1. The LXX existed, and was used by the first Christians, and the Holy Ghost was able to work, despite its corruption.
2. The LXX was used by the translators of the KJB, who knew it to be quite imperfect.
3. Presently, the LXX can be studied in light of the traditional Protestant view in relation to the King James Bible. There is very little place and use in ordinary study of the King James Bible doctrine for the Greek Textus Receptus, so likewise, how small an issue the LXX really should be.
4. Denying the traditional Protestant view of the LXX is unrealistic, unreasonable and foolish.
5. The modernist emphasis on the LXX is consistent with the spirit of error.

I think what has happened is when the modernists said something, that there has been an "ultra-conservative" resistance. The modernists said, the KJB has been revised, therefore it can be revised again. Of course, it would be wrong to have new revisions, but it is also wrong to then deny that any historical revision had taken place. Eventually, because there was a rejection of what the modernists stood for, everything that the modernists said became "wrong". When really the modernists were actually misinterpreting the facts, but in the minds of the ultra-conservative, the very facts themselves became suspect. (E.g. evolutionists said that dinosaurs lived millions of years ago, therefore my parents told me that there were no such things as dinosaurs.) This has happened with the LXX too. Because the modernists have the wrong interpretation does not mean that the base facts are wrong.
