This is an interesting back and forth. May I offer up another view?
In my background as a generally agnostic Episcopalian, growing up on a farm, mostly race horses and cattle, religion was entirely a cultural issue, though a fairly deep one, given family history.
The cognitive experience of living in an extremely organic reality far exceeded the structural, logical and educational aspects of the Episcopal church.
As I see it, the basic logical fallacy of monothesim is that a spiritual absolute would be that essence of sentience, from which life rises, not an ideal of wisdom and judgement, from which it fell. Consciousness seeking knowledge, than any form or brand of it.
While science tends to be of the anthropocentric opinion that thought gives rise to consciousness, my experience is that it is the other way around. Recursive thought is simply a particular lens and filter through which this light of sentience shines, as all of life has multitudes of such forms of expression.
While the father figure lawgiver is a useful narrative device for instilling respect for authority and culture into a constantly re-generating population, conflating the ideal and the absolute has had serious deleterious effects on our ability to evolve beyond this stage.
As the ideal is aspirational, while the absolute is elemental, it has created the necessity for any movement seeking to supplant monotheism to make the same assumption, that ideals should be considered absolute.
From the Terrors of the French Revolution, to Stalin's purges, to the late stage capitalist obsession with the bottom line, to even current cancel culture, when ideals are at stage, nuance and debate are impermissible.
A good author on the foundations of Western culture is Gilbert Murray. Most famously for his; The Five Stages of Greek Religion.
One of the points that goes through his writing is that the Ancients were not totally ignorant of monotheism, but since there was no split between culture and civics, it was considered synonymous with autocracy and despotism. One God, one ruler.
It should be rememebred that more populist forms of governence, such as democracy and republicanism, evolved in pantheistic societies. Which were the original forms of multiculturalism, as tribal societies evolved into nationalist city-states and had to incorporate different deeply held customs.
Constantine adopted monotheistic Christianity as the official Roman religion, as it was solidifiying into an empire.
Remnants of the Greek year gods, essentially the symbolism of the cycling of the seasons, remained as the Trinity. God as Father, Son and Holy Ghost. Though the Catholic church, as the eternal institution, did its best to obscure the fundamental regenerative aspect of this. Consequently Luther tried pushing the reset button, as Jesus tried to do, with Judaism.
Another interesting author is Michael Hudson, whose most recent book delves into the economics of the Ancient world. One of the primary points he makes is that Jesus's dictum of "Forgive them their debts." really meant debts, as the practice of debt jubilees had been neglected for some centuries.
Though as the religion became co-opted by the powers that be, it then became, "Forgive them their sins." as a way to guilt trip people back into compliance with that divine ruler.
"Divine right of kings" became the default political model until the Renaissance. Though when the West went back to more populist forms of government, it required a separation of church and state, culture and civics.
Some of the conceptual mess leading up to where we are today.
