The Argument from Inconsistent Revelations

The Argument from Inconsistent Revelations says the world’s major religions make contradictory claims about God, salvation, morality, and the afterlife - so they cannot all be right, and the very pattern of disagreement makes divine revelation look unreliable. They can all be wrong, but they cannot all be right. We score it 60/100 for soundness because the core fact - religions contradict each other on basic questions - is undeniable. John Locke first developed it during the Enlightenment in 1689, David Hume sharpened it, and Sam Harris has revived it in recent decades.

The Core Argument

The logic is simple:

1. The world’s major religions each claim to have divinely revealed truth.
2. These religions make contradictory claims about God, salvation, moral commands, and the afterlife.
3. Contradictory claims cannot all be true at the same time.
4. At most one religion’s revelations can be correct - meaning billions of sincere believers who claim divine guidance are wrong.
5. This widespread pattern of religious error makes divine revelation an unreliable source of knowledge.

The argument’s power comes not from any single contradiction but from the sheer scale. There are roughly 4,000 religions in human history. Each tradition has sincere believers who report real spiritual experiences confirming their faith. If divine revelation were a reliable way to discover truth, we would expect it to converge on a single coherent picture. Instead, it produces thousands of incompatible pictures.

God’s Nature - Irreconcilable Differences

The deepest contradictions concern who or what God is.

Christianity teaches a Trinitarian God - one divine being existing as three equal persons: Father, Son, and Holy Spirit. Islam considers this view blasphemous. The doctrine of Tawhid insists God is absolutely one and cannot be divided. Hinduism presents the divine as Brahman - an impersonal, infinite reality that shows up through millions of deities. Buddhism, in its original Theravada form, holds that no creator god exists at all.

These are not minor differences. They are logically incompatible descriptions of ultimate reality. God cannot be at the same time three persons and absolutely one. God cannot be both a personal being who commands worship and an impersonal force beyond all attributes. A creator god either exists or does not. No amount of interfaith goodwill resolves these contradictions.

Salvation - Contradictory Paths

Religions disagree deeply about what happens after death and how humans reach their ultimate spiritual destiny.

Christianity holds that salvation comes through faith in Jesus Christ as Lord and Savior. Without this faith, according to traditional doctrine, the soul faces eternal separation from God. Islam teaches that salvation requires submission to Allah through the Five Pillars - including the shahada (the declaration that there is no god but Allah and Muhammad is his prophet). Hinduism offers multiple paths to moksha - liberation from the cycle of rebirth - through knowledge, devotion, or action. Buddhism teaches liberation through the Noble Eightfold Path, dissolving the illusion of a permanent self.

These paths do not complement each other. If Christianity is correct, devout Muslims and Hindus who reject Christ are lost. If Islam is correct, Christians who worship Jesus as divine commit shirk - the unforgivable sin of associating partners with God. Each tradition’s view of salvation explicitly excludes the others.

Moral Commands - Divergent Instructions

If God is sending moral truth to humanity through revelation, we would expect consistent moral teachings. Instead, religions disagree on nearly every moral question.

Islam permits polygamy (up to four wives); Christianity traditionally forbids it. Hinduism’s caste system assigns moral duties by birth; Buddhism explicitly rejects caste distinctions. Judaism imposes detailed dietary laws; Christianity (following Paul’s letters) largely drops them. Some traditions require animal sacrifice; others consider it sinful. Some permit or encourage religious warfare; others teach strict pacifism.

These are not small cultural variations. Each tradition claims its moral framework comes from divine authority. A God who at the same time commands and forbids the same practices is sending contradictory instructions - or, more likely, humans are projecting their cultural norms onto the divine.

The Geographic Problem

Maybe the most damaging fact about divine revelation is the sociology of religious belief. A person born in Saudi Arabia will almost certainly be Muslim. A person born in India will likely be Hindu. A person born in Utah will probably be Mormon. A person born in Thailand will likely be Buddhist.

If God were revealing objective truth to humanity, we would expect this truth to be accessible no matter where you were born. Instead, the single strongest predictor of religious belief is birthplace - not evidence, reason, or divine experience. This is exactly what we would predict if religions are human cultural products rather than divine revelations.

