On the Incarnation, Book 7
Without Genealogy
How does he say that the Lord was “without genealogy,” when the Gospel of the evangelist Matthew begins with the Savior’s genealogy, saying, “The book of the generations of Jesus Christ, the son of David, the son of Abraham”? So according to the evangelist he has a genealogy, and according to the apostle he has not. According to the evangelist he has one on his mother’s side; according to the apostle he has none, as he springs from the Father. And so the apostle rightly says, “Without father, without mother, without genealogy.” Where he lays down that he was begotten without mother, there he also records that he was without genealogy. In this way the writings of the evangelist and of the apostle agree about both of the Lord’s births. According to the evangelist, he has a genealogy “without father,” when he is born in the flesh. According to the apostle, the Lord has none when he is begotten in his divine nature “without mother,” as Isaiah says: “But who will declare his generation?”
