thing existing in another, according to none of which is the Son in the Father, or conversely; as is patent to anyone who examines each mode. Therefore the Son and the Father are not in each other.

  Objection 2: Further, nothing that has come out from another is within. But the Son from eternity came out from the Father, according to Micheas 5:2: "His going forth is from the beginning, from the days of eternity." Therefore the Son is not in the Father.

  Objection 3: Further, one of two opposites cannot be in the other. But the Son and the Father are relatively opposed. Therefore one cannot be in the other.

  On the contrary, It is said (Jn. 14:10): "I am in the Father, and the Father is in Me."

  I answer that, There are three points of consideration as regards the Father and the Son; the essence, the relation and the origin; and according to each the Son and the Father are in each other. The Father is in the Son by His essence, forasmuch as the Father is His own essence and communicates His essence to the Son not by any change on His part. Hence it follows that as the Father's essence is in the Son, the Father Himself is in the Son; likewise, since the Son is His own essence, it follows that He Himself is in the Father in Whom is His essence. This is expressed by Hilary (De Trin. v), "The unchangeable God, so to speak, follows His own nature in begetting an unchangeable subsisting God. So we understand the nature of God to subsist in Him, for He is God in God." It is also manifest that as regards the relations, each of two relative opposites is in the concept of the other. Regarding origin also, it is clear that the procession of the intelligible word is not outside the intellect, inasmuch as it remains in the utterer of the word. What also is uttered by the word is therein contained. And the same applies to the Holy Ghost.

  Reply to Objection 1: What is contained in creatures does not sufficiently represent what exists in God; so according to none of the modes enumerated by the Philosopher, are the Son and the Father in each other. The mode the most nearly approaching to the reality is to be found in that whereby something exists in its originating principle, except that the unity of essence between the principle and that which proceeds therefrom is wanting in things created.

  Reply to Objection 2: The Son's going forth from the Father is by mode of the interior procession whereby the word emerges from the heart and remains therein. Hence this going forth in God is only by the distinction of the relations, not by any kind of essential separation.

  Reply to Objection 3: The Father and the Son are relatively opposed, but not essentially; while, as above explained, one relative opposite is in the other.

Article: 6 

Whether the Son is equal to the Father in power?

  Objection 1: It would seem that the Son is not equal to the Father in power. For it is said (Jn. 5:19): "The Son cannot do anything of Himself but what He seeth the Father doing." But the Father can act of Himself. Therefore the Father's power is greater than the Son's.

  Objection 2: Further, greater is the power of him who commands and teaches than of him who obeys and hears. But the Father commands the Son according to Jn. 14:31: "As the Father gave Me commandment so do I." The Father also teaches the Son: "The Father loveth the Son, and showeth Him all things that Himself doth" (Jn. 5:20). Also, the Son hears: "As I hear, so I judge" (Jn. 5:30). Therefore the Father has greater power than the Son.

  Objection 3: Further, it belongs to the Father's omnipotence to be able to beget a Son equal to Himself. For Augustine says (Contra Maxim. iii, 7), "Were He unable to beget one equal to Himself, where would be the omnipotence of God the Father?" But the Son cannot beget a Son, as proved above (Question [41], Article [6]). Therefore the Son cannot do all that belongs to the Father's omnipotence; and hence He is not equal to Him power.

  On the contrary, It is said (Jn. 5:19): "Whatsoever things the Father doth, these the Son also doth in like manner."

  I answer that, The Son is necessarily equal to the Father in power. Power of action is a consequence of perfection in nature. In creatures, for instance, we see that the more perfect the nature, the greater power is there for action. Now it was shown above (Article [4]) that the very notion of the divine paternity and filiation requires that the Son should be the Father's equal in greatness---that is, in perfection of nature. Hence it follows that the Son is equal to the Father in power; and the same applies to the Holy Ghost in relation to both.

  Reply to Objection 1: The words, "the Son cannot of Himself do anything," do not withdraw from the Son any power possessed by the Father, since it is immediately added, "Whatsoever things the Father doth, the Son doth in like manner"; but their meaning is to show that the Son derives His power from the Father, of Whom He receives His nature. Hence, Hilary says (De Trin. ix), "The unity of the divine nature implies that the Son so acts of Himself [per se], that He does not act by Himself [a se]."

  Reply to Objection 2: The Father's "showing" and the Son's "hearing" are to be taken in the sense that the Father communicates knowledge to the Son, as He communicates His essence. The command of the Father can be explained in the same sense, as giving Him from eternity knowledge and will to act, by begetting Him. Or, better still, this may be referred to Christ in His human nature.

  Reply to Objection 3: As the same essence is paternity in the Father, and filiation in the Son: so by the same power the Father begets, and the Son is begotten. Hence it is clear that the Son can do whatever the Father can do; yet it does not follow that the Son can beget; for to argue thus would imply transition from substance to relation, for generation signifies a divine relation. So the Son has the same omnipotence as the Father, but with another relation; the Father possessing power as "giving" signified when we say that He is able to beget; while the Son possesses the power of "receiving," signified by saying that He can be begotten.

Question: 43 THE MISSION OF THE DIVINE PERSONS (EIGHT ARTICLES)

   We next consider the mission of the divine persons, concerning which there are eight points of inquiry:

    (1) Whether it is suitable for a divine person to be sent?

    (2) Whether mission is eternal, or only temporal?

    (3) In what sense a divine person is invisibly sent?

    (4) Whether it is fitting that each person be sent?

    (5) Whether both the Son and the Holy Ghost are invisibly sent?

    (6) To whom the invisible mission is directed?

    (7) Of the visible mission

    (8) Whether any person sends Himself visibly or invisibly?
 
Article: 1 

Whether a divine person can be properly sent?

