What New Testament books were written before Paul died?

A:

Very few New Testament books were written by Saint Paul or during his lifetime. The Book of Hebrews is generally believed to have been written before Paul died, although not by him.

Thirteen epistles are traditionally attributed to Paul (Romans, 1 Corinthians, 2 Corinthians, Galatians, Ephesians, Philippians, Colossians, 1 Thessalonians, 2 Thessalonians, 1 Timothy, 2 Timothy, Titus and Philemon), but only seven are considered undisputed Pauline epistles and therefore written by him - and during his lifetime: Romans, 1 Corinthians, 2 Corinthians, Philemon, Galatians, Philippians and 1 Thessalonians. The remaining Pauline epistles were written in Paul's name, long after he died.

It has been well established that the earliest New Testament gospel, now known as Mark's Gospel, was written around 70 CE, almost certainly after the death of Paul. The general epistles were also written after the death of Paul.
