Step 4 of 9 · History
Can we trust the New Testament?
In brief
Two questions sit here. The text: with more than 5,500 Greek manuscripts, early translations and quotations, scholars can reconstruct what the New Testament authors wrote with high confidence, while openly marking passages that are later additions. The content: the Gospels are ancient biographies written within living memory of Jesus, and they can be tested like other ancient sources.
The 2-minute version
No original manuscript of any ancient book survives, the New Testament included. What survives is a copying tradition, and for the New Testament it is unusually large: the institute in Münster that catalogues it reports more than 5,500 Greek manuscripts, alongside early translations and quotations. More copies mean more variant readings, but also more ways to check them. Most differences are spelling and word order; a few are significant and are openly marked in modern Bibles. Reliable copying is not the same as reliable history, so the second question is about the Gospels themselves. They were written within the lifetime of people who knew Jesus; their titles are attested early; and second-century writers such as Papias and Irenaeus preserve traditions about their authors. They differ in detail, as ancient biographies do, and those differences deserve honest handling rather than forced harmony. The conclusion is modest and strong: we have good access to what the earliest Christians reported.
The strongest objection
Even if the words were copied faithfully, the content is not thereby reliable: the Gospels are formally anonymous, were written decades after Jesus by authors who were probably not eyewitnesses, depend on one another, and disagree on details such as the resurrection-morning accounts.
A response
“Anonymous” does not mean authorless. The Gospel titles are attested early and consistently, and second-century writers preserve specific traditions about who wrote them. Scholars still debate those traditions, and the site's article on the authors weighs them rather than assuming them.
The Gospels are related to one another, not four independent transcripts, and they do differ in detail. Differences of that kind are normal in ancient biography; the site's article on alleged contradictions works through the hard cases rather than harmonising them away.
Take the objection further: Who Wrote the Four Gospels?
The evidence
From Scripture
- Luke 1:1–4 — Luke's preface on eyewitness tradition and careful investigation.
- John 19:35; 21:24 — The Gospel's own claim to rest on witness testimony.
- 1 Corinthians 15:3–8 — Tradition that Paul received, earlier than any written Gospel.
From history
- The manuscript count. From the institute that catalogues Greek New Testament manuscripts.
“more than 5500 manuscripts of the Greek New Testament are known”
- The earliest complete New Testament. Codex Sinaiticus is fourth-century; earlier witnesses exist but are fragmentary.
“including the oldest complete copy of the New Testament”
- A correction on P52. The famous John Rylands fragment of John 18 is often dated to about AD 125. Its holding library gives its first editor's date of 100–150 CE and notes newer work favouring a later date.
“Recent research points to a date nearer to 200 CE”
- Second-century tradition on Mark. Papias, preserved by Eusebius, links Mark's Gospel to Peter.
“Mark, having become the interpreter of Peter, wrote down accurately, though not in order, whatsoever he remembered of the things said or done by Christ”
