Book order

The order in which the books of the New Testament appear differs between some collections and ecclesiastical traditions. In the Latin West, prior to the Vulgate (an early 5th-century Latin version of the Bible), the four Gospels were arranged in the following order: Matthew, John, Luke, and Mark. The Syriac Peshitta places the major Catholic epistles (James, 1 Peter, and 1 John) immediately after Acts and before the Pauline epistles.

The order of an early edition of the letters of Paul is based on the size of the letters: longest to shortest, though keeping 1 and 2 Corinthians and 1 and 2 Thessalonians together. The Pastoral epistles were apparently not part of the Corpus Paulinum in which this order originated and were later inserted after 2 Thessalonians and before Philemon. Hebrews was variously incorporated into the Corpus Paulinum either after 2 Thessalonians, after Philemon (i.e. at the very end), or after Romans.

Luther's canon, found in the 16th-century Luther Bible, continues to place Hebrews, James, Jude, and the Apocalypse (Revelation) last. This reflects the thoughts of the Reformer Martin Luther on the canonicity of these books.
