Matthew 22:44

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.

That He says, Sit thou on my right hand, is not to be taken as though God had a body, and either a right hand or a left hand; but to sit on the right hand of God is to abide in the honour and equality of the Father's majesty. But till is used for indefinite time, that the meaning be, Sit Thou for ever, and for ever hold thine enemies beneath thy feet.

Therefore, (as they further hold, ) those other words, "Before the morning star did I beget thee from the womb," are applicable to Hezekiah, and to the birth of Hezekiah.

And that they may not say, that it was in flattery he so called Him, and that this was a human judgment, see what He saith, "How then doth David in spirit call Him Lord?" See how submissively He introduces the sentence and judgment concerning Himself. First, He had said, "What think ye? Whose Son is He?" so by a question to bring them to an answer. Then since they said, "the Son of David," He said not, "And yet David saith these things," but again in this order of a question, "How then doth David in spirit call Him Lord?" in order that the sayings might not give offense to them. Wherefore neither did He say, What think ye of me, but of Christ. For this reason the apostles also reasoned submissively, saying, "Let us speak freely of the Patriarch David, that he is both dead and buried." And He Himself too in like manner for this cause introduces the doctrine in the way of question and inference, saying, "How then doth David in spirit call Him Lord, saying, The Lord said unto my Lord, Sit Thou on my right hand, until I make Thy foes Thy footstool;" and again, "If David then call Him Lord, how is He then his Son," not taking away the fact that He is his Son, away with the thought; for He would not then have reproved Peter for this, but to correct their secret thoughts. So that when He saith, "How is He his Son?" He meaneth this, not so as ye say. For they said, that He is Son only, and not also Lord. And this after the testimony, and then submissively, "If David then call Him Lord, how is He his Son?"

Then since He had answered, He asks also in turn, "What think ye of Christ, whose Son is He? They say unto Him, The Son of David." See after how many miracles, after how many signs, after how many questions, after how great a display of His unanimity with the Father, as well in words, as in deeds; after having praised this man that said, that there is one God, He asks the question, that they may not be able to say, that He did miracles indeed, yet was an adversary to the law, and a foe to God. Therefore, after so many things, He asks these questions, secretly leading them on to confess Him also to be God. And the disciples He asked first what the others say, and then themselves; but these not so; for surely they would have said a deceiver, and a wicked one, as speaking all things without fear. So for this cause He inquires for the opinion of these men themselves. For since He was now about to go on to His passion, He sets forth the prophecy that plainly proclaims Him to be Lord; and not as having come to do this without occasion, nor as having made this His aim, but from a reasonable cause. For having asked them first, since they answered not the truth concerning Him (for they said He was a mere man), to overthrow their mistaken opinion, He thus introduces David proclaiming His Godhead.
