Matthew 16:11-20

How is it that ye do not perceive that I spake not to you concerning bread? But beware of the leaven of the Pharisees and Sadducees. Then understood they that he bade them not beware of the leaven of bread, but of the teaching of the Pharisees and Sadducees. Now when Jesus came into the parts of Cæsarea Philippi, he asked his disciples, saying, Who do men say that the Son of man is? And they said, Some say John the Baptist; some, Elijah; and others, Jeremiah, or one of the prophets. He saith unto them, But who say ye that I am? 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 Bar-Jonah: for flesh and blood hath not revealed it unto thee, but my Father who is in heaven. And 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. 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. Then charged he the disciples that they should tell no man that he was the Christ.
