Barth’s seminary trained him in classically liberal Christianity. He entered the pulpit with a set of beliefs that were brittle, insufficiently biblical, and ultimately irrelevant to real people. In the Titanic sermon, you can see him trying to make his liberalism stretch to cover currrent catastrophes. It stretched enough to cover the Titanic, but just barely. This sermon was a real stinker, a real sinker, and it went under pretty fast. But Barth’s preaching career kept going until a few years later when the outbreak of World War I would be an even more titanic challenge to the weak Christianity of his seminary training. When that happened, Barth couldn’t stretch the thin commitments of liberalism to fit the real world.
