The CES Letter, written by Jeremy Runnells in 2013 as a response to his faith crisis, has become one of the most widely circulated critiques of The Church of Jesus Christ of Latter-day Saints. It raises approximately eighty distinct challenges across scripture, history, archaeology, DNA evidence, polygamy, and translation methodology. For many members who encounter it, the experience is psychologically overwhelming: a feeling of intellectual helplessness in the face of what appears to be an avalanche of unanswerable problems.
This essay does not attempt to answer every point the CES Letter raises. That approach plays directly into the document's rhetorical design and loses by design. Instead, this essay examines the letter's logical architecture, the strategy underlying its construction, and demonstrates that the document's primary power lies not in the strength of its individual arguments but in a series of well-documented rhetorical techniques that exploit cognitive limitations rather than engage honest inquiry.
Understanding those techniques does not resolve every historical question the letter raises. It does something more important: it restores the reader's ability to evaluate the letter on its actual merits rather than its manufactured momentum.
The Gish Gallop: Volume as a Substitute for Substance
The foundational rhetorical strategy of the CES Letter is what logicians and debate scholars call the Gish Gallop, named after creationist debater Duane Gish, who perfected the technique of overwhelming opponents with sheer volume of claims rather than depth of argument.
The strategy exploits a fundamental asymmetry: a claim can be stated in a sentence; refuting it properly may require paragraphs. Fire enough claims rapidly enough and the opponent faces an impossible choice: attempt to address everything and appear to be losing ground with every unanswered point, or address a few carefully and appear to be ignoring the rest. Either way the arguer wins not by being right but by being numerous.
The CES Letter's eighty-plus challenges are not structured as a single coherent argument. They are structured as a barrage. A reader who has solid, well-researched responses to seventy-five of them will still feel the remaining five as an unscalable wall. The psychological experience is of being overwhelmed even when the intellectual reality is that most points have been addressed, often thoroughly, by LDS scholars, apologists, and the Church's own Gospel Topics Essays.
The correct response to a Gish Gallop is not to answer every point. It is to name the strategy, establish what the foundational question actually is, and decline to accept the premise that volume equals validity. The CES Letter's quantity of challenges is not evidence of the Church's falsity. It is evidence that a motivated critic can generate a very long list.
Front-Loading Emotional Shock: Softening the Critical Faculties
The CES Letter does not open with its most historically complex or philosophically rigorous challenges. It opens with its most emotionally disturbing ones: polygamy, polyandry, Joseph Smith's marriages to teenagers, treasure seeking, and financial controversies. This sequencing is not accidental.
Emotional shock degrades critical thinking. A reader who has absorbed a sustained barrage of morally distressing material is significantly less equipped to evaluate the archaeological and textual claims that follow. By the time the letter addresses Mesoamerican archaeology or Book of Mormon anachronisms, the reader's defenses have already been softened by the emotional weight of the earlier sections.
This technique is well understood in rhetoric and persuasion: establish an emotional frame first, then introduce the analytical content. The emotional frame colors everything that follows. A reader who is already disturbed and unsettled is far less likely to pause and ask: "Is this claim actually established? What is the quality of the evidence here? Has the Church addressed this?"
Recognizing this sequencing does not make the historical questions disappear. It does restore the reader's ability to evaluate them with appropriate intellectual distance rather than from within an emotional state the letter deliberately induced.
Category Conflation: Treating All Problems as Equally Damning
One of the letter's most significant logical failures is its treatment of fundamentally different categories of challenge as though they carry equivalent weight. The CES Letter presents the following as though they belong in the same category of evidence:
- Demonstrable factual errors
- Legitimate historical uncertainties
- Unanswered scholarly questions
- Contested interpretations of archaeological evidence
- Points that have been directly addressed by the Church or LDS scholars
- Points where current scholarly consensus has shifted since the letter was written
These are not the same thing. A demonstrable factual error in a foundational truth claim is genuinely significant. An unanswered question about pre-Columbian metallurgy is categorically different: it is an absence of current evidence, not evidence of absence, and archaeological understanding continues to develop. An interpretation disputed among scholars is different again.
By presenting all of these under the same rhetorical umbrella, the letter creates a false impression of uniform devastation. In reality, the challenges vary enormously in their nature, their severity, and the degree to which they have or have not been adequately addressed. A careful reader who sorts the letter's challenges by category would find the picture considerably less uniform than the document implies.
The Burden of Proof Problem: Uncertainty Is Not Disproof
Running throughout the CES Letter is an implicit and undefended epistemological standard: any unanswered question constitutes disproof of the whole. If an archaeological question about the Book of Mormon cannot be definitively resolved in the Church's favor, the letter treats this as evidence against the Church's truth claims.
This standard does not hold for any complex historical or religious claim. We do not discard George Washington's historical existence because some details of his biography are disputed or uncertain. We do not reject the foundations of established history because archaeological evidence is incomplete or because scholarly interpretations conflict. Uncertainty is the normal condition of historical inquiry, not a disqualifying one.
