Let's see whether you remember any of this from Sunday or Hebrew school: Different New Testament writers disagree on when Jesus died and how he went to his death, whether with serene self-control or in fear. Some of those writers forged the names of famous Christian apostles on their works. The account of the Israelites conquering the promised land in the Hebrew Bible is almost certainly fanciful, not historical.
Those statements are all matters of scholarly consensus. You learn such things if you go to seminary or divinity school, says Bart Ehrman, but pastors usually don't pass them on in sermons or religious-education classes - and as a churchgoer, I can attest that that's true. So Erhman, a University of North Carolina religion professor, has published "Jesus, Interrupted," a rundown of what scholars have believed and taught about the Bible, in some cases for a century or more, using the "historical-critical" approach to scripture rather than a purely pious one.
