Euthanasia, physician-assisted suicide, and Christianity's positive relationship to the world

This essay addresses the problem of communication between Christianity and the secular world in an area where the latter tends to oppose the moral norms endorsed by the former. How, in the interest of missionary outreach (and with which understandings of what such outreach involves) can the language barriers be bridged? Whereas the Roman Catholic natural law tradition posits a neutral common ground of (traditional or hermeneutical) rationality between Christianity and the world, an Ebeling- and Barth-modified Lutheranism engages in an argument ad hominem by seizing upon an admitted deficiency within that world, and by recommending Christianity for mending that deficiency. Both positions differ from the Evangelical claim that since that which the world politically values is derived from Christianity, it must remain subject to Christianity's moral legislation. An entirely different approach to the communication- and outreach-problem is taken by Orthodox Christianity: The gulf which separates it from the world is acknowledged, and the possibility of trans-gulf-traffic is referred to God's grace. It is only this latter model, however, which preserves Christianity's theological terms (such as "Scripture", "law", and "holiness") from common-ground-securing, deficiency-mending, or authority-imposing secularizing, and thus from compromising that very theological context into which communicative outreach endeavors were to invite.
