MAT 16:13 ¶ Now when Jesus came into the district of Caesarea Philippi, He was asking His disciples, "Who do people say that the Son of Man is?"
MAT 16:14 And they said, "Some say John the Baptist; and others, Elijah; but still others, Jeremiah, or one of the prophets."
MAT 16:15 He said to them, "But who do you say that I am?"
MAT 16:16 Simon Peter answered, "You are the Christ, the Son of the living God."
MAT 16:17 And Jesus said to him, "Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven.
MAT 16:18 "I also say to you that you are Peter, and upon this rock I will build My church; and the gates of Hades will not overpower it.
MAT 16:19 "I will give you the keys of the kingdom of heaven; and whatever you bind on earth shall have been bound in heaven, and whatever you loose on earth shall have been loosed in heaven."
MAT 18:1 At that time the disciples came to Jesus and said, "Who then is greatest in the kingdom of heaven?"
MAT 18:15 ¶ "If your brother sins, go and show him his fault in private; if he listens to you, you have won your brother.
MAT 18:16 "But if he does not listen to you, take one or two more with you, so that by the mouth of two or three witnesses every fact may be confirmed.
MAT 18:17 "If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.
MAT 18:18 "Truly I say to you, whatever you bind on earth shall have been bound in heaven; and whatever you loose on earth shall have been loosed in heaven.
MAT 18:19 ¶ "Again I say to you, that if two of you agree on earth about anything that they may ask, it shall be done for them by My Father who is in heaven.
MAT 18:20 "For where two or three have gathered together in My name, I am there in their midst."
GAL 2:11 ¶ But when Cephas came to Antioch, I opposed him to his face, because he stood condemned.
GAL 2:12 For prior to the coming of certain men from James, he used to eat with the Gentiles; but when they came, he began to withdraw and hold himself aloof, fearing the party of the circumcision.
GAL 2:13 The rest of the Jews joined him in hypocrisy, with the result that even Barnabas was carried away by their hypocrisy.
GAL 2:14 But when I saw that they were not straightforward about the truth of the gospel, I said to Cephas in the presence of all, "If you, being a Jew, live like the Gentiles and not like the Jews, how is it that you compel the Gentiles to live like Jews?
Although it is claimed by the Catholic Church that Peter was endowed with special authority that no other apostle had, the Scriptures above make it clear that all the apostles were given authority. Although they were inspired, it did not make them incapable of sinning for even Peter was rebuked by the apostle Paul. He did not ever claim to be infallible like the Pope does today
