I'm sure you will get a massive flaming for the post but I think you probably have a point. I don't want to offend anyone with strong religious beliefs but if we just look at things objectively as you seem to have done it makes an interesting hypothesis.

Whether the people in the Bible were actually schizophrenics by clinical definition or not cannot be discerned but there are a lot of indications of at least transient psychosis and this applies to many religious traditions.

I sometimes jokingly tell people I have met Jesus and Satan and it was both times in a psychiatric hospital.

If any of the "prophets" or religious holy men who talked with God or saw angels were around today they would most likely be medicated long before they got to found a religion.

Also reading some of the extracts in your post made me think of something I heard somewhere -

"Forget Satan - God is by far the most evil character in the Bible."

So very true. Got is not fond of killing people in horrendous ways but he also expects them to follow a codes and rules which he breaks all the time. He also exhibits very human traits like anger, jealousy, vengeance etc.

He does sound more like a literal angry (human) king than an actual deity.
