Simon was a fisherman. His brother Andrew said to him, "I have met Jesus. Come and see Him." Simon loved Jesus. Jesus gave him the name Peter, which means " rock." Jesus picked eleven other Apostles and said to them, "Follow Me, and I will make you fishers of men." He meant that He would send them to do His work of bringing people to God. The Apostles gave up their homes to follow Jesus.
One day Jesus said to them, "Who do you think I am?" Peter answered, "You are Christ, the Son of God."
Our Lord was pleased and said, "You are Peter, a rock, and I will build My church upon you. I will give you the keys of the kingdom of heaven." This is the power to help people get to heaven.
After His Resurrection, Jesus asked Peter three times, "Peter, do you love Me?" Three times Peter answered, "Lord, You know that I love You." And Jesus said to him, "Feed My lambs, feed My sheep." In this way Jesus made it clear that Peter was to be the first pope. Peter was crucified in Rome, head downward, because he said he was not worthy to die the same way as Jesus.
