Peter and Paul tangled in Galatians 2:11-16 when Paul saw him clearly in the wrong. In this text show me where Peter repented? In fact Peter dug in his heels and instead compromised the gospel. He even convinced Barbabas.

15 We who are Jews by nature, and not sinners of the Gentiles, 16 knowing that a man is not justified by the works of the law but by faith in Jesus Christ, even we have believed in Christ Jesus, that we might be justified by faith in Christ and not by the works of the law; for by the works of the law no flesh shall be justified.

Peter, though rebuked by Paul, continued to eat with Jews. He was a spiritual coward to the Gentiles. How would Jesus have reacted to that?Peter NEVER repented and was found to be preaching another gospel. In all of the Bible show me where rebellious Peter ever repented of this ? A fit leader for the RCC who also never repent. Instead they cover it up.
