And, of course, the Title Page of The Book of Mormon, which was part of the translated text says clearly it was written to/for Jew & Gentile & remnants of the Lehites, and all the House of Israel, etc. Not just to the LDS. The Bible is also for the whole world, not just those who will read it.This leads to several side issues, including: Who are the gentiles and how do they fit into the plan of regrafting? Who are the remnant, and how do they fit into the regrafting? Who are the Jews and how do they fit into the latter-day scheme? What about the latter-day saint practice of identifying a Tribe of Israel in the patriarchial blessings and the effect that has on regrafting?
These questions require a specific reference point from which to answer. The Book of Mormon and Doctrine and Covenants provide answers. In the vocabulary of both, the “gentiles” are the members of The Church of Jesus Christ of Latter-day Saints, and the unconverted European residents of “this land.” You should be able to see that for yourself just by reading the material. As a quick example, Nephi explains who the “gentiles” are in 1 Ne. 13: 14. Moroni explains who they are in the Title Page of the Book of Mormon written by him. Joseph Smith identifies the church as “gentiles” by identity. (D&C 109: 60.) We, the latter-day saints to whom the Book of Mormon was given, and who are among the very few readers of the text, are the “gentiles” of prophecy. Notwithstanding that status, there are many among the “gentiles” who have blood of Jacob in them. They are potentially candidates for restoration to the House of Israel. They are the intended targets of the restoration, but their restoration will not be completed until they are adopted back to the line of “the fathers” who are able to save them from the coming harvest.
So, to one of Underdog's points, not everything said by a Snufferite is from Snuffer - they tend to play telephone with some of the stuff he's taught.
