27 And Jesus went out, with his disciples, into the little towns round Caesarea Philippi; and on the way he put a question to his disciples, saying, Who do men say that I am? 28 And they made answer, John the Baptist; and others, Elijah; but others, One of the prophets. 29 And he said to them, But who do you say I am? Peter said in answer, You are the Christ. 30 And he put them under orders not to say this of him to anyone.
31 And teaching them, he said that the Son of man would have to undergo much, and be hated by those in authority, and the chief priests, and the scribes, and be put to death, and after three days come back from the dead. 32 And he said this openly. And Peter took him, and was protesting. 33 But he, turning about, and seeing his disciples, said sharply to Peter, Get out of my way, Satan: for your mind is not on the things of God, but on the things of men.

Commentary on Mark 8:27-33
(Read Mark 8:27-33)
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 may bear to hear of his sufferings, of which Christ here begins to give them notice. He sees that amiss in what we say and do, of which we ourselves are not aware, and knows what manner of spirit we are of, when we ourselves do not. The wisdom of man is folly, when it pretends to limit the Divine counsels. Peter did not rightly understand the nature of Christ's kingdom.
