Why do Textual Variations Exist in Scripture?
Question 1002
When comparing different Bible translations, readers sometimes discover that verses present in one translation appear in footnotes or brackets in another—or are absent entirely. These differences can unsettle believers who wonder whether something has been “removed” from Scripture. Understanding how textual variations arise and how scholars handle them actually strengthens confidence in the Bible’s reliability rather than undermining it.
Why Textual Variations Exist
Before the invention of the printing press in the fifteenth century, every copy of Scripture had to be written by hand. Scribes copying manuscripts worked with extraordinary care, often in dedicated scriptoriums where accuracy was paramount. Nevertheless, over centuries of copying, small variations inevitably crept into the manuscript tradition. These variations arose through several mechanisms.
Some variations resulted from simple human error. A scribe might accidentally skip a line when two consecutive lines ended with the same word (a phenomenon called homoeoteleuton), or his eye might jump from one occurrence of a phrase to another, omitting the material between them. Occasionally, a scribe might mishear when texts were dictated, writing a word that sounded similar but differed in spelling or meaning.
Other variations arose from intentional changes, though usually with good motives. A scribe might add a clarifying note that later copyists incorporated into the main text. Parallel passages might be harmonised—for example, a scribe copying Matthew’s account of an event might unconsciously add details from Luke’s version. Liturgical readings sometimes added introductory phrases like “Jesus said” that could become part of the text in subsequent copies.
The remarkable truth is not that variations exist but that they are so limited. Despite being copied by hand for fourteen centuries, the New Testament text remains stable across thousands of manuscripts. The vast majority of variations involve spelling differences, word order changes, or other minor matters that affect neither translation nor doctrine.
The Manuscript Evidence
The New Testament possesses an embarrassment of riches when it comes to manuscript evidence. We possess over 5,800 Greek manuscripts, ranging from small fragments to complete New Testaments. The earliest fragments date to within decades of the originals—Papyrus 52, a fragment of John’s Gospel, dates to approximately AD 125, within a generation of John’s writing. By contrast, the earliest manuscripts of most classical Greek and Roman works date to nearly a millennium after the originals.
Beyond Greek manuscripts, we possess thousands of copies in ancient translations: Latin, Syriac, Coptic, Armenian, Georgian, Ethiopic, and others. Additionally, the church fathers quoted Scripture so extensively that virtually the entire New Testament could be reconstructed from their writings alone.
This abundance of evidence allows textual critics to compare manuscripts, identify variations, and determine with high probability what the original authors wrote. When manuscripts disagree, scholars weigh factors like the age and quality of the manuscripts, the geographical distribution of readings, and internal considerations such as which reading best explains the origin of the others.
Significant Textual Variations
While most textual variations are inconsequential, some affect larger passages and deserve attention. Understanding these helps believers engage honestly with the evidence while maintaining confidence in Scripture’s reliability.
Mark 16:9-20, the longer ending of Mark’s Gospel, does not appear in our two oldest and most reliable manuscripts (Sinaiticus and Vaticanus). Early church fathers like Eusebius and Jerome noted that most Greek manuscripts they knew lacked these verses. The passage also contains vocabulary and style different from the rest of Mark. Most scholars conclude that Mark’s Gospel originally ended at verse 8, with the longer ending added later to provide a more satisfying conclusion. The theological content of the longer ending, however, finds support elsewhere in Scripture—Jesus did rise, did appear to His disciples, and did commission them to preach the gospel.
John 7:53-8:11, the account of the woman caught in adultery, presents a similar situation. It appears in various locations across different manuscripts—some place it after John 7:52, others after John 7:36, 7:44, or 21:25, and some manuscripts insert it into Luke’s Gospel. The earliest and best manuscripts of John lack it entirely, and the passage uses vocabulary foreign to John’s style. Yet the story itself bears the marks of authentic tradition about Jesus—it aligns perfectly with His character and teaching elsewhere in the Gospels. Most scholars believe it preserves a genuine early tradition about Jesus even if John did not write it.
1 John 5:7-8 in the KJV contains an explicit Trinitarian statement (the “Comma Johanneum”): “For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.” This reading appears in only a handful of very late Greek manuscripts, all apparently influenced by Latin texts. It originated as a Latin marginal gloss that entered the text tradition. The verse as it stands in modern translations (“For there are three that testify: the Spirit and the water and the blood; and these three agree”) remains fully inspired Scripture, and the doctrine of the Trinity rests firmly on numerous other passages.
How Modern Translations Handle Variations
Responsible modern translations employ transparent practices when handling textual variations. The ESV, NASB, NIV, and similar translations follow the best available manuscript evidence, typically basing their text on the Nestle-Aland Greek New Testament or the United Bible Societies’ text. When significant variations exist, they note them in footnotes or brackets.
This transparency actually serves readers well. Rather than hiding textual questions, modern translations honestly acknowledge them while still presenting a readable text. A reader encountering Mark 16:9-20 in the ESV, for example, will find it printed with a note explaining the manuscript evidence. This allows readers to engage the evidence directly rather than remaining ignorant of the issues.
Nothing has been “removed” from Scripture by modern translations. Rather, modern translations have sought to present what the original authors actually wrote, as best we can determine from the manuscript evidence. Passages that were added during the transmission process—even if they contain good theology—were not part of the inspired original text.
Why This Strengthens Confidence
Far from undermining biblical authority, the study of textual variations actually demonstrates the remarkable preservation of Scripture. Despite centuries of hand-copying across multiple continents and language families, the New Testament text remains essentially stable. The variations that do exist are identifiable precisely because we possess so many manuscripts to compare.
Consider the implications: if we possessed only one manuscript of the New Testament, we would have no way of knowing whether that single copy contained errors or additions. The abundance of manuscripts—with their variations—actually allows us to work back toward the original with confidence. The variations are not a bug in the system; they are evidence of the preservation process itself.
Moreover, no Christian doctrine depends on any textually uncertain passage. The deity of Jesus, His virgin birth, atoning death, bodily resurrection, and coming return are all taught in passages with rock-solid manuscript support. The great truths of the Christian faith remain entirely secure regardless of how we resolve any particular textual question.
Conclusion
Textual variations in Scripture, properly understood, witness to God’s providential preservation of His Word rather than casting doubt upon it. The science of textual criticism allows scholars to identify variations, weigh the evidence, and determine with high probability what the biblical authors originally wrote. Modern translations that follow this evidence are not “removing” verses from Scripture but seeking to present the text as God originally inspired it.
Believers can read their Bibles with confidence, knowing that the text before them faithfully represents the apostolic witness to Jesus. The message of salvation—that God loved the world and gave His Son so that whoever believes in Him might have eternal life—comes through with perfect clarity in every faithful translation, whether ancient or modern. Our trust rests not in the perfection of any transmission process but in the God who inspired His Word and has faithfully preserved it for His people.
