Jesus went to the territory near the town of Caesarea Philippi, where he asked his disciples, "Who do people say the Son of Man is?"
"Some say John the Baptist," they answered. "Others say Elijah, while others say Jeremiah or some other prophet."
"What about you?" he asked them. "Who do you say I am?"
Simon Peter answered, "You are the Messiah, the Son of the living God."
"Good for you, Simon son of John!" answered Jesus. "For this truth did not come to you from any human being, but it was given to you directly by my Father in heaven.
And so I tell you, Peter: you are a rock, and on this rock foundation I will build my church, and not even death will ever be able to overcome it.
I will give you the keys of the Kingdom of heaven; what you prohibit on earth will be prohibited in heaven, and what you permit on earth will be permitted in heaven."
Then Jesus ordered his disciples not to tell anyone that he was the Messiah.
From that time on Jesus began to say plainly to his disciples, "I must go to Jerusalem and suffer much from the elders, the chief priests, and the teachers of the Law. I will be put to death, but three days later I will be raised to life."
Peter took him aside and began to rebuke him. "God forbid it, Lord!" he said. "That must never happen to you!"
Jesus turned around and said to Peter, "Get away from me, Satan! You are an obstacle in my way, because these thoughts of yours don't come from God, but from human nature."
Then Jesus said to his disciples, "If any of you want to come with me, you must forget yourself, carry your cross, and follow me.
For if you want to save your own life, you will lose it; but if you lose your life for my sake, you will find it.
Will you gain anything if you win the whole world but lose your life? Of course not! There is nothing you can give to regain your life.
For the Son of Man is about to come in the glory of his Father with his angels, and then he will reward each one according to his deeds.
I assure you that there are some here who will not die until they have seen the Son of Man come as King."
Six days later Jesus took with him Peter and the brothers James and John and led them up a high mountain where they were alone.
As they looked on, a change came over Jesus: his face was shining like the sun, and his clothes were dazzling white.
Then the three disciples saw Moses and Elijah talking with Jesus.
So Peter spoke up and said to Jesus, "Lord, how good it is that we are here! If you wish, I will make three tents here, one for you, one for Moses, and one for Elijah."
While he was talking, a shining cloud came over them, and a voice from the cloud said, "This is my own dear Son, with whom I am pleased - listen to him!"
When the disciples heard the voice, they were so terrified that they threw themselves face downward on the ground.
Jesus came to them and touched them. "Get up," he said. "Don't be afraid!"
So they looked up and saw no one there but Jesus.
As they came down the mountain, Jesus ordered them, "Don't tell anyone about this vision you have seen until the Son of Man has been raised from death."
Then the disciples asked Jesus, "Why do the teachers of the Law say that Elijah has to come first?"
"Elijah is indeed coming first," answered Jesus, "and he will get everything ready.
But I tell you that Elijah has already come and people did not recognize him, but treated him just as they pleased. In the same way they will also mistreat the Son of Man."
Then the disciples understood that he was talking to them about John the Baptist.
When they returned to the crowd, a man came to Jesus, knelt before him,
and said, "Sir, have mercy on my son! He is an epileptic and has such terrible attacks that he often falls in the fire or into water.
I brought him to your disciples, but they could not heal him."
Jesus answered, "How unbelieving and wrong you people are! How long must I stay with you? How long do I have to put up with you? Bring the boy here to me!"
Jesus gave a command to the demon, and it went out of the boy, and at that very moment he was healed.
Then the disciples came to Jesus in private and asked him, "Why couldn't we drive the demon out?"
"It was because you do not have enough faith," answered Jesus. "I assure you that if you have faith as big as a mustard seed, you can say to this hill, "Go from here to there!' and it will go. You could do anything!"
