George Hunsinger has this interesting quote: "Barth believed that the Bible confronts us with viewpoints that cannot be derived from elsewhere. . . . Another such writer was Walter Benjamin, whose distinction between 'Messianic time' and 'homogenous, empty time' also had affinities with what we find in Barth."
See Hunsinger, "Gerrit Neven on Karl Barth: A Brief Reflection".
