Portret van Johan Friedrich Röhr

Karl Barth was a Swiss Reformed theologian. Barth is best known for his commentary The Epistle to the Romans, his involvement in the Confessing Church, including his authorship of the Barmen Declaration, and especially his unfinished multi-volume theological summa the Church Dogmatics. Barth's influence expanded well beyond the academic realm to mainstream culture, leading him to be featured on the cover of Time on 20 April 1962.
