he Epistle to the Galatians, often shortened to Galatians, is the ninth book of the New Testament. It is a letter from Paul the Apostle to a number of Early Christian communities in Galatia. Scholars have suggested that this is either the Roman province of Galatia in southern Anatolia, or a large region defined by an ethnic group of Celtic people in central Anatolia. Paul is principally concerned with the controversy surrounding Gentile Christians and the Mosaic Law during the Apostolic Age. Paul argues that the Gentile Galatians do not need to adhere to the tenets of the Mosaic Law, particularly circumcision, by contextualizing the role of the law in light of the revelation of Christ. Galatians has exerted enormous influence on the history of Christianity, the development of Christian theology, and the study of the apostle Paul.
