Luke was a doctor (Col. 4:14) and a faithful companion of Paul, accompanying him on several journeys. He was with Paul throughout his two-year imprisonments in both Caesarea and Rome. He is the author of the Gospel bearing his name and the book of Acts, where he records his travels with Paul. Little else is known about Luke. Most scholars believe that he was a Gentile. This is based in part on the fact that Paul does not include Luke among the “men of the circumcision” who were his fellow workers (Col. 4:10–11). How Luke came to know Christ is not revealed, though his thorough acquaintance with the OT suggests that he may have been a “God-fearer” like Cornelius before becoming a Christian. (Acts 21:1–8)
