The Book of Mormon is an interesting scripture. The idea of tribes from Israel colonizing the New World has its challenges. The Bible itself tends to go silent about what happened to the northern tribes (“Israel” proper) after the exile. This opens the door to all kinds of possibilities. Various cultures have claimed to be the remnant. Native Americans, of course, tend not to apply the idea to themselves. As Givens points out, the Book of Mormon states that the Israelites of the New World died out long ago. Probably when the Latter-Day Saints are few centuries older, it may happen that metaphorical views toward the Book of Mormon might become prevalent. It took over a millennium before “mainstream” Christians began to ask some pointed questions about their own Scriptures.
Scriptures are products of their own periods. No matter how sacred or inspired they are thought to be, they were written down in human time and human space. Hints are often left along the way regarding authorship, origin, bias, and perspective. The Book of Mormon is rare in having a known publication date, and that in the nineteenth century. Autographs—original texts—are available, even if the golden tablets are not. It’s a rare opportunity to watch a scripture come into being. We know who wrote the Book of Mormon, and when. Its printing history is known, as is its context in the Second Great Awakening. All that’s needed are a few more centuries for scholars to see how things develop. Those who study scriptures are inclined towards the long view anyway.
