Democracy and republicanism came from pantheistic cultures.

Greek religion originated out of fertility rites. 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.

So the story of Jesus, crucified for questioning power and risen in the spring, had fertile ground to take root.

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

When Rome adopted Christianity, 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. Providing the eschatological basis for the next 1500 years of European monarchy. Divine right of kings.

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

The logical fallacy of monotheism is that ideals are not absolutes.
