8. Then Jesus, knowing this, said: "Why do you consider within yourselves, O little in faith, that it is because you have no bread?
9. Do you not yet understand, nor remember, the five loaves among the five thousand men, and how many containers you took up?
10. Or the seven loaves among the four thousand men, and how many baskets you took up?
11. Why do you not understand that it was not because of bread that I said to you: Beware of the leaven of the Pharisees and the Sadducees?"
12. Then they understood that he was not saying that they should beware of the leaven of bread, but of the doctrine of the Pharisees and the Sadducees.
13. Then Jesus went into parts of Caesarea Philippi. And he questioned his disciples, saying, "Who do men say that the Son of man is?"
14. And they said, "Some say John the Baptist, and others say Elijah, still others say Jeremiah or one of the prophets."
15. Jesus said to them, "But who do you say that I am?"
16. Simon Peter responded by saying, "You are the Christ, the Son of the living God."
17. And in response, Jesus said to him: "Blessed are you, Simon son of Jonah. For flesh and blood has not revealed this to you, but my Father, who is in heaven.
18. And I say to you, that you are Peter, and upon this rock I will build my Church, and the gates of Hell shall not prevail against it.
19. And I will give you the keys of the kingdom of heaven. And whatever you shall bind on earth shall be bound, even in heaven. And whatever you shall release on earth shall be released, even in heaven."
