“Faith in a written revelation is a real, unfeigned, and so far respectable faith, only where it is believed that all in the sacred writings is significant, true, holy, divine. Where, on the contrary, the distinction is made between the human and divine, the relatively true and the absolutely true, the historical and the permanent, - where it is not held that all without distinction is unconditionally true; there the verdict of unbelief, that the Bible is no divine book, is already introduced into the interpretation of the Bible, - … it's title to the character of a divine revelation is denied. Unity, unconditionality, freedom from exceptions, immediate certitude, is alone the character of divinity. A book that imposes on me the necessity of discrimination, the necessity of criticism, in order to separate the divine from the human, the permanent from the temporary, is no longer a divine, certain, infallible book, - it is degraded[.]”
Karl Barth was a Swiss Reformed theologian whom critics hold to be among the most important Christian thinkers of the 20th century.
Beginning with his experience as a pastor, he rejected his training in the predominant liberal theology typical of 19th-century Protestantism. Instead he embarked on a new theological path initially called dialectical theology, due to its stress on the paradoxical nature of divine truth (e.g., God's relationship to humanity embodies both grace and judgment). Other critics have referred to Barth as the father of neo-orthodoxy -- a term emphatically rejected by Barth himself. The most accurate description of his work might be "a theology of the Word." Barth's theological thought emphasized the sovereignty of God, particularly through his innovative doctrine of election.
Barth tries to recover the Doctrine of the Trinity in theology from its putative loss in liberalism. His argument follows from the idea that God is the object of God's own self-knowledge, and revelation in the Bible means the self-unveiling to humanity of the God who cannot be discovered by humanity simply through its own efforts.
