Christians know that angels are a completely different order of created beings. Angels are angels and humans are humans. One cannot become another, in spite of the heartbreaking baby obituaries.
So, I respectfully invite you to explain the "angel" Moronoi whose gilded image is atop the spire of most LDS temples. I am confused. Your church teaches he was a man, son of Mormon, son of Nephi. Then he became an angel and appeared to Joseph Smith.
Maybe he was a ghost?
Well, I suppose this is another thing that you so rightly point out that people should investigate for themselves. I didn’t really expect you to defend this.
Huh? What version is that? Since there are nine versions of the first vision, is it like 1.1 or 1.9?
