We Christians are ashamed of many of our ancestors who did not act in the spirit of Christ. No doubt there are traces of this plague in our own souls. But true Christianity–which is radically different from Western culture, and may not be found in many Christian churches–renounces  the advance of religion by means of violence. “My kingdom is not of this world,” Jesus said. “If my kingdom were of this world, my servants would have been fighting” (John 18:36). The way of the cross is the way of suffering. Christians are called to die, not kill, in order to show how they are loved by Christ.
