Against Heresies (Book III, Chapter 22)
1. Those, therefore, who allege that [our Lord Jesus] took nothing from the Virgin do greatly err, since, in order that they may cast away the inheritance of the flesh, they also reject the analogy [between Him and Adam]. For if the one who sprang from the earth had indeed formation and substance from both the hand and workmanship of God, but the other not from the hand and workmanship of God, then He who was made after the image and likeness of the former did not, in that case, preserve the analogy of man, and He must seem an inconsistent piece of work, not having wherewith He may show His wisdom. But this is to say, that He also appeared putatively as man when He was not man, and that He was made man while taking nothing from man. For if He did not receive the substance of flesh from a human being, He neither was made man nor the Son of man; and if He was not made what we were, He did no great thing in what He suffered and endured. But every one will allow that we are [composed of] a body taken from the earth, and a soul receiving spirit from God. This, therefore, the Word of God was made, recapitulating in Himself His own handiwork; and on this account does He confess Himself the Son of man, and blesses "the meek, because they shall inherit the earth" (Matt. 5:5). The Apostle Paul, moreover, in the Epistle to the Galatians, declares plainly, "God sent His Son, made of a woman" (Gal. 4:4). And again, in that to the Romans, he says, "Concerning His Son, who was made of the seed of David according to the flesh, who was predestinated as the Son of God with power, according to the spirit of holiness, by the resurrection from the dead, Jesus Christ our Lord" (Rom. 1:3-4).
