The Analogy of Grace: Karl Barth’s Moral Theology by Gerald McKenny, and: Christian Ethics as Witness: Barth’s Ethics for a World at Risk by David Haddorff (review)

Karl Barth’s theology remains a resource for Christian ethics. Let me suggest why. Instead of marginalizing or bracketing out consideration of divine agency, Barth presupposes God’s past, present, and future action; God’s inalienable subjectivity and indissoluble over-againstness in relationship (irreducible, for example, to ecclesial action); and God’s ongoing judgment of good and evil, and thus of moral thought and practice. These presuppositions determine the method, structure, content, and purpose of his theology and ethics. His concept of grace consists of God accomplishing the good in our place and on our behalf, a perspective more substantive than supplementary in nature. Finally, his eschatological view of human freedom involves resistance and responsibility—the freedom to resist evil (having been delivered from the determination of evil by grace) and the freedom to witness to God’s action in faith, love, and hope in the world. Barth’s work serves the field of Christian ethics well, burdened as we are by unprecedented global awareness with its challenges and uncertainties.

Two new books on Barth’s theology and ethics seek to increase our understanding of his work and engage contemporary Christian moral thought and practice. Gerald McKenny’s The Analogy of Grace is now the indispensable guide to Barth’s ethics. His exposition is comprehensive, critical, and contextual as it relates Barth’s dogmatics to current academic work in Christian ethics and moral philosophy. The tradeoff, however, is that it pays insufficient attention to the ecclesial, cultural, and political contexts for embodying Barth’s ethics. McKenny makes an important contribution to our understanding of Barth’s work. By closely reading primary texts and secondary literature, McKenny shows that many of Barth’s critics and friends continue to misunderstand him by resolving the unresolvable, airbrushing ambiguities and thus converting Barth’s “strange” ethics into a more conventional moral theory. McKenny argues that it is precisely the strangeness of Barth’s theology—with all its implications—that continues to challenge and contribute constructively to contemporary Christian ethics.

What is so strange and significant about Barth’s work? For McKenny, it is Barth’s claim that “God resolves on the good from eternity in the determination of humanity in Jesus Christ to commission and service as active witnesses of God’s glory; fulfills it in time in the incarnation, life, death, resurrection, and ascension of Jesus Christ, who performs this commission and service in place of all of humanity; and summons, empowers, and directs human beings in every time to correspond to this fulfillment in their conduct” (288). Thus, our action should be modeled on God’s action; it should be an analogy of grace. “The telos of God’s grace is realized,” McKenny concludes, “when human beings in their action become the image of God” (208). The Analogy of Grace traces the way Barth develops this ontological and analogical vision as McKenny differentiates Barth’s work from modern theories that presuppose that people are relatively capable of knowing and doing the good.

McKenny suggests that there is a possible deficiency in the way Barth’s account of divine agency determines the form and content of his theology and ethics. Barth’s consistent opposition to moral theories that emphasize observable signs of moral progress in either self or society results in the “liability” of the “extraordinarily qualified affirmation he gives to visible human goodness” (223). McKenny asks if Barth “does justice to the work of the Holy Spirit in our lives” and “can make sense of the participation of our action in God’s action or of the way in which the Holy Spirit accomplishes this participation” (223). In other words, Barth’s “extraordinarily qualified affirmation” might neglect the work of the Spirit in...
