FootnotePaul wrote this letter to the Christian brethren in Galatia (now southern Turkey) . He had founded the congregations there (Acts 13 and 14) with much success on his first missionary journey, revisiting them on his subsequent second (Acts 16:6) and third (Acts 18:23) missionary journeys. However, "Judaizers" had crept into the church and persuaded the non-Jewish believers that they had to be circumcised and keep the law of Moses; Paul's letter primarily addressed this issue.