Sam Harris has argued that this geographic dependency exposes how arbitrary religious confidence is. Every believer who feels certain about their tradition must face the fact that had they been born elsewhere, they would feel equally certain about a completely different set of claims.

Theistic Responses

Only One Religion Is Right

The most common theistic response is exclusivism: one tradition has the truth, and all others are wrong. This is logically possible but carries heavy implications. It means billions of sincere, devout believers across centuries - people who prayed, sacrificed, and organized their entire lives around their faith - are completely mistaken. It also raises the question posed by the Problem of Divine Hiddenness: why would a loving God allow such widespread religious error, especially when the stakes (eternal salvation or damnation) are supposedly infinite?

Core Commonalities

Religious pluralists argue that all traditions point to the same underlying truth - they just use different languages and symbols. John Hick’s pluralistic hypothesis suggests all religions are culturally shaped responses to the same transcendent reality.

The problem is that the differences are far more specific and important than the similarities. Saying “all religions agree there is something beyond the physical” is about as informative as saying “all political ideologies agree that governance matters.” The agreements are vague; the disagreements are precise and impossible to reconcile.

Progressive Revelation

Some theologians argue God reveals truth gradually, so earlier religions contain partial truths that later revelations correct and complete. But this framework assumes that one’s own tradition is the final word - a claim each religion makes about itself. Muslims view the Quran as God’s final revelation correcting Christian errors. Mormons view the Book of Mormon as correcting mainstream Christian errors. Baha’is view Baha’u’llah’s writings as correcting Islamic errors. The chain of “corrections” does not converge; it spreads out.

The Psychological Explanation

Cognitive science offers another explanation for religious diversity. Cognitive science of religion research suggests humans are naturally wired to detect agency, find patterns, and build stories about invisible beings. Evolutionary psychologist Pascal Boyer argues that religious concepts arise from ordinary mental processes - specifically, our tendency to attribute events to intentional agents and to remember and pass on ideas that violate normal expectations in attention-grabbing ways.

This framework cleanly explains both the universality of religion (all cultures produce it because all human brains share the same biases) and its diversity (each culture shapes these tendencies differently). It predicts exactly what we observe: widespread religious belief with huge variation in specific claims.

Relationship to Other Arguments

The Argument from Inconsistent Revelations strengthens other anti-god arguments. Combined with the Burden of Proof Argument, it builds the case that religious claims lack good evidence - especially since the “evidence” believers cite (personal revelation, scripture, miracles) leads to contradictory conclusions. Combined with the Problem of Divine Hiddenness, it deepens the puzzle of why a loving God would allow such widespread religious confusion on matters of supposed eternal importance.

The argument has limits, though. It is most devastating against religions that claim exclusive divine revelation. It is less effective against deistic (a creator who does not intervene) or pantheistic (God is the universe) concepts of God that do not rely on specific revelations.

Our Scoring

The soundness score of 60 is high because the core fact is undeniable. The world’s religions do contradict each other on basic claims. The logical conclusion - that at most one can be correct, and likely none are receiving reliable divine communication - follows directly. The score is not higher because the argument does not strictly prove that no God exists; it proves only that the pattern of revelation is unreliable as evidence.

The Personal God score of 15 is extremely low. A personal, communicating God who wants a relationship with humanity should deliver a consistent message. The fact that divine revelation produces thousands of mutually exclusive belief systems is exactly what we would expect if no such God exists. The low score reflects how nearly impossible it is to square a communicating deity with the observed chaos of religious claims.

The Creator score of 35 is moderately low but much higher than the Personal God score. A creator or designer who built the universe but never tried to share specific truths with humanity would not be undermined by human religious confusion. The contradictions in revelation say nothing about whether the universe was designed - only about whether the designer is sending messages.

The Higher Power score of 40 is the highest of the three because an impersonal force or consciousness behind reality would have no reason to deliver coherent revelations in the first place. If the “higher power” is more like gravity than like a person - a basic feature of reality rather than a communicating mind - then the inconsistency of human religions is entirely irrelevant to its existence. The score stays below 50 because the argument still somewhat undermines the idea that humans have real spiritual access to transcendent reality.
