Bonhoeffer's theologically rooted opposition to National Socialism first made him a leader, along with Martin Niemueller and Karl Barth, in the Confessing Church (bekennende Kirche), and an advocate on behalf of the Jews. Indeed, his efforts to help a group of Jews escape to Switzerland were what first led to his arrest and imprisonment in the spring 1943. His leadership in the anti-Nazi Confessing Church and his participation in the Abwehr resistance circle (beginning in February 1938) make his works a unique source for understanding the interaction of religion, politics, and culture among those few Christians who actively opposed National Socialism, as is particularly evident in his drafts for a posthumously published Ethics.
His thought provides not only an example of intellectual preparation for the reconstruction of German society after the war but also a rare insight into the vanishing social and academic world that had preceded it. Bonhoeffer was also a spiritual writer, a musician and an author of fiction and poetry. The integrity of his Christian faith and life, and the international appeal of his writings, have led to a broad consensus that he is the one theologian of his time to lead future generations of Christians into the new millenium.
He was hanged in the concentration camp at Flossenbürg on April 9, 1945, one of four members of his immediate family to die at the hands of the Nazi regime for their participation in the small Protestant resistance movement. The letters he wrote during these final two years of his life were posthumously published by his student and friend, Eberhard Bethge, as Letters and Papers from Prison. His correspondence with his fiance, Maria von Wedermeyer, has been published as Love Letters from Cell 92.
(his twin sister was married to a U of Goettingen professor whose father was Jewish---I don't know if the sister's husband was Jewish or Christian or whatever in belief, but of course it was biology not theology that was important to the Nazis)
(Bethge was not just Bohoeffer's student and friend; he was married to one of Bonhoeffer's nieces)
