How the Bible Was Changed: Verse-by-Verse Manuscript Evidence

The New Testament was not written in a single manuscript that has been continuously preserved. We have no original autograph manuscripts of any New Testament book. Every manuscript in existence is a copy — made by hand, by scribes, across centuries and continents. The earliest complete manuscripts of the New Testament date to the 4th century CE, approximately 300 years after Jesus. Biblical textual criticism is the academic discipline of comparing thousands of surviving manuscripts to reconstruct the most likely original text. Scholars have catalogued over 5,700 Greek New Testament manuscripts alone — and they differ from each other in more than 400,000 places. Most of these differences are minor: spelling variations, word order changes, grammatical adjustments. But some are theologically significant — entire passages that appear in later manuscripts but are absent from earlier, more reliable ones. Modern translations (NIV, ESV, NASB) mark many of these with brackets or footnotes noting: 'The earliest manuscripts do not include this verse.' This is not a Muslim accusation against Christianity. It is the documented conclusion of mainstream Christian biblical scholars, including conservative evangelicals like Bruce Metzger (Princeton Theological Seminary) and F.F. Bruce.

This divine promise of preservation, made explicitly for the Qur'an in Surah Al-Hijr, was not made for the earlier scriptures in the same way — and the manuscript evidence of the New Testament demonstrates why.

The most consequential interpolations are not narrative additions but doctrinal alterations — changes that directly affected foundational Christian beliefs about God and the nature of Jesus.

1. The Only Explicit Trinity Verse (1 John 5:7) — Added in the 14th Century

The King James Bible (KJV) reads at 1 John 5:7-8: 'For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. And there are three that bear witness in earth, the spirit, and the water, and the blood: and these three agree in one.' The italicised section — known among scholars as the Comma Johanneum — is the only place in the entire Bible where the Trinity is explicitly stated as three persons united as one. And it is absent from every Greek manuscript of the New Testament before the 10th century CE, with only four late manuscripts (dating from the 15th-16th centuries) including it — manuscripts known to have been influenced by the Latin Vulgate rather than independent Greek tradition. The evidence is unambiguous: - Absent from Codex Sinaiticus, Codex Vaticanus, Codex Alexandrinus, and all major early Greek manuscripts. - Absent from the early Syriac, Coptic, Armenian, and Ethiopian versions. - Not quoted by any Greek Church Father before the 10th century, even when defending the Trinity — an extraordinary omission if the verse existed. - Erasmus refused to include it in his 1516 Greek New Testament for this reason. - Jerome, who compiled the Latin Vulgate, himself noted its absence from the Greek sources.

The Comma Johanneum is not found in any Greek manuscript before the 10th century, nor is it cited by any of the Greek or Latin Church Fathers in their discussions of the Trinity.

The NIV, ESV, NASB, RSV, and NRSV all omit the Trinitarian phrase entirely or place it in a footnote. Only Bible versions derived from the late Textus Receptus — including the KJV — retain it. The only explicit biblical statement of the Trinity is a documented medieval addition.

2. 'He' Became 'God' in 1 Timothy 3:16

The King James Bible reads at 1 Timothy 3:16: 'And without controversy great is the mystery of godliness: God was manifest in the flesh.' This is one of the strongest direct statements of Jesus' divinity in the New Testament. The problem is that the oldest Greek manuscripts — including Codex Sinaiticus and the Alexandrian text tradition — read not 'God' (θεός, theos) but 'He who' (ὅς, hos): 'He who was manifested in the flesh.' The NIV translates: 'He appeared in a body.' The ESV: 'He was manifested in the flesh.' Neither says 'God.' How did 'He' become 'God'? In the uncial (capital letter) script used by early scribes, ΟΣ (hos, 'who') and ΘΣ (abbreviation for theos, 'God') differ by only a single horizontal stroke — a line added across the O to make a Θ, and a horizontal bar to create the nomina sacra abbreviation. Scholars believe a later scribe — either deliberately or in copying an already-altered manuscript — made this change, transforming an ambiguous pronoun into an explicit declaration of divinity.

The reading 'God' (θεός) appears to be a scribal alteration, perhaps made to express the divinity of Christ more emphatically.

3. 'Son of God' Added to the Opening of Mark (Mark 1:1)

The King James Bible opens Mark's Gospel with: 'The beginning of the gospel of Jesus Christ, the Son of God.' The phrase 'the Son of God' is absent from several important early manuscripts, including Codex Sinaiticus in its original hand. It appears to have been added to Mark's opening as a theological declaration of Jesus' status, shaping how the entire Gospel would be read. Modern critical editions mark it as uncertain. The NIV and ESV retain it but with a footnote noting the manuscript uncertainty.

Beyond individual verse alterations, textual critics have identified several significant narrative passages — complete stories and scenes — that appear in later manuscripts but are demonstrably absent from the oldest surviving texts.

