This is a plug for Bart Ehrman. He's a hot topic right now in the pop realm of biblical scholarship. I say pop realm because those who have gone to seminary or have engaged serious biblical scholarship find most of what he says to be standard information.
We are watching his lecture series Lost Christianities (he has a book by the same name) in our Eclectic Mass spirituality group. In case you haven't figured it out, we're all fans.
For those who want to know more about what Erman's all about, here is a list of interviews with him on NPR. Enjoy!
