Swiss theologian Karl Barth (1886–1968) rocked the world of theology when he published his commentary on Romans in 1919. His focus on God as truly God and his return to Scripture “destroyed the older liberalism,” in one scholar’s words.

How much did Barth influence Bonhoeffer, who was twenty years younger?
Bonhoeffer studied theology at the great liberal faculties of Tübingen and Berlin. At the University of Berlin, he was especially stimulated by his study of Martin Luther. But the greatest theological influence on Bonhoeffer came from the writings of a Swiss theologian who was then teaching in Germany—Karl Barth.
Bonhoeffer never studied with Barth, but he devoured his writings. Barth led the new “dialectical theology” movement that was rediscovering the great themes of the Reformation and the “strange new world” within the Bible.
Like Barth, Bonhoeffer rejected the nineteenth century’s liberal theology, with its focus on human religion.

Bonhoeffer finally met Barth in the summer of 1931. “I was even more impressed by his discussion than by his writings and lectures,” Bonhoeffer said. The two remained friends, and they became allies, especially in the struggle against the “German Christian” theology that tried to amalgamate ...
