“The evangelist Luke, when giving the genealogy according to the flesh of our God and Saviour Jesus Christ, and stepping up from the last to the first, begins with Joseph, saying that he was ‘the son of Heli, which was the son of Matthat,’ and so by ascending brings his enumeration up to Adam; but when he has come to the top and said, that Seth ‘was the son of Adam, which was the son of God,’ then he stops this process. As, then, he has said that Adam was the son of God, we will ask these men, ‘But God, who is He the son of?’ Is it not obvious to every one’s intelligence that God is the son of no one? But to be the son of no one is to be without a cause, plainly; and to be without a cause is to be ungenerate. Now in the case of men, the being son of somebody is not the essence; no more, in the case of the Deity Who rules the world, is it possible to say that the being ungenerate is the essence.”
