Old Testament violence is an interesting case in point. God clearly ordered the Hebrews to annihilate the Canaanites and surrounding peoples. Such violence is therefore an expression of God's will, for good or ill. Regardless, all the historic violence committed by the Hebrews and recorded in the Old Testament is just that—history. It happened; God commanded it. But it revolved around a specific time and place and was directed against a specific people. At no time did such violence go on to become standardized or codified into Jewish law. In short, biblical accounts of violence are descriptive, not prescriptive.
This is where Islamic violence is unique. Though similar to the violence of the Old Testament—commanded by God and manifested in history—certain aspects of Islamic violence and intolerance have become standardized in Islamic law and apply at all times. Thus, while the violence found in the Qur'an has a historical context, its ultimate significance is theological.
In fact, far from suggesting anything intrinsic to Christianity, the Crusades ironically better help explain Islam. For what the Crusades demonstrated once and for all is that irrespective of religious teachings—indeed, in the case of these so-called Christian Crusades, despite them—man is often predisposed to violence. But this begs the question: If this is how Christians behaved—who are commanded to love, bless, and do good to their enemies who hate, curse, and persecute them—how much more can be expected of Muslims who, while sharing the same violent tendencies, are further commanded by the Deity to attack, kill, and plunder nonbelievers?
