The $100 Bet
“I will bet any Christian $100 that I can prove that biblical Christianity can not be true by the laws of reason..”
“I will bet any Christian $100 that I can prove that biblical Christianity can not be true by the laws of reason..”
Logic is not a Christian invention, nor even a Western one exclusively — it predates Christianity by centuries and belongs to no single tradition or faith. Formal logic was systematized by Aristotle in the 4th century BCE, in works like the Prior Analytics, where he laid out the syllogism and the basic laws that still govern valid reasoning today: the law of non-contradiction (a statement and its opposite cannot both be true at the same time, in the same sense) and the law of the excluded middle (a statement is either true or false, with no third option).
Independently, ancient Indian philosophical schools developed their own sophisticated systems of logic and epistemology (such as Nyaya) around the same era, and Chinese philosophers of the Mohist school were formalizing rules of valid inference during a similar period. None of this required Christianity, the Bible, or any religious framework to exist — logic developed as a secular tool for testing whether conclusions actually follow from premises, and whether claims about the world hold up against evidence. That's precisely why it functions as a neutral standard: it doesn't belong to atheists, and it doesn't belong to Christians. It's a shared set of rules for discerning what's actually true, and any claim — religious or otherwise — has to be willing to be tested against it.
Biblical Christianity makes claims that are false, therefore, biblical Christianity is false.
Why Biblical Literalism Doesn’t Hold Up to Reason
I recently made a bet for $100 to any Christian that I could prove that biblical inerrancy — the claim that the Bible is 100% factually and scientifically accurate — survives contact with what we actually know about the world. Here’s the case.
Truth Isn’t Relative - Understanding Logic
My claim was “biblical Christianity can not be true by the laws of reason”
it can’t.
Before getting into specifics, one ground rule. Truth is not a matter of personal perspective. A claim is either true or it is not — that applies the same way to a skeptic as it does to a believer. This is just the baseline any factual claim has to meet if it wants to be evaluated as true rather than as poetry, metaphor, or personal meaning.
That distinction matters, because the Bible gets read both ways. Some traditions treat it as inerrant history and science. Others read Genesis and similar passages as theological narrative, neither stands the test of logic.
The Claims That Don’t Hold Up
If the Bible is read as a literal, scientific, historical document, here are some of the claims that conflict with what we know from physics, biology, geology, and linguistics:
Cosmology
A solid “firmament” separating waters above the sky from waters below (Genesis 1) — there is no such structure.
The sun and moon are created after light and day/night already exist (Genesis 1).
The sun stopping in the sky (Joshua 10) — this would require either a geocentric universe or the Earth halting its rotation without annihilating everything on its surface.
Earth’s surface at the equator is moving at about 1,670 km/h (1,040 mph) due to rotation. Everything on the surface — people, oceans, the atmosphere, buildings, you — is moving at that same speed along with the ground. That’s why we don’t feel it: relative to everything around us, we’re stationary.
If Earth stopped rotating suddenly (over seconds or minutes), here’s what would follow from basic physics:
Everything not bolted to bedrock keeps moving. By Newton’s first law, objects in motion stay in motion unless acted on by a force. If the ground under you stops but you don’t, you’d be launched eastward at over 1,000 mph — same for oceans, the atmosphere, loose soil, buildings, trees, all of it.
The atmosphere becomes a planet-scale wind event. Air isn’t rigidly attached to the ground. A sudden stop would essentially turn the entire atmosphere into a continuous hypersonic wind, scouring the surface.
The oceans would not stay put. All that water, still moving at rotational speed, would surge as continent-scale tsunamis in the direction of Earth’s former spin.
Structures and geology. Anything not deeply anchored — cities, forests, topsoil — would be stripped away by the combined effect of inertia and wind shear.
Slower stop, different problem. If instead Earth’s rotation slowed gradually over days or longer (avoiding the inertia catastrophe above), you’d get a different set of issues: day/night cycles would stretch dramatically, temperature extremes between the sunlit and dark sides would become severe, and eventually — if it fully stopped — one side would face permanent day and the other permanent night, similar to how the Moon is tidally locked to Earth.
