Gandhi today is universally recognised as an international icon, but did his influence extend to the Vatican as well? The author unravels the answer by pursuing six research targets. The book opens with a historical inquiry into Gandhi's unsuccessful attempt to meet Pius XI, and then goes on to examine the writings and speeches of the Popes from Pius XI to Benedict XVI who alluded to Gandhi. Adopting a hermeneutical slant, it also engages in a comparative study of the thoughts and actions of Pope Francis and Gandhi, and highlights some remarkable similarities that call for an explanation. In the process, the book explores and assesses the popular claim that Gandhi was influenced by Christ, and the not so popular conjecture that Francis was influenced by Gandhi.
