To understand what Mormons believe, one must examine their distinct theological framework centered on Jesus Christ as Savior and Redeemer, modern prophetic revelation, and an open canon of scripture. Members of the Church of Jesus Christ of Latter-day Saints believe God restored His ancient gospel, priesthood authority, and eternal covenants through Joseph Smith.
The Godhead: What Mormons Believe About God and Christ
The doctrine of God forms one of the most distinctive aspects of Latter-day Saint theology. While mainstream Christian traditions subscribe to the historic creeds formulated at Nicaea and Chalcedo—hich define the Trinity as one indivisible spiritual substance in three co-equal person—atter-day Saints hold a non-creedal, embodied understanding of the Godhead.
In Latter-day Saint doctrine, the Godhead consists of three separate, distinct divine beings: God the Eternal Father (Elohim), His Son Jesus Christ (Jehovah of the Old Testament), and the Holy Ghost. Rather than sharing an immaterial essence, the Father and the Son each possess physical, perfected bodies of flesh and bone as tangible as a human being's, while the Holy Ghost is a personage of spirit whose presence can dwell in the hearts of righteous believers. Despite their physical separation, these three divine persons are completely united in purpose, mind, divine perfection, and infinite love.
Jesus Christ occupies the absolute center of Latter-day Saint worship. Members revere Him as the Firstborn spirit child of God, the Only Begotten Son of the Father in the flesh, the Creator of the earth, and the divine Savior whose suffering in Gethsemane and death on the cross atoned for the sins of all humanity. Salvation is possible solely through the grace and merits of Jesus Christ. For an extensive theological examination of these contrasts, see our guide on Latter-day Saint and traditional Christian beliefs compared.
The Great Apostasy, the Restoration, and Living Prophets
A foundational element of LDS beliefs is the historical framework of the Great Apostasy and the subsequent Restoration. Latter-day Saints teach that following the death of Jesus Christ and His original apostles, ancient Christian communities lost the divine priesthood authority required to administer valid sacraments and govern the church. Over centuries, biblical doctrines were altered by Hellenistic philosophy and political compromises, resulting in the loss of original truths.
According to church teaching, God did not leave humanity without hope. In 1820, God the Father and Jesus Christ appeared to fourteen-year-old Joseph Smith Jr. in western New York, initiating the Restoration of all things. Heavenly messengers subsequently restored sacred authority: John the Baptist conferred the Aaronic Priesthood for baptism, while the ancient apostles Peter, James, and John conferred the higher Melchizedek Priesthood for spiritual blessings and church governance. This remarkable era is chronicled in our overview of the history of the Church of Jesus Christ of Latter-day Saints.
Because God's revelation did not cease in biblical times, Latter-day Saints believe in the principle of continuous revelation through living prophets. The President of the Church is sustained by members as a prophet, seer, and revelator, assisted by two counselors in the First Presidency and the Quorum of the Twelve Apostles. These leaders guide the global body through divine inspiration, adapting church administration while safeguarding doctrine. While the main body followed Brigham Young westward to Utah, other branches of the Restoration movement developed different governance structures, as seen in the history of the Community of Christ.
An Open Canon: The Four Standard Works of Scripture
Unlike traditions that affirm a closed scriptural canon, Latter-day Saints believe that God continues to speak through scripture. The church accepts four distinct volumes of sacred text, collectively known as the "Standard Works":
First, the church reveres the Holy Bible (using the King James Version for English-speaking congregations). Latter-day Saints read the Old and New Testaments as the inspired word of God, holding that the Bible serves as the historical bedrock of Christian revelation, accepted "as far as it is translated correctly."
Second, the Book of Mormon: Another Testament of Jesus Christ serves as a keystone scripture. Translated by Joseph Smith from ancient golden plates, the text recounts the spiritual history of prophetic civilizations in the ancient Americas from 600 BC to 400 AD, climaxing in the physical visitation of the resurrected Savior to the American continent.
Third, the Doctrine and Covenants contains a compilation of modern divine revelations and declarations primarily received by Joseph Smith and later church presidents, outlining priesthood offices, temple covenants, and organizational principles for the modern church.
Fourth, the Pearl of Great Price contains inspired translations and historical writings of Joseph Smith. This collection includes the Book of Moses, which expands upon early Genesis; the Book of Abraham, addressing the premortal council in heaven; an excerpt from Smith's inspired translation of the Gospel of Matthew; his personal historical testimony; and the thirteen Articles of Faith, which concisely summarize core beliefs on faith, repentance, baptism, spiritual gifts, and freedom of worship.
