Chapter 2 records Paul going to Jerusalem with Barnabas and Titus to visit Church leaders. Paul receives approval from them of his message to the Gentiles that the Gospel gives us freedom in Christ, setting us free of any obligation to obey the Old Testament Law and ceremonial practices. When Peter later comes to Antioch, Paul publicly rebukes Peter for his hypocritical conduct that communicates to the Gentiles they must obey Jewish law and practices. Paul then writes the core theological argument of this letter stating that justification is by faith alone in Christ and salvation requires no works. Paul adds that Christ's death is made meaningless when works of the law are added to Christ's work which is graciously given us as the only means for our salvation.
