Of the 27 books in the New Testament, 21 are epistles, or letters, many of which were written by Paul. The names of the epistles attributed to him are Romans; I and II Corinthians; Galatians; Ephesians; Philippians; Colossians; I and II Thessalonians; I and II Timothy; Titus; and Philemon. This is the order of their arrangement in the New Testament.
