Darrell Bock calls out Bart Ehrman on his bias here. Bock comments on Ehrman’s The New Testament: An Historical Introduction. I have read this book cover to cover so I can attest to Bock’s lament. Ehrman’s MO is to prejudice his conclusions with, not so much to what is said, but on what is not said (Ehrman does this as well in his popular textual critical books). In that blog article, Bock takes the example of the author of Mark and demonstrates Ehrman’s lack of scholarly fairness with the evidence.
