The Book of Revelation is the strangest book in the Bible, and the most controversial. Instead of stories and moral teaching, it offers only visions - dreams and nightmares, the Four Horsemen of the Apocalypse, earthquakes, plagues and war.

Rediscovering the controversies that occupied early Christianity sharpens our awareness of the major issue in the whole debate, then and now: What is the source of religious authority? For the Christian the question takes more specific form: What is the relation between the authority of ones own experience and that claimed for the scriptures, the ritual and the clergy?

What is clear is that the Gospel of Judas has joined the other spectacular discoveries that are exploding the myth of a monolithic Christianity and showing how diverse and fascinating the early Christian movement really was.

Why did the consensus of Christian churches not only accept these astonishing views but establish them as the only true form of Christian doctrine? . . . these religious debates - questions of the nature of God, or of Christ - simultaneously bear social and political implications that are crucial to the development of Christianity as an institutional religion. In simplest terms, ideas which bear implications contrary to that development come to be labeled as 'heresy'; ideas which implicitly support it become 'orthodox.'

Possession of books denounced as heretical was made a criminal offense. Copies of such books were burned and destroyed. But in Upper Egypt, someone, possibly a monk from a nearby monastery of St Pachomius, took the banned books and hid them from destruction - in the jar where they remained buried for almost 1,600 years.

The efforts of the majority to destroy every trace of heretical 'blasphemy' proved so successful that, until the discoveries at Nag Hammadi, nearly all our information concerning alternative forms of early Christianity came from the massive orthodox attacks upon them.

Although the gospels of the New Testament-- like those discovered at Nag Hammadi-- are attributed to Jesus' followers, no one knows who actually wrote any of them.
