Are Paul's epistles always found in every New Testament manuscript?
Yes. According to the manuscripts still preserved in museums and libraries, Paul’s epistles—Romans, Corinthians, Galatians, Ephesians, Philippians, Colossians, and so forth—are always present in every New Testament manuscript. They also consistently appear in the same identical order as in our present Bible, unlike other New Testament books, which vary in order.
Les explains that he came across the statement that of all the New Testament manuscripts still in museums and libraries, every one may have the New Testament in various orders. The order is not always Matthew, Mark, Luke, John, nor is Acts always in its usual place, nor the later epistles of Peter and John in the same order. However, Paul’s epistles—Romans, Corinthians, Galatians, Ephesians, Philippians, Colossians, and so forth—are always in every one of these manuscripts and always in the same identical order as in our Bible today. He notes this shook him up, as he lifts Paul somewhat over the rest of the writers, feeling Paul is next to Christ Himself, the greatest human being. He adds that this order is not the order in which they were written: Thessalonians were written first, then even other letters before Romans; Galatians was written before, and even Corinthians was written before Romans.
