Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.

Augustine of Hippo
In App. s. 123: He, who by a touch could heal the severed limbs of others, how much more could He, in His own birth, preserve whole that which He found whole? In this parturition, soundness of the Mother’s body was rather strengthened than weakened, and her virginity rather confirmed than lost. But forasmuch as it was God the Word who was now born in the flesh, He showed Himself to be the Word, in that He preserved His mother’s virginity. For as our word when it is begot does not destroy the mind, so neither does God the Word in choosing His birth destroy the virginity.
Cont. Faust., 12, 45, and 13, 7: Who so mad as to say with Manichaeus, that itis a weak faith not to believe i Christ without a witness; whereas the Apostle says, “How shall they believe on Him of whom they have not heard? Or how shall they hear without a preacher?” For none could suppose that long before Hewas born, He had raised up by magic prophets to prophesy of Him. For if we say to a Gentile, Believe on Christ that He is God, and he should answer, Whence isit that I should believe on Him? we might allege the authority of the Prophets. Should he refuse assent to this, we establish their credit from their having foretold things to come, and those things having truly come to pass. I suppose he could not but know how great persecutions the Christian religion has formerly suffered from the Kings of this world; let him now behold those very Kings submitting to the kingdom of Christ, and all nations serving the same; all which things the Prophets foretold. He then hearing these things out of the Scriptures of the Prophets, and beholding them accomplished throughout the whole earth, would be moved to faith.
