According to Eberhard Busch, Karl Barth's theology is "characterized by being...in constant movement and transformation." And a Christian's path is marked by self-correction in order to learn how to live out the same thing again and again in a better and more appropriate way. Likewise the church, like her God, is always on the move.

Abingdon Pillars of Theology is a series designed to help students grasp the basic and necessary facts, influence and significance of major theologians. Written by noted scholars, these books will outline the context, methodology, organising principles, primary contributors, and key writings of people who have shaped theology as we know it today.
