Annah, thank you for your very well explained response to my earlier post. While I don't agree with a policy that never allows change, I do know that there is a strong fear component that many have towards change, though that fear is mostly unfounded.
It has been said one of the best things the U.S. founding fathers did was create a constitution that allows for change. People change, societies change so the rules we live by should too. I do believe if ancient people had adopted that kind of thing long ago when writing what would become religious texts, the concept of change would be universally accepted today. There's something about "ancient" we tend to attach great value to but how to live and getting advice for how to handle a given situation in the present day shouldn't be included.
Most people today have enough sense to know assembling a crucifixion mob is frowned upon, as is public stoning and things like that. The torture and killings that were carried out centuries ago began with passing judgment on others, often based on religious beliefs. And while we, as a society, are not as barbaric as we were back then, we still feel we have a right and at times almost a duty, to pass judgment on others and punish them in whatever way is legally permissible, or illegally if you think you can get away with it.
That's what should be changed and I fail to see any logical reason why each and every religious faction wouldn't want to implement those kinds of changes. Every belief system I am aware of has, at its core, a basic rule we should treat each other well. It's all the other stuff that is heaped upon that that causes people to believe there are exceptions to that rule. Simplifying and clarifying ancient writings in a way the everyday person today can easily understand, and done in such a way as to convey that basic rule, would go far in making this a better world.
So rather than deleting or editing the ancient texts, they could be archived. Anyone referring to them when justifying their actions, particularly when it hurts someone else, would be responded to in such as way as to explain some of the "rules" that applied back then no longer apply in today's society.
