SS,
Happy to engage. First I should explain that I do not discount the bible as we know it for it has been a huge influence and major contribution to humanity. That said, I think we often think that all civilization is a product of this one tome and that misconception reinforces the notion of exclusivity prevelant throughout christianity. The simple fact is that much of human civilization as we know it is the result of an amalgamation of the contributions of Judiasm, Christianity, Islam, Zoroastrianims, Buddhism, Hinduism and others.
A simple example is the concept of the 0. This concept of a digit which stands for the absense of numerical value, was picked up by the Islamic scientists and connected to the Arabic numbers to make possible tremendous advances in mathematics, algebra, and other forms of higher calculations.
Islam, itself, has contributed immensely to the world of science, and was directly responsible for the reawakening of Christian Europe that had sunk into the dark ages.
I have dwelt only on one small issue but it is an example of an abstract idea that was brought to humanity by a civilization that traces its roots to ancient Hinduism. There are many other examples. As to moral and ethical issues, my investigation evidences to me that all the religions had a moral and ethical standard of pretty much the same. You can compare the Golden Rule for example. When all these religions have common spirtitual (human) values in common, but advocate different social teachings, one wonders if one of those holy books isn't a sort of hologram. You can identify the whole in each of the parts, but the part is still not the same as the whole.
Have I made any sense yet?
