Simon Peter

Simon Peter was one of the twelve Apostles of Jesus. He got the name "Peter" when Jesus said he'd build his church on this rock. ("Peter" comes from the Greek for "rock.") Paul sometimes called him "Cephas," which means the same thing in Aramaic (I think). Catholics believe that Peter was the first Pope.

Peter, along with James and John, witnessed some events that were not seen by the other apostles, including the Transfiguration.
