It is called The Good Man Jesus And The Scoundrel Christ, by Philip
Pullman. Essentially, he has reinterpreted and rewritten the traditional
gospels to suggest more natural explanations for apparent miracles and
the stories associated with Jesus (for example, when the wine ran out in Cana, Jesus just "had a word" with the management). There is a side story running where
the Scoundrel Christ (Jesus' twin) is persuaded to transcribe his
brother's activities in a more "immortal" light, for the good of the
world and to give future generations hope. It's really interesting.
Anyway, among other things, the afterword discusses the role of Judas
and Jesus' "ultimate" miracle, the resurrection. Pullman alludes to the
idea that the whole of Christianity is strongly centred on the premise
that Jesus died and rose, in order to absolve humanity. If that's the
case though, then Jesus HAD to be betrayed by Judas to the authorities
(otherwise he wouldn't have been crucified). In which case, how is what
Judas did called a "betrayal"? And knowing that without the
ressurection, the basis of Christianity would be less, erm, hopeful
regarding absolution/afterlife/etc, would you, in Judas' position,
betray or not betray?
As an atheist, I find it an interesting premise. I wondered what some of the believers round these parts thought.
Don't be fooled by their innocent looks. All Emmas Are Evil. And they're coming for you.
