First Apology 36

But when you hear the words of the prophets spoken as from a person, do not think that they are spoken by the inspired men themselves, but by the divine Word who moves them. For sometimes he speaks as foretelling what is to come to pass, sometimes he speaks as from the person of God, the Master and Father of all, sometimes as from the person of Christ, sometimes as from the person of peoples answering the Lord or his Father; just as can be seen in your own writers, where one is the writer of the whole, but brings in the persons who speak in the dialogue. Not understanding this, the Jews who have the books of the prophets did not recognize Christ even when he came, but they even hate us who say that he has come and show that he was crucified by them, as had been proclaimed beforehand.
