SIXTH ARTICLE: WHETHER IT WAS FITTING FOR THE SON OF GOD TO ASSUME HUMAN NATURE OF THE STOCK OF ADAM

The Son of God could, indeed, have assumed the human nature created anew, just as Adam was created.

Reply. The answer is, nevertheless, that it was fitting for the Son of God to assume the human nature of the stock of Adam, and this for three reasons: 1. so that He might satisfy for the race that had sinned; 2. because the conqueror of the devil should come from the race conquered by the devil; 3. to manifest God's omnipotence that. raised a weakened and corrupt nature to such virtue and dignity. God permits evil only for a greater good.

Hence in the Roman Breviary, the Church recites: "That flesh hath purged, what flesh hath stained."[715] The Scripture says: "Who can make him clean that is conceived of unclean seed. Is it not Thou who only art?"[716] Thus there are sinners in Christ's genealogy, although He is separated from sinners in this respect.

Reply to first objection. Christ's innocence is the more wonderful in this, that, although He assumed His nature from a mass tainted by sin, it was endowed with such purity.

Reply to second objection. It was not fitting for the Word to assume the particular nature of Adam, who was a sinner; because Christ, who had come to cleanse all sinners, had to be separated from all who sinned.

Third objection. The difficulty is this: "If the Son of God wished to assume human nature from sinners, He ought rather to have assumed it from the Gentiles than from the stock of Abraham, who was just."

Reply to third objection. Christ, indeed, had to be like sinners in His assumed nature, but He also had to be separated from them as regards sin. Hence it was fitting that between the first sinner and Christ, some just men should intervene, who were to be in certain respects conspicuous types of Christ's future holiness, and these began in Abraham.

But why the Jewish race was chosen in preference to any of the Gentile nations depends on God's absolute free choice, just as the predestination of Christ, of His Blessed Mother, of Abraham, Isaac, Jacob, and the prophets are so dependent. The mystery of predestination is apparent in the whole course of Jewish history, since one is chosen in preference to another, for instance, Abel to Cain, Noe to those who died in the flood, Isaac to another son of Abraham, Jacob to Esau; and so it is with other descendants. It must be noted that the merits of the elect are not the cause of their predestination, because they are its effects. This is especially evident both as regards Christ's predestination to divine natural sonship, and the predestination of the Blessed Virgin Mary to divine maternity.

Supplementary Questions

First doubt. Does the human nature united with the Word still have an innate desire for its own subsistence?

Reply. The common opinion of the Thomists, especially of Cajetan and John of St. Thomas, is that it has no such desire as a reflected act (actus secundus), because it is perfected by a more perfect subsistence, which contains formally and eminently absolutely whatever there would be in its own subsistence. Therefore the natural desire of the assumed human nature rests satisfied in the higher subsistence.[717]

Second doubt. Can incomplete substances and accidents be assumed immediately by the Word, such as prime matter, non-subsistent forms, for instance, the substantial form of bread, or of another body?

Reply. The query is denied, because these incomplete realities are intrinsically incapable of having their own subsistences. Thus prime matter, the substantial form of bread, and accidents cannot be assumed except mediately, that is, through the mediation of substance, whose parts they are, or in which they inhere. But the rational soul separated from the body, which is capable of having its own subsistence and existence, is assumable.

Corollary. Integral parts of the human body, such as the hand, the head, feet, so long as they are united to the whole, cannot be assumed unless the whole is assumed. But if these parts are separated by death, they can remain united with the Word, because these parts separated from the whole are capable of having their own subsistence and existence, distinct from the subsistence and existence of the whole.
