Jerome
Catena Aurea · Matthäusevangelium 22
While the Pharisees were gathered together, Jesus asked them, Saying, What think ye of Christ? whose son is he? They say unto him, The Son of David. He saith unto them, How then doth David in spirit call him Lord, saying, The Lord saith unto my Lord, Sit thou on my right hand, till I make thine enemies thy footstool? If David then call him Lord, how is he his son? And no man was able to answer him a word, neither durst any man from that day forth ask him any more questions.
This passage is out of the 109th Psalm. Christ is therefore called David’s Lord, not in respect of His descent from him, but in respect of His eternal generation from the Father, wherein He was before His fleshly Father. And he calls Him Lord, not by a mere chance, nor of his own thought, but by the Holy Spirit.
