Dear Earnest,

"So whether you wish to call it a conspiracy or not, we clearly have a case for the universal removal of God's name from scripture by the Christians without any record outside of the LXX copies themselves that such a procedure had taken place. It is a very small leap to believe they did the same to their own writings."
This LXX analogy will not work, I think, for the following reason: we do have external evidence for the LXX rendering the Divine Name as YHWH (with Hebrew letters) rather than Greek "kurios". No such evidence exists for the tetragrammaton ever being in the so-called NT. I think this is very important.
If we stick to the "hard evidence", the following two scenarios seem likely: either (a) the Christians started to write the "qere" (i.e. "kurios") when copying the LXX because they found the "qere" in the OT quotations of the NT; or (b) the Christians used "pre-kaige" versions of the LXX with "kurios", not the tetragrammaton. (Note: Howard too thinks that Greek speaking Jews/Christains uttered "kurios" when they saw "YHWH".) As we have at least two possible scenarios supported by the evidence, why opt for an unsupported theory -- if not according to some theological bias?
One should also note that it is not always possible to distinguish Christian and Jewish copies/versions of the LXX/OG. There are scholars, more distinguished than Howard, who would argue that some Jews also had "kurios" instead of "YHWH" in the LXX.
