This event at Caesarea Philippi revealed Jesus as the promised Messiah.
The story is a conversation between Jesus and his disciples in which he openly questions them about his identity.
Peter, Jesus' closest disciple, was the one to speak up when directly asked “Who do you say that I am?” Peter’s response shows a clear knowledge of Jesus’ identity, “You are the Messiah, the Son of the living God.”
Jesus then ordered the disciples not to tell anyone about what happened. This is an example of the messianic secret.
Peter plays a key role in this story. We know that he became the first Pope, so this event would have given Jesus confidence that Peter was following him for the right reasons. Jesus calls him the rock on which he will build his church. Peter’s name was changed from Simon as the name Peter means ‘rock’.
