PROBLEMS: There was nothing wrong with the examples Foster selected, but they didn't grab me as much as other Renovare books have. Perhaps I'd rather read each person's own words than read about that person's life. Also, the binding on my book broke. I don't know if that is a problem or just happened to me.
POSITIVES: For me, the joy of this book was in the appendix and extra material. Foster gives us one appendix of critical turning points in church history and another of notable figures and significant movements in church history. He begins each chapter with a chart from the time of Jesus to present that lists significant people, movements, and dates related to that tradition.
CONCLUSION: The extra material is easily worth the cost of the book. The chapters are just the added bonus on this one. I've returned to these charts for reference time and time again.
Foster uses modern and historical/mythical persons to flesh out the strengths he ascribes to each branch of protestantism. While this approach will test readers who look down on the stories of the saints of old (he relates St. Francis' reasoning with a wild wolf in one chapter) if you can put aside modern protestant prejudices against christian mythology you'll be much the better for it.
I found the book to be a refreshing approach to integrating the major movements in Christianity. I am more mindful of the traditions of faith I did not grow up in and am attempting to incorporate their strenghts into my experience of Jesus Christ.
