A third, but less popular, option than either liberalism or fundamentalism was the neo-orthodox movement, which generally affirmed a higher view of Scripture than liberalism but did not tie the main doctrines of the Christian faith to precise theories of Biblical inspiration. If anything, thinkers in this camp denounced such quibbling between liberals and conservatives as a dangerous distraction from the duties of Christian discipleship. This branch of thought arose in the early 20th century in the context of the rise of the Third Reich in Germany and the accompanying political and ecclesiastical destabilization of Europe in the years before and during World War II. Neo-orthodoxy's highly contextual, dialectical modes of argument and reasoning often rendered its main premises incomprehensible to American thinkers and clergy, and it was frequently either dismissed out of hand as unrealistic or cast into the reigning left- or right-wing molds of theologizing. Karl Barth, a Swiss Reformed pastor and professor, brought this movement into being by drawing upon earlier criticisms of established (largely modernist) Protestant thought made by the likes of Søren Kierkegaard and Franz Overbeck; Dietrich Bonhoeffer, murdered by the Nazis for allegedly taking part in an attempt to overthrow the Hitler regime, adhered to this school of thought; his classic "The Cost of Discipleship" is likely the best-known and accessible statement of the neo-orthodox position.
