I just have a sense that, you know, I'm curious about what is religion about, you know? Why do some of us still engage it? It's not because it's a set of old beliefs or old ideas. Or even, particularly, the view that this is the only true religion. Many of us no longer accept those views.

There are some kinds of Christianity that insist you have to believe literally in doctrine. The Gnostic gospels open out the complexity and multiplicity of approaches to this. If you think the story of the virgin birth is mistranslated, for instance, it doesn't mean you have to throw out the whole thing.

People who are comfortable with very clear boundaries and group definitions don't like the instability and ambiguity of people who say they are more advanced Christians, or they don't have to do what the bishop says.

Startling as the Gospel of Judas sounds, it amplifies hints we have long read in the Gospels of Mark and John that Jesus knew and even instigated the events of his passion, seeing them as part of a divine plan.

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?

I study religion because I find it fascinating and problematic. But I struggle with the idea of what religion is, what being religious means. A lot of people assume that if you write about early Christianity, you must be some kind of Sunday-school teacher.
