Introduction
1. Life of St. Luke. The word 'Luke' (Loukas) is a contraction of the Latin name Lucanus, often found in inscriptions.
St. Luke was a Gentile, or, as others think, a proselyte, of Antioch in Syria, where he followed the profession of a physician (Colossians 4:14). His connexion with Antioch which tradition affirms, is confirmed by the 'Western' reading of Acts 11:28, which implies that St. Luke was present when the prophet Agabus delivered his famous prophecy before the Church of Antioch. The same passage proves that he was not a convert of St. Paul, but one of the earliest members of the Church of Antioch, which apparently had from the beginning baptised Gentiles as well as Jews (see on Acts 11:20, where the true reading is 'Greeks').
He became a follower of St. Paul, and his companion in his missionary journeys. Many facts about his travels with St. Paul can be gathered from the Acts, because, though he does not name himself, he generally speaks of the Apostle's party as 'we' when he was present, and 'they' when he was absent. It thus appears that he joined the apostle at Troas on the Second Missionary journey (about 50 a.d.), and accompanied him to Philippi (Acts 16:10). Here St. Paul left him (Luke 17:1). After this for several years we cannot trace his movements, but he was probably engaged in missionary work in the district, for when St. Paul returned to Philippi some seven years later on his third missionary journey, St. Luke was still there (Acts 20:5). He then accompanied St. Paul on the rest of his travels until they reached Rome about 59 or 60 a.d.
During St. Paul's first imprisonment St. Luke was with him, though perhaps not continuously (Colossians 4:14; Philemon 1:24). He was also a companion of St. Paul during his second imprisonment (about 67 a.d.), when the Apostle was expecting martyrdom (2 Timothy 4:11).
Nothing certain is known of St. Luke's subsequent life. A third-century authority says, 'Luke, by nation a Syrian of Antioch, a disciple of the apostles, and afterwards a follower of St. Paul, served his master blamelessly till his confession (martyrdom?). For having neither wife nor children he died in Bithynia at the age of 74, filled with the Holy Ghost.'