“Four corners of the earth” (Isaiah 11, Revelation 7) — language implying a flat, cornered earth. The earth is observably round.
Biology and genetics
Lifespans of 600–900+ years (Genesis 5, e.g., Methuselah at 969) — no human biology supports this- it’s impossible.
Two of every land animal surviving together on one vessel, including species with mutually exclusive climate and dietary needs (Genesis 6–7).
All of humanity’s genetic diversity descending from two people, or from eight after the flood — population genetics shows the human line was never smaller than several thousand individuals.
Geology
A global flood covering the highest mountains — the required water volume doesn’t exist, and there’s no corresponding disruption in ice cores or sediment layers, which instead show continuous, undisturbed deposition.
Linguistics
All human languages emerging suddenly at Babel (Genesis 11) — contradicts everything we know about languages diverging gradually over tens of thousands of years.
Taken together, these examples describe a pattern: where the Bible makes falsifiable claims about the physical world, those claims consistently conflict with independent, converging lines of evidence from multiple scientific fields.
The Real Question for Believers
If your position is that Genesis 1–11 is theological narrative rather than a science textbook, this argument was never aimed at you — and it’s worth saying so plainly, because conflating the two audiences is where a lot of these debates go nowhere.
But if your position is that the Bible is inerrant in literal, scientific detail, the burden is on that position to explain why its claims about the physical world consistently diverge from the physical world itself. “I have faith” is a not a scientific rebuttal. Claiming God works in mysterious ways doesn’t satisfy logic, and thus my original claim, ““I will bet any Christian $100 that I can prove that biblical Christianity can not be true by the laws of reason..” is proven correct.
Philosophical Problems the Bible Struggles to Answer
Beyond empirical claims about the physical world, biblical Christianity faces several long-standing philosophical challenges that have never been fully resolved to universal satisfaction — even among theologians.
The Problem of Evil. If God is omnipotent (all-powerful), omniscient (all-knowing), and omnibenevolent (perfectly good), why does evil and suffering exist? God would have the power to prevent it, the knowledge to foresee it, and — if perfectly good — the will to stop it. Yet natural disasters kill children, diseases ravage the innocent, and horrific suffering occurs with no discernible connection to moral desert. Philosophers have formalized this as a logical trilemma: it seems you can hold at most two of “God is all-powerful,” “God is all-good,” and “evil exists” without contradiction. The standard theological responses — free will defenses (evil results from human free choice, which is itself a good God permits), soul-building theodicies (suffering develops moral character), or appeals to mystery (God’s reasons are beyond human comprehension) — are taken seriously in philosophy of religion, but none has achieved consensus even among believers, and each carries its own weaknesses (free will doesn’t explain natural disasters or animal suffering, for instance).
The Euthyphro Dilemma. Originally posed by Plato: is something good because God commands it, or does God command it because it is good? If the former, morality becomes arbitrary — anything God commands, including atrocities, would be “good” by definition. If the latter, then goodness exists independently of God, and God is simply reporting on a moral standard he didn’t create — which undermines the idea that God is the ultimate source of morality.
Divine Hiddenness. If God wants a relationship with humanity and desires belief, why does he remain hidden rather than providing unambiguous evidence? Many people who would sincerely believe given clear evidence do not encounter any — which seems in tension with a God who both wants belief and has the power to provide sufficient grounds for it.
The Problem of Hell and Divine Justice. Eternal, infinite punishment for finite, temporal sins raises a proportionality problem: how is infinite punishment a just response to finite wrongdoing, especially for people who never had meaningful access to the Gospel due to geography or historical era?
Omniscience and Free Will. If God knows the future with certainty — including every choice you will ever make — in what sense are those choices genuinely free? This tension between divine foreknowledge and human free will has generated centuries of unresolved debate (Calvinist predestination vs. Arminian free will being one major fault line within Christianity itself).
