In todays episode we see Paul confront Peter for his hypocrisy as he withdraws from the very Gentiles he would normally spend time with only to snub them to try to save face in front of legalistic Jewish Christians. Paul was having none of this betrayal because he knew how wrong it was and how damaging this behavior and theology could be to the entire message of the cross. He stood in this awkward, uncomfortable conflict because he loved everyone involved so much that he was willing to wound them so they would come back to truth; truth that would keep ALL of us in freedom rather than bound to rules.
