The Pauline epistles were circulating in collected form by the end of the 1st century. By the early 3rd century, there existed a set of Christian writings similar to the current New Testament, though there were still disputes over the canonicity of Hebrews, James, I Peter, I and II John, and Revelation. By the 4th century, there existed unanimity in the West concerning the New Testament canon, and by the 5th century the East, with a few exceptions, had come to accept the Book of Revelation and thus had come into harmony on the matter of the canon.
