"Paul writes, “11 When Peter came to Antioch, I opposed him to his face, because he was clearly in the wrong."
The last time I checked, Jesus made the Peter the leader of the Church.
As far as Paul's letters being considered scripture, does that make him an apostle?
Also, are all of Paul's letters included in the Bible? The Church has a bad history of not including everything in the Bible.[/QUOTE]
So, yes, they clashed, but it was because Peter was acting like a bigot. Peter was sinning with the way he acted, and Paul rebuked him for it. Peter changed his ways, proving that he acknowledged the fact he was wrong.
It's no different than when "Jesus made Peter the leader of the Church"(I'll get to that in a minute) in Matthew 16. Just a few verses later, Peter tells Jesus he surely won't suffer and die, and Jesus rebukes him, saying "Behind me Satan!". Peter screwed up, not worrying about what God's will was, more focused on what he thought should happen.
If Paul never stood up to Peter, you would just take offense to the fact that Peter was a bigot. It's better for Paul to have corrected Peter.
As for Peter being the leader of the church, that is strictly the Catholic interpretation of Matthew 16. The Protestant view is that the "rock" Jesus says he will build his church on refers to Peter's confession that Jesus is the Son of God.
EDIT:I should say that is one Protestant view. We do not hold Peter as any sort of Pope or leader. He preached the Sermon in Acts 2 at Pentecost that started the movement of Christianity, but I do not believe Jesus gave Peter more authority than anyone else.
Even if Peter was the leader of the Early Church, that doesn't mean he can't screw up, which Peter did numerous times. The thing is, Peter corrected himself after he made mistakes, such as when he withdrew from the Gentiles to please the circumsized crowd(which is the basis for the disagreement in Galatians 2 that you quoted). Paul rebuked him, Peter changed his ways back to more accurately represent the Gospel of Christ.
Isn't that what this entire thread is about? The Catholic Priests made a HUGE mistake when they molested children, but the Catholic Church made an even BIGGER mistake by trying to cover it up, and now it has affected the Papal seat. Had Pope Benedict XVI, the current pope, corrected these problems at the time, it hopefully would not be an issue now like it is.
Bottom line:
Catholic Church-more concerned with their own image, not God's will
Peter-more concerned with God's will than his own image.
As for all Paul's letters being considered Scripture, every letter that we have found by Paul, I believe they are part of the Canon. There are instances where we don't have certain letters, so they are not in the Bible. For example, 1&2 Corinthians are actually, we believe, the 2nd and 4th letters Paul wrote to Corinth, but we have never found the 1st and 3rd. We don't call them 1 Corinthians and 2 Corinthians because they are the first and second overall, just first and second that we currently have.
Canon was established by the Council of Carthage in the 4th Century.
The Apocrypha was not added by the Catholic Church until 1546 at the Council of Trent, which was after Martin Luther had already broken away(1517).
