Has the Bible Been Changed? What Textual Scholars Actually Say

In the two oldest complete Bibles — Codex Sinaiticus and Codex Vaticanus, both fourth century — the Gospel of Mark ends at 16:8, with the women fleeing the empty tomb, "for they were afraid". The twelve verses that follow in most printed Bibles are absent.

Those twelve verses are not incidental. They contain the resurrection appearances in Mark, the Great Commission in Markan form, "he who believes and is baptized will be saved; but he who does not believe will be condemned", and the promise that believers "will take up serpents; and if they drink anything deadly, it will by no means hurt them" — the passage on which snake-handling churches in Appalachia were founded. Their vocabulary and style differ from the rest of Mark, and Eusebius and Jerome both note that the accurate copies of their day lacked them.

Nearly every modern translation now carries a note along the lines of "the earliest manuscripts and some other ancient witnesses do not have Mark 16:9–20". That the passage was added later is not a Muslim polemic; it is printed in the Bibles Christians buy.

"He who is without sin among you, let him throw a stone at her first" is probably the most quoted single line about Jesus (PBUH) outside the Sermon on the Mount. It is also almost certainly not part of John's Gospel.

The passage is missing from all the earliest Greek manuscripts of John. When it does appear, it wanders: some manuscripts place it after John 7:36, some at the end of John, and some in the Gospel of Luke after 21:38 — a strong sign of a free-floating tradition later inserted into a written text. Its vocabulary is closer to Luke than to John, and the flow of John 7 to 8 reads more naturally without it.

Bruce Metzger, a committed Christian scholar, wrote that the evidence for its non-Johannine origin is overwhelming. Many scholars nonetheless think the story itself may be an authentic early memory of Jesus (PBUH) that circulated orally before being written down — which is a fair and interesting position, and a different question from whether John wrote it.

The only verse in the Bible that states the Trinity explicitly — "the Father, the Word, and the Holy Ghost: and these three are one" — is a late Latin addition. It appears in no Greek manuscript before around the fourteenth century, is unquoted by the Greek fathers even during the Arian crisis when it would have been decisive, and is absent from the earliest translations.

Its entry into printed Bibles is well documented. Erasmus left it out of his first two editions of the Greek New Testament; under pressure, and on the appearance of one very late Greek manuscript that contained it, he included it in the third edition. From there it entered the Textus Receptus and the King James Version.

It has now been removed from the NIV, ESV, NRSV and NASB. A verse that shaped centuries of doctrinal argument is gone from the mainstream text, on the ordinary evidence of the manuscripts.

The most significant category is smaller and harder to see: places where the wording appears to have been altered to protect a doctrine. Ehrman's academic monograph The Orthodox Corruption of Scripture is devoted to it, and the examples are concrete.

In Luke 22:43–44, Jesus (PBUH) sweats "as it were great drops of blood" and is strengthened by an angel in Gethsemane — absent from several of the earliest and best manuscripts, and plausibly added against docetic groups who denied a real suffering body, or removed by scribes uncomfortable with a distressed Christ. In Mark 1:41, the earliest reading has Jesus (PBUH) "moved with anger" at a leper who asks for healing; most later manuscripts read "moved with compassion". In Luke 23:34, "Father, forgive them, for they know not what they do" is missing from major early witnesses. In John 1:18 manuscripts divide between "the only begotten Son" and "the only begotten God" — a variant with obvious doctrinal weight.

Two caveats are essential. Scholars disagree about several of these cases, and Ehrman's interpretation of the scribes' motives is contested by other textual critics who accept the same manuscript data. And in most instances the earlier reading is recoverable precisely because the evidence survives — the discipline works. Stating the variants as facts is legitimate; presenting every one as proven deliberate corruption is not.

The discussion usually focuses on the New Testament, but the Hebrew Bible has a parallel story. The Dead Sea Scrolls, discovered from 1947 and dating from roughly the third century BCE to the first century CE, showed that some biblical books circulated in more than one form: the scrolls of Jeremiah include a version substantially shorter than the traditional Hebrew text, matching the older Greek Septuagint translation. Samuel likewise appears in variant forms.

At the same time, the Isaiah scroll turned out to be remarkably close to the medieval Hebrew text copied a thousand years later — a striking testimony to careful transmission. The honest summary is that Hebrew scripture was transmitted with great care and, in places, in more than one recognised edition.

The conclusion the evidence supports is narrow and should be stated narrowly. Nobody can claim the biblical text has come down letter-perfect, unaltered by human hands; specific passages read by millions were demonstrably added centuries later. Equally, nobody can claim the Bible is a wholesale fabrication or that its message was invented at Nicaea: the core narrative is stable across the manuscript tradition, and the variants are visible precisely because so much evidence survives.

For Muslims the comparison is the substance of the argument. The Qur'an was memorised in full by many companions during the Prophet's (SAW) lifetime, recited publicly in daily prayer from the beginning, written down under his supervision, and standardised in a single official text under the third caliph within roughly two decades of his death. Its transmission has been oral and written together, with an unbroken chain of certified memorisers to the present. Manuscript scholars working outside Islam — Marijn van Putten's work on the Uthmanic archetype, for example — have argued that the surviving early Qur'anic manuscripts descend from one written archetype with remarkable consistency.

That does not by itself prove the Qur'an is from God, and it should not be presented as though it did. What it establishes is that the two books have different transmission histories, that those histories are documented, and that anyone comparing the scriptures is entitled to weigh them.

Bart Ehrman's Misquoting Jesus (PBUH) is the accessible introduction; his The Orthodox Corruption of Scripture is the technical argument. Bruce Metzger's A Textual Commentary on the Greek New Testament gives the manuscript reasoning verse by verse from a believing Christian scholar. For a Christian response to Ehrman, Daniel Wallace's Revisiting the Corruption of the New Testament accepts the data and disputes the conclusions — reading both is the only way to hold an informed view.

The manuscripts themselves are online: Codex Sinaiticus can be read page by page for free, and the footnotes in any modern study Bible will show you where the disputed passages are.
