He was the rock. He was a foundational leader of the church. But he wasn’t above being called out when he was wrong.
Peter was eating with Gentiles (Galatians 2:11-14). At first, that doesn’t seem like much to me because, well, I’m a Gentile. But Peter had spent his entire life living by the strict dietary restrictions we find in the Old Testament. Things changed in Acts 10 when God gave Peter a vision of several unclean animals in a sheet and said every hunter’s favorite Bible verse, “Rise, Peter; kill and eat” (Acts 10:9-13). My friend calls this the first pig in a blanket.
So a little while later Peter finds himself doing the unthinkable. Eating with Gentiles. And I’m sure that he loved the taste of those pulled pork sandwiches and catfish. Something like that. You get the picture.
But then some of the Jewish elites showed up. And when they did, Peter was caught. Should he stay at the Gentile table at that proverbial New Testament high school cafeteria or should he go back to sit with his old friends. Peter went back to his old friends. But it was more than just nostalgia that pulled Peter away from the Gentile table. It was fear.
The message was clear from Peter. “Gentiles, I’m with you and this new covenant until my people show up and then it’s back to the old way. It’s been real.”
Thankfully, Paul was there and his message to Peter was even clearer. He opposed Peter publicly.
 But when I saw that their conduct was not in step with the truth of the gospel, I said to Cephas (Peter) before them all, “If you, though a Jew, llive like a Gentile and not like a Jew, how can you force the Gentiles to live like Jews?” Galatians 2:14 (ESV)
Here’s a translation of what Paul said. “Peter, why do you hold the Gentiles to standards that you can’t even keep?”
This was a pivotal time for the church. Peter was influential and his hypocrisy could have led the young movement back into the self-righteousness that they had been delivered from. Paul’s open confrontation could have caused a major split between he and Peter and, by extension, the church as a whole.
But it didn’t. And for that, we have Peter to thank.
Paul doesn’t tell us how Peter responded to being held accountable by the former murderer turned missionary to the Gentiles. Did he storm out of the room? Did he post a vague Facebook status in all caps about people needing to, “Mind their own business?”
One of Peter’s letters, written years after this incident gives us a good clue.
 And count the patience of our Lord as salvation, just as our beloved brother Paul also wrote to you according to the wisdom given him,  as he does in all his letters when he speaks in them of these matters. There are some things in them that are hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other Scriptures. 2 Peter 3:15-16 (ESV)
Peter refers to Paul, the one who rebuked him years earlier, as, “Our beloved brother” and speaks of him having God-given wisdom. He acknowledges that Paul’s words can be hard to understand and easy to to distort but he finishes with a very important assessment of Paul’s letters. They are part of the Scriptures. That is, they carry the authority of God’s word.
We need Paul’s in our life. We need people who care enough about us and the gospel to lovingly correct us when we are wrong. The very worst thing that could happen to the church or to you as an individual is for everyone around you to, “Mind their own business.”
And when those people do step in to lovingly hold you accountable, it does no good unless you respond like Peter and accept their authority and wisdom. Use their words as an opportunity to examine your life.
My growth in my walk with Christ has little to nothing to do with my own individual perseverance. It has much more to do with God putting people in my life who love me too much to, “Mind their own business.” I pray that he does the same for you.
