"Peter was not teaching false doctrine. He was teaching one thing and acting another. He was a hypocrite, not a false teacher."
The comment on Peter was in regard to Enoch's humility in admitting that he was wrong. Peter was rebuked, publicly, and responded in a way that could only have been directed by the Spirit, especially when you consider Pater's nature. Just as an aside Krispy, it was a doctrinal matter, but this is not what this thread is about.
Gal 2:14 But when I saw that they did not walk uprightly with the truth of the gospel, I said to Peter before all, If you, being a Jew, live as a Gentile, and not as the Jews, why do you compel the nations to judaize?
In the context of Galatians 2 and especially Gal 2:4 , this was certainly a doctrinal matter, enough to call a council over it, the first council ever. Yet again, and back to the original posters question, there is a difference between doctrinal differences, interpretations and a false prophet. One can be wrong doctrinally and not be a false prophet, which is what Enoch so humbly alluded too................brother Frank
