Peter's Confession of Christ Matthew 16:13 When Jesus came to the region of Caesarea Philippi, he asked his disciples, "Who do people say the Son of Man is?"
14They replied, "Some say John the Baptist; others say Elijah; and still others, Jeremiah or one of the prophets."
15"But what about you?" he asked. "Who do you say I am?"
16Simon Peter answered, "You are the Christ, the Son of the living God."
17Jesus replied, "Blessed are you, Simon son of Jonah, for this was not revealed to you by man, but by my Father in heaven. 18And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. 19I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven." 20Then he warned his disciples not to tell anyone that he was the Christ.
21From that time on Jesus began to explain to his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, chief priests and teachers of the law, and that he must be killed and on the third day be raised to life.
22Peter took him aside and began to rebuke him. "Never, Lord!" he said. "This shall never happen to you!"
23Jesus turned and said to Peter, "Get behind me, Satan! You are a stumbling block to me; you do not have in mind the things of God, but the things of men."
That's quite strong rebuke to the man who Catholics claim was just appointed the position of being Christ's representative on earth, the first pope, the leader of Christ's church, with the power to forgive sins and hold the keys to heaven and hell.
If one can defend St. Paul as a man redeemed, then one can do the same for St. Peter.
“Saul, Saul, why persecutest thou Me?” —and Saul went on to become a great apostle.
St. Peter had not yet eperienced the redemption of the Cross when those words were spoken to him.
And so it is with all of us who have once been “no people, but now are God’s people, ..once had not received mercy but now have received mercy” (!Peter 2:10)
A very strong rebuke. Jesus interacted with Peter almost to the exclusion of the other Apostles, including the Apostles that He loved. He praised, He taught and He rebuked. You bet. And we see in Acts that the teachings of Jesus had acted greatly upon Peter, although being human, he did have to be corrected by Paul once.
