If birth is something evil, let the blasphemers say that the Lord who shared in birth was born in evil, and that the virgin gave birth to him in evil. Woe to these wicked fellows! They blaspheme against the will of God and the mystery of creation in speaking evil of birth. This is the ground upon which Docetism is held by Cassian and by Marcion also, and on which even Valentine indeed teaches that Christ's body was "psychic." They say: Man became like the beasts when he came to practice sexual intercourse. But it is when a man in his passion really wants to go to bed with a strange woman that in truth such a man has become a wild beast. "Wild horses were they become, each man whinnied after his neighbour's wife." And if the serpent took the use of intercourse from the irrational animals and persuaded Adam to agree to have sexual union with Eve, as though the couple first created did not have such union by nature, as some think, this again is blasphemy against the creation. For it makes human nature weaker than that of the brute beasts if in this matter those who were first created by God copied them.

But if nature led them, like the irrational animals, to procreation, yet they were impelled to do it more quickly than. was proper because they were still young and had been led away by deceit. Thus God's judgment against them was just, because they did not wait for his will. But birth is holy. By it were made the world, the existences, the natures, the angels, powers, souls, the commandments, the law, the gospel, the knowledge of God. And "all flesh is grass, and all the glory of man as the flower of grass. The grass withers, the flower falls; but the word of the Lord abides" which anoints the soul and unites it with the spirit. Without the body how could the divine plan for us in the Church achieve its end? Surely the Lord himself, the head of the Church, came in the flesh, though without form and beauty, to teach us to look upon the formless and incorporeal nature of the divine Cause. "For a tree of life" says the prophet, "grows by a good desire," teaching that desires which are in the living Lord are good and pure.

Furthermore they wish to maintain that the intercourse of man and wife in marriage, which is called knowledge, is a sin; this sin is referred to as eating of the tree of good and evil, and the phrase "he knew" signifies transgression of the commandment. But if this is so, even knowledge of the truth is eating of the tree of life. It is possible for a sober-minded marriage to partake of that tree. We have already observed that marriage may be used rightly or wrongly; and this is the tree of knowledge, if we do not transgress in marriage. What then? Does not the Saviour who heals the soul also heal the body of its passions? But if the flesh were hostile to the soul, he would not have raised an obstacle to the soul by strengthening with good health the hostile flesh. "This I say, brethren, that flesh and blood cannot inherit the kingdom of God nor corruption incorruption." For sin being corruption cannot have fellowship with incorruption which is righteousness. " Are you so foolish?" he says; "having begun in the Spirit are you now to be made perfect by the flesh."
