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

Reply Obj. 1: Christ is said to be a natural Son of Man, by reason of His having a true human nature, through which He is a Son of Man, although He had it miraculously; thus, too, the blind man to whom sight has been restored sees naturally by sight miraculously received.

Reply Obj. 2: The conception is attributed to the Blessed Virgin, not as the active principle thereof, but because she supplied the matter, and because the conception took place in her womb.

Reply Obj. 3: A natural passive principle suffices for a transformation to be natural, when it is moved by its proper active principle in a natural and wonted way. But this is not so in the case in point. Therefore this conception cannot be called simply natural.

We must now consider the perfection of the child conceived: and concerning this there are four points of inquiry:

(1) Whether Christ was sanctified by grace in the first instant of His conception?

(2) Whether in that same instant He had the use of free-will?

(3) Whether in that same instant He could merit?

(4) Whether in that same instant He was a perfect comprehensor? _______________________

FIRST ARTICLE [III, Q. 34, Art. 1]

Whether Christ Was Sanctified in the First Instant of His Conception?

Objection 1: It would seem that Christ was not sanctified in the first instant of His conception. For it is written (1 Cor. 15:46): "That was not first which is spiritual, but that which is natural: afterwards that which is spiritual." But sanctification by grace is something spiritual. Therefore Christ received the grace of sanctification, not at the very beginning of His conception, but after a space of time.

Obj. 2: Further, sanctification seems to be a cleansing from sin: according to 1 Cor. 6:1: "And such some of you were," namely, sinners, "but you are washed, but you are sanctified." But sin was never in Christ. Therefore it was not becoming that He should be sanctified by grace.

Obj. 3: Further, as by the Word of God "all things were made," so from the Word incarnate all men who are made holy receive holiness, according to Heb. 2:11: "Both he that sanctifieth and they who are sanctified are all of one." But "the Word of God, by whom all things were made, was not Himself made"; as Augustine says (De Trin. i). Therefore Christ, by whom all are made holy, was not Himself made holy.

On the contrary, It is written (Luke 1:35): "The Holy which shall be born of thee shall be called the Son of God"; and (John 10:36): "Whom the Father hath sanctified and sent into the world."

I answer that, As stated above (Q. 7, AA. 9, 10, 12), the abundance of grace sanctifying Christ's soul flows from the very union of the Word, according to John 1:14: "We saw His glory . . . as it were of the Only-Begotten of the Father, full of grace and truth." For it has been shown above (Q. 33, AA. 2, 3) that in the first instant of conception, Christ's body was both animated and assumed by the Word of God. Consequently, in the first instant of His conception, Christ had the fulness of grace sanctifying His body and His soul.

Reply Obj. 1: The order set down by the Apostle in this passage refers to those who by advancing attain to the spiritual state. But the mystery of the Incarnation is considered as a condescension of the fulness of the Godhead into human nature rather than as the promotion of human nature, already existing, as it were, to the Godhead. Therefore in the man Christ there was perfection of spiritual life from the very beginning.

Reply Obj. 2: To be sanctified is to be made holy. Now something is made not only from its contrary, but also from that which is opposite to it, either by negation or by privation: thus white is made either from black or from not-white. We indeed from being sinners are made holy: so that our sanctification is a cleansing from sin. Whereas Christ, as man, was made holy, because He was not always thus sanctified by grace: yet He was not made holy from being a sinner, because He never sinned; but He was made holy from not-holy as man, not indeed by privation, as though He were at some time a man and not holy; but by negation—that is, when He was not man He had not human sanctity. Therefore at the same time He was made man and a holy man. For this reason the angel said (Luke 1:35): "The Holy which shall be born of thee." Which words Gregory expounds as follows (Moral. xviii): "In order to show the distinction between His holiness and ours, it is declared that He shall be born holy. For we, though we are made holy, yet are not born holy, because by the mere condition of a corruptible nature we are tied . . . But He alone is truly born holy who . . . was not conceived by the combining of carnal union."

Reply Obj. 3: The Father creates things through the Son, and the whole Trinity sanctifies men through the Man Christ, but not in the same way. For the Word of God has the same power and operation as God the Father: hence the Father does not work through the Son as an instrument, which is both mover and moved. Whereas the humanity of Christ is as the instrument of the Godhead, as stated above (Q. 7, A. 1, ad 3; Q. 8, A. 1, ad 1). Therefore Christ's humanity is both sanctified and sanctifier. _______________________

SECOND ARTICLE [III, Q. 34, Art. 2]

Whether Christ As Man Had the Use of Free-will in the First Instant of His Conception?

Objection 1: It would seem that Christ as man had not the use of free-will in the first instant of His conception. For a thing is, before it acts or operates. Now the use of free-will is an operation. Since, therefore, Christ's soul began to exist in the first instant of His conception, as was made clear above (Q. 33, A. 2), it seems impossible that He should have the use of free-will in the first instant of His conception.

Obj. 2: Further, the use of free-will consists in choice. But choice presupposes the deliberation of counsel: for the Philosopher says (Ethic. iii) that choice is "the desire of what has been previously the object of deliberation." Therefore it seems impossible that Christ should have had the use of free-will in the first instant of His conception.

Obj. 3: Further, the free-will is "a faculty of the will and reason," as stated in the First Part (Q. 83, A. 2, Obj. 2): consequently the use of free-will is an act of the will and the reason or intellect. But the act of the intellect presupposes an act of the senses; and this cannot exist without proper disposition of the organs—a condition which would seem impossible in the first instant of Christ's conception. Therefore it seems that Christ could not have the use of free-will at the first instant of His conception.

On the contrary, Augustine says in his book on the Trinity (Gregory: Regist. ix, Ep. 61): "As soon as the Word entered the womb, while retaining the reality of His Nature, He was made flesh, and a perfect man." But a perfect man has the use of free-will. Therefore Christ had the use of free-will in the first instant of His conception.

I answer that, As stated above (A. 1), spiritual perfection was becoming to the human nature which Christ took, which perfection He attained not by making progress, but by receiving it from the very first. Now ultimate perfection does not consist in power or habit, but in operation; wherefore it is said (De Anima ii, text. 5) that operation is a "second act." We must, therefore, say that in the first instant of His conception Christ had that operation of the soul which can be had in an instant. And such is the operation of the will and intellect, in which the use of free-will consists. For the operation of the intellect and will is sudden and instantaneous, much more, indeed, than corporeal vision; inasmuch as to understand, to will, and to feel, are not movements that may be described as "acts of an imperfect being," which attains perfection successively, but are "the acts of an already perfect being," as is said, De Anima iii, text. 28. We must therefore say that Christ had the use of free-will in the first instant of His conception.