  Objection 1: It would seem that a divine person cannot be properly sent. For one who is sent is less than the sender. But one divine person is not less than another. Therefore one person is not sent by another.

  Objection 2: Further, what is sent is separated from the sender; hence Jerome says, commenting on Ezech. 16:53: "What is joined and tied in one body cannot be sent." But in the divine persons there is nothing that is separable, as Hilary says (De Trin. vii). Therefore one person is not sent by another.

  Objection 3: Further, whoever is sent, departs from one place and comes anew into another. But this does not apply to a divine person, Who is everywhere. Therefore it is not suitable for a divine person to be sent.

  On the contrary, It is said (Jn. 8:16): "I am not alone, but I and the Father that sent Me."

  I answer that, the notion of mission includes two things: the habitude of the one sent to the sender; and that of the one sent to the end whereto he is sent. Anyone being sent implies a certain kind of procession of the one sent from the sender: either according to command, as the master sends the servant; or according to counsel, as an adviser may be said to send the king to battle; or according to origin, as a tree sends forth its flowers. The habitude to the term to which he is sent is also shown, so that in some way he begins to be present there: either because in no way was he present before in the place whereto he is sent, or because he begins to be there in some way in which he was not there hitherto. Thus the mission of a divine person is a fitting thing, as meaning in one way the procession of origin from the sender, and as meaning a new way of existing in another; thus the Son is said to be sent by the Father into the world, inasmuch as He began to exist visibly in the world by taking our nature; whereas "He was" previously "in the world" (Jn. 1:1).

  Reply to Objection 1: Mission implies inferiority in the one sent, when it means procession from the sender as principle, by command or counsel; forasmuch as the one commanding is the greater, and the counsellor is the wiser. In God, however, it means only procession of origin, which is according to equality, as explained above (Question [42], Articles [4],6).

  Reply to Objection 2: What is so sent as to begin to exist where previously it did not exist, is locally moved by being sent; hence it is necessarily separated locally from the sender. This, however, has no place in the mission of a divine person; for the divine person sent neither begins to exist where he did not previously exist, nor ceases to exist where He was. Hence such a mission takes place without a separation, having only distinction of origin.

  Reply to Objection 3: This objection rests on the idea of mission according to local motion, which is not in God.
 
Article: 2

Whether mission is eternal, or only temporal?

  Objection 1: It would seem that mission can be eternal. For Gregory says (Hom. xxvi, in Ev.), "The Son is sent as He is begotten." But the Son's generation is eternal. Therefore mission is eternal.

  Objection 2: Further, a thing is changed if it becomes something temporally. But a divine person is not changed. Therefore the mission of a divine person is not temporal, but eternal.

  Objection 3: Further, mission implies procession. But the procession of the divine persons is eternal. Therefore mission is also eternal.

  On the contrary, It is said (Gal. 4:4): "When the fullness of the time was come, God sent His Son."

  I answer that, A certain difference is to be observed in all the words that express the origin of the divine persons. For some express only relation to the principle, as "procession" and "going forth." Others express the term of procession together with the relation to the principle. Of these some express the eternal term, as "generation" and "spiration"; for generation is the procession of the divine person into the divine nature, and passive spiration is the procession of the subsisting love. Others express the temporal term with the relation to the principle, as "mission" and "giving." For a thing is sent that it may be in something else, and is given that it may be possessed; but that a divine person be possessed by any creature, or exist in it in a new mode, is temporal.

   Hence "mission" and "giving" have only a temporal significance in God; but "generation" and "spiration" are exclusively eternal; whereas "procession" and "giving," in God, have both an eternal and a temporal signification: for the Son may proceed eternally as God; but temporally, by becoming man, according to His visible mission, or likewise by dwelling in man according to His invisible mission.

  Reply to Objection 1: Gregory speaks of the temporal generation of the Son, not from the Father, but from His mother; or it may be taken to mean that He could be sent because eternally begotten.

  Reply to Objection 2: That a divine person may newly exist in anyone, or be possessed by anyone in time, does not come from change of the divine person, but from change in the creature; as God Himself is called Lord temporally by change of the creature.

  Reply to Objection 3: Mission signifies not only procession from the principle, but also determines the temporal term of the procession. Hence mission is only temporal. Or we may say that it includes the eternal procession, with the addition of a temporal effect. For the relation of a divine person to His principle must be eternal. Hence the procession may be called a twin procession, eternal and temporal, not that there is a double relation to the principle, but a double term, temporal and eternal.
 
Article: 3 

Whether the invisible mission of the divine person is only according to the gift of sanctifying grace?

  Objection 1: It would seem that the invisible mission of the divine person is not only according to the gift of sanctifying grace. For the sending of a divine person means that He is given. Hence if the divine person is sent only according to the gift of sanctifying grace, the divine person Himself will not be given, but only His gifts; and this is the error of those who say that the Holy Ghost is not given, but that His gifts are given.

  Objection 2: Further, this preposition, "according to," denotes the habitude of some cause. But the divine person is the cause why the gift of sanctifying grace is possessed, and not conversely, according to Rm. 5:5, "the charity of God is poured forth in our hearts by the Holy Ghost, Who is given to us." Therefore it is improperly said that the divine person is sent according to the gift of sanctifying grace.

  Objection 3: Further, Augustine says (De Trin. iv, 20) that "the Son, when temporally perceived by the mind, is sent." But the Son is known not only by sanctifying grace, but also by gratuitous grace, as by faith and knowledge. Therefore the divine person is not sent only according to the gift of sanctifying grace.

  Objection 4: Further, Rabanus says that the Holy Ghost was given to the apostles for the working of miracles. This, however, is not a gift of sanctifying grace, but a gratuitous grace. Therefore the divine person is not given only according to the gift of sanctifying grace.

