The Enlightenment caused a paradigm shift in the worldview of most people living in the Western world. Those Christian doctrines associated with the Protestant Reformation were believed to be no longer tenable.

From Calvin to Barth examines just how successful Barth was in returning to the old ways; to ascertain whether he did espouse the thinking of men like John Calvin or whether he simply provided a theological system that was just another face of post-Enlightenment liberal thinking.