So, here are some claims that make the initial claim, “biblical Christianity can not be true by the laws of reason..“, verifiable:
P: A moral standard applied inconsistently, using categories invented after the fact rather than stated in the text, is not a moral standard at all — it’s arbitrary preference dressed as principle. More precisely: if a source claims to be the fixed, eternal standard of morality, but its adherents require an external, unstated framework to decide which of its commands still bind, then the source is not functioning as the standard — the external framework is.
Christians frequently invoke Leviticus 19:26-31 and Deuteronomy 18:10-12 to condemn astrology and divination as forbidden practices, treating these prohibitions as timeless moral law. Yet Leviticus 11:9-12 forbids eating shellfish, Leviticus 19:27 forbids trimming the edges of one’s beard, and Leviticus 19:19 forbids wearing garments woven of two different fibers — commands appearing in the same books, often the same chapters, with no textual marker distinguishing permanent from expired prohibitions. The standard response is that shellfish and mixed fibers belong to the Old Covenant while the divination ban survives into the New — but this division into “moral,” “ceremonial,” and “civil” law appears nowhere in Leviticus itself; it was formalized centuries later by theologians precisely to resolve this inconsistency, meaning the sorting criterion is applied after the fact rather than derived from the text. The problem compounds once the standard is applied consistently: the Ten Commandments themselves include the Sabbath command (Exodus 20:8-11), with Exodus 31:14 specifying death as the penalty for violation, yet almost no modern Christian keeps a Saturday Sabbath under threat of execution — meaning even commands inside the supposedly “permanent” category are quietly set aside when inconvenient.
P: If a moral code is only followed when convenient and abandoned when it isn’t, adherence to that code is not evidence of the code’s authority — it’s evidence that something other than the code is doing the moral reasoning.
Genesis 19 depicts Lot offering his daughters to a mob to be raped in his guests’ place, and later his daughters getting him drunk to conceive children by him — episodes the text narrates without explicit condemnation, yet Lot is called “righteous” in 2 Peter 2:7-8, and no modern Christian treats either act as a model. Slavery is regulated, not merely tolerated: Exodus 21:20-21 permits beating a slave provided the slave survives a day or two afterward, and Ephesians 6:5 instructs slaves to obey their masters — passages 18th- and 19th-century defenders of American chattel slavery cited directly. Usury is explicitly forbidden (Exodus 22:25, Deuteronomy 23:19), yet mortgages and interest-bearing accounts are standard practice among Christians. And 1 Timothy 2:12 and 1 Corinthians 14:34-35 restrict women from teaching or speaking in church — commands actively contradicted by female pastors across most Protestant denominations today. The pattern is consistent: commands are sorted into “binding” and “expired” not by any principle stated in the text, but by whether the command is compatible with contemporary moral and economic life.
P: A text authored or inspired by an omniscient being cannot contain claims that are factually false about the world that being created — so factual error in scripture is logically incompatible with the claim of divine omniscient authorship.
Genesis 1:6-8 describes a solid firmament — Hebrew raqia, denoting something hammered out and solid — separating waters above the sky from waters below; no such structure exists, and an omniscient author would know this. The standard defense, “divine accommodation” (that scripture speaks in the cosmological language of its original audience), concedes the actual point: it admits the text describes a false cosmology and merely relocates the explanation from “true” to “pastorally convenient,” abandoning inerrancy in the process. Population genetics adds an independent line of evidence: geneticists estimate historical population sizes using coalescent theory, and this method consistently shows the human lineage never dropped below several thousand breeding individuals at any point. The clearest evidence is the MHC/HLA immune-gene complex, the most variable genes in the human genome — some variants predate the human-chimp divergence roughly six million years ago. Two founding individuals could pass on at most four versions of any single gene; the number of ancient, divergent immune-gene lineages in living humans far exceeds four, which is only possible if the ancestral population was always in the thousands, not two.
P: If moral culpability requires a capacity for abstract reasoning that emerged gradually over evolutionary time, and salvation requires knowledge that existed only in the last 2% of human history, then a doctrine of universal judgment applied to all humans who ever lived contains a category error — it presumes a uniform moral agent and a uniform access to salvation that never existed.
