I Fought The Law

With the Jews, Paul abstained from what was forbidden. With the Gentiles he exercised his freedom. In this passage, it's not so black and white as Paul is dealing with converted believers. Similar contextualization is not necessary, in fact it can be confusing. The issue for Paul with Peter is not one of contextualization, rather hypocrisy. Peter's offense here is weakness with the religious Judaizers. It's not the action that is the problem, but the end. What it communicates in this context is that Jesus does not justify us alone. And this is what happens when legalists push agendas in the church and you want their approval.
