21. And what is virginal chastity but purity free
from stain? And whom can we judge to be its author but the
immaculate Son of God, Whose flesh saw no corruption, Whose Godhead
experienced no infection? Consider, then, how great are the
merits of virginity. Christ was before the Virgin, Christ was of
the Virgin. Begotten indeed of the Father before the ages, but
born of the Virgin for the ages. The former was of His own
nature, the latter is for our benefit. The former always was, the
latter He willed.
