Constantine was a Roman Emperor who lived from 274 to 337 A.D. Constantine called the Council of Nicea—the first general council of the Christian church, 325 A.D.—primarily because he feared that disputes within the church would cause disorder within the empire. It is debated whether or not Constantine was actually a believer (according to his confessions and understanding of the faith) or just someone trying to use the church and the faith to his own advantage. Constantine, and the Council of Nicea, had virtually nothing to do with the forming of the canon, but facilitated it’s publication.
The council that formed an undisputed decision on the canon took place at Carthage in 397, sixty years after Constantine’s death. However, long before Constantine, 21 books were acknowledged by all Christians (the 4 Gospels, Acts, 13 Paul, 1 Peter, 1 John, Revelation). There were 10 disputed books (Hebrews, James, 2 Peter, 2-3 John, Jude, Ps-Barnabas, Hermas, Didache, Gospel of Hebrews) and several that most all considered heretical—Gospels of Peter, Thomas, Matthaias, Acts of Andrew, John, etc…
