Matthew 16:13-18

13Now when Jesus came into the parts of Cæsarea Philippi, he asked his disciples, saying, Who do men say that the Son of man is? 14And they said, Some say John the Baptist; some, Elijah; and others, Jeremiah, or one of the prophets. 15He saith unto them, But who say ye that I am? 16And Simon Peter answered and said, Thou art the Christ, the Son of the living God. 17And Jesus answered and said unto him, Blessed art thou, Simon Bar-Jonah: for flesh and blood hath not revealed it unto thee, but my Father who is in heaven. 18And I also say unto thee, that thou art Peter, and upon this rock I will build my church; and the gates of Hades shall not prevail against it.
