<p>1:2 <em>And all the brothers that are with me, to the churches of Galatia</em>- Those <em>sun</em> Paul may refer to brothers who supported Paul's position on the Law, which was going to be the burden of this letter. It was Paul who was the inspired author but he is making the point that there were other brethren who agreed with his position. The churches of Galatia could have referred to quite a few of the congregations Paul is recorded as founding in Acts; because he sees his responsibilities as being to his own converts and his letters are generally addressed to those he has converted. These groups were largely Gentiles. I have noted elsewhere, especially on Titus, Corinthians and 1 Timothy, that Gentile converts often brought with them immoral practices. Yet they became attracted to Judaism because their religious conscience could be more easily salved by obedience to a set of ritual requirements, and their more fundamental moral habits would then be left unquestioned. Legalism to this day remains incredibly attractive to those who subconsciously seek to justify themselves in immoral practices. This is why the Galatian letter begins with strong theological arguments against returning to the Law, and then moves on to tackle practical issues of immorality.</p>
