The original documents written by Moses, Isaiah, Paul or John no longer exist. Like all ancient writings, they were copied by hand, and those copies were copied again. So how do we know that the Bible we read today matches what was first written? The answer lies in the story of manuscripts, scribes and careful scholarship.
Writing materials in the ancient world
The Bible's books were first written on materials such as:
- Papyrus — sheets made from the papyrus plant, common in Egypt and around the Mediterranean.
- Parchment — prepared animal skins, more durable than papyrus.
Early texts were written on scrolls. By the second century, Christians increasingly used the codex — pages bound together like a modern book — which was easier to carry and to search.
Copying the Old Testament
Jewish scribes treated the copying of Scripture with great seriousness. Over centuries, scribes developed careful methods. Later scribes known as the Masoretes (active roughly between the 6th and 10th centuries AD) added vowel markings and notes, and counted letters and words so that errors could be detected. One of the oldest complete Hebrew Bibles, the Leningrad Codex, dates from about AD 1008.
The Dead Sea Scrolls
In 1947, a shepherd discovered jars containing ancient scrolls in caves near Qumran, beside the Dead Sea. Over the following years, thousands of fragments were found, including portions of every Old Testament book except Esther.
The most famous is the Great Isaiah Scroll, dating from around the second century BC — about a thousand years older than the oldest Hebrew manuscripts previously known. When scholars compared it with later copies, they found that the text had been passed down with remarkable care. Most differences were small matters of spelling and wording.
Copying the New Testament
The New Testament is the best-documented writing from the ancient world. Scholars have catalogued well over 5,000 Greek manuscripts of all or part of the New Testament, plus thousands of early translations into Latin, Syriac, Coptic and other languages, and many quotations in the writings of early church leaders.
Some important early manuscripts include:
- Papyrus 52, a small fragment of John 18, often dated to the second century — one of the earliest known New Testament fragments.
- Codex Sinaiticus and Codex Vaticanus, nearly complete Bibles in Greek from the fourth century.
By comparison, many classical works of Greek and Roman literature survive in only a handful of copies, often written many centuries after the originals.
What about copying errors?
Hand copying inevitably produced variations — a misspelled word, a skipped line, a changed word order. Scholars in the field called textual criticism compare thousands of manuscripts to identify the original wording. Because there are so many manuscripts from different regions and centuries, errors in one copy can usually be identified by comparing it with others.
The great majority of variations are minor and do not affect meaning. Where significant differences exist, modern Bibles often include a footnote, such as "Some manuscripts add…". No central Christian belief depends on a disputed passage.
From manuscripts to printing
In the 15th century, Johannes Gutenberg's printing press transformed the copying of Scripture. The Gutenberg Bible (around 1455) was one of the first major books printed with movable type. Printing meant that Bibles could be produced accurately in large numbers for the first time.
Why this matters
Christians believe God not only inspired Scripture but also preserved it through the faithful work of many generations. The evidence of manuscripts gives readers good reason for confidence that the Bible we read today faithfully reflects what was originally written.
