We tell the story of a man who dedicated his life to preserving the Church, but instead led it into its greatest crisis: Joseph Ratzinger, Pope Benedict XVI. During his 30 years working within the Vatican he was the key figure in restoring fundamental Catholic doctrine after a brief period of modernization in the 1960s. Our interview partners, who have all worked within the clerical system, describe how Ratzinger’s policies contributed to the dramatic loss of moral authority that the Church suffers from today. We deal with Ratzinger’s past to understand his mind-set. We treat his key advisers - many of whom were involved in the cover-up of the global child sex abuse crisis and were implicated in corruption scandals. An epic story, with a tragic hero in the central role. Ratzinger, who believed that truth could exclusively be found in the teachings of the Church and that contemporary society was lost if it did not rediscover its Catholic values, was forced to acknowledge that his greatest enemies were inside the Church, even among his inner circle. By the time that he became aware of his errors, he found himself surrounded by chaos and enemies, his world crumbling around him.