Anatomically modern humans have existed for roughly 300,000 years; Christianity for roughly 2,000 — meaning knowledge of Christ was unavailable for at least 98% of the time our species has existed, encompassing the overwhelming majority of every human who ever lived. No consensus answer exists for what happens to these souls: Catholic tradition proposes a retroactive “Harrowing of Hell,” Paul argues in Romans 2 that conscience alone may suffice, and other traditions leave the question unresolved — the existence of multiple competing patches suggests the doctrine wasn’t built with this timeline in mind. The problem sharpens with cognitive evolution: the prefrontal cortex, most associated with abstract moral reasoning, developed gradually across hundreds of thousands of years, meaning the capacity for theological culpability Christian doctrine presumes is itself a cognitive achievement, not a fixed constant present in every hominin that ever lived.
P: If the central narrative elements and honorific titles of a claimed unique revelation were already common currency in the surrounding culture at the time it appeared, then the narrative’s claim to originality — not its truth, but its claim to be unprecedented — cannot be assumed and must be argued for rather than taken as given.
Osiris, whose cult predates Christianity by over two thousand years, was killed, dismembered, and resurrected as ruler of the dead. Dionysus, in Orphic tradition, was torn apart as a child and reborn, enacted in mystery-cult initiation for centuries before the first century. Romulus was said to have vanished and ascended to become a god — a claim Livy records contemporaries doubted at the time, suspecting a cover story for an ordinary murder. The titles applied to Jesus — “son of god,” “savior” — were already the official honorifics of the reigning Roman emperor, stamped on coins throughout the empire. None of this proves direct borrowing of any single narrative; it demonstrates that death-and-rebirth mythology and divine-sonship language were the standard cultural vocabulary of the era, and the Jesus narrative was composed in that vocabulary rather than descending as unprecedented.
P: If a text’s own composition history shows it was assembled from multiple, sometimes contradictory sources rather than delivered as a single coherent revelation, and if a claimed all-knowing designer’s biological work shows the same inefficiencies gradual, undirected evolution would predict, then both the textual and biological evidence point away from single, intentional, omniscient authorship — and toward accumulated, undirected process instead.
Mainstream biblical scholarship — the documentary hypothesis, developed by Julius Wellhausen and refined since — holds that the Torah was compiled from at least four distinct source traditions, conventionally labeled J, E, P, and D, written by different authors across different centuries and later stitched together by editors. This isn’t a fringe theory; it’s the standard framework taught in secular biblical studies departments, and it’s supported by internal evidence the text itself displays: Genesis contains two different creation sequences with conflicting details (compare Genesis 1’s order of creation to Genesis 2’s), and two flood narratives interwoven with inconsistent details about how many animals Noah brought aboard. A text assembled this way is difficult to reconcile with the claim of single, coherent divine authorship — the seams are visible in the text itself, independent of any external scientific claim. The same pattern shows up in biology: an omniscient designer’s work should not be expected to contain the specific inefficiencies that undirected evolutionary history, and only that history, predicts. The human eye is wired backward, with the retina’s blood vessels and nerve fibers running in front of the light-sensing cells, creating a blind spot at the optic nerve — the sort of flaw a designer starting from scratch would have no reason to include, but exactly what evolution predicts from an eye built by modifying earlier structures. The recurrent laryngeal nerve in giraffes takes a massively inefficient detour, running from the brain down the neck, looping around the aorta near the heart, and back up to the larynx — a path that made sense in a fish-like ancestor with a short neck and no such loop was ever removed as the neck lengthened over evolutionary time. Both lines of evidence — the seams in the text and the seams in the body — point to the same conclusion: accumulation and revision by imperfect, undirected processes, not the single, intentional handiwork of an all-knowing author.
P: If a text asserts two mutually exclusive sequences for the same set of events, both cannot be literally true simultaneously — this is a formal contradiction (A and not-A), not merely a factual error against outside evidence.
