This chapter examines the central teachings and organizing concepts of Latter‑day Saint theology as lived and taught in the tradition, and it contrasts those claims with lines of scholarly interpretation where they diverge. The account foregrounds the tradition's self‑understanding — revelation, scripture, cosmology, and soteriology — while indicating internal variety and contested topics.
A distinctive theological hallmark is the conviction of continuing, open‑ended revelation. Adherents hold that God speaks to prophets and that authoritative revelations continue to come to a modern prophetic office established in the church. This conviction is institutionalized in a canon that, in addition to the Bible, includes the Book of Mormon (first published 1830), the Doctrine and Covenants (a collection of recorded revelations received by Joseph Smith and others, gradually compiled in the 1830s and afterward), and the Pearl of Great Price (a compilation of materials including selections attributed to Joseph Smith and others, canonized later in the nineteenth century). The presence of multiple volumes situates the tradition as explicitly restorationist: it claims to restore lost priesthood authority and to provide new scripture intended to guide the modern church.
Central doctrinal concepts revolve around the nature of God, the human condition, and the goal of exaltation. Latter‑day Saints teach that the Godhead consists of three distinct personages — God the Father, His Son Jesus Christ, and the Holy Ghost — a theology that differs from classical Nicene Trinitarian formulations. Adherents describe God and the resurrected Jesus Christ as embodied, perfected beings, and they emphasize a plan of salvation that begins with pre‑mortal existence. The doctrine of a pre‑earth life — the belief that human spirits existed with God before mortal birth — is a prominent element in popular and formal teaching. Within that framework human life on earth is an opportunity to exercise agency, receive a mortal body, and pursue moral progression.
The telos of religious life in the tradition is frequently described as exaltation or eternal progression: the possibility that individuals, through covenant keeping, ordinances, and obedience, may become heirs of divine glory and enjoy familial relationships beyond death. Temples and temple ordinances (explored in more detail in the chapter on ritual) are central to this soteriological horizon, particularly the sealing ordinances that bind families 'for time and all eternity.' The emphasis on family and intergenerational continuity — and on vicarious ordinances performed for the dead — is distinctive and has shaped institutional priorities such as genealogical work.
Ethics and daily conduct flow from these theological convictions. The law of consecration, tithing, and the Word of Wisdom (a health code first published as a revelation in 1833) are examples of teachings that regulate personal and communal life. The Word of Wisdom proscribes tobacco and recreational alcohol, and leaders have long interpreted its injunctions to include avoidance of coffee and tea; it also commends moderation and the use of wholesome foods. The centrality of family life — expressed through slogans such as 'family is central to God's plan' in contemporary discourse — shapes policies on marriage, child rearing, and social support.
Sacramental and covenantal language is pervasive. Baptism by immersion is required for membership, typically performed after an 'age of accountability' set at eight years. Baptism is followed by confirmation and reception of the gift of the Holy Ghost. Throughout life adherents participate in ordinances that mark progression and belonging: ordination to priesthood offices (for males), temple endowment, sealing ceremonies, and sacramental participation in weekly worship. These practices reinforce a covenantal anthropology in which obligations and divine promises are reciprocally bound.
On scripture and authority there is an enduring tension. Adherents treat the Book of Mormon as another testament of Jesus Christ and as historical narrative of ancient American peoples; historians and textual scholars debate questions of historicity, sources, and composition. Likewise, the Doctrine and Covenants contains texts that record the institutional formation of the movement; textual critics examine different manuscript traditions, reception history, and editorial processes. The result is a field in which believers often rely on devotional readings and faith‑promoting interpretations, while historians subject the same texts to philological, archival, and comparative methods.
Another notable theme is the ecclesiology of priesthood. Latter‑day Saints understand priesthood as divine authority conferred by laying on of hands; they distinguish between the Aaronic Priesthood (whose offices include deacon and teacher) and the Melchizedek Priesthood (including elders and high priests). The exercise of priesthood authority — for blessing, ordaining, and performing ordinances — is central to communal life and marks an institutional difference between Latter‑day Saint polity and many Protestant bodies.
Belief is not monolithic within the movement. There is substantial internal diversity. Some adherents hold conservative devotional positions emphasizing prophetic pronouncements and literal readings of scripture; others adopt more liberal or interpretive approaches that integrate modern biblical criticism, historical scholarship, and contemporary ethical reappraisals. Issues such as the role of women in ecclesiastical leadership, interpretations of the spiritual meanings of temple ordinances, and approaches to LGBT persons are examples where wide variation in belief and practice is evident across national and generational lines.
Comparatively, the movement can be read as both continuity with and departure from broader Christianity. It claims continuity through its explicit identification with Jesus Christ and by publishing a text titled The Book of Mormon that attests to Christ. Yet many mainstream Christian denominations contest whether Latter‑day Saints share essential creedal commitments, largely because of divergent doctrines about the nature of God, revelation, and the possibility of human deification. Scholars navigate this tension by treating the tradition as a distinct branch within the Christian family: restorationist in impulse, scripturally expansive in corpus, and institutionally oriented toward ordinances and prophetic authority.
In sum, the worldview of Latter‑day Saints centers on continuing revelation, an expanded scriptural canon, a plan of salvation that includes pre‑mortal life and exaltation, and an ethic keyed to covenants, family, and bodily sanctity. The interplay of devotional certainty and scholarly inquiry produces a dynamic field: adherents cultivate faith through ritual and revelation, and scholars analyze those convictions as historically situated doctrinal developments.
