The canonization of the New Testament in the fourth century

In his Easter letter of 367 CE, Athanasius, the bishop of Alexandria, gave a list of the books that would become the 27 book New Testament canon.  He actually used the word canonized, (κανονιζόμενα).  The first council that accepted the present canon of the New Testament may have been the Synod of Hippo Regius in North Africa in 393 CE.  In 397 CE and 419 CE, the Councils of Carthage, also in North Africa, accepted this canonical 27 number of books.  These North African councils were under the authority of St. Augustine (354-430 CE), who regarded the canon as already closed.  Pope Damasus I (366-384 CE) in the Council of Rome in 382 CE, issued the same biblical canon.  This same Pope Damasus I commissioned St. Jerome (347-420 CE) to translate and produce the Latin Vulgate edition of the Bible around 383 CE.  Thus, the fixation of the canon in the West was complete at the end of the 4th century CE.

The other Pauline letters

Five other Pauline associated epistles are also part of the New Testament canon.  They include the letters to Timothy, 1 Timothy and 2 Timothy from the late 60s-100 CE.  There is also the letter to Titus, from the late 60s-100 CE, and the letter to Philemon, from the late 50s to the early 60s CE.  Finally, there is the letter to the Hebrews, from the late 60s-100 CE.  As opposed to the letters addressed to Christian communities, these later epistles were addressed to individuals or groups.  Their ties to Paul are less certain than the early letters to the various early developing Christian community churches.
