The Grammar of Pneumatology in Barth and Rahner: A Reconsideration

The trinitarian theologies of Barth and Rahner have tended to be read as failing to overcome a pneumatological deficiency that characterizes Western theology, despite the importance of their thought to proponents of the contemporary trinitarian 'revival'. This article argues, however, that in fact their conceptualizations of the doctrine of the Trinity depend upon essential pneumatological themes: Barth's understanding of the Spirit as the subjective reality of revelation's effect, and Rahner's proposals concerning the gift of the Spirit in terms of uncreated grace and quasi-formal causality. These insights have been largely overlooked or misconstrued, not least because both Barth and Rahner deploy their pneumatologies in the course of polemical debates with their nineteenth-century predecessors. A fresh reading of these theologians yields a pneumatology that I characterize as a grammar of the construction of graced subjectivity.
