Well, apart from the conflict that often occurs between religious believers, I suppose my other main gripe is as to them not changing as much as they might as we progress as a species, especially when so many simply rely on the written word.
Conflicts exist between everyone. Obviously there is a reason for that, although to most, the reason is not obvious.
What do you suppose is the reason for conflicts among scientists, and why are those not given the same attention, as the conflicts in religion.
Should a system that depends on empirical knowledge, not be one expected to be practically conflict free.
If one relies on principles to guide them, change is out of the question. Why? A principle is a fundamental truth. It doesn't change. It's an immovable foundation upon which everything else is built - laws, regulations, statutes, judgments...
This is the reason the instructions in the Bible are timeless, and why those who live by these are wise.
I'm sure if all the world were living by the Bible's guidance, the world's problems would be reversed.
Greed would end, solving problems like poverty and diseases. Honesty would be the only policy, ending economic loss, and distrust.
Jealousy would end, and infidelity would not exist.
Crime... including child exploitation and rape would not exist...
The only things rhat would not end, would be old age, sickness, and death, but maybe people would live longer, and for sure, be healthier - less heart problems, if any.
Oh, and hurricanes and earthquakes would still be around, but with everyone taking care of the environment, they would behave less violently.
So, clearly, the benefits of sticking to Bible standards are tremendous.
It would eliminate some of the junk science is used for.
Did you see North Korea's weapons? Well, that's not half the US', but consider the trillions of dollars being spent to accumulate junk on the earth... rather than feed and care for people's needs.
Not to mention, the chemicals from these, which contribute to the earth ecological health issues.
We cannot blame the written word for people who go contrary to it, though claiming to use it. Just as we cannot blame science for what people choose to use it for.
