What does the Bible say about war? Does Christianity necessitate pacifism? What is just war? These are questions Augustine asked after the fall of Rome in 410, and questions evangelicals ask today. In an era of guerrilla conflicts, weapons of mass destruction, and preemptive warfare the boundaries have become even more hazy: Is it alright to start a war if it might prevent other wars? While many wars have definite end dates, some are more subtle and ongoing: the war against drugs, class warfare, and of course, the ever-present conflict in the Middle East. Inevitably, Christians can be found at almost every level of these conflicts: some on the front lines, some working for humanitarian agencies, and others in diplomatic roles.
