One of the main points he makes is that to the Ancients, gods were not so much metaphysical beings, but metaphors for the multitudes of conceptual aspects of life and reality. Which then solidified into those metaphysical beings, as they became conceptual foundations and all the social activities, festivals, rites, etc. developing the basis for societies and cultures. Carved into stone, so to speak.

To the Ancients, monotheism equated with monoculture. One people, one rule, one god.

Politically manifest as a form of autocracy. Ancient Israel was a monarchy. The Big Guy Rules.

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

The Christian Trinity originated out of fertility rites. The young god, born in the spring, to the old sky god and earth mother. Though by the age of the Olympians, Zeus didn't give way to Dionysus. Tradition prevailed over renewal.

Which is why the story of Jesus' crucifixion and resurrection had such fertile ground to take root in the first place.

Though by the time Constantine adopted Christianity as the state religion of Rome, it too had started to calcify, so the monotheism served to validate the Empire finally coalescing out of the ashes of the Republic. The Big Guy Rules.

So the Catholic Church served as the eschatological basis for European monarchy. Divine right of kings, as opposed to consent of the governed.

When the West went back to democracy and republicanism, it required separation of church and state, culture and civics.

The logical flaw in modern monotheism is that ideals are not absolutes.

Truth beauty, platonic forms are ideals. The core codes, creeds, heroes, narratives at the gravitational center of every culture are ideals.

The universal, on the other hand, is the elemental, so a spiritual absolute would be the essence of sentience, from which we rise, not an ideal of wisdom and judgement, from which we fell. The light shining through the film, than the stories playing out on it.

When one culture assumes their ideals to be absolute, none other can be tolerated. As we are seeing in certain religious wars.

Morality is not absolute, as it couldn't be transgressed, if it were. Like a temperature below absolute zero.

Morals are the ideals, the codes, behaviors, beliefs that enable a healthy and functioning society.

Traditionally that one's status and value a function of what one adds, not what one can extract. Which is why current culture is increasingly necrotic.