4. Mark 16:9–20 — The Entire Resurrection Ending Is a Later Addition

This is perhaps the most significant finding in New Testament textual criticism. The Gospel of Mark, as it appears in the two oldest complete Greek manuscripts — Codex Sinaiticus (4th century) and Codex Vaticanus (4th century) — ends at verse 16:8, with the women fleeing from the empty tomb in fear. Verses 9–20, which include post-resurrection appearances of Jesus, instructions to preach the gospel, and the miraculous signs that will accompany believers (handling serpents, drinking poison), are absent from both of these manuscripts, from many early Latin manuscripts, from the Sinaitic Syriac manuscript, and from approximately 100 Armenian manuscripts. Eusebius of Caesarea (4th century) and Jerome (4th-5th century) both explicitly state that in their time, 'the accurate copies' and 'almost all the Greek copies' of Mark ended at 16:8. The vocabulary and writing style of 16:9-20 also differ noticeably from the rest of Mark, pointing to a different author. All major modern translations include the passage but mark it with a note such as: 'The earliest manuscripts and some other ancient witnesses do not have verses 9-20.'

The conclusion is unavoidable: the longer ending of Mark (16:9-20) was not written by the author of the rest of the Gospel.

5. John 7:53–8:11 — The Woman Caught in Adultery Was Added

The story of Jesus and the woman caught in adultery — containing the famous line 'Let him who is without sin cast the first stone' — is one of the most beloved passages in the Gospels. It is also absent from every manuscript of John before the 5th century. This includes: - Codex Sinaiticus, Codex Vaticanus, Codex Regius, and Papyrus 66 and Papyrus 75 — the oldest Gospel manuscripts. - Many early Greek Church Fathers, including Origen and Chrysostom, comment extensively on John chapters 7 and 8 but make no reference to this story. - In manuscripts where it does appear, it often occupies different locations — sometimes after John 21:25, sometimes inserted into the Gospel of Luke after 21:38 — indicating that it was a floating tradition inserted at different points by different scribes. Both the NIV and ESV include the passage but mark it with a note: 'The earliest manuscripts and many other ancient witnesses do not have John 7:53–8:11.'

6. Luke 22:43–44 — Jesus Sweating Blood Is Uncertain

The passage describing an angel strengthening Jesus in the Garden and Jesus 'sweating like drops of blood' is absent from Papyrus 75, Codex Vaticanus, Codex Alexandrinus, and other important early witnesses. It is present in Codex Sinaiticus and the majority of later manuscripts, but many manuscripts that do include it mark it with asterisks (indicating scribal doubt about authenticity). Some scholars believe it was added to emphasise Jesus' suffering and humanity in the context of doctrinal debates about his divine nature.

7. John 5:3b–4 — The Angel Stirring the Water

The explanation that 'an angel went down at a certain season into the pool, and troubled the water,' which gives the reason why people waited at the pool of Bethesda, is absent from Papyrus 66, Papyrus 75, Codex Sinaiticus, and Codex Vaticanus. It appears to have been added by a later scribe to explain the narrative. The NIV and ESV place it in brackets or a footnote.

Beyond the major passages above, textual critics have documented dozens of smaller but meaningful additions throughout the New Testament:

• Acts 8:37 — Philip's entire exchange with the eunuch ('If you believe with all your heart, you may') is absent from the earliest manuscripts. The NIV omits it; the ESV places it in a footnote. It appears to have been added to provide a formula for baptism.
• Matthew 17:21 — 'This kind does not go out except by prayer and fasting' is absent from Codex Sinaiticus, Codex Vaticanus, and other early witnesses. Omitted in NIV and ESV. Likely imported from the parallel passage in Mark 9:29.
• Matthew 6:13 — The Lord's Prayer doxology ('For yours is the kingdom, the power, and the glory forever') is absent from Codex Sinaiticus, Codex Vaticanus, and Codex Bezae. Omitted in NIV and ESV. Apparently added as a liturgical closing during early Christian worship.
• Acts 8:37 — The entire confession of faith is absent from the oldest manuscripts and appears only in later Western manuscripts from the 6th century onward.
• Matthew 23:14 — 'Woe to you, scribes and Pharisees, hypocrites! For you devour widows' houses' is absent from important early manuscripts and omitted in the NIV. Likely imported from the parallel passage in Mark 12:40.
• Luke 23:17 — 'For he must release one to them at the feast' is absent from many early manuscripts. The NIV omits it; the ESV includes it in brackets.
• Romans 16:24 — A closing benediction absent from major early manuscripts. Omitted in NIV and ESV.
• 1 Corinthians 14:34-35 — The instruction for 'women to remain silent in churches' appears in different locations in different manuscripts, suggesting it may have been a marginal note that was later incorporated into the text at different points by different scribes.

The documentary evidence above is not presented to ridicule sincere Christians or to dismiss the genuine spiritual wisdom that the Bible contains. Muslims believe the original Torah, Psalms, and Gospel were divinely revealed — and that portions of divine truth are still present in the Bible in its current form. The issue is whether the Bible in its transmitted state can be considered perfectly preserved, inerrant divine revelation.

The Qur'an establishes a testable criterion: a scripture truly from God would be free of internal contradictions and would be preserved intact. The Qur'an, revealed in the 7th century CE and memorised in its entirety by hundreds of thousands of Muslims in every generation since, has no manuscript variants of theological significance. The oldest surviving Quran manuscripts — dating to within decades of the Prophet's death — match the Quran recited today in mosques from Jakarta to Lagos to London, letter for letter.

This is what makes the Islamic position coherent: the Qur'an does not simply assert that the Bible was corrupted — it demonstrates it by the Bible's own internal evidence and invites comparison. The divine promise of preservation (Surah 15:9) was made specifically for the Qur'an, and that promise has been kept in a way that the historical record of the Bible's transmission does not match.
