I've been thinking a little bit more about the Wright vs. Ehrman exchange at SBL. I think that it is probably worth observing that Ehrman was in fact the only person who maintained that there was a logical link between any doctrine of inspiration and the need to have particular words from God for such a doctrine to work. Thus, though in other respects he may seem the furthest from the classic evangelical position, in this respect he was the closest.
I'm now a third of the way through his book Misquoting Jesus. He has had to suffer what many an author has experienced, which is to find that the publisher has managed to put the Hebrew on the cover upside down. Fortunately, it is only the background and so it does not stand out too badly. The Hebrew is obviously a Dead Sea Scroll (CD?), but, unusually, nothing is said about the cover design.
I disagree with much of the general picture that Ehrman is painting, in particular the quantity of change that he suggests went on in the text early on (e.g. suggestions that there may have once been versions of John that lacked 1:1-18 or ch. 21). However, there is good coverage of much material. He emphasises the importance of written scripture for early Christians (even if they couldn't all read it) and affirms that 1 Tim. 5:18 does cite Luke 10:7 as scripture (p. 31).
Strangely he seems to think that since Galatians was written to a number of churches Paul must have made multiple copies so that there was no single autograph (pp. 58-60). I find it rather unlikely that the letter carrier would actually carry multiple copies when the letter could be reproduced locally. Do we have any evidence of multiple copies of letters being carried by a single individual?
