Biblical Canon

Main article: Biblical Canon See also: Deuterocanonical books and Apocrypha

The Biblical canon is the set of books Christians regard as divinely inspired and thus constituting the Christian Bible. Though the early church used the Old Testament according to the canon of the Septuagint (LXX), the apostles did not otherwise leave a defined set of new scriptures; instead the New Testament developed over time.

The writings attributed to the apostles circulated amongst the earliest Christian communities. The Pauline epistles were circulating in collected form by the end of the 1st century AD. The Bryennios list is an early Christian canon found in Codex Hierosolymitanus and dated to around 100. Justin Martyr, in the early 2nd century, mentions the "memoirs of the apostles", but his references are not detailed. Around 160 Irenaeus of Lyons argued for only four Gospels (the Tetramorph), and argued that it would be illogical to reject Acts of the Apostles but accept the Gospel of Luke, as both were from the same author. By the early 200's, Origen may have been using the same 27 books as in the modern New Testament, though there were still disputes over the canonicity of Hebrews, James, II Peter, II and III John, and Revelation, see Antilegomena. Likewise by 200 the Muratorian fragment shows that there existed a set of Christian writings somewhat similar to what is now the 27-book New Testament.

In his Easter letter of 367, Athanasius, Bishop of Alexandria, gave a list exactly the same in number and order with what would become the New Testament canon and be accepted by the Greek church. The African Synod of Hippo, in 393, approved the New Testament, as it stands today, together with the Septuagint books, a decision that was repeated by Councils of Carthage in 397 and 419. Pope Damasus I's Council of Rome in 382, only if the Decretum Gelasianum is correctly associated with it, issued a biblical canon identical to that mentioned above. In 405, Pope Innocent I sent a list of the sacred books to a Gallic bishop, Exsuperius of Toulouse. Nonetheless, a full dogmatic articulation of the canon was not made until the Council of Trent in the 16th century.
