Mormonism and Christianity

Mormonism and Christianity have a complex theological, historical, and sociological relationship. Mormons express the doctrines of Mormonism using standard biblical terminology, and have similar views about the nature of Jesus' atonement, bodily resurrection, and Second Coming as traditional Christianity. Nevertheless, most Mormons do not accept the Trinitarian views of orthodox Nicene Christianity, codified in the Nicene and Nicene-Constantinopolitan Creeds of 325 and 381. Though Mormons consider the Bible as scripture, they do not believe in biblical inerrancy. They have also adopted additional scriptures, including the Book of Mormon, the Doctrine and Covenants, and the Pearl of Great Price. Mormons practice baptism and celebrate the Eucharist, but they also participate in religious rituals not practiced by traditional Christianity.

Focusing on differences, some Christians consider Mormonism "non-Christian", and Mormons, focusing on similarities, are offended at being so characterized. 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. Some view Mormonism a form of Christianity, but distinct enough from traditional Christianity so as to form a new religious tradition, much as Christianity is more than just a sect of Judaism.

The Mormonism that originated with Joseph Smith in the 1820s shared strong similarities with some elements of nineteenth-century Protestant Christianity. Mormons believe that God, through Smith and his successors, restored various doctrines and practices that were lost from the original Christianity taught by Jesus. For example, Smith, as a result of his "First Vision", primarily rejected the Nicene doctrine of the Trinity and instead taught that God the Father, His son Jesus Christ, and the Holy Ghost are three distinct "personages". While the largest Mormon denomination, The Church of Jesus Christ of Latter-day Saints (LDS Church), acknowledges its differences with mainstream Christianity, it also focuses on its commonalities such as its focus on faith in Christ, following the teachings of Jesus Christ, the miracle of the atonement, and many other doctrines.
