But they said: Some John the Baptist, and other some Elias, and others Jeremias, or one of the prophets.
Jesus saith to them: But whom do you say that I am?
Simon Peter answered and said: Thou art Christ, the Son of the living God.

And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it.
