text: Audience Paul's letter is addressed "to the churches of Galatia", but the location of these churches is a matter of debate. Most scholars agree that it is a geographical reference to the Roman province in central Asia Minor, which had been settled by immigrant Celts in the 270s BC and retained Gaulish features of culture and language in Paul's day. Acts records Paul traveling to the "region of Galatia and Phrygia", which lies immediately west of Galatia. Some scholars have argued that "Galatia" is an ethnic reference to Galatians, a Celtic people living in northern Asia Minor.
  The New Testament indicates that Paul spent time personally in the cities of Galatia (Antioch of Pisidia, Iconium, Lystra and Derbe) during his missionary journeys. They seem to have been composed mainly of Gentile converts. After Paul's departure, the churches were led astray from Paul's trust/faith-centered teachings by individuals proposing "another gospel" (which centered on salvation through the Mosaic Law, so-called legalism), whom Paul saw as preaching a "different gospel" from what Paul had taught. The Galatians appear to have been receptive to the teaching of these newcomers, and the epistle is Paul's response to what he sees as their willingness to turn from his teaching.
