A comprehensive study brings the new interpretation of important but underestimated part of Karl Barth´ s Church Dogmatics (KD II/1, §§ 30-31), his doctrine of the perfections of God. The author demonstrates how and why the great dialectical theologian divided twelve traditional attributes of God into two series by six perfections and how successful he documented by biblical evidences both the tensions between the various perfections of God and the tension in the perfections themselves.
The last part of the study surveys the influence of Barths proposals and solutions on further treatments of this topic in German Protestant theology.
