1886 – 1968
Karl Barth (1886–1968) was a Swiss Reformed theologian widely regarded as the most significant Protestant theologian of the twentieth century. His magnum opus, the multivolume Church Dogmatics, represents a sweeping neo-orthodox reconstruction of Christian doctrine grounded in Christocentric revelation. He broke decisively with nineteenth-century liberal theology and became a leading voice against the German Christian movement during the Nazi era.