  On the contrary, Augustine says (De Trin. iii, 4) that "the Holy Ghost proceeds temporally for the creature's sanctification." But mission is a temporal procession. Since then the creature's sanctification is by sanctifying grace, it follows that the mission of the divine person is only by sanctifying grace.

  I answer that, The divine person is fittingly sent in the sense that He exists newly in any one; and He is given as possessed by anyone; and neither of these is otherwise than by sanctifying grace.

   For God is in all things by His essence, power and presence, according to His one common mode, as the cause existing in the effects which participate in His goodness. Above and beyond this common mode, however, there is one special mode belonging to the rational nature wherein God is said to be present as the object known is in the knower, and the beloved in the lover. And since the rational creature by its operation of knowledge and love attains to God Himself, according to this special mode God is said not only to exist in the rational creature but also to dwell therein as in His own temple. So no other effect can be put down as the reason why the divine person is in the rational creature in a new mode, except sanctifying grace. Hence, the divine person is sent, and proceeds temporally only according to sanctifying grace.

   Again, we are said to possess only what we can freely use or enjoy: and to have the power of enjoying the divine person can only be according to sanctifying grace. And yet the Holy Ghost is possessed by man, and dwells within him, in the very gift itself of sanctifying grace. Hence the Holy Ghost Himself is given and sent.

  Reply to Objection 1: By the gift of sanctifying grace the rational creature is perfected so that it can freely use not only the created gift itself, but enjoy also the divine person Himself; and so the invisible mission takes place according to the gift of sanctifying grace; and yet the divine person Himself is given.

  Reply to Objection 2: Sanctifying grace disposes the soul to possess the divine person; and this is signified when it is said that the Holy Ghost is given according to the gift of grace. Nevertheless the gift itself of grace is from the Holy Ghost; which is meant by the words, "the charity of God is poured forth in our hearts by the Holy Ghost."

  Reply to Objection 3: Although the Son can be known by us according to other effects, yet neither does He dwell in us, nor is He possessed by us according to those effects.

  Reply to Objection 4: The working of miracles manifests sanctifying grace as also does the gift of prophecy and any other gratuitous graces. Hence gratuitous grace is called the "manifestation of the Spirit" (1 Cor. 12:7). So the Holy Ghost is said to be given to the apostles for the working of miracles, because sanctifying grace was given to them with the outward sign. Were the sign only of sanctifying grace given to them without the grace itself, it would not be simply said that the Holy Ghost was given, except with some qualifying term; just as we read of certain ones receiving the gift of the spirit of prophecy, or of miracles, as having from the Holy Ghost the power of prophesying or of working miracles.

Whether the Father can be fittingly sent?

  Objection 1: It would seem that it is fitting also that the Father should be sent. For being sent means that the divine person is given. But the Father gives Himself since He can only be possessed by His giving Himself. Therefore it can be said that the Father sends Himself.

  Objection 2: Further, the divine person is sent according to the indwelling of grace. But by grace the whole Trinity dwells in us according to Jn. 14:23: "We will come to him and make Our abode with him." Therefore each one of the divine persons is sent.

  Objection 3: Further, whatever belongs to one person, belongs to them all, except the notions and persons. But mission does not signify any person; nor even a notion, since there are only five notions, as stated above (Question [32], Article [3]). Therefore every divine person can be sent.

  On the contrary, Augustine says (De Trin. ii, 3), "The Father alone is never described as being sent."

  I answer that, The very idea of mission means procession from another, and in God it means procession according to origin, as above expounded. Hence, as the Father is not from another, in no way is it fitting for Him to be sent; but this can only belong to the Son and to the Holy Ghost, to Whom it belongs to be from another.

  Reply to Objection 1: In the sense of "giving" as a free bestowal of something, the Father gives Himself, as freely bestowing Himself to be enjoyed by the creature. But as implying the authority of the giver as regards what is given, "to be given" only applies in God to the Person Who is from another; and the same as regards "being sent."

  Reply to Objection 2: Although the effect of grace is also from the Father, Who dwells in us by grace, just as the Son and the Holy Ghost, still He is not described as being sent, for He is not from another. Thus Augustine says (De Trin. iv, 20) that "The Father, when known by anyone in time, is not said to be sent; for there is no one whence He is, or from whom He proceeds."

  Reply to Objection 3: Mission, meaning procession from the sender, includes the signification of a notion, not of a special notion, but in general; thus "to be from another" is common to two of the notions.

Article: 5 

Whether it is fitting for the Son to be sent invisibly?

  Objection 1: It would seem that it is not fitting for the Son to be sent invisibly. For invisible mission of the divine person is according to the gift of grace. But all gifts of grace belong to the Holy Ghost, according to 1 Cor. 12:11: "One and the same Spirit worketh all things." Therefore only the Holy Ghost is sent invisibly.

  Objection 2: Further, the mission of the divine person is according to sanctifying grace. But the gifts belonging to the perfection of the intellect are not gifts of sanctifying grace, since they can be held without the gift of charity, according to 1 Cor. 13:2: "If I should have prophecy, and should know all mysteries, and all knowledge, and if I should have all faith so that I could move mountains, and have not charity, I am nothing." Therefore, since the Son proceeds as the word of the intellect, it seems unfitting for Him to be sent invisibly.

  Objection 3: Further, the mission of the divine person is a procession, as expounded above (Articles [1],4). But the procession of the Son and of the Holy Ghost differ from each other. Therefore they are distinct missions if both are sent; and then one of them would be superfluous, since one would suffice for the creature's sanctification.

  On the contrary, It is said of divine Wisdom (Wis. 9:10): "Send her from heaven to Thy Saints, and from the seat of Thy greatness."

