Since many have undertaken to set in order a narrative concerning those matters which have been fulfilled among us,
    Luke seems to have been the only Gentile writer of the New Testament. Paul wrote that, of his fellow-workers, Aristarchus, Mark and John were the only ones who were Jewish. The others (Epaphras, Luke, and Demas) were therefore probably Gentiles. Paul referred to Luke as a physician (Colossians 4:14), and evidence from passages in Luke and Acts seem to corroborate this.
