In her newest book, Pagels explores the history of John of Patmos' Book of Revelation. She outlines what we know about John of Patmos, what he was trying to say with his preaching, and how contemporaries may have responded. The second half of the book covers the history of Christianity in the first two centuries C.E., with emphasis on Pagels' favorite topic of disparate beliefs among early groups. She completes the book with a description of how the Bible Cannon was chosen, with some suggestions about why John of Patmos' Book of Revelation was the only apocalyptic literature included. Pagels' writing is clear and interesting, though a bit repetitive--especially if you've read some of her earlier works. If you're interested in early church history, especially the disparate groups of Christians, then this is the book for you. If you're interested in apocalyptic literature in early Christian history, then the first half of this book, and the tail end, is for you.
