point to a strong doctrinal and historical imperative against violence that exists within Christianity, particularly Jesus' Sermon on the Mount, which taught nonviolence and "love of enemies". For example, Weaver asserts that Jesus' pacifism was "preserved in the justifiable war doctrine which declares that all war is sin even when it is occasionally declared to be a necessary evil, and in the prohibition of fighting by monastics and clergy as well as in a persistent tradition of Christian pacifism". Many authors highlight the ironical contradiction between Christianity's claims to be centered on "love and peace" while, at the same time, harboring a "violent side". For example, Mark Juergensmeyer argues: "that despite its central tenets of love and peace, Christianity—like most traditions—has always had a violent side. The bloody history of the tradition has provided images as disturbing as those provided by Islam, and violent conflict is vividly portrayed in the Bible. This history and these biblical images have provided the raw material for theologically justifying the violence of contemporary Christian groups. For example, attacks on abortion clinics have been viewed not only as assaults on a practice that Christians regard as immoral, but also as skirmishes in a grand confrontation between forces of evil and good that has social and political implications.", sometimes referred to as spiritual warfare. The statement attributed to Jesus "I come not to bring peace, but to bring a sword" has been interpreted by some as a call to arms to Christians. Maurice Bloch also argues that the Christian faith fosters violence because the Christian faith is a religion, and religions are violent by their very nature; moreover, he argues that religion and politics are two sides of the same coin—power. Others have argued that religion and the exercise of force are deeply intertwined, but they have also stated that religion may pacify, as well as channel and heighten violent impulses In response to the view that Christianity and violence are intertwined, Miroslav Volf and J. Denny Weaver reject charges that Christianity is a violent religion, arguing that certain aspects of Christianity might be misused to support violence but that a genuine interpretation of its core elements would not sanction human violence but would instead resist it. Among the examples that are commonly used to argue that Christianity is a violent religion, J. Denny Weaver lists "(the) Crusades, the multiple blessings of wars, warrior popes, support
