Subverting Hatred: The Challenge of Nonviolence in Religious Traditions by Daniel L. Smith-Christopher [Orbis Books, 2007] (Paperback) 10th Anniversary [Paperback]
This book is a collection of academic-style papers written on peaceful traditions in various faiths. The articles are very informative. Each article is written by someone who is an expert on the particular faith, and usually the author also holds that particular belief and the position on peace that they are defending. Thus, each article represents the most peaceful way of interpreting the religion, however the authors are honest and also mention the non-peaceful activities taking place within their faith. If the authors do not hold to the beliefs they are describing, their tone is very respectful.
Each chapter of the book reads as an academic paper would, and each chapter is written by a member of the faith which the focus of the chapter is on. The book is rather informative considering it is not overly long or excessive in any way. I was surprised at how readable it is as well. Nothing too complicated or wordy.
