I have all three of David Sorenson's books on the version issue. I recommend them. I also have a book by Metzger on the other side of the issue.
Sorenson is a good man, I've been told, though I don't remember ever meeting him, so I can't say for myself. I only have one of his books,
Touch Not the Unclean Thing, but I read it carefully and have some bones to pick with him. Overall he does a pretty good job, though I think he blows it with Westcott and Hort (as do many KJVO authors) setting up straw men which cannot be defended. I do have the W&H Greek NT from 1886, and have read some of their other stuff. I believe them to simply be the product of their times, normal Ch. of Eng. men. It does the KJVO side no good to misrepresent them as many of them do. They were not theological liberals, and they did not believe in spiritism. (Unbelievably, Sorenson quotes Riplinger about this on p. 171.)
Back to Sorenson, I very strongly object to the subtitle of the mentioned book: "The Text Issue and Separation." He writes at the end of the book, "A thesis of this writer is that the critical text is unholy through its manifod associations with apostasy" (p. 224). What this means to Bibliology is that humans can weaken and make unholy God's eternal Word. I object to this with every fiber of my being.
If you quote John 3:16 in the pulpit, but leave out a word, have you weakened the Bible? 1000 times no! If you are translating into a foreign language, and accidentally leave out a phrase or even a verse (I have done this), is your translation then powerless? Not in a million years!!!
My problem with many of the books mentioned above is that they use shallow arguments to defend the KJV. The KJV can be defended scholarly without resorting to taking verses out of context.
This I agree with. Personally, I don't see the need to defend the KJV. (Nor should we attack it.) It's a sword, and as I tell my students, you don't defend a sword, you take it out and stab someone with it! Let's preach the Word of God and forget Sorenson's position of ecclesiastical separation with other good men who disagree with our position.
