Galatians 1: Paul's Apostolic Credentials
Part 2 of the study on Galatians, covering Galatians 1:10-2:10
In order to repudiate the rumors and false claims against him, the apostle Paul spends a significant amount of time in his letter laying out his apostolic credentials. As mentioned previously, there were agitators amongst the churches of Galatia attempting to attack not only the gospel but also the messenger. These people were generally Judaizers, or those that still considered circumcision (works) a requirement for justification, along with regarding Old Testament Levitical law binding upon Christians.
Paul strikes quickly in Galatians 1:10, asking, "For am I now seeking the approval of man, or of God?" One of the charges levied against him was that he was preaching an easy form of the gospel, which required no obedience to Levitical law, only faith in Jesus as Messiah. Paul, here, is making the claim that if he were still trying to please man (for example, as he was previously in Judaism), that he would not be a servant of Christ. The takeaway is that he has become a willing servant, not coerced. This servitude ended up costing Paul a great deal of suffering and sacrifice, something a man-pleasing person would unlikely do.
In Galatians 1:11-17, Paul lays out where he received the gospel from as well as what he did (and did not) do. Verses 11-12 note that the gospel he received was not of human origin but of God alone - repelling his opponents' charge that he was in rebellion against the other apostles in Jerusalem by preaching what he preached. There's a strong distinction that he did not receive religious instruction in the rabbinic tradition that mixed scripture with human interpretation. As recounted in the book of Acts, Paul received the truth of the gospel directly from Christ Jesus on the road to Damascus, not from any man. Verses 13-14 explain a bit of the known history about Paul, noting that prior to his conversion he was an extremely zealous rabbi advancing quickly beyond his contemporaries, until verses 14-17 where he contrasts that with God's will and purpose that set him apart from others even before the womb, eventually being called by Christ for His purpose. Paul finishes this section by pointing out that he did not immediately go to Jerusalem to consult with anyone but instead traveled to Arabia and Damascus. The word "consult" here has the connotation of submitting something before someone for comment and/or approval. He did meet with Ananias three days after his conversion (Acts 9:10-19, Acts 22:12-16) but was not meeting with this sense in mind. Rather, Ananias' role was to confirm Paul's calling to preach as well as baptize him.
Verses 18-24 continue Paul's story, explaining that he visited Jerusalem after three years, visiting with Cephas and only seeing James, the brother of Jesus. Afterwards he traveled to other areas, being relatively unknown except by reputation - that he was the one that had been persecuting the church and attempting to destroy it, only to now be preaching the gospel that he once so zealously attacked. For this amazing heart and mind change, scripture tells us that they glorified God because of it.
The first ten verses of chapter 2 continues to provide more of Paul's story, chronicling his next trip to Jerusalem (v1-6) and his meeting with James, Cephas, and John, where they pledged fellowship to and friendship with one another. Since this follows in the vein of chapter 1, I suggest you read the passage for yourself as it is fairly straightforward.
For more context, I suggest picking up a Reformation Study Bible and/or a Macarthur Study Bible - preferably both, as the study notes focus on different things and help to round out one's understanding. Also, if you're on a budget, check out E-Sword, a free bible study tool with a lot of good resources, some free, some for purchase. I'm being edified greatly by the Matthew Henry commentary that's available. Blessings to you all!
