This book took me a long time to read, not due to any lack of interest, but because of the detail and complexity of the subject. But Ehrman has a fluid and enviably lucid writing style that helps make the convolutions of scriptural history and analysis approachable. He is even-handed, concerned with uncovering truth, not with promoting or debunking any particular religious viewpoint.
The book is not an easy read and if you are of the belief system that the Bible has "no errors" you will be unlikely to struggle through the data that the author includes showing that there have been many errors and changes made to the New Testament over the years.
The author discusses the conflicting reports in Matthew, Mark, Luke and John. He discusses how and why these differences could have occurred.
If you stick with it, it is well worth reading. I found the last few chapters to be of particular interest as they address changes made to devalue women and to fan the flames of hatred of the Jews.
Excellent book, disproves Justice Scalia's notion that atheists shouldn't be teaching bible classes. The author does come down in favor of several interpretations of scripture.
Not for Chiritians who are afraid to be challanged.
