The New Testament ascribes authorship of its 27 books to 8 men, each of whom is revealed in its pages to be either an apostle or working under the direct supervision of an apostle. Thus James and Jude – the brothers of the Lord – take their place among the apostles after the resurrection (e.g. Acts 1:14 and 1 Corinthians 9:5.), while Mark and Luke – by virtue of their status as co-workers – are deemed “apostolic men.”
Here then are the eight apostolic authors named in the New Testament in the order of the appearance of the first (or only) book ascribed to each. I have put all books ascribed to each author in parentheses after his name.
Matthew (Matthew) – There is only one Matthew mentioned in the New Testament (Matt 9:9; 10:3; Mark 3:18; Luke 6:15; Acts 1:13), and he is one of the original twelve apostles.
Mark (Mark) – There is only one “Mark” mentioned in the New Testament (Acts 12:12, 25; 15:37, 39; Col 4:10; 2 Tim 4:11; Phile 1:24; 1 Pet 5:13), and he is the one also called John who was a co-worker of Barnabas (as well as his cousin), Paul, and Peter.
Luke (Luke, Acts) – There is only one “Luke” mentioned in the New Testament (Col 4:14; 2 Tim 4:11; Phile 1:24), and he is the one who was a co-worker of Paul’s.
John (John, 1 John, 2 John, 3 John, Revelation) – Although there are several persons in the New Testament named “John,” this is John the son of Zebedee who was one of the original twelve apostles.
Paul (Romans, 1 Corinthians, 2 Corinthians, Galatians, Ephesians, Philippians, Colossians, 1 Thessalonians, 2 Thessalonians, 1 Timothy, 2 Timothy, Titus, Philemon, Hebrews) – There is only one person named “Paul” in the New Testament, and he is the apostle who had originally been known as Saul of Tarsus.
James (James) – Although there are several persons named “James” in the New Testament, this is the brother of Jesus (i.e. another son of Mary)
Peter (1 Peter, 2 Peter) – There is only one person in the New Testament named “Peter,” and he is the one who was among the original twelve apostles.
Jude (Jude) – There is only one person named “Jude” in the New Testament, and he is the brother of Jesus and James (i.e. also a son of Mary).
