That's a bit of reverse engineering.

To the Ancients, the concept of gods amounted to ideals, metaphors, memes.

It wasn't so much a pre-scientism, as those conceptual units of thought and conversation. Gods of war, love, seas, sun, fertility, rivers, mountains. Their essence, as expressed as a concept. Like Rodin's The Thinker might be an idealization of contemplation.

To this stage of cognitive evolution, monotheism equated with monoculture. One people, one rule, one god. Usually politically manifest as monarchy. The ruler as expression of the group. Sort of like the mind is the focal point of the emotions. Ancient Israel was a monarchy.

To the Ancients, the most basic element of life was the cycling of the seasons and nature renewing itself. Formulated as the young god born in the spring, to the old sky god and earth mother. Though by the age of classical Greece and the Olympians, Zeus didn't give way to Dionysus. Tradition prevailed over renewal. The old didn't make way for the young. Which is a basic tension throughout time. This is the source of the Christian Trinity and why the story of the resurrection of Jesus had such fertile ground to take root.

Democracy and republicanism originated in pantheistic cultures. The many ideas and ideals interacting.

Constantine adopted Christianity as he was bringing the Empire back together, basically for the monotheism, to validate rule from above. Divine right of kings, as opposed to consent of the governed.

While the origins of the Trinity where shrouded by the Holy Ghost, as the Church didn't do renewal, or women.

Making the Catholic Church the eschatological basis for European monarchy. When the West went back to democracy and republicanism, it required separation of church and state, culture and civics.

The logical fallacy of classic monotheism is that ideals are not absolutes. The universal is the elemental, not the ideal. 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 and animating through the film, not the stories playing out on it.

The consequence is now that everyone feels compelled to assert their ideals as universal and beyond question, while all others are flawed.
