I found this Article in the Salt Lake Tribune about a wording change in the introduction to the Book of Mormon. It is a potentially groundbreaking change that has not happened in my adult lifetime. In many ways, I'm stunned and interested in the long term effect of this change in wording.
It opens the door for a shift in Mormon theology, by attempting to reconcile it to modern scientific theories. The significance of the change has to do with the ancestry of Native Americans--is that ancestry accurate as the Book of Mormon describes or has DNA and other archaeological evidence proven otherwise? The video below is about a 50 minute documentary of some of the difficulties for the history of America presented in the BoM.
The alternative of this kind of change that could prevent L-D-Saints from totally allegorizing the text, or totally abandoning it's historicity, or completely undermining the truthfulness of Joseph Smith.
To make a comparison, for me, it would be akin to all the archaeological, linguistic, and other evidences validating some Islamic claims that the Jews never occupied nor ever built a temple in Jerusalem--for that matter, ever lived in the territory called Palestine.
Like I said, it will be interesting to see how this plays out and how it affects the rank and file Mormon believer. If anyone reading this is Mormon, I would appreciate any insights into your thinking as well as encourage you to see the video.
