Marc Brettler was on NPR yesterday promoting his new book, How to Read the Bible. You can listen to the interview here, but my main reason for linking to the page is to direct you to the excerpt from the book's introduction. (You'll have to scroll down a bit.)
How to Read the Bible is a thoughtful, easy-to-read book designed to present the historical-critical method to Jewish laypeople. It is not only for Jews or laypeople, however. I am currently in the middle of the book, and I'm finding it very engaging. It has also helped me come up with ideas for effective ways to present biblical criticism to my (mostly Christian) students.
