From Miroslav Volf…
One could object that it is not worthy of God to wield the sword. Is God not love, long-suffering and all-powerful love? A counter-question could go something like this: Is it not a bit too arrogant to presume that our contemporary sensibilities about what is compatible with God’s love are so much healthier than those of the people of God throughout the whole history of Judaism and Christianity?
…My thesis that the practice of nonviolence requires a belief in divine vengeance will be unpopular with many Christians, especially theologians in the West. To the person who is inclined to dismiss it, I suggest imagining that you are delivering a lecture in a war zone (which is where a paper that underlies this chapter was originally delivered). Among your listeners are people whose cities and villages have been first plundered, then burned and leveled to the ground, whose daughters and sisters have been raped, whose fathers and brothers have had their throats slit. The topic of the lecture: a Christian attitude toward violence. The thesis: we should not retaliate since God is perfect noncoercive love. Soon you would discover that it takes the quiet of a suburban home for the birth of the thesis that human nonviolence corresponds to God’s refusal to judge. In a scorched land, soaked in the blood of the innocent, it will invariably die. And as one watches it die, one will do well to reflect about many other pleasant captivities of the liberal mind.
