CalebInFloroda, I have to say that I am totally confused and maybe you can help me.
Based on your comments it seems to me that you are saying that the Jews had a notion/idea/relationship with G-d (predating the OT) which, over time, was codified over time in the OT. And, that the OT reflects both cultural and religious ideas that cannot be well-understood let alone be used as a foundation for other religions because of the very specific and unique perspective (e.g. one needs to have the context of the Jewish religion and cultural history otherwise you end up with problems). If I got it wrong, my apologies.
However, I am still fuzzy on how ideas are reconciled. For example, how would you would address G-d's endorsement of mass genocide of men/women/children, slavery, stoning, and all sorts of things that we (as a society) and Jews would now find indefensible, immoral, etc.?
When you read those passages from the OT is your perspective "that was then, this is now"? Do you look at these acts as a reflection of the character of the G-d of the OT or is it strictly tied to the character of the people of the time?
I guess I am trying to better understand how you reconcile the G-d of the OT as it relates to some of the things you say. Thank you for your patience.
