Colossians 4:14

“Luke, the beloved physician, etc.] Luke the Evangelist, though some doubt it, is here intended, who was a constant companion of the apostle in his troubles, and went with him to Rome, as the Acts of the Apostles wrote by him show, and as from (<550411>2 Timothy 4:11) it appears; so Jerom f62 calls the Evangelist Luke, the physician of Antioch, for from thence he was; and being converted by the Apostle Paul, as is very probable, though some make him to be one of the seventy disciples, he became of a physician of bodies, a physician of souls: some say f63 he was a scholar of Galen, the famous physician, and others that he was his sister's son; who having heard of Christ's miracles, set out…”

“It is conjectured that Luke "the beloved physician" (the same as the Evangelist), may have first become connected with Paul in professionally attending on him in the sickness under which he labored in Phrygia and Galatia (in which latter place he was detained by sickness), in the early part of that journey wherein Luke first is found in his company (Act 16:10; compare Note, see on Gal 4:13). Thus the allusion to his medical profession is appropriate in writing to men of Phrygia. Luke ministered to Paul in his last imprisonment (Ti2 4:11). Demas--included among his "fellow laborers" (Plm 1:24), but afterwards a deserter from him through love of this world (Ti2 4:10). He alone has here no…”

“Luke, the beloved physician - This was undoubtedly the author of the Gospel which bears his name, and of the Acts of the Apostles.

From Colossians 4:11, it is evident that he was not by birth a Jew, but was probably a proselyte. He is supposed to have been a native of Cyrene, and to have died in Achaia, soon after the martyrdom of Paul, at the advanced age of 84. See Rob. Cal. Art. Luke. He is here mentioned as a physician, and in his Gospel, and in the Acts , there are incidental evidences that he was acquainted with the science…”

“Luke, the physician - Such he had been, at least, if he was not then. Colossians 4:15”

“4:14 Luke, the beloved doctor, is well known as the author of Acts and the Gospel bearing his name. This verse is the sole evidence for two facts about Luke: He was a doctor, and he was not a Jewish believer (see Col 4:10-11). • In contrast to the other people mentioned in this passage, no details are given about Demas. Perhaps Paul did not know him well. Demas later deserted Paul (2 Tim 4:10).”
