When Jesus and his disciples came to the area of Caesarea Philippi, a town north of the region of Galilee, he asked his disciples privately, “Who are people in the crowds saying I am?” They replied “Some say you are John the Baptist. Others think you are Elijah, and yet others think you are Jeremiah or one of the other prophets.”
Jesus faced them and said “But as for you, who do you say I am?” Simon answered him saying “You are the Christ, the Messiah, the Son of the living God!”

Jesus responded “Simon, son of Jonah, God has blessed you with this knowledge because you didn’t learn this from a person but directly from God!” Jesus continued, saying “Your name is now Peter, because you are a rock, and upon you I will build my living church, and the gates of death will not overpower it. I will give you the keys of the kingdom of heaven. Whatever you join together on earth will be joined together in heaven, and whatever you separate on earth will be separated in heaven.”
Then he gave them very strict orders not to tell anyone that he was the Messiah.
