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.