The burden of proof works in both directions. The CES Letter bears the burden of establishing not merely that questions exist but that those questions cannot be resolved within a framework that grants the possibility of genuine revelation. It does not meet that burden. It assumes it has been met simply by virtue of raising the questions.
This is a logical fallacy known as argumentum ad ignorantiam: arguing from ignorance, or treating the absence of a complete answer as proof of a negative conclusion. The absence of current archaeological evidence for horses in pre-Columbian America does not prove the Book of Mormon is false; it proves that current evidence does not confirm that specific detail. Those are very different claims.
The Framework Problem: Immanent Critique Requires Honest Premises
Perhaps the most fundamental logical failure of the CES Letter is one that runs beneath every individual argument: the letter evaluates LDS claims using a naturalistic framework that excludes revelation as a legitimate category of evidence, without ever acknowledging or defending that exclusion.
This matters enormously. A believer who grants that Joseph Smith received genuine revelation from God has an entirely different framework for evaluating translation methodology, historical gaps, and doctrinal development than a skeptic who has already ruled out that possibility. The letter never engages the believer's framework honestly. It simply assumes the naturalistic framework is correct and proceeds as though that assumption requires no defense.
This is circular reasoning - specifically the fallacy of begging the question. The letter's implicit argument runs:
- Joseph Smith's claims cannot be supernaturally explained
- Therefore the historical anomalies must have naturalistic explanations
- Therefore Joseph Smith fabricated the revelations
But the first premise - that supernatural explanation is unavailable - is precisely what the letter should be establishing. Instead it is assumed from the outset. The entire analytical structure rests on a foundational premise that is never argued for and that the letter's intended audience, believing Latter-day Saints, explicitly rejects.
A philosophically honest critique of LDS truth claims would need to engage the question of whether Joseph Smith could have been a genuine prophet before proceeding to evaluate the evidence under that hypothesis. The CES Letter skips that foundational question entirely and builds its entire structure on the assumption that the answer is already no.
Special Pleading: An Unequal Standard of Evidence
The CES Letter applies to LDS claims a standard of historical and archaeological certainty that it never applies to its own implicit counter-claims, and that it would not apply consistently to any other ancient religious tradition.
Consider: if the standard is no archaeological gaps, no historical uncertainties, no anachronistic details, no doctrinal development over time, and no disputed translations, then no ancient religious tradition survives. The historical foundations of Christianity, Judaism, Islam, and virtually every other major world religion contain precisely these features. The letter applies its forensic standard selectively to LDS claims while implicitly exempting the naturalistic worldview it is defending from the same scrutiny.
This is the fallacy of special pleading: applying a stricter evidential standard to one case than you would apply to genuinely comparable cases. A fair and consistent application of the letter's own standard would require the same skepticism toward the historical reliability of the New Testament, the archaeological basis of Exodus, and the translation history of every ancient religious text. The letter shows no interest in that consistency.
The Appropriate Response: Address the Architecture, Not the Volume
For a Latter-day Saint who encounters the CES Letter, the temptation is to attempt to answer every point, to prove that each individual challenge can be met. This is understandable but strategically mistaken. It accepts the letter's terms and plays into its design. The Gish Gallop wins precisely when the opponent agrees to fight on those terms.
The more effective and intellectually honest response addresses the letter's architecture rather than its volume:
Name the strategy. The letter is structured as a Gish Gallop. Recognizing that does not answer any individual question, but it correctly identifies why the experience of reading it feels overwhelming regardless of the quality of the individual claims.
Establish the foundational question first. Did Joseph Smith receive genuine revelation or not? Everything else flows from that single premise. The letter never honestly engages this question. It assumes the answer and builds on that assumption.
Apply the burden of proof correctly. Uncertainty is not disproof. Unanswered questions are the normal condition of historical inquiry. The letter must establish not merely that questions exist but that they are unresolvable within a framework that permits revelation.
Sort the challenges by category. Genuine errors, scholarly uncertainties, contested interpretations, and already-addressed questions are not epistemically equivalent. Treat them accordingly.
Note the selective standard. The evidential standard the letter applies to LDS claims would destroy virtually every ancient religious tradition if applied consistently. Pointing this out is not a deflection. It is a legitimate logical observation about the letter's intellectual honesty.
Engage the framework question. The letter's entire analytical structure assumes naturalism without defending it. A believer is under no obligation to accept that assumption before the argument has even begun.
Conclusion
The CES Letter is a rhetorically sophisticated document. Its power comes not primarily from the strength of its individual arguments - many of which have been addressed, some at length, by LDS scholars and the Church itself - but from its volume, its emotional sequencing, its category conflation, and its undefended foundational assumptions.
None of this means that every question the letter raises is trivial or that honest inquiry into LDS history is inappropriate. The Church itself has encouraged members to engage difficult historical questions through its Gospel Topics Essays and other resources. Honest inquiry and robust faith are not enemies.
What the letter discourages - and what this analysis aims to restore - is the reader's ability to evaluate claims on their actual merits rather than their manufactured momentum. A question deserves an honest answer. A Gish Gallop deserves to be named.
