Context: Jesus, having taught the multitudes and displayed for them His divine power by miracles of healing and of feeding four thousand by the Sea of Galilee, moves up to Caesarea Phillippi with His disciples, concentrating upon making the message of His kingdom clear to them in preparation for the time when they must carry on the work of the kingdom after His ascension. Jesus, asking the disciples who men think He is, is told that He is considered to be a prophet, perhaps John the Baptist, Elias, or Jeremias. The Master then asks who the disciples believe He is:
And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
And 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.
And 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.
And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
