To the church in Corinth, Paul addressed pride, sexual licentiousness and cliquish behavior. The Galatians have a different problem. This church is being tempted to believe “another Gospel” (Galatians 1:8-9). As this letter unfolds, it becomes clear Paul’s warning against a different religion isn’t because the Galatians have rejected the story of Jesus’ perfect life, atoning death, and victorious life. Rather, the Galatians are being tempted to believe, if they have not completely succumbed to the idea, that one must become culturally Jewish to be right with God. Due to this belief, some are even preventing Gentiles from enjoying full Christian fellowship. When Paul addresses the Galatians, he challenges a universal problem. This idea, that we must do something to earn someone’s favor, even God’s, is deeply ingrained in all of our mindsets. Moreover, even many Christians fail to treat others as if Jesus’ grace towards all, especially those with struggles or habits we don’t understand, truly makes us brothers and sisters through faith. Consider how Peter reacted to Gentile believers when leaders in the “circumcision group” arrived (Galatians 2:12). Though Peter knew better, he withheld glad welcome of Gentiles and thus confirmed in practice a latent belief that something was missing for these Christians who had not been Jewish prior to conversion. Paul wants link the truth of salvation by faith in Christ with the need for welcoming Gentiles without added stipulation. He could not have done so more powerfully by declaring that through faith he had been crucified with Christ yet was still living on! (Galatians 2:20) The point Paul makes is that when someone believes in Jesus they are so identified with Him that their ethnic heritage isn’t definitive, but our union with Christ truly defines everything about us. The doctrine of justification by faith alone extends beyond just describing the means of our salvation, for it also helps us grasp the power to live as family, like equals, across culture, status, and all of the things that often prevents relationship.
