In our Age of Interaction, we need a historically based method for validating our ethics as standing on solid ground. Applying such a method to historical test times such as the Third Reich, the US Civil Rights Movement, and others, indicates that an ethic of incarnational discipleship, trinitarianly interpreted, passes the test. But this requires an interpretation of Jesus' Sermon on the Mount that corrects idealist interpretations, and points instead to realistic practices of deliverance. A new paradigm for interpreting the (...) Sermon on the Mount is demonstrated, with fourteen grace-based transforming initiatives of realistic deliverance from vicious cycles. A hermeneutic of analogical imagination is advocated for relating Jesus' practices in his context to effective practices of deliverance in our historical context. This points to realistic practices of just peacemaking that are effective in preventing wars and creating conditions that lead toward peace — and therefore are realistic for social ethics. (shrink)
