Were the cities of Colossae, Ephesus, Pergamos, and Thyatira all located in the same region?
Yes. Colossae, Ephesus, Pergamos, and Thyatira were all in the same geographical area, the region of Asia Minor in western Turkey. Ephesus was located on the western coast there, and Paul had his greatest work in that area. They shared one region.
Les explains that Colossae, Ephesus, Pergamos, and Thyatira were all in that same geographical area. He identifies the broader region as Asia Minor and notes it reached the western coast of Turkey, where Ephesus was located. In that area of Asia Minor, Paul had his greatest work. Les also mentions that the next program will briefly look at Paul's message in the Jewish synagogue in Antioch of Pisidia—not the Antioch in Syria, but the one in western Turkey—where Paul rehearses Israel's history.