  I answer that, The whole Trinity dwells in the mind by sanctifying grace, according to Jn. 14:23: "We will come to him, and will make Our abode with him." But that a divine person be sent to anyone by invisible grace signifies both that this person dwells in a new way within him and that He has His origin from another. Hence, since both to the Son and to the Holy Ghost it belongs to dwell in the soul by grace, and to be from another, it therefore belongs to both of them to be invisibly sent. As to the Father, though He dwells in us by grace, still it does not belong to Him to be from another, and consequently He is not sent.

  Reply to Objection 1: Although all the gifts, considered as such, are attributed to the Holy Ghost, forasmuch as He is by His nature the first Gift, since He is Love, as stated above (Question [38], Article [1]), some gifts nevertheless, by reason of their own particular nature, are appropriated in a certain way to the Son, those, namely, which belong to the intellect, and in respect of which we speak of the mission of the Son. Hence Augustine says (De Trin. iv, 20) that "The Son is sent to anyone invisibly, whenever He is known and perceived by anyone."

  Reply to Objection 2: The soul is made like to God by grace. Hence for a divine person to be sent to anyone by grace, there must needs be a likening of the soul to the divine person Who is sent, by some gift of grace. Because the Holy Ghost is Love, the soul is assimilated to the Holy Ghost by the gift of charity: hence the mission of the Holy Ghost is according to the mode of charity. Whereas the Son is the Word, not any sort of word, but one Who breathes forth Love. Hence Augustine says (De Trin. ix 10): "The Word we speak of is knowledge with love." Thus the Son is sent not in accordance with every and any kind of intellectual perfection, but according to the intellectual illumination, which breaks forth into the affection of love, as is said (Jn. 6:45): "Everyone that hath heard from the Father and hath learned, cometh to Me," and (Ps. 38:4): "In my meditation a fire shall flame forth." Thus Augustine plainly says (De Trin. iv, 20): "The Son is sent, whenever He is known and perceived by anyone." Now perception implies a certain experimental knowledge; and this is properly called wisdom [sapientia], as it were a sweet knowledge [sapida scientia], according to Ecclus. 6:23: "The wisdom of doctrine is according to her name."

  Reply to Objection 3: Since mission implies the origin of the person Who is sent, and His indwelling by grace, as above explained (Article [1]), if we speak of mission according to origin, in this sense the Son's mission is distinguished from the mission of the Holy Ghost, as generation is distinguished from procession. If we consider mission as regards the effect of grace, in this sense the two missions are united in the root which is grace, but are distinguished in the effects of grace, which consist in the illumination of the intellect and the kindling of the affection. Thus it is manifest that one mission cannot be without the other, because neither takes place without sanctifying grace, nor is one person separated from the other.
 
Article: 6 

Whether the invisible mission is to all who participate grace?

  Objection 1: It would seem that the invisible mission is not to all who participate grace. For the Fathers of the Old Testament had their share of grace. Yet to them was made no invisible mission; for it is said (Jn. 7:39): "The Spirit was not yet given, because Jesus was not yet glorified." Therefore the invisible mission is not to all partakers in grace.

  Objection 2: Further, progress in virtue is only by grace. But the invisible mission is not according to progress in virtue; because progress in virtue is continuous, since charity ever increases or decreases; and thus the mission would be continuous. Therefore the invisible mission is not to all who share in grace.

  Objection 3: Further, Christ and the blessed have fullness of grace. But mission is not to them, for mission implies distance, whereas Christ, as man, and all the blessed are perfectly united to God. Therefore the invisible mission is not to all sharers in grace.

  Objection 4: Further, the Sacraments of the New Law contain grace, and it is not said that the invisible mission is sent to them. Therefore the invisible mission is not to all that have grace.

  On the contrary, According to Augustine (De Trin. iii, 4; xv, 27), the invisible mission is for the creature's sanctification. Now every creature that has grace is sanctified. Therefore the invisible mission is to every such creature.

  I answer that, As above stated (Articles [3],4,5), mission in its very meaning implies that he who is sent either begins to exist where he was not before, as occurs to creatures; or begins to exist where he was before, but in a new way, in which sense mission is ascribed to the divine persons. Thus, mission as regards the one to whom it is sent implies two things, the indwelling of grace, and a certain renewal by grace. Thus the invisible mission is sent to all in whom are to be found these two conditions.

  Reply to Objection 1: The invisible mission was directed to the Old Testament Fathers, as appears from what Augustine says (De Trin. iv, 20), that the invisible mission of the Son "is in man and with men. This was done in former times with the Fathers and the Prophets." Thus the words, "the Spirit was not yet given," are to be applied to that giving accompanied with a visible sign which took place on the day of Pentecost.

  Reply to Objection 2: The invisible mission takes place also as regards progress in virtue or increase of grace. Hence Augustine says (De Trin. iv, 20), that "the Son is sent to each one when He is known and perceived by anyone, so far as He can be known and perceived according to the capacity of the soul, whether journeying towards God, or united perfectly to Him." Such invisible mission, however, chiefly occurs as regards anyone's proficiency in the performance of a new act, or in the acquisition of a new state of grace; as, for example, the proficiency in reference to the gift of miracles or of prophecy, or in the fervor of charity leading a man to expose himself to the danger of martyrdom, or to renounce his possessions, or to undertake any arduous work.

  Reply to Objection 3: The invisible mission is directed to the blessed at the very beginning of their beatitude. The invisible mission is made to them subsequently, not by "intensity" of grace, but by the further revelation of mysteries; which goes on till the day of judgment. Such an increase is by the "extension" of grace, because it extends to a greater number of objects. To Christ the invisible mission was sent at the first moment of His conception; but not afterwards, since from the beginning of His conception He was filled with all wisdom and grace.

  Reply to Objection 4: Grace resides instrumentally in the sacraments of the New Law, as the form of a thing designed resides in the instruments of the art designing, according to a process flowing from the agent to the passive object. But mission is only spoken of as directed to its term. Hence the mission of the divine person is not sent to the sacraments, but to those who receive grace through the sacraments.

