Could the written material actually play a major role in what is stopping you from believing?
Far as I can remember, I always found belief in Gods to be akin to belief in Aesop's fables characters.
If that is good enough for you, then sure, it could be interesting to have some form of allegorical belief, as opposed to this exacerbated expectation that we have today, as a fully accepted component of religion.
But I don't think that would make for recognizable forms of the Abrahamics.
There are many ways the material could probably be different. In the bible there is an emphasis on war at times, and the morality can be quite ancient and severe. If alternatively, the bible was a pure doctrine of the best clear cut philosophical morals, with no parsing through metaphor and hard to understand riddle-like wisdom, would that make more of an impression on you.
Definitely. But that is an even greater departure from what Christianity is understood to be. Peter Singer and Derek Parfit would effectively be the best known "prophets" of our time.
What if it even contained science, perhaps conveyed to prophets, telling us how to produce the best medicines or engineer electrics cars the best way.
Such a radical departure from reality would probably require actual deities and make theism pretty much automatic. It would also have a very significant cultural impact, in ways that I have trouble trying to imagine. The very conception of morality would have to be quite different from ours.
Or organize cities and government most efficiently, in a manner that was straight to the point.
The knowledge for such is basically mastered already. The challenges are in the field of implementing it, in attaining the necessary mutual acceptance, motivation and cooperation.
To put it in another way: Civical and political organization are inherently hindered and limited by whatever social and cultural shortcomings happen to exist in any given culture and time. They are the expression of the exact form and level of collective insanity of that culture.
Do you think that some alternate scriptural text could help there? How so?
Instead, it obliges you to dig laboriously through ancient stories from the iron age like an archeologist. And from a long story of twists and turns arcane and hard to understand, you wrest from it what you believe is some relevant ingot of wisdom. But what if everything were crystal clear, with no twists and turns and controversy. With one simple testament relevant to all of modernity with principles clear as a mountain stream, with no need for clashing schools of interpretation and debate.
I think that you will eventually conclude that the difficulty of interpretation is a necessary component of what we currently recognize as religion. It makes possible for people who actually hold values and goals that are at odds with each other to nevertheless profess to be brothers in faith, mostly avoiding the realization that they should be apart.
In its current, mainstream forms, a major role of religion is precisely that of enabling such prolonged postponement of conflict by proposing other, more distanct and abstract goals and values.
Religion arguably must renounce that role of social engineering of dubious value, but that has its own drawbacks. If nothing else, it is a dramatic change that probably should be made gradually and carefully in order to avoid serious, destructive trauma.
It is not just a matter of getting people used to the shallowness of traditional scripture. Actual functional alternatives must be provided and developed. And for that to be possible, interpretation and debate, far from being a hindrance, are much necessary building tools.
