St Luke 9:18-22

And it came to pass, as he was alone praying, his disciples also were with him: and he asked them, saying: Whom do the people say that I am? But they answered, and said: John the Baptist; but some say Elias; and others say that one of the former prophets is risen again. And he said to them: But whom do you say that I am? Simon Peter answering, said: The Christ of God. But he strictly charging them, commanded they should tell this to no man. Saying: The Son of man must suffer many things, and be rejected by the ancients and chief priests and scribes, and be killed, and the third day rise again.
