14And they said, Some say that thou art John the Baptist: some, Elias; and others, Jeremias, or one of the prophets. 15He saith unto them, But whom 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 Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven. 18And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
~ Matthew 16:14-18
