What do you think of this as an idea for a play?

I think if you were to ask a theologian that question he would absolutely say that Yes!, Jesus intended his teachings to become a religion. (St.) Peter was the rock upon he built his Church. Period! Which Christian groups are you referring too, in particular? I don't know that any one or sevral are fanatical as such. What do you mean by fanatical? I don't know that any Christian group are using their beliefs, ie: The Bible - to start Holy War. Perhaps you are mixing things up with those Muslims who misinterpret the Alcoran? Those that have got us into this disorderly accumulation of hate and violence around the world. And more... As far as I'm willing to go back...? There's plenty of evidence available, now, in our present history to draw inspiration from, me thinks. I apologize in advance if that sounds wrong to you, I understand you were just wanting to make a positive contribution. Perhaps don't latch on to a topic so hard next time around. Peace out.
