Title: Epistle to the Galatians
Content:  The 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 religious male circumcision, by contextualizing the role of the law in light of

Title: Epistle to the Galatians
Content:  The South Galatian view holds that Paul wrote Galatians before the First Jerusalem Council, probably on his way to it, and that it was written to churches he had presumably planted during either his time in Tarsus (he would have traveled a short distance, since Tarsus is in Cilicia) after his first visit to Jerusalem as a Christian, or during his first missionary journey, when he traveled throughout southern Galatia. If it was written to the believers in South Galatia, it would likely have been written in 49.

Title: Epistle to the Galatians
Content:  A majority of scholars agree that Galatians was written between the late 40s and early 50s, although some date the original composition to c. 50–60. Jon Jordan notes that an interesting point to be made in the search for the dating of Galatians concerns whether or not it is a response to the Council of Jerusalem or a factor leading up to the Council. He writes, "did Paul's argument in Galatians flow out of the Jerusalem Council's decision, or did it come before the Jerusalem Council and possibly help shape that very decision?" It would have been enormously helpful to Paul's argument if he could have mentioned the decision of the Council of Jerusalem that Gentiles should not be circumcised. The absence of this argument from Paul strongly implies Galatians was written prior to the council. Since the council took place in 48-49 AD, and Paul evangelized South Galatia in 47-48 AD, the most plausible date for the writing of Galatians is 48 AD.
Title: Epistle to the Galatians
Content:  revelation of Christ. The Epistle to the Galatians has exerted enormous influence on the history of Christianity, the development of Christian theology, and the study of the Apostle Paul. The central dispute in the letter concerns the question of how Gentiles could convert to Christianity, which shows that this letter was written at a very early stage in church history, when the vast majority of Christians were Jewish or Jewish proselytes, which historians refer to as the Jewish Christians. Another indicator that the letter is early is that there is no hint in the letter of a developed organization within the Christian community at large. This puts it during the lifetime of Paul himself.
