I can't really picture myself truly being a Christian in any meaningful sense. Belief in some form of Abrahamic deity is very much a deal breaker for me. Not negotiable.
Were I pushed to the wall (I sort of was, long ago) I would probably become quite the troublemaker, lapse-prone Catholic, Anglican/Episcopalian or, if somehow I happened to be highly motivated yet also Christianity-oriented, I want to believe that I would attempt to be an Amish (probably for a very short while...)
I can assure you that I would be either unrecognizable or very uninterested in even using any god-concepts, though. I'm apatheistic as heck.
