Spike,
I can understand that you would think that the "Is the name YHWH in the New testatment" makes the most sense, because it says what you have said before, but id doesn't prove it.
Now, that siad, like I have mentioned before, the use of YHWH in the NT in regards to OT passages that are being quoted is something that NO ONE argues with, if of course the tetragrammaton was there to begin with and IF it does NOT change the context of the passage/verse/chapter.
That is truly the big issue more than any other.
Also, the continued reference to the passges that mention the word "NAME" or show Jesus saying the word "NAME" don't ADD to your argument because, as we know NAME has far greater meaning than the actual name AND because Jesus Says the word NAME and DOES NOT say the actual NAME !
