Wouldn't a spiritual absolute logically be the essence of sentience, from which we rise, rather than an ideal of wisdom and judgement, from which we fell?

The fact we are aware, than the details of which we are aware.

Historically it would seem the premise of monotheism is monocultural. One people, one rule, one god.

Democracy and republicanism originated in pantheistic cultures, which metaphorically approximate multiculturalism.

The Romans happened to adopt Christianity as the Empire solidified and any remnants of the Republic were shed. The default political system for the next 1500 years was feudalism and monarchy. Divine right of kings.

When the West went back to more populist forms of government, it required the separation of church and state, effectively culture and civics.

While a father figure lawgiver might be an effective method of instilling group solidarity in a constantly regenerating population, equating the ideal, which is aspirational, with the absolute, which is elemental, seems to result in a culture that monolithically assumes one's ideals should be beyond reproach and debate, even when the original theistic premise has faded.

Knowledge and wisdom are earned, not ordained. Generally through much trial and error. Not all desires are healthy, nor all decisions wise, but life is finding that out.
