hey Lisa,
I watched it last night - got a bit long (thus reaching my 25 spam limit for posts here).
From what I gather, the gist is that the concept of God started out as many gods, then started filtering down to the idea of a monogod, then came around again to a trinity god, then branched off to the Muslin concept, Budda concept, and a couple of other major religion concepts.
The name Yahweh I am that I am (they used something slightly different - but not "I will prove to be what I prove to be.") was given thought as to meaning - "It's really none of your business what my personal name is - it's enough that I'm your God and have power."
Thought that was pretty neat. Back then, persons would intone the names of their Gods in time of want, etc., and thought by knowing the God's name gave them some power over the God.
By Yahweh not giving a true name - but a poetic non-name - he remained untouched by man's perceived power.
And here we're discussing together - that's pretty neat also. Hope you're feeling better.
