Mormons do not accept non-Mormon baptism nor do non-Mormon Christians usually accept Mormon baptism. Mormons regularly proselytize individuals actually or nominally within the Christian tradition, and some Christians, especially evangelicals, proselytize Mormons. A prominent scholarly view is that Mormonism is a form of Christianity, but is distinct enough from traditional Christianity so as to form a new religious tradition, much as Christianity is more than just a sect of Judaism
Joseph Smith said “that the Book of Mormon was the most correct of any book on earth, and the keystone of our religion, and a man would get nearer to God by abiding by its precepts, than by any other book,” (History of the Church, vol. 4, p. 461).
The LDS Church tries to make its official doctrines appear Christian but what underlies those Christian sounding terms is far from Christian in meaning.
