Church of Latter-day Saints: Beliefs, Name, Myths

The Church of Jesus Christ of Latter-day Saints and “Mormons” refer to the same faith, but members actively prefer the longer official name to emphasize Jesus Christ over a scriptural nickname. This distinction cuts through decades of media shorthand and addresses a formal church request issued in 2018 to retire the older label. Beyond terminology, the religion’s history, current practices, and global reach—including an unusual concentration in the Pacific island nation of Tonga—reveal a complex picture often obscured by outdated stereotypes.

Is there a difference between Mormon and Latter-day Saints?

The terms “Mormon” and “Latter-day Saints” refer to the same faith, but the church formally prefers the latter — and the distinction matters to members. The nickname “Mormon” comes from the Book of Mormon, a scriptural text members believe was translated by founder Joseph Smith from ancient golden plates. In 2018, the church’s governing bodies issued guidelines asking media and the public to use the full name instead.

Official name clarification

The official designation is “The Church of Jesus Christ of Latter-day Saints.” That name traces to a revelation Joseph Smith received on April 26, 1838, recorded in the 115th section of the Doctrine and Covenants. The church was originally organized on April 6, 1830, under the simpler name “Church of Christ.” By May 3, 1834, under the influence of church spokesman Sidney Rigdon, members adopted “The Church of the Latter Day Saints.” The hyphenated, full version standardized by 1851 remained in place after Brigham Young’s group consolidated leadership following Joseph Smith’s death in 1844.

Historical context

The church maintains that “Mormon” became widespread through decades of media and cultural usage rather than official adoption. A 2018 statement from the church’s First Presidency and Quorum of the Twelve Apostles noted that using the nickname had become “increasingly incomplete” as the religion expanded beyond its American roots. The instruction applied to internal communications, official websites, and public-facing materials — though informal usage persists in popular conversation and historical writing.

What does the Church of Latter-day Saints believe?

Members of the Church of Jesus Christ of Latter-day Saints identify as Christians who follow Jesus Christ and aim to restore original church organization and teachings from the New Testament era. The faith centers on prophetic authority in the present day, temple rituals, family-centered theology, and continued revelation through designated church leaders.

Core doctrines

• Faith in Jesus Christ as the Savior and Redemer
• Modern-day prophets who receive divine revelation for the church
• The Book of Mormon as additional scripture alongside the Bible
• Temple ceremonies including baptism for the dead and eternal family sealings
• Emphasis on personal revelation and direct communication with God through prayer

Jesus Christ focus

The church’s full name reflects a deliberate choice to identify itself by Jesus Christ rather than a book or historical figure. Church publications and official statements consistently reference the restored gospel and Christ’s role as central to all doctrine and practice. Members believe that Joseph Smith restored original Christianity after a period of apostasy, bringing back lost teachings about the Godhead, salvation, and temple worship.

Polygamy — or more correctly polygyny, the marriage of more than one woman to the same man — was an important part of the teachings of The Church of Jesus Christ of Latter-day Saints for a half-century.

Do Mormons share wives?

The practice commonly called “Mormon polygamy” refers to plural marriage — one man married to multiple women simultaneously. This practice was genuinely taught and performed by the church during the 19th century, but it ended over 130 years ago and is strictly prohibited today. The question still surfaces frequently because historical polygamy shaped both public perception and the church’s legal battles in the United States.

Polygamy history

Joseph Smith privately introduced polygamy in the 1830s, though the practice remained hidden from most church members until Orson Pratt publicly announced it at Brigham Young’s direction in 1852. During the public era from 1852 to 1890, estimates suggest approximately 20–30% of Latter-day Saint families participated in plural marriage, though exact figures remain difficult to confirm. The practice created significant conflict with the United States government, culminating in the Supreme Court case Reynolds v. U.S. in 1878, which ruled that religious duty could not override laws against polygamy.

Current practices

The modern church excommunicates any member found practicing polygamy on earth. Members who seek to join the church and currently practice plural marriage must abandon that relationship before receiving baptism. The church distinguishes itself clearly from fundamentalist groups that continue polygamous arrangements, stating these offshoots hold no affiliation with the LDS Church.

How many wives can Mormons have?

Current Latter-day Saint doctrine permits only one legal spouse. The church’s official position, restated multiple times through Church Newsroom articles and general conference addresses, is that monogamy is the standard for earth-life marriages. Polygamy is not required for salvation or temple ordinances in modern church teaching.

Modern policy

Members who enter temple marriage — called sealing — commit to one spouse for time and eternity under current policy. The church does allow temple sealings where one man may be “sealed” to multiple women if only one wife is living, though this reflects a doctrinal belief about the afterlife rather than permission for earth-based plural marriage. Church discipline for members who practice unauthorized plural marriage typically results in excommunication, removal of temple recommends, and loss of church membership.

FAQ responses

The church’s official FAQ and newsroom articles repeatedly address the polygamy question by emphasizing the complete cessation of the practice. Media inquiries about current polygamy are redirected to documentation showing the 1890 Manifesto, the official prohibition, and the excommunication policy for practitioners. This clear stance serves to distinguish the church from fundamentalist Mormon sects that remain in the American West and Canada.

What country is 60% Mormon?

The island nation of Tonga holds the highest concentration of Latter-day Saints relative to its total population. Estimates place the Mormon share of Tongan’s population at approximately 60%, making it an outlier in global Latter-day Saint demographics. No other nation comes close to this proportion.

Tonga church presence

The first LDS missionaries to Tonga — Brigham Smoot and Alva J. Butler — arrived on July 15, 1891, establishing a presence that would grow dramatically over the following decades. The Tongan Mission organized in 1916, coordinating church activities across multiple islands. Local members filled missionary roles during periods when international missionaries faced legal barriers from the Tongan government.

• First missionaries arrived July 15, 1891
• Tongan Mission organized 1916
• Approximately 60% of population estimates Latter-day Saint affiliation

The pattern of local members stepping into leadership roles during external restrictions created a resilient, homegrown church structure that continues to define Tongan Latter-day Saint identity today.

Global reach

Tonga’s unusual membership concentration stems partly from early missionary success combined with the country’s small population and limited competition from other Christian denominations. The church’s emphasis on family, education, and service resonates with Tongan cultural values, and local leadership development created sustainable growth even when outside missionaries were restricted.

LDS Church comparisons with other denominations

The Church of Jesus Christ of Latter-day Saints differs significantly from related religious movements that sometimes get conflated with it. Understanding the distinctions clarifies where the church stands on doctrine, current practices, and organizational structure.

Below is a side-by-side comparison showing how the LDS Church differs from the FLDS and Community of Christ on key doctrinal and organizational points.

Two comparisons stand out for clarity: the Fundamentalist LDS Church (FLDS) and the Community of Christ (formerly the Reorganized LDS Church, or RLDS). The FLDS continues practicing polygamy and maintains no affiliation with the main LDS Church — a point the church emphasizes when media coverage conflates the groups. Community of Christ, by contrast, rejected polygamy historically and currently maintains different theological positions on several core doctrines, including the nature of revelation and the role of modern prophets.

Those of us in Utah sometimes forget that people who don’t live here aren’t all that familiar with the Mormon church. The distinctions matter enormously when you talk about polygamous groups.

Latter-day Saints sincerely desired to be loyal citizens of the United States, but accepted plural marriage as a commandment from God — even as it brought them into conflict with federal law.
