Since his surprise appointment in March of 2013, Pope Francis has emerged as the most talked-about and most revolutionary pope in living memory. He has become a subject of fascination, conversation, and headlines not only to the 1.2 billion Catholics in the world, but to virtually everyone. This biography of Pope Francis describes how this revolutionary thinker became who he is, and how he will use the power of his position to challenge and redirect one of the world's most formidable religions. Drawing on extensive interviews in Argentina and other countries, The Great Reformer traces the roots of his papacy in Francis's childhood in Buenos Aires, in his Jesuit training, and in the dramatic events during the Peron era and the military government in Argentina in the 1970s. It shows how these experiences have shaped his beliefs, and with his commitment to the discernment of God's will, enabled him to challenge and redirect the Church. Pope Francis was elected in the midst of one of the biggest crises in the Church in modern times. This is the story of a true radical who is transforming the Church by restoring what it has lost.
