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. The great German theologian Karl Barth appeared to provide a remedy for this, with a theology that harkened back to Protestant Reformation. 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. Phillip D. R. Griffiths is currently the Head of Religious Studies at a large comprehensive school in West Wales, where he lives with his wife and two children. He holds four degrees, two with first class honors.
