The Bible has been copied, translated and read for thousands of years.

So a reasonable question is:

Has the Bible changed along the way?

The most accurate answer is yes in some senses, but not in the way the question is sometimes imagined.

Ancient handwritten copies do contain differences. English translations have changed as language and scholarship have developed. And different Christian traditions do not all contain exactly the same collection of Old Testament books.

But that is different from saying that somebody repeatedly rewrote the whole Bible and replaced the earlier version.

Because large numbers of ancient manuscripts survive, scholars can compare them and study where differences occurred.

We do not have the original handwritten copies

The biblical books were written long before printing presses or digital files.

The original documents — sometimes called the autographs — have not survived.

That is not unusual for literature from the ancient world.

Instead, what survives are handwritten copies, copies of copies, ancient translations and quotations from biblical texts.

For the New Testament in particular, thousands of Greek manuscripts and many more manuscripts in other ancient languages allow scholars to compare how the text was transmitted.

That comparison is called textual criticism.

Did copying by hand introduce differences?

Yes.

Imagine copying an entire book by hand.

Even a careful copyist could:

• miss a word;
• repeat a word;
• spell something differently;
• accidentally skip a line;
• change word order;
• clarify wording;
• occasionally add an explanatory phrase.

These differences are called textual variants.

Most are small.

Some are simply spelling or word-order differences that make little or no difference to the meaning.

Others are more interesting and require careful study.

That is why scholars compare manuscripts rather than assuming every surviving handwritten copy is identical.

Were any changes more substantial?

Yes, there are some passages where the manuscript evidence shows more significant differences.

Two well-known New Testament examples are:

• Mark 16:9–20
  Some of the earliest surviving manuscripts of Mark finish at Mark 16:8, while later manuscripts contain the longer ending.
• John 7:53–8:11
  The story of the woman caught in adultery does not appear in some early manuscripts and occurs in different places in others.

Modern Bible translations normally make readers aware of cases such as these with footnotes or brackets.

That transparency is important.

Rather than hiding the evidence, translators show readers where the surviving manuscripts differ.

Does that mean we cannot know what the New Testament originally said?

The existence of differences may initially sound worrying.

But manuscript comparison works partly because there are so many copies to compare.

If one manuscript contains a wording that hundreds of others do not, scholars can investigate:

• how old the manuscripts are;
• where they came from;
• which reading best explains the others;
• whether a copying mistake is likely;
• how the wording was quoted by early Christian writers.

Scholars can therefore identify places where the text is uncertain rather than simply guessing.

Different critical editions occasionally make different judgements about particular readings, which is one reason textual criticism remains an active academic field.

Is the Old Testament transmission exactly the same story?

No.

The textual history of the Old Testament — or Hebrew Bible — is more complicated.

Ancient evidence shows that some biblical books circulated in more than one textual form.

The Dead Sea Scrolls, the traditional Hebrew text later known as the Masoretic Text, and the ancient Greek translation known as the Septuagint sometimes preserve different readings.

In certain books, the differences are relatively small.

In others, such as Jeremiah and Samuel, ancient textual traditions can differ more noticeably.

That means scholars studying the Old Testament are sometimes dealing not just with copying mistakes, but with evidence that slightly different editions of a book circulated in antiquity.

This is an important distinction and one reason simplistic claims that “every manuscript says exactly the same thing” are not historically accurate.

Have people deliberately changed the Bible?

Sometimes scribes appear to have made intentional changes.

These might include:

• making an awkward sentence easier to understand;
• harmonising one Gospel passage with another;
• adding explanatory wording;
• updating a place name;
• attempting to resolve an apparent difficulty.

Other changes happened accidentally.

The important point is that we often know these changes occurred because different manuscripts survive.

A change in one branch of the manuscript tradition can be compared against readings preserved elsewhere.

So textual variation is not simply evidence that the Bible was changed.

It is also part of the evidence scholars use to trace how the text was transmitted.

Has translation changed the Bible?

Translation creates another kind of difference.

The Bible was originally written mainly in Hebrew, Aramaic and Greek, not English.

Every English Bible therefore involves thousands of translation decisions.

For example, a translator may have to decide whether to preserve an ancient expression literally or communicate its meaning in more natural English.

That is why the NIV, NLT, ESV and KJV sometimes phrase the same passage differently.

It does not normally mean they are translating completely different Bibles.

They are often making different English choices from the same or very similar underlying ancient texts.

Our guide to why there are so many Bible translations explains how those translation choices work.

You can also explore Eden's Bible translations guide to compare different approaches.

Why do older and newer Bibles sometimes differ?

There are two main reasons.

English has changed

The King James Version was first published in 1611.

English vocabulary and grammar have changed considerably since then.

Modern translations therefore use language contemporary readers are more likely to understand.

Scholars have access to more manuscript evidence

Discoveries and advances in manuscript study mean modern translators can draw on evidence that was not available to translators several centuries ago.

This can occasionally affect a verse or phrase.

Modern editions usually indicate important differences in footnotes rather than pretending the evidence does not exist.

Has the number of books changed?

This is another question that is sometimes confused with changes to the wording.

Different Christian traditions contain slightly different Old Testament collections.

Most Protestant Bibles contain 66 books.

Catholic Bibles contain additional books traditionally called the Deuterocanonical books, while Orthodox traditions have some further differences.

The 27-book New Testament is shared across these major Christian traditions.

So if two Bibles contain different numbers of books, that does not necessarily mean somebody recently removed or added material.

It reflects much older differences in how Christian communities received particular Jewish writings.

So, has the Bible been rewritten?

That is too simple a description of the evidence.

A more accurate picture is:

Biblical texts were copied by hand for centuries. Differences arose. Multiple ancient textual forms sometimes existed. Scholars compare the surviving evidence to understand that history and reconstruct the earliest recoverable text.

There are places where the precise original wording remains debated.

There are also passages where ancient versions differ meaningfully.

Being honest about those points gives us a much clearer picture than either claiming that every manuscript is identical or suggesting that the Bible was freely rewritten beyond recognition.

Can I see these differences in a modern Bible?

Often, yes.

Look at the footnotes.

A modern Bible may say things such as:

“Some manuscripts...”

“The earliest manuscripts...”

or

“Some ancient witnesses...”

Those notes give ordinary readers a glimpse into the work behind the translation.

Rather than being a reason to ignore the Bible, they can be an invitation to look more closely at its history.
