More than worthwhile
It's been over a year, so my memory of much of this book is fuzzy. That said, John Howard Yoder's contribution, Practicing the Rule of Christ, is worth more than its weight in gold. The article was originally written as a study guide on forgiveness, complete with study questions. Some additional material was added a bit later in a more standard essay form. This article was, without any doubt, the most provocative thing I've read in quite some time. The ideas from it still swirl around in my head on a regular basis.Plenty of other good stuff on Christian conception of virtues as well.
