Oh I wish. Its been many years since I got to fight in an SCA battle.
The Qumran and the Masada scrolls show that the Old Testament text was still not stabilized near the end of the first century AD.
One of the many things I am not an export on are the dead sea scrolls. However, from everything I do know, your conclusion sounds pretty zany. So I googled it, and found tons of dull dry info that gave me no relevant insight before I ran out of patience.
So I must ask, do you have a source you can point that lends support for this non stabilization.
As for asking who I am arguing with. I make it a habit to try to refine and/or correct my views to be more in line with truth. Since I believe it is truth that sets us free. So any argument that you have made that seems it might have merit, I have tried to consider. So far I think you make a much worse case for naturalism then I had already made for myself...and not found as convincing as that for Christianity.
Sorry if some of that arguing with myself spilled over. I think we all do that a little...or it at least I would like to think that.