Genesis 1:24-27 places the creation of land animals before humans, with man and woman created together, last, after every other living thing. Genesis 2:7, 2:18-19 reverses this: man is formed first, then “the LORD God formed every animal of the field and every bird of the air” specifically to see if any would suit as a companion for him, with woman formed last, from his rib, after the animals have already been found insufficient. Genesis 2:5 additionally states “no plant of the field had yet sprung up” at the time man was formed, meaning man precedes plant life in chapter 2, directly reversing chapter 1’s plants-before-humans order. If both chapters describe the same literal sequence of events, they cannot both be accurate — one asserts humans-last, the other asserts humans-first, relative to plants and animals.
P: If two passages describe a single historical event using details that are not merely incomplete but mutually exclusive, the passages contradict rather than merely diverge — this is distinct from an empirical claim being falsified by outside data, because the contradiction exists between two internal sources.
Matthew 27:5 states Judas “went and hanged himself.” Acts 1:18 states Judas “falling headlong, burst open in the middle, and all his bowels gushed out,” with no mention of hanging, and describes the purchase of a field with the betrayal money as something Judas himself did — a detail Matthew 27:6-8 directly contradicts by saying the chief priests bought the field, since Jewish law forbade returning blood money to the temple treasury. The traditional harmonization (hanged, then the rope or branch broke, causing the fall) is not stated in either text — it is a later inference constructed specifically to resolve the tension, which is itself evidence that the two accounts, read on their own terms, do not agree.
P: If a text presents two family lineages for the same individual, tracing descent through the same intermediate ancestor (David) to the same endpoint (Joseph), and the named fathers and grandfathers differ, the two lineages cannot both be a literal, complete biological genealogy of the same person.
Matthew 1:6-16 traces Jesus’s lineage through Solomon, naming Joseph’s father as Jacob. Luke 3:23-31 traces Jesus’s lineage through Nathan, naming Joseph’s father as Heli. The two lists diverge for roughly forty generations between David and Joseph, sharing almost no names in common apart from David and Joseph himself. Traditional harmonizations (one genealogy is Mary’s, routed through Joseph as her husband; or one reflects levirate marriage) are constructions not stated in either text, introduced to reconcile lists that, read plainly, name different men as Joseph’s father and different lines of descent from David.
P: If four accounts of the same single event disagree on who was present, in what order, and what instructions were given, at least three of the four must be incomplete or inaccurate relative to whichever one (if any) is correct — they cannot all be simultaneously exhaustive and accurate reports of one historical morning.
Matthew 28:1 names two women at the tomb; Mark 16:1 names three; Luke 24:10 names at least five; John 20:1 names one (Mary Magdalene alone). Mark 16:5 describes a young man inside the tomb; Matthew 28:2-5 describes an angel who is present for the stone being rolled away, an event none of the other gospels place at that moment; Luke 24:4 describes two men; John describes two angels appearing later, on a second visit, after Mary has already left and returned. The instruction given to the women likewise differs: Matthew and Mark have them told to tell the disciples to go to Galilee; Luke has no Galilee instruction and has the women immediately believed by no one; John has no group of women at all, only Mary Magdalene, who is initially instructed not to touch Jesus, a detail absent from the other three. Read as four independent, complete, and equally literal reports of a single morning, these details cannot be reconciled into one consistent sequence of who arrived when, saw what, and was told what.
P: If a text ties a narrated event to a specific historical ruler or administrative event, and independent historical record places that ruler or event at a different time than a parallel account in the same text, at least one of the two internal claims is false — this is a contradiction generated by the text’s own specificity, not an outside empirical objection.
Matthew 2:1 places Jesus’s birth “in the days of Herod the king” — Herod the Great, whose death is independently dated to 4 BCE. Luke 2:1-2 ties the same birth to “the first census... when Quirinius was governor of Syria,” and Quirinius’s governorship, and the associated census, are independently dated to 6 CE — roughly a decade after Herod’s death. The two gospels each anchor the same single event to a specific ruler/administrative marker, and those two markers cannot occupy the same historical moment. Similarly, the synoptic gospels (Matthew 21, Mark 11, Luke 19) place the temple cleansing near the end of Jesus’s ministry, functioning as the immediate provocation for his arrest, while John 2:13-16 places what appears to be the same event near the beginning of the ministry, years earlier by John’s own chronology. Either the gospels are describing two separate incidents that no single gospel acknowledges as two, or they disagree on which point in a single ministry the event occurred — both outcomes mean at least one specific chronological claim, made by the text itself, is inaccurate.
