33 And why should I tell how great is the grace of virginity, which was found worthy to be chosen by Christ, that it might be even the bodily temple of God, in which as we read the fullness of the Godhead dwelt bodily. A Virgin conceived the Salvation of the world, a Virgin brought forth the life of all. Virginity then ought not to be left to itself, seeing that it benefited all in Christ. A Virgin bore Him Whom this world cannot contain or support. And when He was born from His mother's womb, He yet preserved the fence of her chastity and the inviolate seal of her virginity. And so Christ found in the Virgin that which He willed to make His own, that which the Lord of all might take to Himself. Further, our flesh was cast out of Paradise by a man and woman and was joined to God through a Virgin.
