But I think my favourite interpretation that I've heard so far is that the stories in the Bible are like the protective husk that preserves the kernel of truth. The stories are catchy and have stuck, unwittingly allowing the truth to be carried across the centuries, safely hidden in the minds of men who did not understand it, until the day comes when people grow up enough, to the point where they could crack the shell and eat the fruit.
I really like how that sounds like, but of course, there are probably not many others who see it in that light. Luckily for me, these days they don't burn heretics any more (at least where I live :)).
