Karl Barth

Barth, Karl (1886–1968), Swiss theologian, one of the most influential voices of 20th-century Protestantism. He taught in Germany 1921–35, was expelled by the Nazis, and spent the rest of his life in Basel. In his “crisis theology,” Barth stressed revelation and grace and reemphasized the principles of the Reformation, initiating a movement away from theological “liberalism.”