Article: 7 

Whether it is fitting for the Holy Ghost to be sent visibly?

  Objection 1: It would seem that the Holy Ghost is not fittingly sent in a visible manner. For the Son as visibly sent to the world is said to be less than the Father. But the Holy Ghost is never said to be less than the Father. Therefore the Holy Ghost is not fittingly sent in a visible manner.

  Objection 2: Further, the visible mission takes place by way of union to a visible creature, as the Son's mission according to the flesh. But the Holy Ghost did not assume any visible creature; and hence it cannot be said that He exists otherwise in some creatures than in others, unless perhaps as in a sign, as He is also present in the sacraments, and in all the figures of the law. Thus the Holy Ghost is either not sent visibly at all, or His visible mission takes place in all these things.

  Objection 3: Further, every visible creature is an effect showing forth the whole Trinity. Therefore the Holy Ghost is not sent by reason of those visible creatures more than any other person.

  Objection 4: Further, the Son was visibly sent by reason of the noblest kind of creature---namely, the human nature. Therefore if the Holy Ghost is sent visibly, He ought to be sent by reason of rational creatures.

  Objection 5: Further, whatever is done visibly by God is dispensed by the ministry of the angels; as Augustine says (De Trin. iii, 4,5,9). So visible appearances, if there have been any, came by means of the angels. Thus the angels are sent, and not the Holy Ghost.

  Objection 6: Further, the Holy Ghost being sent in a visible manner is only for the purpose of manifesting the invisible mission; as invisible things are made known by the visible. So those to whom the invisible mission was not sent, ought not to receive the visible mission; and to all who received the invisible mission, whether in the New or in the Old Testament, the visible mission ought likewise to be sent; and this is clearly false. Therefore the Holy Ghost is not sent visibly.

  On the contrary, It is said (Mt. 3:16) that, when our Lord was baptized, the Holy Ghost descended upon Him in the shape of a dove.

  I answer that, God provides for all things according to the nature of each thing. Now the nature of man requires that he be led to the invisible by visible things, as explained above (Question [12], Article [12]). Wherefore the invisible things of God must be made manifest to man by the things that are visible. As God, therefore, in a certain way has demonstrated Himself and His eternal processions to men by visible creatures, according to certain signs; so was it fitting that the invisible missions also of the divine persons should be made manifest by some visible creatures.

   This mode of manifestation applies in different ways to the Son and to the Holy Ghost. For it belongs to the Holy Ghost, Who proceeds as Love, to be the gift of sanctification; to the Son as the principle of the Holy Ghost, it belongs to the author of this sanctification. Thus the Son has been sent visibly as the author of sanctification; the Holy Ghost as the sign of sanctification.

  Reply to Objection 1: The Son assumed the visible creature, wherein He appeared, into the unity of His person, so that whatever can be said of that creature can be said of the Son of God; and so, by reason of the nature assumed, the Son is called less than the Father. But the Holy Ghost did not assume the visible creature, in which He appeared, into the unity of His person; so that what is said of it cannot be predicated of Him. Hence He cannot be called less than the Father by reason of any visible creature.

  Reply to Objection 2: The visible mission of the Holy Ghost does not apply to the imaginary vision which is that of prophecy; because as Augustine says (De Trin. ii, 6): "The prophetic vision is not displayed to corporeal eyes by corporeal shapes, but is shown in the spirit by the spiritual images of bodies. But whoever saw the dove and the fire, saw them by their eyes. Nor, again, has the Holy Ghost the same relation to these images that the Son has to the rock, because it is said, "The rock was Christ" (1 Cor. 10:4). For that rock was already created, and after the manner of an action was named Christ, Whom it typified; whereas the dove and the fire suddenly appeared to signify only what was happening. They seem, however, to be like to the flame of the burning bush seen by Moses and to the column which the people followed in the desert, and to the lightning and thunder issuing forth when the law was given on the mountain. For the purpose of the bodily appearances of those things was that they might signify, and then pass away." Thus the visible mission is neither displayed by prophetic vision, which belongs to the imagination, and not to the body, nor by the sacramental signs of the Old and New Testament, wherein certain pre-existing things are employed to signify something. But the Holy Ghost is said to be sent visibly, inasmuch as He showed Himself in certain creatures as in signs especially made for that purpose.

  Reply to Objection 3: Although the whole Trinity makes those creatures, still they are made in order to show forth in some special way this or that person. For as the Father, Son and Holy Ghost are signified by diverse names, so also can They each one be signified by different things; although neither separation nor diversity exists amongst Them.

  Reply to Objection 4: It was necessary for the Son to be declared as the author of sanctification, as explained above. Thus the visible mission of the Son was necessarily made according to the rational nature to which it belongs to act, and which is capable of sanctification; whereas any other creature could be the sign of sanctification. Nor was such a visible creature, formed for such a purpose, necessarily assumed by the Holy Ghost into the unity of His person, since it was not assumed or used for the purpose of action, but only for the purpose of a sign; and so likewise it was not required to last beyond what its use required.

  Reply to Objection 5: Those visible creatures were formed by the ministry of the angels, not to signify the person of an angel, but to signify the Person of the Holy Ghost. Thus, as the Holy Ghost resided in those visible creatures as the one signified in the sign, on that account the Holy Ghost is said to be sent visibly, and not as an angel.

  Reply to Objection 6: It is not necessary that the invisible mission should always be made manifest by some visible external sign; but, as is said (1 Cor. 12:7)---"the manifestation of the Spirit is given to every man unto profit"---that is, of the Church. This utility consists in the confirmation and propagation of the faith by such visible signs. This has been done chiefly by Christ and by the apostles, according to Heb. 2:3, "which having begun to be declared by the Lord, was confirmed unto us by them that heard."

