Completing his New Testament trilogy, eminent theologian Bruce Metzger provides information from Church history concerning the recognition of the canonical status of the several books of the New Testament. Canonization was a long and gradual process of sifting through scores of gospels, epistles, and other books that enjoyed local and temporary authority—some of which have only recently come to light. Metzger discusses the external pressures that led to the fixing of the limits of the canon as well as Patristic evidence that bears on the development of the canon, not only in the West, but also among the Eastern churches. He also considers differences as to the sequence of the books in the New Testament.
