ExB: I think you are throwing in a lot of bad religious leaders in the same boat as the Bible when in fact they are in a complete different boat.
What I mean is, there is no universally agreed-upon framework for judging the truth of religion and religious claims. Science, we are told, cannot do it, since religion deals with metaphysics and with the supernatural, which science (the study of the natural world) cannot be applied to. But there is no acceptance of how to apply metaphysics or "spiritual science" to religious claims in order to determine if there is any truth to any of it. Without that framework, religions make claims that cannot be tested, including by other religions. Which do you trust? Why?
As for science and the Bible, keep in mind that the Bible refers to things like a global flood, which science shows us cannot have happened. Or the resurrection of a man who was dead for more than a day. It tells of an occasion where the display of striped branches caused livestock to give birth to similarly-striped offspring. One of its writers appeared to think that demons caused disease. And so on. I think science works just fine without the Bible. I don't really think the Bible works too well at all.