   Thus in a special sense, a mission of the Holy Ghost was directed to Christ, to the apostles, and to some of the early saints on whom the Church was in a way founded; in such a manner, however, that the visible mission made to Christ should show forth the invisible mission made to Him, not at that particular time, but at the first moment of His conception. The visible mission was directed to Christ at the time of His baptism by the figure of a dove, a fruitful animal, to show forth in Christ the authority of the giver of grace by spiritual regeneration; hence the Father's voice spoke, "This is My beloved Son" (Mt. 3:17), that others might be regenerated to the likeness of the only Begotten. The Transfiguration showed it forth in the appearance of a bright cloud, to show the exuberance of doctrine; and hence it was said, "Hear ye Him" (Mt. 17:5). To the apostles the mission was directed in the form of breathing to show forth the power of their ministry in the dispensation of the sacraments; and hence it was said, "Whose sins you shall forgive, they are forgiven" (Jn. 20:23): and again under the sign of fiery tongues to show forth the office of teaching; whence it is said that, "they began to speak with divers tongues" (Acts 2:4). The visible mission of the Holy Ghost was fittingly not sent to the fathers of the Old Testament, because the visible mission of the Son was to be accomplished before that of the Holy Ghost; since the Holy Ghost manifests the Son, as the Son manifests the Father. Visible apparitions of the divine persons were, however, given to the Fathers of the Old Testament which, indeed, cannot be called visible missions; because, according to Augustine (De Trin. ii, 17), they were not sent to designate the indwelling of the divine person by grace, but for the manifestation of something else.
 
Article: 8 

Whether a divine person is sent only by the person whence He proceeds eternally?

  Objection 1: It would seem that a divine person is sent only by the one whence He proceeds eternally. For as Augustine says (De Trin. iv), "The Father is sent by no one because He is from no one." Therefore if a divine person is sent by another, He must be from that other.

  Objection 2: Further, the sender has authority over the one sent. But there can be no authority as regards a divine person except from origin. Therefore the divine person sent must proceed from the one sending.

  Objection 3: Further, if a divine person can be sent by one whence He does not proceed, then the Holy Ghost may be given by a man, although He proceeds not from him; which is contrary to what Augustine says (De Trin. xv). Therefore the divine person is sent only by the one whence He proceeds.

  On the contrary, The Son is sent by the Holy Ghost, according to Is. 48:16, "Now the Lord God hath sent Me and His Spirit." But the Son is not from the Holy Ghost. Therefore a divine person is sent by one from Whom He does not proceed.

  I answer that, There are different opinions on this point. Some say that the divine person is sent only by the one whence He proceeds eternally; and so, when it is said that the Son of God is sent by the Holy Ghost, this is to be explained as regards His human nature, by reason of which He was sent to preach by the Holy Ghost. Augustine, however, says (De Trin. ii, 5) that the Son is sent by Himself, and by the Holy Ghost; and the Holy Ghost is sent by Himself, and by the Son; so that to be sent in God does not apply to each person, but only to the person proceeding from

   another, whereas to send belongs to each person.

   There is some truth in both of these opinions; because when a person is described as being sent, the person Himself existing from another is designated, with the visible or invisible effect, applicable to the mission of the divine person. Thus if the sender be designated as the principle of the person sent, in this sense not each person sends, but that person only Who is the principle of that person who is sent; and thus the Son is sent only by the Father; and the Holy Ghost by the Father and the Son. If, however, the person sending is understood as the principle of the effect implied in the mission, in that sense the whole Trinity sends the person sent. This reason does not prove that a man can send the Holy Ghost, forasmuch as man cannot cause the effect of grace.

   The answers to the objections appear from the above.

TREATISE ON THE CREATION (Questions 44-49)

Question: 44 THE PROCESSION OF CREATURES FROM GOD, AND OF THE FIRST CAUSE OF ALL THINGS (FOUR ARTICLES)

   After treating of the procession of the divine persons, we must consider the procession of creatures from God. This consideration will be threefold: (1) of the production of creatures; (2) of the distinction between them; (3) of their preservation and government. Concerning the first point there are three things to be considered: (1) the first cause of beings; (2) the mode of procession of creatures from the first cause; (3) the principle of the duration of things.

   Under the first head there are four points of inquiry:

    (1) Whether God is the efficient cause of all beings?

    (2) Whether primary matter is created by God, or is an independent coordinate principle with Him?

    (3) Whether God is the exemplar cause of beings or whether there are other exemplar causes?

    (4) Whether He is the final cause of things?
 
Article: 1 

Whether it is necessary that every being be created by God?

  Objection 1: It would seem that it is not necessary that every being be created by God. For there is nothing to prevent a thing from being without that which does not belong to its essence, as a man can be found without whiteness. But the relation of the thing caused to its cause does not appear to be essential to beings, for some beings can be understood without it; therefore they can exist without it; and therefore it is possible that some beings should not be created by God.

  Objection 2: Further, a thing requires an efficient cause in order to exist. Therefore whatever cannot but exist does not require an efficient cause. But no necessary thing can not exist, because whatever necessarily exists cannot but exist. Therefore as there are many necessary things in existence, it appears that not all beings are from God.

  Objection 3: Further, whatever things have a cause, can be demonstrated by that cause. But in mathematics demonstration is not made by the efficient cause, as appears from the Philosopher (Metaph. iii, text 3); therefore not all beings are from God as from their efficient cause.

  On the contrary, It is said (Rm. 11:36): "Of Him, and by Him, and in Him are all things."

