Thomas Aquinas - Summa Theologica, Part III (Tertia Pars)

Reply Obj. 1: From these words nothing may be gathered, except that the Word, by assuming the parts of human nature, assumed the whole human nature. And thus the assumption of parts is prior in the order of the intellect, if we consider the operation, but not in order of time; whereas the assumption of the nature is prior if we consider the intention: and this is to be simply first, as was said above.

Reply Obj. 2: God is so simple that He is also most perfect; and hence the whole is more like to God than the parts, inasmuch as it is more perfect.

Reply Obj. 3: It is a personal union wherein the assumption is terminated, not a union of nature, which springs from a conjunction of parts. _______________________

SIXTH ARTICLE [III, Q. 6, Art. 6]

Whether the Human Nature Was Assumed Through the Medium of Grace?

Objection 1: It would seem that the Son of God assumed human nature through the medium of grace. For by grace we are united to God. But the human nature in Christ was most closely united to God. Therefore the union took place by grace.

Obj. 2: Further, as the body lives by the soul, which is its perfection, so does the soul by grace. But the human nature was fitted for the assumption by the soul. Therefore the Son of God assumed the soul through the medium of grace.

Obj. 3: Further, Augustine says (De Trin. xv, 11) that the incarnate Word is like our spoken word. But our word is united to our speech by means of breathing ( spiritus ). Therefore the Word of God is united to flesh by means of the Holy Spirit, and hence by means of grace, which is attributed to the Holy Spirit, according to 1 Cor. 12:4: "Now there are diversities of graces, but the same Spirit."

On the contrary, Grace is an accident in the soul, as was shown above (I-II, Q. 110, A. 2). Now the union of the Word with human nature took place in the subsistence, and not accidentally, as was shown above (Q. 2, A. 6). Therefore the human nature was not assumed by means of grace.

I answer that, In Christ there was the grace of union and habitual grace. Therefore grace cannot be taken to be the medium of the assumption of the human nature, whether we speak of the grace of union or of habitual grace. For the grace of union is the personal being that is given gratis from above to the human nature in the Person of the Word, and is the term of the assumption. Whereas the habitual grace pertaining to the spiritual holiness of the man is an effect following the union, according to John 1:14: "We saw His glory . . . as it were of the Only-begotten of the Father, full of grace and truth"—by which we are given to understand that because this Man (as a result of the union) is the Only-begotten of the Father, He is full of grace and truth. But if by grace we understand the will of God doing or bestowing something gratis, the union took place by grace, not as a means, but as the efficient cause.

Reply Obj. 1: Our union with God is by operation, inasmuch as we know and love Him; and hence this union is by habitual grace, inasmuch as a perfect operation proceeds from a habit. Now the union of the human nature with the Word of God is in personal being, which depends not on any habit, but on the nature itself.

Reply Obj. 2: The soul is the substantial perfection of the body; grace is but an accidental perfection of the soul. Hence grace cannot ordain the soul to personal union, which is not accidental, as the soul ordains the body.

Reply Obj. 3: Our word is united to our speech, by means of breathing ( spiritus ), not as a formal medium, but as a moving medium. For from the word conceived within, the breathing proceeds, from which the speech is formed. And similarly from the eternal Word proceeds the Holy Spirit, Who formed the body of Christ, as will be shown (Q. 32, A. 1). But it does not follow from this that the grace of the Holy Spirit is the formal medium in the aforesaid union.

We must now consider such things as were co-assumed by the Son of God in human nature; and first what belongs to perfection; secondly, what belongs to defect.

Concerning the first, there are three points of consideration: (1) The grace of Christ; (2) His knowledge; (3) His power.

With regard to His grace we must consider two things: (1) His grace as

He is an individual man; (2) His grace as He is the Head of the

Church. Of the grace of union we have already spoken (Q. 2).

Under the first head there are thirteen points of inquiry:

(1) Whether in the soul of Christ there was any habitual grace?

(2) Whether in Christ there were virtues?

(3) Whether He had faith?

(4) Whether He had hope?

(5) Whether in Christ there were the gifts?

(6) Whether in Christ there was the gift of fear?

(7) Whether in Christ there were any gratuitous graces?

(8) Whether in Christ there was prophecy?

(9) Whether there was the fulness of grace in Him?

(10) Whether such fulness was proper to Christ?

(11) Whether the grace of Christ was infinite?

(12) Whether it could have been increased?

(13) How this grace stood towards the union? _______________________

FIRST ARTICLE [III, Q. 7, Art. 1]

Whether in the Soul of Christ There Was Any Habitual Grace?

Objection 1: It would seem there was no habitual grace in the soul assumed by the Word. For grace is a certain partaking of the Godhead by the rational creature, according to 2 Pet. 1:4: "By Whom He hath given us most great and precious promises, that by these you may be made partakers of the Divine Nature." Now Christ is God not by participation, but in truth. Therefore there was no habitual grace in Him.

Obj. 2: Further, grace is necessary to man, that he may operate well, according to 1 Cor. 15:10: "I have labored more abundantly than all they; yet not I, but the grace of God with me"; and in order that he may reach eternal life, according to Rom. 6:23: "The grace of God (is) life everlasting." Now the inheritance of everlasting life was due to Christ by the mere fact of His being the natural Son of God; and by the fact of His being the Word, by Whom all things were made, He had the power of doing all things well. Therefore His human nature needed no further grace beyond union with the Word.

Obj. 3: Further, what operates as an instrument does not need a habit for its own operations, since habits are rooted in the principal agent. Now the human nature in Christ was "as the instrument of the Godhead," as Damascene says (De Fide Orth. iii, 15). Therefore there was no need of habitual grace in Christ.

On the contrary, It is written (Isa. 11:2): "The Spirit of the Lord shall rest upon Him"—which (Spirit), indeed, is said to be in man by habitual grace, as was said above (I, Q. 8, A. 3; Q. 43, AA. 3, 6). Therefore there was habitual grace in Christ.

I answer that, It is necessary to suppose habitual grace in Christ for three reasons. First, on account of the union of His soul with the Word of God. For the nearer any recipient is to an inflowing cause, the more does it partake of its influence. Now the influx of grace is from God, according to Ps. 83:12: "The Lord will give grace and glory." And hence it was most fitting that His soul should receive the influx of Divine grace. Secondly, on account of the dignity of this soul, whose operations were to attain so closely to God by knowledge and love, to which it is necessary for human nature to be raised by grace. Thirdly, on account of the relation of Christ to the human race. For Christ, as man, is the "Mediator of God and men," as is written, 1 Tim. 2:5; and hence it behooved Him to have grace which would overflow upon others, according to John 1:16: "And of His fulness we have all received, and grace for grace."
