She wrote a large number of books, including "Theology for Skeptics: Reflections on God" (1968), "The Silent Cry: Mysticism and Resistance" (1997), and her autobiography "Against the Wind: Memoir of a Radical Christian" (1999). In "Beyond Mere Obedience: Reflections on a Christian Ethic for the Future" she coined the term "Christofascist" to describe fundamentalists. Perhaps her best-known work in English was "Suffering", which offers a critique of "Christian masochism" and "Christian sadism". Sölle's critique is against the assumption that God is all-powerful and the cause of suffering; humans thus suffer for some greater purpose. Instead, God suffers and is powerless alongside us. Humans are to struggle together against oppression, sexism, antisemitism, and other forms of authoritarianism.