  I answer that, It must be said that every being in any way existing is from God. For whatever is found in anything by participation, must be caused in it by that to which it belongs essentially, as iron becomes ignited by fire. Now it has been shown above (Question [3], Article [4]) when treating of the divine simplicity that God is the essentially self-subsisting Being; and also it was shown (Question [11], Articles [3],4) that subsisting being must be one; as, if whiteness were self-subsisting, it would be one, since whiteness is multiplied by its recipients. Therefore all beings apart from God are not their own being, but are beings by participation. Therefore it must be that all things which are diversified by the diverse participation of being, so as to be more or less perfect, are caused by one First Being, Who possesses being most perfectly.

   Hence Plato said (Parmen. xxvi) that unity must come before multitude; and Aristotle said (Metaph. ii, text 4) that whatever is greatest in being and greatest in truth, is the cause of every being and of every truth; just as whatever is the greatest in heat is the cause of all heat.

  Reply to Objection 1: Though the relation to its cause is not part of the definition of a thing caused, still it follows, as a consequence, on what belongs to its essence; because from the fact that a thing has being by participation, it follows that it is caused. Hence such a being cannot be without being caused, just as man cannot be without having the faculty of laughing. But, since to be caused does not enter into the essence of being as such, therefore is it possible for us to find a being uncaused.

  Reply to Objection 2: This objection has led some to say that what is necessary has no cause (Phys. viii, text 46). But this is manifestly false in the demonstrative sciences, where necessary principles are the causes of necessary conclusions. And therefore Aristotle says (Metaph. v, text 6), that there are some necessary things which have a cause of their necessity. But the reason why an efficient cause is required is not merely because the effect is not necessary, but because the effect might not be if the cause were not. For this conditional proposition is true, whether the antecedent and consequent be possible or impossible.

  Reply to Objection 3: The science of mathematics treats its object as though it were something abstracted mentally, whereas it is not abstract in reality. Now, it is becoming that everything should have an efficient cause in proportion to its being. And so, although the object of mathematics has an efficient cause, still, its relation to that cause is not the reason why it is brought under the consideration of the mathematician, who therefore does not demonstrate that object from its efficient cause.
 
Article: 2 

Whether primary matter is created by God?

  Objection 1: It would seem that primary matter is not created by God. For whatever is made is composed of a subject and of something else (Phys. i, text 62). But primary matter has no subject. Therefore primary matter cannot have been made by God.

  Objection 2: Further, action and passion are opposite members of a division. But as the first active principle is God, so the first passive principle is matter. Therefore God and primary matter are two principles divided against each other, neither of which is from the other.

  Objection 3: Further, every agent produces its like, and thus, since every agent acts in proportion to its actuality, it follows that everything made is in some degree actual. But primary matter is only in potentiality, formally considered in itself. Therefore it is against the nature of primary matter to be a thing made.

  On the contrary, Augustine says (Confess. xii, 7), Two "things hast Thou made, O Lord; one nigh unto Thyself"---viz. angels---"the other nigh unto nothing"---viz. primary matter.

  I answer that, The ancient philosophers gradually, and as it were step by step, advanced to the knowledge of truth. At first being of grosser mind, they failed to realize that any beings existed except sensible bodies. And those among them who admitted movement, did not consider it except as regards certain accidents, for instance, in relation to rarefaction and condensation, by union and separation. And supposing as they did that corporeal substance itself was uncreated, they assigned certain causes for these accidental changes, as for instance, affinity, discord, intellect, or something of that kind. An advance was made when they understood that there was a distinction between the substantial form and matter, which latter they imagined to be uncreated, and when they perceived transmutation to take place in bodies in regard to essential forms. Such transmutations they attributed to certain universal causes, such as the oblique circle [*The zodiac], according to Aristotle (De Gener. ii), or ideas, according to Plato. But we must take into consideration that matter is contracted by its form to a determinate species, as a substance, belonging to a certain species, is contracted by a supervening accident to a determinate mode of being; for instance, man by whiteness. Each of these opinions, therefore, considered "being" under some particular aspect, either as "this" or as "such"; and so they assigned particular efficient causes to things. Then others there were who arose to the consideration of "being," as being, and who assigned a cause to things, not as "these," or as "such," but as "beings."

   Therefore whatever is the cause of things considered as beings, must be the cause of things, not only according as they are "such" by accidental forms, nor according as they are "these" by substantial forms, but also according to all that belongs to their being at all in any way. And thus it is necessary to say that also primary matter is created by the universal cause of things.

  Reply to Objection 1: The Philosopher (Phys. i, text 62), is speaking of "becoming" in particular---that is, from form to form, either accidental or substantial. But here we are speaking of things according to their emanation from the universal principle of being; from which emanation matter itself is not excluded, although it is excluded from the former mode of being made.

  Reply to Objection 2: Passion is an effect of action. Hence it is reasonable that the first passive principle should be the effect of the first active principle, since every imperfect thing is caused by one perfect. For the first principle must be most perfect, as Aristotle says (Metaph. xii, text 40).

  Reply to Objection 3: The reason adduced does not show that matter is not created, but that it is not created without form; for though everything created is actual, still it is not pure act. Hence it is necessary that even what is potential in it should be created, if all that belongs to its being is created.

Article: 3 

Whether the exemplar cause is anything besides God?

  Objection 1: It would seem that the exemplar cause is something besides God. For the effect is like its exemplar cause. But creatures are far from being like God. Therefore God is not their exemplar cause.

  Objection 2: Further, whatever is by participation is reduced to something self-existing, as a thing ignited is reduced to fire, as stated above (Article [1]). But whatever exists in sensible things exists only by participation of some species. This appears from the fact that in all sensible species is found not only what belongs to the species, but also individuating principles added to the principles of the species. Therefore it is necessary to admit self-existing species, as for instance, a "per se" man, and a "per se" horse, and the like, which are called the exemplars. Therefore exemplar causes exist besides God.

  Objection 3: Further, sciences and definitions are concerned with species themselves, but not as these are in particular things, because there is no science or definition of particular things. Therefore there are some beings, which are beings or species not existing in singular things, and these are called exemplars. Therefore the same conclusion follows as above.

