I’m afraid I haven’t read Karen Armstrong’s book, but I’m sure it’s pretty much in the same vein as a lot of other books I’ve read. I’m a big mythology and comparative religion fan.
Most religions which appear polytheistic have a very strong monotheistic impulse at their cores. Often, this is thought of as secret knowledge, or is something that shows up in important things like creation stories, and then fades into the background.
For example, most Native American religions are full of elaborate cosmologies and beings of various levels of power, but in the back of it all there’s a creator, or someone seen as running it all. Manito is a good example of this.
Hindus will often contend that their religion is basically monotheistic, and they have an argument. Depending on the part of India, the Big Deity tends to have different names, and they often elide them together into one big gloopy tons of incarnations Big Deity. But they see it as monotheism, and I’m not going to argue. This idea is not at all “recent”, from what I’ve heard about how far back this is found in Sanskrit texts.
In some ways, in fact, this idea that somebody was in back of all the other gods, running it all, allowed people not to worry about whether the mythological gods were worth worshipping. They might not be the sort of people you wanted running a universe, but it wasn’t them doing it. The real God was too busy and responsible to come into the stories.
