Mark D. Roberts is blogging here on Gospel reliability with particular reference to Misquoting Jesus. In the second section (here) he calculates the approximate number of possible variants in the Gospels and comes up with the figure 64 million. Allowing for the high estimate of 200,000 variants in Gospel manuscripts he comments that this is not very many.
Such use of numbers is something we have reflected on before (here). Statistics have long been in use in estimates by textual critics of the reliability of the NT transmission. Numbers of variants were important to Bentley and percentages to Westcott and Hort. More recently Ehrman has found the number of variants in the NT (200-400 thousand?) to be significant, but from a different perspective Norman Geisler would cite 99.5% accuracy for NT transmission.
One reaction could be to run from all use of numbers, but if we are not to be too dismissive we may at least ask what legitimate ways there are of using them.
