two churches only

The expression two churches only distills a central division in The Book of Mormon into a rule for sorting the world: people belong either to the church of the Lamb of God or to the church of the devil. Its force lies not only in the contrast between good and evil, but in the way it makes belonging decisive. Across the book’s histories of Mormonism and its fundamentalist descendants, that logic recurs in claims to exclusive religious truth, disputes over who has authority to govern, and the severe boundary drawn around those who leave.

Scriptural formulation

The Book of Mormon presents the division in categorical terms: “There are two churches only; the one is the church of the Lamb of God, and the other is the church of the devil; wherefore, whoso belongeth not to the church of the Lamb of God belongeth to that great church, which is the mother of abominations.” The statement leaves little room for a morally neutral position. A person’s place in the world is defined by allegiance, and the alternative to the true church is not simply another denomination but the opposing camp in a struggle between good and evil.

That starkness is part of the appeal the book describes. Joseph Smith taught converts that the Church he restored was the only true and living church, while Christianity beyond its origins had been led astray in what he called the Great Apostasy. The Book of Mormon was presented as a corrective account of sacred history and a restoration of the true Church of Christ. Its two-camp formulation gave that claim a simple structure: a complicated religious landscape could be read as a choice between truth and error, rather than as a field of competing interpretations.

The book also situates this certainty in an American sacred geography. The Book of Mormon’s history unfolds largely on the American continent; Jesus Christ visits the New World after his resurrection, and Joseph Smith’s revelations locate sacred events and the promised return of Christ in America. The resulting picture joins religious identity to a chosen people and a promised place. The binary is therefore more than a description of belief: it helps define who belongs to a divinely favored community and what that community believes it is entitled to claim.

From religious boundary to social conflict

The same division acquired political consequences as Mormon settlement expanded into Jackson County, Missouri. The Saints regarded themselves as God’s chosen people and the region as their divinely granted Zion. Many local residents, already uneasy about the newcomers’ abolitionist sympathies, were further alienated by the Saints’ communal separation, collective voting, and purchase of substantial land. In the book’s account, the conviction that the Saints occupied the righteous side of a sacred divide sharpened the conflict between their claim to a promised inheritance and the objections of people who already lived there.

The rhetoric of choice could also make disagreement appear morally conclusive. Joseph Smith taught that people were free to choose between the Lord and wickedness, but that those who knowingly rejected the Saints’ God were undeserving of sympathy or mercy. A revelation described Missouri as the Saints’ inheritance and as the land of their enemies; a Mormon newspaper’s promise that the wicked would be destroyed deepened local fears. The idea of two opposed churches did not by itself explain every cause of conflict, but it offered a powerful framework in which outsiders’ resistance could be interpreted as hostility to God’s people.

Competing authorities and laws

In Nauvoo, the division between the sacred community and the outside world met a practical question of government. The Illinois charter gave the city unusual sovereign powers, and Joseph Smith stood at the head of a theocratic principality, with the Nauvoo Legion under his command. The church’s claim to religious authority thus existed alongside civic institutions and military power; the boundary between religious community and surrounding society was also a dispute over who could make and enforce rules.

The same problem became explicit under Brigham Young in Deseret. He argued that God’s laws took precedence over human laws, particularly when those laws came from non-Mormon authorities. The Utah Territorial Legislature, dominated by Mormons, enlarged the jurisdiction of probate courts controlled by Brigham Young. Mormon bishops often served as judges, and church members made up most juries. Federal officials complained that the territory had become a theocratic dictatorship, while many local leaders treated religious law as the higher authority. Here the two-camp outlook did not simply distinguish believers from unbelievers; it helped sustain a rival account of which law deserved obedience.

Later claims about the right to practice plural marriage show that the boundary could also be contested in the language of civil liberty. Sam Roundy, Colorado City’s police chief, maintained that private religious practice was no one else’s business, while the book notes that plural marriage was illegal throughout the United States and Canada. This juxtaposition complicates any simple division between a unified religious community and an irreligious state: believers could appeal to constitutional protections even as their religious order asserted claims that conflicted with state law.

Reappearance in fundamentalist communities

Among Mormon Fundamentalists in Colorado City, the division takes an intimate form. The book describes restrictions on television, newspapers, magazines, and contact with people outside the United Effort Plan, including relatives who had left the faith. Television dishes sometimes reappeared in secret after a sermon by Rulon Jeffs condemned them; members then discarded the dishes, and the prohibition would hold for a time before the cycle began again. The pattern shows how a boundary against the outside world could be enforced through rules and warnings yet remain vulnerable to ordinary desires and private disobedience.

Departure carried more serious consequences. When DeLoy Bateman decided to leave the Work, Rulon Jeffs arranged for his wives and children to be reassigned, in keeping with the doctrine that they belonged to the priesthood rather than to their husbands or parents. Both wives refused to leave DeLoy, and they and most of the children became apostates with him. The episode makes the social meaning of the divide concrete: leaving did not merely alter a person’s stated belief but changed that person’s standing within a community that controlled family relationships. Warren Jeffs later described an apostate as profoundly evil and aligned with Lucifer, language that placed the dissenter on the condemned side of the same absolute division.

Dan Lafferty’s religious-political discussions provide another later echo. He argued that government had exceeded its proper reach, using scripture to challenge requirements such as licenses, taxes, and Social Security numbers. His self-directed study led him to reject the modern Church of Jesus Christ of Latter-day Saints as having abandoned plural marriage under government pressure. In this account, the opposition between fidelity and betrayal extends beyond a division between churches: institutional accommodation to civil authority can itself be treated as evidence that a religious body has left the true path.

Meaning and limits of the expression

The book presents the two-church formulation as a durable way of making identity morally legible. It links the promise of an intimate relationship with God to an equally sharp account of those outside the faithful community. In different settings, that contrast can support missionary certainty, communal solidarity, resistance to outside authority, or the condemnation of dissent. Its effects depend on the institutions and practices that give the distinction force: settlement and political organization in Missouri, courts and territorial government in Utah, or restrictions on information, association, and family membership in Colorado City.

The expression does not make every conflict identical, nor does the book reduce Mormon history to a single doctrine. Its significance is that it supplies a recurring pattern: a community understands itself as chosen, its opponents as morally opposed, and disagreement as a question of allegiance rather than merely a difference of judgment. In that pattern, the boundary can make collective purpose vivid, but it can also make compromise difficult and departure costly.
