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?

Contemporary Christianity, diverse and complex as we find it, actually may show more unanimity than the Christian churches of the first and second centuries. For nearly all Christians since that time, Catholics, Protestants, or Orthodox, have shared three basic premises. First, they accept the canon of the New Testament; second, they confess the apostolic creed; and third, they affirm specific forms of church institution. But every one of these - the canon of Scripture, the creed, and the institutional structure - emerged in its present form only toward the end of the second century.

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.'

The idea that each individual has intrinsic, God-given value and is of infinite worth quite apart from any social contribution - an idea most pagans would have rejected as absurd - persists today as the ethical basis of western law and politics. Our secularized western idea of democratic society owes much to that early Christian vision of a new society - a society no longer formed by the natural bonds of family, tribe, or nation but by the voluntary choice of its members.

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.

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.

It is the winners who write history - their way.
