This second volume tells the story of the great heresies that seemed to carry all before them, yet always failed to gain their final goal of capturing the Papacy; of St. Patrick's mission to Ireland; of how the Popes became judges of kings and the First Crusade swept on to victory against all odds; of how the Church bridged the abyss of the Dark Ages and laid the foundations of a new Christian order. All Christian countries are covered, with the history of the Popes as the connecting thread.
