The flaw in monotheism is that ideals are not absolutes.

Truth, beauty, platonic forms are ideals.

The codes, creeds, heroes, narratives at the core of every society are ideals. Without this gravitational center, they would dissolve. Tower of Babel.

The universal is the elemental. 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 and animating the film, rather than the narratives playing out on it.

Ancient Israel was a monarchy. The Big Guy Rules. Like the religion.

Democracy and republicanism originated in pantheistic cultures. The young god, born in the spring, to the old sky god and the earth mother.

Though by the age of the Olympians, Zeus didn't give way to Dionysus. Tradition prevailed over renewal.

Which provided fertile ground for the story of Jesus.

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

Divine right of kings.

The origins of the Trinity shrouded by the Holy Ghost, as the Catholic Church is not about renewal, or women, for that matter.

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

Our technology might be evolved, but much of culture is still stuck back in the Bronze Age.

Tribalism trumps logic.
