When the 750th birthday of Dante Aligheri (1265-1321) was celebrated in Italy in May, Pope Francis invited Catholics all over the world to take up and read one of the cornerstone works of Western and Christian civilization, The Divine Comedy, as an act of preparation for the extraordinary Holy Year of Mercy which launches Dec. 8.  Francis says Dante “is a prophet of hope, herald of the possibility of redemption, liberation and the profound transformation of every man and woman, of all humanity.”
