The process of canonization of the New Testament was complex and lengthy. In the initial centuries of
early Christianity, there were many books widely considered by the church to be inspired, but there was no single formally recognized New Testament canon. The process was characterized by a compilation of books that
apostolic tradition considered authoritative in worship and teaching, relevant to the historical situations in which they lived, and consonant with the Old Testament. Writings attributed to the apostles circulated among the
earliest Christian communities and the Pauline epistles were circulating, perhaps in collected forms, by the end of the
1st century AD. One of the earliest attempts at solidifying a canon was made by
Marcion, AD, who accepted only a modified version of Luke (the
Gospel of Marcion) and ten of Paul's letters, while rejecting the Old Testament entirely. His canon was largely rejected by other groups of Christians, notably the
proto-orthodox Christians, as was his theology,
Marcionism.
Adolf von Harnack, John Knox, and
David Trobisch,
Irenaeus and
Tertullian held the
epistles of Paul to be divinely inspired "scripture". Other books were held in high esteem but were gradually relegated to the status of
New Testament apocrypha. Justin Martyr, in the mid
2nd century, mentions "memoirs of the apostles" as being read on Sunday alongside the
"writings of the prophets". The
Muratorian fragment, dated at between 170 and as late as the end of the 4th century (according to the
Anchor Bible Dictionary), may be the earliest known New Testament canon attributed to mainstream Christianity. It is similar, but not identical, to the modern New Testament canon. The oldest clear endorsement of Matthew, Mark, Luke, and John being the only legitimate gospels was written AD. A four gospel canon (the
Tetramorph) was asserted by Irenaeus, who refers to it directly in his
polemic Against Heresies: The books considered to be authoritative by Irenaeus included the four gospels and many of the letters of Paul, although, based on the arguments Irenaeus made in support of only four authentic gospels, some interpreters deduce that the fourfold Gospel must have still been a novelty in Irenaeus's time.
Origen (3rd century) By the early 200s,
Origen may have been using the same twenty-seven books as in the Catholic New Testament canon, though there were still disputes over the canonicity of the Letter to the Hebrews, Epistle of James, II Peter, II John and III John and the Book of Revelation, known as the
Antilegomena. Likewise, the
Muratorian fragment is evidence that, perhaps as early as 200, there existed a set of Christian writings somewhat similar to the twenty-seven book NT canon, which included four gospels and argued against objections to them. Thus, while there was a good measure of debate in the
Early Church over the New Testament canon, the major writings are claimed to have been accepted by almost all Christians by the middle of the
3rd century. Origen was largely responsible for the collection of usage information regarding the texts that became the New Testament. The information used to create the late-4th-century
Easter Letter, which declared accepted Christian writings, was probably based on the
Ecclesiastical History (HE) of
Eusebius of Caesarea, wherein he uses the information passed on to him by Origen to create both his list at HE 3:25 and Origen's list at HE 6:25. Eusebius got his information about what texts were then accepted and what were then
disputed, by the
third-century churches throughout the known world, a great deal of which Origen knew of firsthand from his extensive travels, from the library and writings of Origen. In fact, Origen would have possibly included in his list of "inspired writings" other texts kept out by the likes of Eusebius—including the
Epistle of Barnabas,
Shepherd of Hermas, and
1 Clement. Notwithstanding these facts, "Origen is not the originator of the idea of biblical canon, but he certainly gives the philosophical and literary-interpretative underpinnings for the whole notion."
