Paul was a pharisee of the pharisees...it took him 14 years to understand the church of one body, Jew and Gentile...it wasn't an easy doctrinal issue for Peter to learn quickly.
But somehow Peter violated Jewish law and tradition by living after the manner of Gentiles.
His down fall wasn't living after the manner of Gentiles, it was going back to the law and traditions.
Or as I suggested, the Lord wasn't yet ready to reveal this to them because he wasn't yet ready to give his spirit to non-jews until this time. So he allowed them to continue in their sinful and unscriptural attitudes toward gentiles.

Jewish NON-SCRIPTURAL law and NON-SCRIPTURAL tradition.
Act 10:28 And he said unto them, Ye know how that it is an unlawful thing for a man that is a Jew to keep company, or come unto one of another nation; but God hath showed me that I should not call any man common or unclean.
Again, this wasn't a scriptural law that Peter is referring to.

Yep, going back to non-scriptural laws and traditions.
