This book is essentially an abbreviated history of where all of the common practices (outside of Christmas and Easter) of the Protestant church came from. I felt that the author made every effort to present the facts as cleanly as possible.That said, you probably noticed that many reviewers are very critical of the author's "opinions", but I got the impression that he was very up front about what was opinion and what was fact, and most of the disturbing parts of this book are undeniable facts. This is a very important book for Christians to read.P.S. - If you liked Shane Claiborne's "Irresistable Revolution", you will like this book. Together with "Reimagining Church", it's a more paced, scholarly verison of the same basic concepts.
