‘To what shall I liken the basic principles of [liberal] theology? Is it not like a clock which is so cleverly constructed that the hands move from right to left instead of from left to right?’ – Karl Barth, ‘Letter from Barth to Thurneysen, 18 May 1924’, in Revolutionary Theology in the Making: Barth-Thurneysen Correspondence, 1914-1925, 183.
