New Defender's Study Bible Notes
1:2 churches of Galatia. Galatia was not a city, but a Roman province located in what is now north-central and northeastern Turkey. It had earlier been overrun by Gauls, for whom the area was named, but was later incorporated in the Roman Empire. Several of the cities reached on Paul’s first missionary journey (Antioch of Pisidia, Iconium, Lystra, Derbe) were in the area just south of Galatia proper, and could be considered as Galatian churches, but there is no internal evidence to that effect. Possibly the churches to whom Paul was writing were certain unknown churches in Galatia proper, churches that Paul had reached on his second missionary journey.
