Karl Barth (1886-1968), a Swiss theologian, was the founder of the neo-orthodox school of theology. He studied at various universities in Germany and became a liberal pastor for twelve years in Switzerland. After seeing first hand the inherent sinfulness of humanity during World War I he began studying Scripture and theologians like Calvin and Kierkegaard. Eventually, he abandoned liberal theology. In his multi-volume Church Dogmatics, he detailed his beliefs, which included the idea that God is transcendent and that humanity is separated from God due to sin – a condition that can only be resolved when the Holy Spirit reconciles us to God through Christ.
Impact: Neo-orthodox theology was, in many ways, universalist but was much more Christ-centered than the liberalism that reigned among scholars during the late nineteenth and early twentieth centuries.
