The Bibliographic / Manuscript Test
We have 5,800 Greek copies of the New Testament. Caesar's war diary survives on ten. Do the math.
Grounded in the research on the bibliographic test
the test
We don't have the original New Testament. Nobody has the first ink Paul or John put down. So how do you trust the text? The bibliographic test is the standard classicists already use on every ancient document: count the surviving copies, and measure the gap between the original and the oldest copy you've got. More copies plus a shorter gap equals a text you can reconstruct with confidence. Apply that same yardstick to the New Testament, the argument goes, and it laps the field.
where it comes from
Josh McDowell hammered it into the mainstream in 1972 with 'Evidence That Demands a Verdict,' borrowing the framework from textual scholars like F.F. Bruce. But the test itself isn't a religious invention. It's just how historians weigh Tacitus, Herodotus, or Homer. The whole move is to refuse special pleading: judge the Gospels by the exact criteria you'd judge Caesar's 'Gallic Wars' by, and see what happens. McDowell's bet was that the New Testament wins on its own neutral terms.
