Mormons self-identify as Christian, but some non-Mormons consider Mormons to be non-Christian because some of their beliefs differ from those of mainstream Christianity. Mormons believe that Christ's church was restored through Joseph Smith and is guided by living prophets and apostles. Mormons believe in the Bible, as well as other books of scripture, such as the Book of Mormon. They have a unique view of cosmology and believe that all people are literal spirit-children of God. Mormons believe that returning to God requires following the example of Jesus Christ, and accepting his atonement through repentance and ordinances such as baptism.
