If Peter or anyone else starts by pulling down the wall between Jew and Gentile (as Peter had indeed done: “You’re a Jew, but you’ve been living like a Gentile”) and then decides to rebuild it, all he is doing is pointing the finger back at himself. He is admitting that he was wrong to “live like a Gentile,” and he is invoking the law, which will simply remind him that he is in any case a lawbreaker.
