- Do you see this progression in the Bible, or do you interpret it differently?
Yes. I speak for myself only. I think the earlier texts in the Bible were basically indicative of a belief in many gods, "but YHWH is OUR god," so to speak. In otherwords, by the time the earlier parts of the Bible were written, Israel had moved from polytheism to henatheism. Not perfectly. The inclination to revert to polytheism was still strong so there were many lapses.
But something happened in Babylon. Normally, if a people were conquered, they would think, "I guess their god is greater than our god, so let's start worshiping their god." But that's not what the Jews said. For reasons that I have no idea, they said to themselves, "The God of Israel is the God of the whole world, including Babylon. It's not that Marduk is stronger, but the YHWH is using Babylon to discipline us for our idolatry, violence, and neglect of the poor.
THAT was the turning point in history.
That's when Jewish literature began including things like, "I am the LORD your God, and beside me there is no other." You had stories like Elijah laughing at the vain attempts of the priests of Baal to have their sacrifice divinely set on fire. Indeed he mocks them. "Maybe your god is relieving himself." IOW, its not that Baal is less powerful than YHWH, its that Baal does not exist. The extended version of Daniel has a very similar story. Daniel is like a Jewish Sherlock homes who reveals Bel doesn't NOT eat the sacrifice, that it is the priests enter the temple at night to eat the sacrifice. In other words, Bel is NOT REAL.
Since Babylon, idolatry has not even been a temptation for Jews. Not just for us. The Pharisees spread monotheism throughout the Roman empire. 10% of Roman were Jews, and that's not including the God-fearers.
When the new religion of Christianity formed, it built on Jewish monotheism. Same with Islam 600 years later.
Today, even people who are not part of any organized religion share the idea that there is one God, the creator, who is God of all the world.
- What factors do you think contributed to the rise of monotheism in various cultures?
I think it simply makes more sense. This is largely because monotheism has a single coherent morality. How is one supposed to be morally consistent if one worships the god of love on Monday, and the god of war on Tuesday.
I think that something that aided the spread was the willingness of the monotheistic religions to adapt to different cultures. By adopting traditions of those cultures, monotheism became more palatable and relevant to the population. I think most people are familiar with how Christianity adopted things like the use of evergreens and wreaths and gift giving at Christmas.
- How do you think this historical shift impacts modern religious beliefs and interfaith dialogue?
Well, it's a heck of a lot easier to dialogue if one can build on the foundation that there is one God.
One of the things that came into existence along with monotheism was the idea that God cares about how we treat each other. So people of different monotheistic faiths can join hands in addressing societal issues such as hunger and poverty, racism, etc.
