The Pharisees' Guide to Total Holiness by William L. Coleman. I found the book on a book shelf in the closet at church. I was clearing the shelf off to take into my office for all of my books. This is one book that came with me into the office.
I have never heard of this author, so I hesitate recommending this book, but so far it has been pretty good. I just finished chapter 5 and I am plowing ahead into chapter 6.
It is keeping my attention (which means something for a guy with such extreme ADD). It isn't a perfect book: there have been a couple of things that I don't quite agree with how they were phrased, but overall I think this guy is onto something. It might be a tad bit outdated, but it really does offer a good synopsis of who these Pharisees were and what they were all about.
