John Chrysostom
He first asked His disciples what others said of Christ, and then what they themselves said; but not so to these. For they would have said that He was a deceiver, and wicked. They thought that Christ was to be mere man, and therefore they say unto Him, The Son of David. To reprove this, He brings forward the Prophet, witnessing His dominion, proper Sonship, and His joint honour with His Father.
But He rests not with this, but that they may fear, He adds, Till I make thine enemies thy footstool; that at least by terror He might gain them.
This conclusion He put to their questionings, as final, and sufficient to stop their mouth. Henceforward accordingly they held their peace, not by their own good-will, but from not having aught to say.
The Jews tempted Christ, supposing Him to be mere man; had they believed Him to be the Son of God, they would not have tempted Him. Christ therefore, willing to shew that He knew the treachery of their hearts, and that He was God, yet would not declare this truth to them plainly, that they might not take occasion thence to charge Him with blasphemy, and yet would not totally conceal this truth; because to that end had He come that He should preach the truth; He therefore puts a question to them, such as should declare to them who He was; What think ye of Christ? whose Son is He?
I suppose that He formed this question, not only against the Pharisees, but also against the heretics; for according to the flesh He was truly David’s Son, but his Lord according to His Godhead.
