Richard B Hays’ The Moral Vision of the New Testament is the most beautiful book I’ve read for a long time. It’s sharper than ye olde two-edged sword:
One reason that the world finds the New Testament’s message of peacemaking and love of enemies incredible is that the church is so massively faithless. On the question of violence, the church is deeply comprimised and committed to nationalism, violence, and idolatry. (By comparison, our problems with sexual sin are trivial.) This indictment applies alike to liberation theologies that jsutify violence against oppressors and to establishment Christianity that continues to play chaplain to the military-industrial complex, citing just war theory and advocating the defense of a particular nation as though that were somehow a Christian value.
Only when the Church renounces the way of violence will people see what the Gospel means, because then they will see the way of Jesus reenacted in the church. Whenever God’s people give up the predictable ways of violence and self-defense, they are forced to formulate imaginative new responses in particular historical settings, responses as startling as going the second mile to carry the burden of a soldier who had compelled the defenseless follower of Jesus to carry it one mile first. The exact character of these imaginative responses can be worked out only in the life of particular Christian communities; however, their common denominator will be conformity to the example of Jesus, whose own imaginative performance of enemy-love led him to the cross. If we live in obedience to Jesus’ command to renounce violence, the church will become the sphere where the future of God’s righteousness intersects – and challenges – the present tense of human existence. The meaning of the New Testament’s teaching on violence will become evident only in communities of Jesus’ followers who embody the costly way of peace.
