Dan Wallace has now written a review of Bart Ehrman's Misquoting Jesus on the Aspire2 Blog. His review takes the subject from a different but complementary angle to mine. I limit myself to one quotation:
'Unfortunately, as careful a scholar as Ehrman is, his treatment of major theological changes in the text of the NT tends to fall under one of two criticisms: Either his textual decisions are wrong, or his interpretation is wrong. These criticisms were made of his earlier work, Orthodox Corruption of Scripture, which Misquoting Jesus has drawn from extensively. Yet, the conclusions that he put forth there are still stated here without recognition of some of the severe criticisms of his work the first go-around.'
