Jesus for the Non-Religious
John Shelby Spong
If you believe in the inerrancy of the bible, this book is not for you, but if you are interested in biblical scholarship, this is an interesting study. Spong is a retired Episcopal bishop and has written several books on his interpretation of the bible. He writes well and presents his arguments in a concise way. You probably won't agree with all he writes, but you will find it thought provoking.
