I don't think this is the same edition I read, and it may have been a slightly different title. But I found it in the library one day, and it was something like this (through I didn't read the entire thing). But what I read was fascinating. Barth was not a pacifist, but he despised how lightly many of Christ's words seemed to be taken by Christians. At the same time, when the Nazi's began their program, he joined up with the Austrian National Guard as an older man, insisting that he be given something to do to fend off tyranny. Yoder seems to have had great admiration for Barth.
