The majority of the letters in the New Testament, known as the Epistles, were written by the Apostle Paul. He is traditionally credited with authoring 13 letters addressed to churches and individuals, including Romans, 1 and 2 Corinthians, Galatians, Ephesians, Philippians, Colossians, 1 and 2 Thessalonians, 1 and 2 Timothy, Titus, and Philemon
. While Paul wrote the most books (letters) in the New Testament, by total word count, Luke actually contributed the largest volume of text because his writings include both the Gospel of Luke and the Acts of the Apostles, which together exceed the length of all Paul's letters combined
. In summary:
- Most letters (by number of books): Apostle Paul (13 letters)
- Largest volume of text (by word count): Luke (Gospel of Luke + Acts)
Other New Testament letters were written by apostles such as Peter, John, James, and Jude, but Paul remains the most prolific letter writer in terms of the number of epistles attributed to him
