How Textual Criticism Actually Works
The figure of “400,000 variants” is real and often quoted to unsettle people. It stops being alarming once you know what a variant is, where they come from, and how the discipline resolves them.
What a “variant” is
A textual variant is any place where any manuscript differs from any other — a misspelling, a swapped word order, a missing article. With roughly 5,800 Greek manuscripts plus tens of thousands in other languages, a single slip that gets copied into two thousand later manuscripts is counted as one variant attested by two thousand witnesses. The total scales with the number of copies, not with the amount of corruption. A text preserved in only three manuscripts would have almost no variants — and almost no way to check itself.
Where they come from
Unintentional errors
Itacism — vowels and diphthongs that came to sound alike, so a scribe taking dictation writes the wrong one. Haplography (writing once what should be written twice) and dittography (the reverse). Homoeoteleuton — the eye jumps from one line-ending to an identical one further down and skips the text between. These account for the large majority of variants and almost never touch meaning.
Intentional changes
Scribes sometimes harmonised a Gospel to its parallel, smoothed rough grammar, added a clarifying phrase, or expanded a divine title out of reverence. A small number are doctrinally motivated — the Comma Johanneum (1 John 5:7) is the clearest case. These are the variants that matter, and they are exactly the ones the discipline scrutinises hardest.
The scale, honestly
What is actually in doubt
By the standard breakdown (Daniel Wallace and others): around 70% of all variants are spelling; the vast majority of the rest are meaningless for translation. Variants that are both meaningful and genuinely undecided are well under 1%. Wallace’s summary after decades of manuscript work: “no cardinal doctrine is jeopardised by any viable variant.” The two largest disputed passages — the longer ending of Mark (16:9–20) and the woman caught in adultery (John 7:53–8:11) — are footnoted in every serious modern Bible.
The method
External and internal evidence
External: the age of a reading’s witnesses, their geographic spread, and their text-type — the Alexandrian (early, generally spare), Byzantine (later, fuller, the majority), and Western (early, freer) families. Internal: which reading best explains the origin of the others; the harder reading is usually earlier (scribes smooth, they rarely roughen); the shorter reading often is too. Modern editions weigh both — “reasoned eclecticism.” For the Catholic Epistles and Acts, the CBGM (Coherence-Based Genealogical Method) now maps how manuscripts relate and feeds the NA28/ECM text.
Ehrman’s own position
The gap between the book and the takeaway
Misquoting Jesus (2005) left many readers thinking the text is hopelessly compromised. In the same book’s appendix Bart Ehrman agrees with his teacher Bruce Metzger that “essential Christian beliefs are not affected by textual variants.” His scholarly claim is that we cannot always be certain of the original wording in a given verse — not that doctrine hangs on the uncertainty.
💡 How Textual Criticism Works — Reasonable Summary“A variant is any difference in any manuscript; the count is high because the manuscripts are many, not because the text is corrupt. Most variants are spelling and slips of the eye; a minority are deliberate scribal changes; the ones that are both meaningful and undecided are under 1%, and none carries a doctrine. Scholars weigh the age, spread, and family of the witnesses against which reading best explains the rest, and print the result in the standard critical editions. Even Bart Ehrman grants that no essential Christian belief turns on a textual variant.”
