From Scripture

                              Matthew 16:13-19
                              The Rock for ages

                              The events in this passage lay the foundations for the Catholic Church.  Jesus first asked his disciples who people say he was.  Their answers named the ancient prophets reincarnated.  Then Jesus asked, "Who do you say that I am?"   Simon Peter answered for the group and identified Jesus as the Son of God.  This highlighted Peter's role as spokesperson for the disciples.
                              Jesus pointed out that it was only by inspiration from the Father that Peter was able to recognize the truth about Jesus.  ("No one but the Son knows the Son,"  Matthew 11:27.)  Divine inspiration would lead Peter to speak and act in truth as head of Christ's Church.  The Holy Spirit guides the pope to speak and act in truth today.
                              The Church has to last until the end of time.  When Jesus changed Simon"s name to "Peter," he signaled that he was building his Church on "rock," a solid foundation upon which a wise man will build his home  (Matthew 7:24).
