Notably, from 1968 to 1972 she organized the Politisches Nachtgebet [de] (political night-prayers) in the Antoniterkirche (Cologne).

[20] 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).

[6] In Beyond Mere Obedience: Reflections on a Christian Ethic for the Future she coined the term Christofascist to describe fundamentalists.

[2] In 1969, she married[23] the former Benedictine priest Fulbert Steffensky [de], with whom she had her fourth child[2] and with whom she organized the Politisches Nachtgebet.

Sölle was a kind of prophet of Christianity, who abolished the separation of theological science and practice of life, while for others[who?]

she was a heretic,[citation needed] whose theories couldn't be reconciled with the traditional understanding of God, and her ideas were therefore rejected as a theological cynicism.
