What's in a name? Paul in Galatians 1:1

Paul begins all his letters with his name; it's worthwhile for exegetical reasons to think a bit on what function it served. Most simply the name serves to denote who the author of the letter is: It is Paul, the missionary apostle who had visited the Galatians in the past and now writes to them with a contemporary challenge. But the connotation that his name brings to this letter should not be overlooked. Just as modern individuals respond emotionally when receiving a letter from a close friend or relative, the Galatians would have had a collective emotional response when Paul’s letter arrived. Paul and the Galatians had a prior relationship with deep bonds shared between them (This is conveyed, for example, by both the tone and content of Gal 4:12-20). He writes to them now not simply to convey information but to exercise pastoral care as a practical function of those bonds. Paul expected that the Galatians would respond to him positively, even in the midst of the current negative situation, and he hoped the mention of his name would invoke in the Galatians strong feelings of association, respect, and love. Paul’s name had rhetorical power because of the past history he and the Galatians shared, and it takes on even more power as the strong, unexpected tone of the letter becomes evident through the beginning of the letter body.
