Q
May I ask what is Luke’s nationality? Or if he is a Jew, a gentile or a mixture of both?
A
The Bible doesn’t reveal Luke’s nationality, but from historical sources we learn that he was born in Antioch, Syria and is thought by many to have been a Gentile. Paul seems to have confirmed this, leaving Luke off a list of Jews who were traveling with him, then mentioning him separately as also being present (Colossians 4:10-11, 14). If so, Luke was the only Gentile author in the New Testament.
Luke was well educated in the Greek culture, and a physician by profession. He was the author of both the Gospel that bears his name and the book of Acts, which were at one time were two parts of a single document.
