John A. Tvedtnes addresses charge Book of Mormon is anachronistic due to its use of the Old Testament and understanding of the Old Covenant.
John A. Tvedtnes, "Wesley P. Walters, The Use of the Old Testament in the Book of Mormon," Review of Books on the Book of Mormon 4, no. 1 (1992): 220-34
Conclusions
Though issued under the guise of scholarly research, Reverend Walters's book is not a serious attempt to study the use of Old Testament passages in the Book of Mormon. as its title suggests. Rather, it is a biased and clearly negative view of Joseph Smith and his work. While it raises a few new questions, most of it is a rehash of what other critics of the Book of Mormon have already said. If there is one good thing about books like this, it is that they prompt us to study the Book of Mormon even more, in order to get at the truth of the matter.
