To quickly research a little on this embarrassing issue for my church see http://scriptures.lds.org/en/jst/contents, http://scriptures.lds.org/en/3_ne/12, http://scriptures.lds.org/en/3_ne/13, http://scriptures.lds.org/en/3_ne/14, http://scriptures.lds.org/en/matt/5, http://scriptures.lds.org/en/matt/6, and http://scriptures.lds.org/en/matt/7.
So basically either the Book of Mormon is wrong and/or the Joseph Smith Translation of the Bible is wrong. They both can’t be right. This is most certainly a big problem for the Church of Jesus Christ of Latter-day Saints of which I’m a member and High Priest. The best thing for us to do is to repent and apologize for Joseph Smith and his lunacies.
