I agree with LMS "Book worm" who said: "I was very disappointed by this book. I expected a lot more after reading "Pagan Christianity" "Reimagining Church" and the many positive reviews on this site. ... In my opinion, this is not one of Viola's strongest works. This book is okay. But in my opinion, there's nothing here that's earth shattering. My advice would be to skip this book and pick up a copy of "Pagan Christianity" instead. ...
