Matthew 16:15

12 Then they saw that it was not the leaven of bread which he had in mind, but the teaching of the Pharisees and Sadducees.

13 Now when Jesus had come into the parts of Caesarea Philippi, he said, questioning his disciples, Who do men say that the Son of man is?

14 And they said, Some say, John the Baptist; some, Elijah; and others, Jeremiah, or one of the prophets.

15 He says to them, But who do you say that I am?

16 And Simon Peter made answer and said, You are the Christ, the Son of the living God.

17 And Jesus made answer and said to him, A blessing on you, Simon Bar-jonah: because this knowledge has not come to you from flesh and blood, but from my Father in heaven.

18 And I say to you that you are Peter, and on this rock will my church be based, and the doors of hell will not overcome it.
