Within the Latter Day Saint movement, Zion is often used to connote a utopian association of the righteous. This association would practice a form of communitarian economics called the United Order meant to ensure that all members maintained an acceptable quality of life, class distinctions were minimized, and group unity achieved. While Zion has often been linked with theocracy, the concept of Zion did not theoretically require such a governmental system. In this way, Zion must be distinguished from the ideal political system called theodemocracy which Mormons believed would be adopted upon Christ's Second Coming. However, "Zion" maintains several possible meanings within the Latter Day Saint lexicon.
In one interpretation, Zion refers to a specific location to which members of the millennial church are to be gathered together to live. Stipulated by what is believed by the Latter-day Saints to be the revelation of Joseph Smith (D&C 57:1–5, LDS Church ed.), this is said to be located in Jackson County, Missouri, and its county seat, Independence. The region of Kansas City Metropolitan Area remains important today in the doctrine of The Church of Jesus Christ of Latter-day Saints (LDS Church) and the Community of Christ, as well as many smaller branches and offshoots of the Latter Day Saint movement, who view it as having a crucial role to play in their Christian Millennialist theology.
The word "Zion" appears 53 times in the Book of Mormon, a key part of the Latter Day Saint canon, and 268 times in the LDS Church's version of the Doctrine and Covenants, a part of its canon consisting of what members believe to be modern-day revelation and written down by Smith mostly in the 19th century. Following the disappointments and strife which took place in Missouri during initial attempts to establish a "City of the Saints" in the region, the concept of Zion evolved to encompass a less geographically-specific idea similar to the orthodox Christian concept of the "ekklesia" (See Ecclesia (Church)) or community of believers regardless of location. This concept is hinted at in such scriptural passages as the following: "Therefore, verily, thus saith the Lord, let Zion rejoice, for this is Zion—THE PURE IN HEART; therefore, let Zion rejoice, while all the wicked shall mourn."
