Thanks for an introduction to those two terms. I don’t think I am talking about either of them. If monolatry is “the worship of one god without denial of the existence of other gods”, and henotheism is “adherence to one particular god out of several, especially by a family, tribe, or other group”, [definitions found online], then they mean something very similar. That would be worship of one god within a polytheistic system of many gods. I am certainly not advocating that, rather pointing out that ‘gods’ [note lower case] are at a different, lower level than what we call God. A better term should be used to avoid confusion arising from using the same word.

Do you believe in angels?

I note that you believe that Yahweh was promoted to preeminence. This presumably means that this was a later development, therefore a decision by humans at some point, therefore possibly open to error.
