Luke's Subtle Autobiography

John Foxe points out that St. Luke was likely a physician in Troas and probably converted there during Paul's ministry. He explains: "Notice in Acts 16:8-10, that it is at Troas that Luke switches from "they" to "we" in his text -- 'And they passing by Mysia came down to Troas. And a vision appeared to Paul in the night; there stood a man of Macedonia, and prayed him, saying, come over into Macedonia, and help us. And after he had seen the vision, immediately we endeavored to go into Macedonia, assuredly gathering that the Lord had called us to preach the gospel unto them.'" (Foxe's Book of Martyrs, 6)
