"If I have a system it is limited to a recognition of what Kierkegaard called the 'infinite qualitative distinction' and to my regarding this as possessing negative as well as positive significance: 'God is in heaven. And thou art on earth.' The relation between such a God and such a man, and the relation between such a man and such a God, is for me the theme of the Bible and the essence of philosophy. Philosophers name this KRISIS of human perception- the Prime Cause: the Bible holds at the same cross-roads-the figure of Jesus Christ. When I am faced by such a document as the Epistle of Paul to the Romans, I embark on its interpretation on the assumption that he is confronted with the same unmistakable and unmeasurable significance of that relation as I myself am confronted with, and that it is this situation which moulds his thought and its expression". Karl Barth, "The Epistle to the Romans" 1919 Preface (originally published in German)
