Karl Barth's 'Dialectical Catholicity': Sic et Non

This essay attempts to achieve three things. First, it brings to the foreground an important but largely forgotten conversation partner of Karl Barth's theology: Roman Catholicism, and sketches Barth's critical and constructive engagement of it from his teaching at the University of Muenster (1925–1930) to his late booklet "Ad Limina Apostolorum". Second, it argues that Barth's engagement of Roman Catholicism functions as a crucial moment of his "dialectical catholicity", through which he discursively applies his critical, reflexive principle of "genuine Protestantism". Third, the essay puts forth a critique of Barth's transcendental account of "genuine Protestantism" by drawing on Martin Luther's concrete, ecclesially embodied pneumatology.
