Peter Cultural  

1. Chief among the Twelve Apostles of Jesus, he was a fisherman, originally named Simon (and often called Simon Peter). Jesus gave him the name Rock, of which “Peter” is a translation. Peter showed great faith but also exhibited great failings (see Get thee behind me, Satan). In the frightening hours before the Crucifixion, Peter three times denied being a follower of Jesus, just as Jesus had predicted he would. Nevertheless, Peter went on to become the leader of the early Christians (see also Christian) (see Pentecost), thus fulfilling another prophecy of Jesus, who had said of Peter, “Upon this rock I will build my church …. And I will give unto thee the keys of the kingdom of heaven.”

Peter is often depicted holding keys. Roman Catholics maintain a number of traditions about Peter: that he was the first of the popes, for example, and that he was martyred at Rome by being crucified upside down, because he refused to be crucified as Jesus had been.
