the evangelist, was a Gentile. The date and circumstances of his conversion are unknown. According to his own statement ( Luke 1:2 ), he was not an "eye-witness and minister of the word from the beginning." It is probable that he was a physician in Troas, and was there converted by Paul, to whom he attached himself. He accompanied him to Philippi, but did not there share his imprisonment, nor did he accompany him further after his release in his missionary journey at this time ( Acts 17:1 ). On Paul's third visit to Philippi ( Acts 20:5 Acts 20:6 ) we again meet with Luke, who probably had spent all the intervening time in that city, a period of seven or eight years. From this time Luke was Paul's constant companion during his journey to Jerusalem ( (20:6-21:18). ). He again disappears from view during Paul's imprisonment at Jerusalem and Caesarea, and only reappears when Paul sets out for Rome ( 27:1 ), whither he accompanies him ( Acts 28:2 Acts 28:12-16 ), and where he remains with him till the close of his first imprisonment ( Philemon 1:24 ; Colossians 4:14 ). The last notice of the "beloved physician" is in 2 Timothy 4:11 .
There are many passages in Paul's epistles, as well as in the writings of Luke, which show the extent and accuracy of his medical knowledge.

(light-giving ), or Lucas, is an abbreviated form of Lucanus. It is not to be confounded with Lucius, ( Acts 13:1 ; Romans 16:21 ) which belongs to a different person. The name Luke occurs three times in the New Testament-- ( Colossians 4:14 ; 2 Timothy 4:11 ); Phle 1:24 --and probably in all three the third evangelist is the person spoken of. Combining the traditional element with the scriptural we are able to trace the following dim outline of the evangelists life. He was born at Antioch in Syria, and was taught the science of medicine. The well known tradition that Luke was also a painter, and of no mean skill, rests on the authority of late writers. He was not born a Jew, for he is not reckoned among those "of the circumcision" by St. Paul. Comp. ( Colossians 4:11 ) with ver. 14. The date of his conversion is uncertain. He joined St. Paul at Troas, and shared his Journey into Macedonia. The sudden transition to the first person plural in ( Acts 16:9 ) is most naturally explained after all the objections that have been urged, by supposing that Luke the writer of the Acts, formed one of St. Pauls company from this point. As far as Philippi the evangelist journeyed with the apostle. The resumption of the third person on Pauls departure from that place, ( Acts 17:1 ) would show that Luke was now left behind. During the rest of St. Pauls second missionary journey we hear of Luke no more; but on the third journey the same indication reminds us that Luke is again of the company, ( Acts 20:5 ) having joined it apparently at Philippi, where he had been left. With the apostle he passed through Miletus, Tyre and Caesarea to Jerusalem. ch. Acts 20:6; 21:18 As to his age and death there is the utmost uncertainty. He probably died a martyr, between A.D. 75 and A.D. 100. He wrote the Gospel that bears his name, and also the book of Acts.
