Understanding the origins of what we 'accept' these days can be a sobering experience. It shows the all-too-human influence on the holy word. But it can tell us a lot about ourselves and our history and is really a LOT of fun!
But that doesn't mean that the BIble is rendered meaningless and useless. One can gain a lot of useful information from the Bible because it shows a great deal of insight on how
people function.
I fail to believe in a supernatural part of the universe but a goodly amount of my views of life are informed by a "Christian view". I think all people are flawed ("fallen" if you like) and that we are all in need of "salvation"...I just feel that our "salvation" comes from our common humanity.
No one "earns" the "grace" of others forbearance for our flaws but if we all recognize our common failures we should act such that as others would do unto us we should do likewise to them.
There is no single "supreme sacrifice" by Christ on the Cross but there's countless individual
sacrifices we make for each other. We moderate our appetites so that others may sit at the table. We remember the poor because it could be us and maybe one day will be us.
We should not live by the sword because then we will die by it. We should not judge lest our flaws be judged and they are there to be judged.
It's possible to utilize a lot of the Christian foundational principals and have a relatively robust morality
even in the abscence of a supernatural component.
That's why I call myself a "Christian Atheist".
