As bishop he focused on rooting out Catharism, a heresy that was hanging on in his area. He helped Bernardo Gui and the Inquisition in this matter; the result was the Fournier Letters, records of the questioning that six centuries later became a best-seller. His efforts in fighting heresy brought him a promotion to Bishop of Mirepoix in 1326, and a cardinal a year later. While in Avignon, Pope John XXII—who was particularly concerned about magic—charged him with examining the works of William of Ockham, German mystic Meister Eckhart, Michael of Cesena, and others, looking for heresy.
Pope John died 4 December 1334; the Conclave was opened nine days later. The majority were ready to elect Cardinal Jean-Raymond de Comminges, but he had to promise not to return the papacy to Rome. Comminges would not make any prior commitments. The Conclave called his bluff by declaring their newest cardinal, Fournier, as a candidate. Because he was new, it was assumed he would not win an election. The Conclave should have planned more carefully: the vote was taken and Fournier won, surprising everyone who assumed they could vote for him but surely the majority would not, right?
Too late. The vote was legitimate, causing Fournier to exclaim "You have elected an ignoramus!" He took the name Benedict XII at his investiture on 8 January 1335. He worked hard to reform and standardize practices and expectations of the religious orders.
He died in his mid-50s, in 1342, but in his seven years as pope he accomplished a lot, and had a failure that led to one of the most defining events of the Middle Ages. We're going to take a look at the rest of his résumé tomorrow.