P: A pattern of small numerical or factual discrepancies recurring across independent narrations of the same event, rather than one isolated instance, indicates a general property of the text’s composition — inconsistent transmission or authorship — rather than a single anomaly explainable by scribal accident or harmonization in one case alone.
Matthew 27:32, Mark 15:21, and Luke 23:26 state Simon of Cyrene carried Jesus’s cross; John 19:17 states Jesus carried it himself, with no mention of Simon. 2 Samuel 24:9 gives one set of troop numbers for David’s census; 1 Chronicles 21:5 gives different numbers for the same census, with 2 Samuel 24:1 additionally attributing the incitement to census-taking to God while 1 Chronicles 21:1 attributes it to Satan. Comparable numerical divergences recur elsewhere between Samuel/Kings and Chronicles narrations of the same events. Taken individually, each discrepancy might be dismissed as a copying error or a minor narrative variant; taken as a recurring pattern across independent books describing identical events, they indicate that internal numerical and factual consistency was not a controlling standard in the text’s composition or transmission.
P: If the textual basis for a claimed core doctrine, or for a widely quoted passage, is demonstrated by manuscript evidence to be a later addition absent from the earliest recoverable sources, then the doctrine’s claim to be part of the original revelation — as opposed to a later theological or scribal development — cannot be assumed and must be independently argued.
The longer ending of Mark (16:9-20), which contains the gospel’s primary post-resurrection appearance narrative and the handling-snakes/drinking-poison passage, is absent from the earliest and most reliable Greek manuscripts (Codex Sinaiticus and Codex Vaticanus) and is regarded by the modern textual-critical consensus as a later addition, not part of Mark’s original text. The story of the woman caught in adultery (John 7:53-8:11), including the widely quoted “let he who is without sin cast the first stone,” is likewise absent from the earliest manuscripts and is treated by textual critics as a later interpolation, not original to John. The Comma Johanneum (1 John 5:7-8), historically the clearest explicit Trinitarian proof-text in the King James Version (”there are three that bear record in heaven, the Father, the Word, and the Holy Ghost”), is absent from every known Greek manuscript prior to the fourteenth century and is understood to be a later scribal insertion into the Latin tradition, not part of the earliest recoverable Greek text. In each case, material that shaped doctrine or was quoted as scripture for centuries is now known, on textual-critical grounds independent of any theological argument, not to have been part of the earliest form of the text.
P: If a doctrine’s central technical terms (”person,” “being”) are defined by ordinary usage everywhere else in language, and the doctrine can only avoid contradiction by silently redefining those terms in a way found nowhere else, then the doctrine has not resolved the contradiction — it has relabeled it as a mystery at precisely the point where it fails.
Trinitarian doctrine holds that the Father, Son, and Holy Spirit are three distinct persons, each fully God, yet there is only one God, not three. In every other context, “three distinct persons, each fully possessing the complete nature of X” entails three instances of X (three men, each fully human, are three humans, not one). If “person” here doesn’t carry that entailment, the word has been redefined for this doctrine alone, and no non-circular definition of “person” has been produced that both preserves real distinction between Father, Son, and Spirit (needed so the Son can pray to the Father, or the Father can be un-incarnate while the Son is) and avoids three separate centers of consciousness, will, and being — which would be three gods. Historical formulations (Nicene homoousios, later social and modalist models) disagree with each other on how to resolve this, which is itself evidence the tension has not been solved, only variously described.
P: If two properties are logically incompatible in every other context they are attributed (an entity cannot simultaneously possess and lack the same capacity in the same respect at the same time), asserting that a single subject possesses both is a violation of non-contradiction, regardless of how the assertion is framed.
