If I read something and find it useful, I try to use it. I find much of what Jesus is reputed to have said as useful. I could say the same of Lao-Tse, Buddha, Krishna, etc...a study of all great religions soon leads to a greater tolerance and respect for all of them, and a recognition that they have much in common.

This eclectic process is a quite sensible approach for a personal spiritual belief. But picking-out the good bits and trying to cover-up the bad bits of the founding tenets of an organised religion in is not very really sensible. Especially as this 'spin' is done in the same way you would sell a politician or party. Do you not think that good old St Paul was probably one of the first spin doctors and made a very effective one at that?

It could be argued that the fundamentalist route is the only true way to hold the beliefs of an organised religion.

That way is at least honest. For if an organised relgion is founded on a core belief as fact - a story like the various creation myths or imaculate conception - folk can clearly see and decide for themselves if it (and its various sects) is for them, can choose another that does suit them better, pick and choose bits from all of them or choose not believe any of them or indeed choose not to believe in anything at all.
