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.
