Title: “Karl Barth on Nothingness: A Christological-Predestinarian Defiance of Theodicy” Abstract This article examines Karl Barth’s treatment of the theodicy problem in Church Dogmatics III/3, §50 (‘God and nothingness’). This part-volume sets forth Barth’s doctrine of providence, and in §50 he takes the theodicy problem head-on. By demonstrating how Barth develops his understanding of sin, evil, and death as “nothingness” (German: das Nichtige, a term to which he gives the definition and delimitation of ‘that which is not’) on the basis of his Christocentric doctrine of election, this article contends that this term, often misunderstood as a meontological notion, is in fact a Christological-predestinarian notion that engages deeply and yet critically with Reformation and post-Reformation Reformed theology. For Barth, the term “nothingness” is not meant to connote ontological privation, even though there is a limited sense in which nothingness can be described as privatio. Rather, central to the notion of “nothingness”—“that which is not”—is Barth’s insistence on God’s gracious election in Christ, part and parcel of which is God’s absolute non-willing and rejection of the negative element that assails God’s covenant-creature. This Christocentric ontology that Barth developed in 1936-1942 lies at the core of his discussion of nothingness, and, in line with the epistemological implications of this ontology, he makes a concerted effort to avoid metaphysical rationalisation or explanation of nothingness. For this reason, he not only defies the theodicy problem with a Christus Victor, “Mozartean” attitude, but also he rejects theodicy projects as altogether unable to avoid natural-theological speculation about God’s sovereignty and graciousness in abstract terms. Barth insists that true knowledge of nothingness is possible only in light of Christ’s eternal and a priori (‘zum Vornherein’) triumph over it, as manifested in the event of the birth, death, and resurrection of the Son of God. It is the history (Geschichte) of God’s covenantal faithfulness to the creature in Jesus Christ that God manifests Godself to be gracious and sovereign. In other words, humans are not in the place to vindicate God—hence Barth’s rejection of theodicy; only God can and does answer the theodicy problem. It remains open to question, of course, whether Barth is always true to his fundamental conviction that nothingness has absolutely nothing to do with God, and to his avowed rejection of rational explanations of nothingness. Whatever the case, Barth’s intention in treating sin, evil, and death as “nothingness” is to utter a metaphysical “I don’t know” about the dark mystery, and, more importantly, a Christological “I know” about God’s sovereign graciousness to the covenant-partner in Jesus Christ, thereby replacing theodicy with the category of witness.