The Plan of Salvation, Eternal Families, and Sacred Temples
When analyzing Mormon beliefs about eternity, one encounters the Plan of Salvatio—lso called the Plan of Happiness. This comprehensive framework explains the origin, purpose, and eternal destiny of human existence.
Latter-day Saints believe that all human beings existed before birth as literal spirit sons and daughters of Heavenly Parents. Earthly life is understood as a vital probationary period, an educational school where spirits receive physical bodies, exercise moral agency, and learn through mortal trials. The Fall of Adam and Eve is not viewed as a tragedy, but rather as a necessary and deliberate step that enabled mortality and human progression, fulfilling the biblical purpose that "Adam fell that men might be; and men are, that they might have joy" (2 Nephi 2:25).
Following mortal death, the spirit enters the post-mortal spirit world, divided into spirit paradise for the righteous and spirit prison for those who died without knowledge of the gospel or lived disobediently. In the spirit world, the gospel is actively taught to those in spirit prison, ensuring that every person receives a fair opportunity to accept Christ. Through Christ's resurrection, every person who has ever lived will eventually be resurrected into an immortal physical body. Following the resurrection and final judgment, individuals will inherit one of three heavenly kingdoms or degrees of glory, symbolized by celestial bodies (1 Corinthians 15:–2): the Celestial Kingdom (shining like the sun, reserved for those who accept the gospel and keep its covenants), the Terrestrial Kingdom (shining like the moon, for honorable people who did not accept the fulness of the gospel), and the Telestial Kingdom (shining like the stars, for unrepentant individuals who lived wickedly).
The highest level of the Celestial Kingdom offers exaltation, where righteous husbands and wives continue as eternal families in the presence of God. This doctrine of eternal families is the driving purpose behind Latter-day Saint temples. In these sacred edifices, couples are married not merely "until death do you part," but "for time and all eternity" through the sealing power of the priesthood. In addition, members perform vicarious proxy baptisms and endowments on behalf of deceased ancestors, giving every soul who ever lived the opportunity to accept the gospel in the post-mortal spirit world. To understand how these structures differ from ordinary meetinghouses, review our analysis of Latter-day Saint temples and meetinghouses.
Christian Living: The Word of Wisdom, Tithing, and Lay Leadership
Latter-day Saint beliefs are deeply practical, requiring tangible behavioral commitments in daily life. One of the most famous lifestyle standards is the Word of Wisdom, a health code revealed to Joseph Smith in 1833 (Doctrine and Covenants 89). Church members abstain completely from alcoholic beverages, tobacco products, illegal narcotics, and "hot drinks," which prophetic revelation clarified as coffee and black or green tea. The revelation encourages wholesome grains, fruits, vegetables, and the moderate consumption of meat.
Financial stewardship is exercised through the biblical law of tithing. Members contribute ten percent of their annual income to the church. These funds support the construction and maintenance of thousands of meetinghouses and temples worldwide, finance the extensive missionary enterprise, fund church-owned universities like Brigham Young University, and provide global humanitarian relief through Latter-day Saint Charities.
Latter-day Saint life also emphasizes strict moral purity through the law of chastity, requiring complete abstinence from sexual relations before legal marriage and complete fidelity within heterosexual marriage. Women participate actively in church governance and community welfare through the Relief Society, established in Nauvoo in 1842, which ranks among the oldest and largest women's service organizations in the world.
Another distinguishing feature of the faith is its lay ministry. Local congregations do not employ professional salaried clergy. Instead, local congregations are led by unpaid, volunteer members called to temporary terms of service. Men and women lead worship, teach Sunday classes, oversee youth programs, and direct compassionate community service. To learn how local congregations are grouped and administered by volunteer leaders, read our guide on how Latter-day Saint wards and stakes operate.
Visiting a Latter-day Saint Congregation
Latter-day Saint meetinghouses are open to the public, and visitors of all faith traditions are warmly invited to attend weekly Sunday worship. Services center around the sacrament meeting, a reverent service where congregation members sing hymns, offer prayers, partake of the sacrament of the Lord's Supper (bread and water), and listen to sermons prepared and delivered by youth and adult members of the congregation.
