Galatians 2:8-12

(for He who was at work for Peter in his apostleship to the circumcised was at work for me also to the Gentiles),

and recognizing the grace that had been given to me, James and Cephas and John, who were reputed to be pillars, gave to me and Barnabas the right hand of fellowship, so that we might go to the Gentiles, and they to the circumcised.

They only asked us to remember the poor—the very thing I also was eager to do. Peter (Cephas) Opposed by Paul

But when Cephas came to Antioch, I opposed him to his face, because he stood condemned.

For prior to the coming of some men from James, he used to eat with the Gentiles; but when they came, he began to withdraw and separate himself, fearing those from the circumcision.
