Galatians
Paul was correcting wrong thinking that had quickly developed in the congregations of Galatia(Galatians 1:6). Certain Jews were trying to teach that circumcision (and other facets of the Law) were still required among Christians and Paul was reprimanding congregation members for being influenced by their false teachings(Galatians 2:15-3:14; 4:9+10) These ' false brothers', called 'Judaizers', were sly and concerned with their own interests (Acts 15:1/Galatians 2:4). Pretending to represent the congregation in Jerusalem, they discredited Paul and wanted the Christians to get circumcised(Galatians 4:17), to try and stop Jewish persecution of Christians. Paul wrote to the Galatians to remind them that they were no longer under the Mosaic Law(Galatians 2:15-21)(Galatians 1:6-9/Galatians 5:1-12/Galatians 6:12-16), but that they were acceptable to God because of their FAITH in the good news about Jesus (Galatians 3:1-5)(Galatians 4:1-7), and that the 'true sons of Abraham' were those with FAITH like Abraham's (Galatians 3:6-9+26-29).
