In a dialogue between Jesus and his disciples . Jesus asks, "Who do people say that the Son of Man is?" The disciples give various answers. When he asks, "Who do you say that I am?" Simon Peter answers, "You are the Messiah, the Son of the living God." Jesus then declares:
Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven. And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.
His apostolic activity in Judea and the neighboring districts after the resurrection of Jesus is recorded chiefly in Acts. After the ascension, he ,undismayed by the threats of the Sanhedrin at Jerusalem, preached and worked in Samaria performing many miracles. When he returned to Jerusalem, he was imprisoned under Herod Agrippa after the death of James. He escaped, left the city and he seems to have taken up his residence there after Herod's death.
