Changes

During Jesus' ministry he asked his disciples who they believed him to be. Simon Peter answered, "You are the Christ, the Son of the living God". Jesus responded that, "On this rock I will build my church". Because Peter (Petros) in Greek means rock, and Jesus uses the word rock (petra), Roman Catholic doctrine teaches that Peter is the rock on whom Jesus builds his church. From this, the authority of the pope is established, who is considered Peter's replacement now on earth. Protestant interpretation is very different and is that Jesus is using a play on words to claim that he will build his church on the rock or foundation that he is "the Christ, the Son of the living God"
