Karl Barth came to believe that the Christian culture during and after the 1st World War had accomodated itself too easily to the prevailing culture instead of providing a dynamic critique, so he reasserted doctrines of God's sovereignty and human sin. When Hitler rose to power, Swiss-born Barth joined the Confessional Church in opposing the Third Reich's violence. He was forced to give up his professorship, and devoted the rest of his life to writing his 13-volume opus on Church Dogmatics. Pius XII regarded him as the most important theologian since Thomas Aquinas. (Maria Netter)
