Forged: Writing in the Name of God, why the Bible's Authors are not who we think they are, by Bart Ehrman. According to the reviews on amazon, none of the information in it is new, but it was new to me. I knew in a general sense that the Bible had been codified hundreds of years after Christ's death, and that there was controversy over what to put in, but I didn't realize the extent of the bogus material floating around during the first few centuries.
As the title suggests, some of the Bible was not written by the people credited with it. Not all, but some: the gospels, Timothy 1&2, Peter 1&2, Corinthians 3, Acts, and the Apocalypse. The basis for discrediting author attribution is mainly the mention of events too recent to be known to the supposed authors, and theological points that contradict Paul but are in line with later theology.
Some of the most virulent anti-women stuff is in the two Timothy letters, so I was glad to see them discredited even though I don't have any plans to become a preacher. I want to like Christ and his followers, even if I don't believe any of the supernatural stuff in the fairy tale. Bart Ehrman redeems them quite a lot in this book.
The writing is a bit repetitive, especially in his frequent insistance that forgery was neither common nor condoned during the period the Bible was being written. I got the impression that there's some great war going on in scholarship and he believed if he shouted often enough his side might win. But... if you were to pick up the book and read a single chapter, it would make sense to you because some of the repetition sets the stage for his look at individual cases.
Chapter Four should really have been Chapter One, since he refers to it so often in the earlier chapters. This is the chapter in which he debunks the alternative theories one by one: no, an ignorant Aramaic-speaking fisherman couldn't have dictated the gospel in perfect academic Greek style, no, scribes wouldn't have been able to make up stuff with the author's content yet in their own style, no, it wasn't common practice for followers of a teacher to use the teacher's name for their own work, etc.
I recommend it with the caveat that a straight through cover-to-cover read could be a bit tedious and repetitive. If you have an interest in how the Bible came to be and what it's really made of, you'll overlook the flaws and find this book fascinating, as I did.
