Ambrose of Milan

The Lord in every thing so humbled Himself to obedience, that He did not despise even the office of a reader, as it follows, And he rose up to read, and there was delivered unto him the book, &c. He received the book indeed, that He might shew Himself to be the same who spoke in the Prophets, and that He might stop the blasphemies of the wicked, who say that there is one God of the Old Testament, another of the New; or who say that Christ had His beginning from a virgin. For how did He begin from a virgin, who spoke before that virgin was?
