Reply to Faustus the Manichaean

³ For our part, while no one can alter our conviction that the Son of God comes from God, we might indulge a credulous disposition, to the extent of admitting the fiction, that Jesus became the Son of God at Jordan, but not that the Son of God was born of a woman. Then, again, the son said to have been born of Mary cannot properly be called the son of David, unless it is ascertained that he was begotten by Joseph. You say he was not, and therefore you must allow him not to have been the son of David, even though he were the son of Mary. The genealogy proceeds in the line of Hebrew fathers from Abraham to David, and from David to Joseph; and as we are told that Joseph was not the real father of Jesus, Jesus cannot be said to be the son of David. To begin with calling Jesus the son of David, and then to go on to tell of his being born of Mary before the consummation of her marriage with Joseph, is pure madness. And if the son of Mary cannot be called the son of David, on account of his not being the son of Joseph, still less can the name be given to the Son of God.
