Christian Jihad, written by Ergun and Emir Caner, gives a detailed overview and examination of Christian history from the early church through the middle ages up until the time of the Reformation, particularly elucidating the views of war by the major figures in each era, from passivity to aggression. In addition this work provides insight into the relationship of the Church and State through those time periods. It also provides an honest and unapologetic account of when Christendom pronounced Holy Wars against Islamic regimes and sought to make converts by force. I believe this book is most helpful in giving contemporary Christians a more in-depth understanding into the dynamics, thinking and details throughout Christian history regarding war and religious conflict. It gives insight in regards to these issues for contemporary Christians and the lessons that can be learned from history. Additionally, this book provides a very helpful appendix regarding “just war criteria” from thoughts of major thinkers throughout Christian history. This work is a must read for Christians and non-Christians alike.
