"But when Peter came to Antioch, I opposed him to his face — because he was clearly in the wrong.
Here's what happened: before certain men arrived from James, Peter was eating with the Gentile believers. No hesitation. But when those men showed up — people from the circumcision party — he pulled back. He separated himself. He was afraid of what they'd think.
And the rest of the Jewish believers followed his lead, acting just as hypocritically — so that even Barnabas got swept up in it.
When I saw that they weren't walking in line with the truth of the gospel, I said to Peter in front of everyone: 'You're Jewish, but you've been living like a Gentile. So how can you now turn around and pressure Gentiles to live like Jews?'"
