Luke 20:44

Christ indeed is both the Lord and Servant of David. He is Servant, according to the flesh, being a descendant of David; and he is Lord, according to the spirit, being Lord of all. (St. John Chrysostom) --- We hear in our times of a new sect of Pharisees, who neither believed that Christ is the true Son of God, nor that he is God born of a pure virgin. To such we object this question: How is he the Son of David, and his Lord? Not by human, but by divine dominion. (St. Cyril) --- He has two natures: the nature of man, according to which, David was his father; and the nature of God, according to which, he was Son of God, and Lord of David. Thus is the difficulty solved.
