The basic logical fallacy in monotheism is that ideals are not absolutes.
Truth, beauty, platonic form are ideals. The core codes, creeds, heroes, narratives at the center of every society are ideals.
The universal, on the other hand, is the elemental. So a spiritual absolute would be the essence of sentience, from which life rises, not an ideal of wisdom and judgement, from which it fell.
The light shining through and animating the film, than the narratives playing out on it.
To the Ancients, gods were what ideals, metaphors, memes are today. In that world, monotheism basically meant a monoculture. One people, one rule, one god. The formative experience for Judaism was the forty years in the desert, giving rise to the Ten Commandments, as a code for a functional society. Basically the tribe, the human herd, as a larger super organism.
The significance of the New Testament is encapsulated in the Golden Rule; Mathew, 7:12, Do unto others, as you would have them do unto you.
Basically civilization had to move beyond that Bronze Age tribalism as a defining model, as the various tribes began to more fully integrate.
