The pen is mightier than the sword. And, the first casualty of war is the truth. Any Arabic warlord wishing to push back the tide of the "people of the book", or simply appropriate the apparent methods of their success, would, if aware of the two ancient maxims above, pick up a pen...first. First up, a backstory. Next, the actual story. Look how effective it's been. Memory is mightier than the sword only when a penman writes down what is supposed to have been remembered. In which case we can be told anything the penman wants us to think. Then, memory, or lack thereof, can be weaponized.
Back to the basics, Stoicism might be the ultimate answer! After more than 2,000 years of experiment trying something else. imo God = Nature = Reason = Fate = Universal Law = Everything = Cause = ... ...
imo, people know by nature which spoken or written words are true or not in their hearts inside, just being powerless for objection or counteraction during the difficult time span. Like the #MeToo moment! Perhaps the CC approach or something similar would provide empowerment for enacting Change! lol The kind of Change could not be accomplished by conventional physical weapons or forces that has been tried already for too long time! Leaving the weak and vulnerable ones alone in an environment without guided helps. Some become extremists!
Therefore, moderate believers can rely on the 'official comments' added in authorised holy books to counteract extremists' interpretations. https://elitetrader.com/et/threads/why-do-people-fear-death.307953/page-3#post-4439401
