Stanley Hauerwas

It is often observed that the first casualty of war is truth, but how do you tell the truth without betraying the sacrifice of those who accepted the terms of battle? War is a sacrificial system that creates its own justification. Hedges is right that war creates its own culture, but that it does so indicates the moral power of war. No doubt war creates a comradeship seldom found in other forms of life, but it does so because war subjects lives to sacrifices otherwise unavailable… The Christian alternative to war is worship. I am well known for the claim that the first task of the church is not to make the world more just, but to make the world the world. That claim is but a correlate of the assertion that the church does not have a social ethic. Rather the church is a social ethic.