  Objection 4: Further, this likewise appears from Dionysius, who says (Div. Nom. v) that self-subsisting being is before self-subsisting life, and before self-subsisting wisdom.

  On the contrary, The exemplar is the same as the idea. But ideas, according to Augustine (Questions. 83, qu. 46), are "the master forms, which are contained in the divine intelligence." Therefore the exemplars of things are not outside God.

  I answer that, God is the first exemplar cause of all things. In proof whereof we must consider that if for the production of anything an exemplar is necessary, it is in order that the effect may receive a determinate form. For an artificer produces a determinate form in matter by reason of the exemplar before him, whether it is the exemplar beheld externally, or the exemplar interiorily conceived in the mind. Now it is manifest that things made by nature receive determinate forms. This determination of forms must be reduced to the divine wisdom as its first principle, for divine wisdom devised the order of the universe, which order consists in the variety of things. And therefore we must say that in the divine wisdom are the types of all things, which types we have called ideas---i.e. exemplar forms existing in the divine mind (Question [15], Article [1]). And these ideas, though multiplied by their relations to things, in reality are not apart from the divine essence, according as the likeness to that essence can be shared diversely by different things. In this manner therefore God Himself is the first exemplar of all things. Moreover, in things created one may be called the exemplar of another by the reason of its likeness thereto, either in species, or by the analogy of some kind of imitation.

  Reply to Objection 1: Although creatures do not attain to a natural likeness to God according to similitude of species, as a man begotten is like to the man begetting, still they do attain to likeness to Him, forasmuch as they represent the divine idea, as a material house is like to the house in the architect's mind.

  Reply to Objection 2: It is of a man's nature to be in matter, and so a man without matter is impossible. Therefore although this particular man is a man by participation of the species, he cannot be reduced to anything self-existing in the same species, but to a superior species, such as separate substances. The same applies to other sensible things.

  Reply to Objection 3: Although every science and definition is concerned only with beings, still it is not necessary that a thing should have the same mode in reality as the thought of it has in our understanding. For we abstract universal ideas by force of the active intellect from the particular conditions; but it is not necessary that the universals should exist outside the particulars in order to be their exemplars.

  Reply to Objection 4: As Dionysius says (Div. Nom. iv), by "self-existing life and self-existing wisdom" he sometimes denotes God Himself, sometimes the powers given to things themselves; but not any self-subsisting things, as the ancients asserted.

Whether God is the final cause of all things?

  Objection 1: It would seem that God is not the final cause of all things. For to act for an end seems to imply need of the end. But God needs nothing. Therefore it does not become Him to act for an end.

  Objection 2: Further, the end of generation, and the form of the thing generated, and the agent cannot be identical (Phys. ii, text 70), because the end of generation is the form of the thing generated. But God is the first agent producing all things. Therefore He is not the final cause of all things.

  Objection 3: Further, all things desire their end. But all things do not desire God, for all do not even know Him. Therefore God is not the end of all things.

  Objection 4: Further, the final cause is the first of causes. If, therefore, God is the efficient cause and the final cause, it follows that before and after exist in Him; which is impossible.

  On the contrary, It is said (Prov. 16:4): "The Lord has made all things for Himself."

  I answer that, Every agent acts for an end: otherwise one thing would not follow more than another from the action of the agent, unless it were by chance. Now the end of the agent and of the patient considered as such is the same, but in a different way respectively. For the impression which the agent intends to produce, and which the patient intends to receive, are one and the same. Some things, however, are both agent and patient at the same time: these are imperfect agents, and to these it belongs to intend, even while acting, the acquisition of something. But it does not belong to the First Agent, Who is agent only, to act for the acquisition of some end; He intends only to communicate His perfection, which is His goodness; while every creature intends to acquire its own perfection, which is the likeness of the divine perfection and goodness. Therefore the divine goodness is the end of all things.

  Reply to Objection 1: To act from need belongs only to an imperfect agent, which by its nature is both agent and patient. But this does not belong to God, and therefore He alone is the most perfectly liberal giver, because He does not act for His own profit, but only for His own goodness.

  Reply to Objection 2: The form of the thing generated is not the end of generation, except inasmuch as it is the likeness of the form of the generator, which intends to communicate its own likeness; otherwise the form of the thing generated would be more noble than the generator, since the end is more noble than the means to the end.

  Reply to Objection 3: All things desire God as their end, when they desire some good thing, whether this desire be intellectual or sensible, or natural, i.e. without knowledge; because nothing is good and desirable except forasmuch as it participates in the likeness to God.

  Reply to Objection 4: Since God is the efficient, the exemplar and the final cause of all things, and since primary matter is from Him, it follows that the first principle of all things is one in reality. But this does not prevent us from mentally considering many things in Him, some of which come into our mind before others.

Question: 45 THE MODE OF EMANATION OF THINGS FROM THE FIRST PRINCIPLE (EIGHT ARTICLES)

   The next question concerns the mode of the emanation of things from the First Principle, and this is called creation, and includes eight points of inquiry:

    (1) What is creation?

    (2) Whether God can create anything?

    (3) Whether creation is anything in the very nature of things?

    (4) To what things it belongs to be created?

    (5) Whether it belongs to God alone to create?

    (6) Whether creation is common to the whole Trinity, or proper to any one Person?

    (7) Whether any trace of the Trinity is to be found in created things?

    (8) Whether the work of creation is mingled with the works of nature and of the will?

Whether to create is to make something from nothing?

  Objection 1: It would seem that to create is not to make anything from nothing. For Augustine says (Contra Adv. Leg. et Proph. i): "To make concerns what did not exist at all; but to create is to make something by bringing forth something from what was already."

  Objection 2: Furthe