Eusebius's Ecclesiastical History Eusebius, , gave a detailed list of New Testament writings in his
Ecclesiastical History Book 3, Chapter XXV: : "1... First then must be put the holy quaternion of the gospels; following them the Acts of the Apostles... the epistles of Paul... the epistle of John... the epistle of Peter... After them is to be placed, if it really seem proper, the Book of Revelation, concerning which we shall give the different opinions at the proper time. These then belong among the accepted writings." : "3 Among the disputed writings, which are nevertheless recognized by many, are extant the so-called epistle of James and that of Jude, also the second epistle of Peter, and those that are called the second and third of John, whether they belong to the evangelist or to another person of the same name. Among the rejected [Kirsopp Lake translation: "not genuine"] writings must be reckoned also the
Acts of Paul, and the so-called
Shepherd, and the
Apocalypse of Peter, and in addition to these the extant
epistle of Barnabas, and the so-called
Teachings of the Apostles; and besides, as I said, the
Apocalypse of John, if it seem proper, which some, as I said, reject, but which others class with the accepted books. And among these some have placed also the
Gospel according to the Hebrews... And all these may be reckoned among the disputed books." : "6... such books as the
Gospels of Peter, of
Thomas, of
Matthias, or of any others besides them, and the
Acts of Andrew and
John and the other apostles... they clearly show themselves to be the fictions of heretics. Wherefore they are not to be placed even among the rejected writings, but are all of them to be cast aside as absurd and impious." The Book of Revelation is counted as both accepted (Kirsopp Lake translation: "recognized") and disputed, which has caused some confusion over what exactly Eusebius meant by doing so. From other writings of the church fathers, it was disputed with several canon lists rejecting its canonicity. EH 3.3.5 adds further detail on Paul: "Paul's fourteen epistles are well known and undisputed. It is not indeed right to overlook the fact that some have rejected the Epistle to the Hebrews, saying that it is disputed by the church of Rome, on the ground that it was not written by Paul." EH 4.29.6 mentions the
Diatessaron: "But their original founder, Tatian, formed a certain combination and collection of the gospels, I know not how, to which he gave the title Diatessaron, and which is still in the hands of some. But they say that he ventured to paraphrase certain words of the apostle Paul, in order to improve their style."
4th century and later In his Easter letter of 367,
Athanasius, Bishop of Alexandria, gave a list of the books that would become the twenty-seven-book NT canon, and he used the word "canonized" (
kanonizomena) in regards to them. The first council that accepted the present canon of the New Testament may have been the
Synod of Hippo Regius in North Africa (393 AD). The acts of this council are lost. A brief summary of the acts was read at and accepted by the
Council of Carthage (397) and the
Council of Carthage (419). These councils were under the authority of
St. Augustine, who regarded the canon as already closed.
Pope Damasus I's
Council of Rome in 382, if the
Decretum Gelasianum is correctly associated with it, issued a biblical canon identical to that mentioned above, Thus, some claim that, from the
4th century, there existed unanimity in the
West concerning the New Testament canon (as it is today), and that, by the
5th century, the
Eastern Church, with a few exceptions, had come to accept the
Book of Revelation and thus had come into harmony on the matter of the canon. Nonetheless, full dogmatic articulations of the canon were not made until the
Canon of Trent of 1546 for
Roman Catholicism, the
Thirty-Nine Articles of 1563 for the
Church of England, the
Westminster Confession of Faith of 1647 for
Calvinism, and the
Synod of Jerusalem of 1672 for the
Greek Orthodox. On the question of NT Canon formation generally, New Testament scholar Lee Martin McDonald has written that: According to the
Catholic Encyclopedia article on the Canon of the New Testament: "The idea of a complete and clear-cut canon of the New Testament existing from the beginning, that is from Apostolic times, has no foundation in history. The Canon of the New Testament, like that of the Old, is the result of a development, of a process at once stimulated by disputes with doubters, both within and without the Church, and retarded by certain obscurities and natural hesitations, and which did not reach its final term until the dogmatic definition of the
Tridentine Council." In 331,
Constantine I commissioned Eusebius to deliver
fifty Bibles for the
Church of Constantinople.
Athanasius (
Apol. Const. 4) recorded Alexandrian scribes around 340 preparing Bibles for
Constans. Little else is known, though there is plenty of speculation. For example, it is speculated that this may have provided motivation for canon lists, and that
Codex Vaticanus and
Codex Sinaiticus may be examples of these Bibles. Together with the
Peshitta and
Codex Alexandrinus, these are the earliest extant Christian Bibles. ==Early manuscripts==
