The Spirit of God as Fire

In Short

This 1870 theological treatise blends mid-19th-century astronomical observation with a literal interpretation of scripture to propose a striking cosmological hypothesis: Heaven is a physical, interior world located within the sun. The author argues that the sun’s "photosphere" acts as a shield, protecting an inner, temperate globe where the spirits of the saved reside in eternal light. By reconciling scientific discovery with biblical prophecy, the work seeks to provide a rational, modern foundation for faith, urging readers to prepare for their inevitable transition to this celestial home.

The Story

The narrative begins by establishing the necessity of a future state for the human soul, rooted in both ancient promise and the "wondrous works of God." The author posits that astronomy, far from being a collection of guesses, is a precise science that reveals the majesty of the heavens. By examining the mechanics of the solar system—the power of gravity, the velocity of the planets, and the immense dimensions of the sun—the argument transitions from the physical to the spiritual. The sun is identified not merely as a source of light, but as a "loadstone" of divine purpose.

The arc of the book follows a trajectory from the earthly to the infinite. After surveying the physical properties of the solar system, the author turns his attention to the "Spirit of God as fire." He argues that fire, in its ethereal form, is the element through which God manifests His presence. Because the sun is the ultimate source of this fire, it serves as the logical locus for the divine throne. The text then addresses the "dimensions and capacity" of this heavenly world, meticulously calculating the vast number of mansions required to house the souls of all who have ever lived, concluding that the sun’s interior is sufficiently vast to accommodate them all.

The narrative darkens when it addresses the destiny of the wicked. The author asserts that a "great gulph" exists between the righteous and the damned, mirroring the physical void that astronomers observe between the sun’s outer, incandescent photosphere and its inner, habitable core. The final sections shift from cosmological speculation to a pastoral appeal. The author critiques the divisions within the contemporary Protestant church, arguing that such "blind leaders" have obscured the plain plan of salvation. He calls upon ministers and laypeople alike to look past sectarian conflict and recognize the "glory-light" of the Spirit. The story concludes with an urgent, personal invitation: death is certain, the judgment is absolute, and the way to the sun—the Paradise of God—is open to any who will choose to follow the light.

How It Unfolds

The foundation of belief The author sets the stage by affirming the immortality of the soul and the reliability of scripture, asserting that faith and science are not contradictory. He establishes that the "great Architect" has left clues to His nature in the precise order of the heavens.

The astronomical bridge He introduces the reader to the grandeur of the solar system, utilizing measurements of light and speed to make the vastness of space comprehensible. This segment treats astronomers as essential guides, like mariners consulting a chart, to demonstrate the consistency of natural law.

The solar hypothesis Here, the argument reaches its core, proposing that the sun is composed of an outer shell of fire and an interior void, which protects a massive, habitable globe. He supports this by connecting the biblical description of heaven’s light to the physical reality of the sun’s radiance.

The moral geography The text differentiates between the destination of the saved and the condemned. By placing heaven within the sun and hell in the dark, intermediate voids, he provides a literal map for the afterlife.

The final appeal The book concludes by addressing the reader directly, moving from the cosmic scale back to the individual soul. He challenges the reader to set aside worldly distractions and theological uncertainty to secure a place in the celestial city.

The People

The book focuses on the "Great Architect," the central divine figure who acts as the primary force behind both the laws of physics and the plan of human salvation. He is the provider of light and the judge of all souls. The author, D. Mortimore, positions himself as a mediator between the "intelligence of the world" and the mysteries of the firmament. He is a man of science and faith who seeks to liberate the reader from "superstition" and the "intolerance" of the Roman Catholic Church, which he views as a major obstacle to the truth. The "righteous" are the seekers who, through the "One Mediator," strive to reach their eternal home. They are characterized by their weariness with the "tempest of life" and their desire for the rest promised in the City of God. Finally, the "wicked" serve as the cautionary figures, those who have failed to heed the "gentle drawings of the spirit" and face an eternity of darkness, separated from the divine flame.

In Its Own Voice

Regarding the divine nature of the celestial realm, the author writes:

"Now we see that this declaration establishes our hypothesis of the location of heaven. His going forth from the end of the heaven--from the sun--and nothing is hid from the heat thereof--the Sun being the source of heat--is conclusive evidence that the Sun is near--even at the ends of the heaven."

Regarding the reliability of the astronomical science he employs, he notes:

"Let such sceptics think of the certainty with which sidereal events are predicted beforehand. Let them reflect on the evidence of the most exact knowledge of the heavenly bodies involved in the calculation of eclipses, in fixing the very moment when the moon's dark outline shall begin to creep over the sun's bright disk."

What It's Really About

The central argument is a reconciliation of the material and the spiritual. The author seeks to prove that heaven is not a vague, ethereal "somewhere," but a concrete, physical reality located within the sun. This serves as an attempt to save religion from the encroaching skepticism of the 19th century by grounding spiritual truths in observable natural phenomena. The book asks: If the laws of gravity and light are so clearly ordered by a Creator, why should the destination of the soul not follow a similarly logical, physical design? Ultimately, it is a work of cosmic optimism, asserting that the universe is not a chaotic void, but a purposefully organized mansion designed to house the entirety of human existence.

Why Read It Today

Readers interested in the history of science and theology will find this book a fascinating look at the mid-Victorian impulse to synthesize disparate worldviews. It provides a window into a period where the telescope was seen as a tool for mapping the afterlife as much as the stars. The prose is earnest, often oratorical, and carries the weight of a man who believes he has decoded the architecture of eternity.

The book is not without challenges. Its anti-Catholic sentiment is intense and pervasive, reflecting the specific sectarian anxieties of its time. Additionally, the author’s tendency to mix complex astronomical measurements with emotional biblical appeals can feel jarring to a modern reader. However, for those curious about the "literary intelligence" of 1870, the book offers a sincere, if eccentric, vision of a universe ablaze with divine intent. It is a testament to the human desire to bring the vast, cold distances of space into a familiar, domestic scale. What stays with you is the author's relentless conviction that we are not drifting in a meaningless dark, but are instead being drawn toward a literal, burning center of light—a "home" that is both a scientific object and a spiritual sanctuary.
