The Book of Acts Introduction Authorship
Comparing Luke 1:14 with Acts 1:1: We find that the same author wrote both books. McGarvey notes, “This claim of a common authorship is confirmed by the uniformity of style which pervades the two books. All the evidence, therefore, which tends to prove that Luke wrote our third Gospel has equal force in proof that he wrote the book of Acts. While unbelieving writers in general deny that he wrote either, all admit that the same author wrote both”. 1
Noting the “we” sections of the book: At various places in the Book of Acts the events taking place are cast in the first person plural, indicating that the author was present when these events took place, consider chapters 16:10-17; 20:5-21:18; 27:1-28:16. From these passages we learn: 1. The same author wrote the whole book. 2. The author of the book was one of Paul's traveling companions and was with him in Rome (28:16). 3. Most of Paul's traveling companions are mentioned in contrast to the author. Hence we already know that the author could not have been: Silas, Mark, Barnabas, Timothy (Acts 15:37-16:11), Sopater, Aristarchus, Secundus, Gaius, Tychicus, or Trophimus (20:5). McGarvey notes, “As then the writer was none of these, and yet he journeyed with Paul on his visit to Jerusalem, and thence to Rome, we can identify him with no other than Luke (Colossians 4:1014; Philemon 23-24)” (p. xi).
Luke the Historian: Luke 1:1-4 “Forasmuch as many have taken in hand to draw up a narrative concerning those matters which have been fulfilled among us, even as they delivered them unto us, who from the beginning were eyewitnesses and 1
