耶稣基督后期圣徒教会（英文名称The Church of Jesus Christ of Latter-day Saints，前称耶稣基督末世圣徒教会）单从其特意以耶稣基督的名字为其教会的命名可知，在信仰基础上与基督教新教有南辕北辙的分别。基督新教各教派的领袖们，为避免自己教会内的信徒混淆，又因它是摩尔门经版权的唯一持有者和用户。一致同意使用摩尔门教（Mormon Church）这个非法定的名称予以区分。其英文简称LDS即Latter Day Saints的缩写，中译“后期圣徒”。该教会认为其运作模式，是遵从圣经新约内所记载的耶稣基督从犹太民族中复兴的教会别无二误，也是祂教会的延续。

The Church of Jesus Christ of Latter-day Saints (the LDS Church or, informally, the Mormon Church) is a Christian restorationist church that is considered by its followers to be the restoration of the original church founded by Jesus Christ. The church is headquartered in Salt Lake City, Utah, and has established congregations (called wards or branches) and built temples worldwide. According to the church, it has over 74,000 missionaries and a membership of over 15 million. It is ranked by the National Council of Churches as the fourth-largest Christian denomination in the United States. It is the largest denomination in the Latter Day Saint movement founded by Joseph Smith during the period of religious revival known as the Second Great Awakening.
