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.
Obj. 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.
Obj. 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.
Obj. 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 (Q. 41, A. 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 (Q. 41, A. 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 Obj. 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 Obj. 2: Eternity excludes the principle of duration, but not the principle of origin.
Reply Obj. 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 (Q. 27, A. 2). Hence the Son is ever being begotten, and the Father is always begetting.
Reply Obj. 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 (Q. 10, A. 2, ad 1; A. 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.
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.
Obj. 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.
Obj. 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.
Obj. 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 (Q. 33, A. 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 Obj. 1: The order of nature signifies the notion of origin in general, not a special kind of origin.
Reply Obj. 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 Obj. 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 Obj. 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.
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 (John 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."
Obj. 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.
Obj. 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 (Q. 27, A. 2; Q. 33, AA. 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 Obj. 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 Obj. 2: Equality is measured by greatness. In God greatness signifies the perfection of nature, as above explained (A. 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 Obj. 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. Person likewise is not a universal term in God as we have seen above (Q. 30, A. 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.
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.
Obj. 2: Further, nothing that has come out from another is within.
But the Son from eternity came out from the Father, according to Mic.
5:2: "His going forth is from the beginning, from the days of eternity." Therefore the Son is not in the Father.
Obj. 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 (John 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 Obj. 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 Obj. 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 Obj. 3: The Father and the Son are relatively opposed, but not essentially; while, as above explained, one relative opposite is in the other.
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 (John 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.
Obj. 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 John 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" (John 5:20). Also, the Son hears: "As I hear, so I judge" (John 5:30). Therefore the Father has greater power than the Son.
Obj. 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 (Q. 41, A. 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 (John 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 (A. 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 Obj. 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 Obj. 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 Obj. 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 (In 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?
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.
Obj. 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.
Obj. 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 (John 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" (John 1:1).
Reply Obj. 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 (Q. 42, AA. 4, 6).
Reply Obj. 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 Obj. 3: This objection rests on the idea of mission according to local motion, which is not in God.
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.
Obj. 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.
Obj. 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 Obj. 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 Obj. 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 Obj. 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.
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.
Obj. 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 Rom. 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.
Obj. 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.
Obj. 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 Obj. 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 Obj. 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 Obj. 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 Obj. 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.
Obj. 2: Further, the divine person is sent according to the indwelling of grace. But by grace the whole Trinity dwells in us according to John 14:23: "We will come to him and make Our abode with him." Therefore each one of the divine persons is sent.
Obj. 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 (Q. 32, A. 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 Obj. 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 Obj. 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 Obj. 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.
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.
Obj. 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.
Obj. 3: Further, the mission of the divine person is a procession, as expounded above (AA. 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 John 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.
