This study asks when each of the twenty-seven books that are now collected in the corpus known as the New Testament were written. It will additionally ask when four extracanonical texts (1 Clement, Didache, Epistle of Barnabas, and Shepherd of Hermas) were written. It will conclude that, with the notable exception of the undisputed Pauline Epistles, the majority of the texts that were eventually incorporated into the New Testament corpus were likely written twenty to thirty years earlier
