The Reliability of Scripture #2

Skeptics often ask a fair question: even granting that ancient authors wrote what became the Bible, how do we know the text hasn’t drifted or been corrupted over the centuries of hand-copying before printing existed? This is the domain of textual criticism, the discipline of comparing surviving manuscripts to reconstruct what the original authors most likely wrote.

The Argument

The New Testament is, by a wide margin, the best-attested document from the ancient world. Over 5,800 Greek manuscripts survive, along with tens of thousands more in Latin, Coptic, and other languages, some fragments dating within decades of the autographs — compared to a handful of copies, centuries removed from the original, for works like Caesar’s Gallic Wars or Homer’s Iliad. The sheer volume of manuscripts allows scholars to cross-check variants against one another with a precision unavailable for any other ancient text. The Old Testament’s reliability was dramatically confirmed by the Dead Sea Scrolls, discovered in 1947, which included copies of Isaiah roughly a thousand years older than previously known Hebrew manuscripts and matched the received text with remarkable consistency. Luke explicitly describes investigating eyewitness sources for his gospel (Luke 1:1-4), reflecting a self-conscious concern for historical accuracy rather than legend.

Common Objections

Critics rightly note that the manuscripts do contain hundreds of thousands of variants — though the overwhelming majority are spelling differences, word-order changes, or obvious scribal slips that affect no doctrine, and no variant reading puts any core Christian teaching in doubt. A smaller set of genuinely disputed passages (such as the longer ending of Mark or the story of the woman caught in adultery) are openly flagged in modern study Bibles rather than hidden, which is itself evidence of transparent scholarship rather than a “changed” text.
