"Mormon" Doctrine Plain and Simple
Leaves from the Tree of Life
Charles W. (Charles William) Penrose (1832–1925)
This collection serves as a direct, nineteenth-century exposition of the theological foundations and ecclesiastical structures of the Church of Jesus Christ of Latter-day Saints.
In Short
This volume acts as a primer on the core beliefs of the Latter-day Saints as understood in the late nineteenth century. It outlines the necessity of divine authority, the process of salvation, and the hope for a future where families are reunited and perfected in the celestial kingdom. By framing religious life as a "science" of human redemption governed by immutable laws, it provides a structured defense of the faith against contemporary critics, articulating a worldview that centers on the restoration of ancient prophetic practices and the ultimate exaltation of the human race.
The Story
The narrative arc of the book follows the progression of a human soul from mortal life through the resurrection and into the various spheres of eternal glory. It begins by establishing the necessity of truth and the fundamental requirement of a direct, divine commission to act in God’s name. The author argues that religious truth is not a matter of human invention but a discovery of laws established by the Creator. He traces the history of the "Church of Christ," explaining its ancient origin, its subsequent apostasy after the death of the apostles, and its eventual restoration through Joseph Smith.
The text then shifts to the mechanics of entry into this restored kingdom. It details the essential "first principles"—faith, repentance, and baptism—as the necessary steps to cleanse the individual. This is followed by the "laying on of hands," which confers the Holy Ghost and integrates the believer into a living, organized body. The author emphasizes that this is not merely a symbolic process but an actual, authorized administration of divine power, often referred to as the Priesthood.
As the scope of the argument widens, it moves beyond the living to address the fate of the deceased. The author posits a wide-reaching vision of mercy, wherein the gospel is preached to spirits in prison and vicarious ordinances are performed by the living for their ancestors. This bridges the gap between the mortal and the spiritual realms, suggesting that God’s plan is universal and that the family unit, if properly sealed, continues into eternity.
The climax of this theological journey is the description of the resurrection and the three degrees of glory—Celestial, Terrestrial, and Telestial. The author depicts a cosmic hierarchy where every individual eventually finds a place according to their capacity and conduct. The final sections move toward the ultimate triumph of the Latter-day Kingdom, which the author envisions as a "theocracy" that will eventually replace the fractured political and social systems of the earth. The book concludes with a vision of a future state where, under the reign of Jesus, the earth itself is glorified and linked to the celestial order of worlds. It is an argument for a complete, structured cosmic cycle that begins in a fallen, mortal state and ends in the perfection and eternal dominion of those who have faithfully adhered to divine law.
How It Unfolds
The quest for authority The work opens by distinguishing the Church of Jesus Christ of Latter-day Saints from the general label of "Mormonism." It insists that valid religious work requires direct, delegated power from God rather than mere human scholarship or devotional zeal.
The path of initiation The author outlines the specific, required steps for salvation, beginning with faith and moving through repentance and baptism. Each step is presented as a precise law of nature that, when followed, yields predictable spiritual results.
The restoration of light The text explains how the original Church of Christ fell into a state of "gross darkness" and apostasy. It highlights the pivotal role of Joseph Smith, who serves as the vessel through which the ancient Priesthood keys were returned to the earth.
The mission to the dead A significant portion of the book focuses on the "gospel preached to the dead." By linking the living with their ancestors through vicarious work, the author builds a bridge across the veil of death.
The final hierarchy The book concludes by detailing the afterlife, specifically the three degrees of glory. It paints a picture of a universe organized by capacity and choice, leading toward a final, perfected society.
The People
The book is less a character study and more an exploration of archetypes and figures of divine history. At the center stands Jesus of Nazareth, described not just as a Savior but as the High Priest who governs the plan of redemption. He is the active agent in both the mortal and spirit worlds, the head of the restored Church, and the future king of a global theocracy.
Joseph Smith is presented as the "favored man" who, through direct revelation, acts as the conduit for the restoration of the Priesthood. His role is that of a modern prophet who interacts with resurrected figures—such as John the Baptist and the apostles Peter, James, and John—to receive the authority necessary to organize the Church.
Adam and Eve are treated as the primordial couple whose fall into mortality was the necessary condition for human experience. The author views them as the prototypes for eternal marriage; they represent the goal of the righteous, who will be reunited in the resurrection with the power to "increase and multiply" forever.
Finally, the Latter-day Saint is the active participant in this drama. Whether acting as a "Savior on Mount Zion" through vicarious work or a citizen in the future theocratic kingdom, this person is defined by their willingness to submit to divine law. They are encouraged to look past "mouldy precedent" and embrace the progressive revelation that characterizes their faith.
In Its Own Voice
"The Church of Christ is progressive. That is, it advances in the knowledge of the truth."
The author explains that this faith is not static, but rather a living system that adds new light as its members are prepared to receive it.
"The living relatives of those who have departed without an opportunity of obeying the earthly requirements of the plan of salvation, if they have themselves been born of the water and of the spirit, stand in the name and place of the departed and receive the ordinances to be placed to the credit of the dead."
This passage describes the process of vicarious baptism, which serves as a central pillar of the author's argument regarding the universality of salvation.
What It's Really About
The central question beneath these pages is how a finite, mortal human can attain an infinite, eternal status. The author frames the entire universe—from the physical elements of the earth to the spiritual constitution of the soul—as being governed by immutable, "scientific" laws. If one learns these laws and submits to the correct authority, the result is guaranteed. Beneath the theological technicalities lies a profound desire for cosmic order. The book argues that neither the soul nor the family unit is destined for dissolution; instead, they are to be integrated into an expanding, eternal organization that eventually encompasses the entire race, governed by divine justice and mercy.
Why Read It Today
Readers interested in the history of ideas will find this book a remarkably clear window into the late-nineteenth-century American religious landscape. It is not a detached sociological study, but a passionate, confident manifesto written by a true believer who views his faith as a precision-tooled solution to the chaos of modern life. Those who enjoy theology written as an architecture of logic will appreciate the author’s insistence that God’s house is a "house of order."
However, modern readers should be prepared for the book’s unwavering dogmatism and its specific period attitudes. The author writes with a certainty that may feel jarring to contemporary sensibilities, particularly in his dismissive characterizations of other Christian traditions and his rigid definitions of gender roles, which are presented as essential, unchanging cosmic facts. The prose is earnest and elevated, often shifting into the declamatory style of a pulpit sermon. While the technical explanations of "Priesthood" and "celestial marriage" can be dense, the book remains a essential primary source for understanding the development of a major American religious movement. It leaves the reader with a vivid sense of a world that viewed itself as standing on the precipice of a new, divine age, where even the dead and the distant past were to be reclaimed and perfected.