Christian doctrine holds Jesus was fully God (omniscient, omnipotent, incapable of sin) and fully human (limited in knowledge, limited in power, capable of genuine temptation) simultaneously, in one person. Mark 13:32 has Jesus state the Son does not know the day or hour of his own return, in apparent tension with the divine attribute of omniscience; Hebrews 4:15 asserts he was tempted “in every way, just as we are,” which requires a genuine possibility of failure, in tension with the divine attribute of impeccability. The standard resolution — that each nature retains its own properties without the properties mixing (the doctrine of the hypostatic union) — asserts the coexistence without explaining how a single subject can simultaneously know and not know the same fact, or be capable and incapable of the same failure, in the same respect. Asserting two incompatible predicates of one subject and calling the mechanism a mystery does not remove the contradiction; it names it and declines to resolve it.
Finally, all Christians need to understand the following about ‘winning’ as it pertains to reason:
P: A category boundary that is stated and applied consistently before a challenge arises is a definition; a category boundary that appears or shifts only in reaction to a specific counterexample, with no independent criterion offered, is not a definition but an evasion — and the difference between the two is whether the criterion predates the objection.
If a Christian, prior to any specific challenge, has a longstanding and consistently-applied position (e.g., “the creeds are the boundary of orthodoxy,” or “God is defined as necessary rather than contingent being”), engaging that position on its merits is required, not optional — dismissing it as a fallacy because it’s inconvenient is itself a rhetorical shortcut. But if a boundary or standard of evidence appears only after a specific counterexample is raised, is justified with no criterion beyond “that doesn’t count,” and would have shifted again had a different counterexample been raised instead, that shift is diagnostic of an unprincipled position — the position is being protected rather than defended.
AKA, Understand No True Scotsman (No real christian would..) and Moving The Goalpoasts (well now that you’ve said that, here’s my new stance) are failing the argument, they are fallacies of reason.
Additionally:
For its first three centuries, Christianity existed as a minority movement without centralized doctrinal authority. In 325 CE, Emperor Constantine convened the Council of Nicaea to resolve the Arian controversy and unify Christian doctrine across the empire, formalizing the Trinitarian position that became orthodox Christianity while several competing early sects — including various Gnostic and Arian communities — were declared heretical.
In 380 CE, Emperor Theodosius I’s Edict of Thessalonica made Nicene Christianity the official state religion of Rome, after which non-conforming Christian sects were actively suppressed. December 25 was established as a Roman solar holiday (the birthday of Sol Invictus) under Emperor Aurelian in the third century, and the church adopted this date for Christmas in 336 CE; many associated traditions (evergreen trees, gift exchange, midwinter feasting) predate Christianity and derive from earlier winter solstice observances.
1 Kings 7:23 describes a circular basin ten cubits in diameter and thirty in circumference — implying a value of pi equal to exactly 3, versus the actual value of approximately 3.14159. Leviticus 11:13-19 classifies bats among birds, though bats are mammals; Leviticus 11:20-23 describes flying insects as four-legged, though insects have six legs.
Genesis 1 places the creation of the earth before the creation of the sun, while astrophysics indicates the sun formed roughly 500 million years before the earth. The geographic distribution of species — kangaroos and koalas found only in Australia, lemurs only in Madagascar, kiwis only in New Zealand — has no plausible migratory explanation under a single-origin-point dispersal model from a Middle Eastern landing site roughly 4,000 years ago, but is consistent with continental drift and evolutionary divergence over millions of years.
According to Pew Research Center, the share of American adults identifying as Christian fell from about 90% in 1972 to 63% in 2021, with only about 49% of Millennials and Gen Z identifying as Christian. UK Christian identification has fallen from over 70% two decades ago to under 40% today. A 2004 John Jay College study commissioned by the U.S. Conference of Catholic Bishops found that between 1950 and 2002, roughly 4,392 Catholic priests in the United States were accused of child sexual abuse by approximately 10,667 individuals. A 2018 Pennsylvania grand jury report documented over 1,000 identified victims of abuse by more than 300 priests across six dioceses over several decades, alongside internal documentation of the abuse being systematically concealed. Christianity is waning, because it doesn’t stand up to the modern scrutiny of science.
