The evangelist, probably the same person who is called by St. Paul, "the beloved physician," Colossians 4:14. The name Luke, or Lucas, Philemon 1:24, is the same as Lucanus in Latin. Luke was the writer of the gospel, which bears his name, and of the Acts of the Apostles, having been the friend and companion of St. Paul in most of the journeys recorded in the latter book. Thus, in Acts 16:11, he first uses the word "we," and shows that he was with Paul at Troas and in his first Macedonian tour. After they reach Philippe, an interval of separation occurs; but they are again together at Philippi when Paul sails thence for Jerusalem, and from that time he continues with the apostle in his labors, voyages, and sufferings, to the close of his first imprisonment at Rome, Acts 17:1 20:5,6,13-16 21:1-28:31 Philemon 1:24 2 Timothy 4:11. His personal history before and after this period of his companionship with Paul, is unknown, or rests on uncertain traditions. His own narrative contains the least possible mention of himself; yet we cannot doubt that he was eminently useful to the early church, by his learning, judgment, fidelity, and even his medical skill, besides leaving to the church universal the invaluable legacy of his writings.
