Matthew Henry Commentary Mark 8:27-33

"And Jesus went forth, and his disciples, into the villages of Caesarea Philippi: and on the way he asked his disciples, saying unto them, Who do men say that I am? And they told him, saying, John the Baptist; and others, Elijah; but others, One of the prophets. And he asked them, But who say ye that I am? Peter answereth and saith unto him, Thou art the Christ. And he charged them that they should tell no man of him. And he began to teach them, that the Son of man must suffer many things, and be rejected by the elders, and the chief priests, and the scribes, and be killed, and after three days rise again. And he spake the saying openly. And Peter took him, and began to rebuke him. But he turning about, and seeing his disciples, rebuked Peter, and saith, Get thee behind me, Satan; for thou mindest not the things of God, but the things of men." — Mark 8:27-33 (ASV)

These things are written, that we may believe that Jesus is the Christ, the Son of God. These miracles of our Lord assure us that he was not conquered, but a Conqueror. Now the disciples are convinced that Jesus is the Christ; they can bear to hear of his sufferings, of which Christ here begins to inform them.

He perceives the wrong in our words and actions, of which we ourselves are unaware, and he knows the true nature of our spirit, even when we do not. The wisdom of man is folly when it presumes to limit the Divine counsels. Peter did not rightly understand the nature of Christ's kingdom.
