According to Daniel Wallace, in debate with Bart Ehrman:
We have as many as eighteen second-century manuscripts (six of which were recently discovered and not yet catalogued) and a first-century manuscript of Mark’s Gospel! Altogether, more than 43% of the 8000 or so verses in the NT are found in these papyri. Bart had explicitly said that our earliest copy of Mark was from c. 200 CE, but this is now incorrect. It’s from the firstcentury. I mentioned these new manuscript finds and told the audience that a book will be published by E. J. Brill in about a year that gives all the data. (In the Q & A, Bart questioned the validity of the first-century Mark fragment. I noted that a world-class paleographer, a man who had no religious affiliation and thus was not biased toward an early date, was my source.
Daniel Wallace adds in the comments section:
Friends, let me clarify a couple of things. First, the Mark manuscript is just a small fragment. Second, I didn’t discover it; I make no claims whatsoever for having done so. Third, exact news of the fragment will have to await its publication about a year from now.
The way this is being described suggests we are not dealing with another 7Q5 – or at least I hope not – but something clear cut. On Joel’s blog Matthew Hamilton adds this:
From what I’ve been able to glean there are now in the Green Collection 7 unpublished NT papyri
1. 2nd century frg. with Hebrews 1
2. 2nd century frg. with I Corinthians 8-10
3. 2nd century frg. with Matthew
4. 2nd century frg. with Romans 8-9
5. 2nd century frg. with part of a Pauline Epistle, from what I know it is from Hebrews
6. 2nd century frg. with Luke
7. 1st century frg. with Mark
Rearding Mark Stevens question as to where they were found, iIt appears most of these have been recently extracted from mummy cartonnage, but I don’t know any details as to where these were found
Obviously, given the lack of information, it is difficult to know what to make of all this at the moment. So, can anyone shed more light…?
