Quilon, the first Indian Christian Diocese, is erected by Pope John XXII; the French-born Jordanus is appointed the first Bishop.

The Diocese of Quilon is a Latin Church ecclesiastical jurisdiction or diocese of the Catholic Church based in the southern Indian city of Kollam. It is a suffragan in the ecclesiastical province of the metropolitan Archdiocese of Trivandrum. The Diocese of Quilon covers an area of 1,950 km² that contains a population of some 4.8 million. At least 4.8% of the people in the area are Catholic.

Christianity is India's third-most followed religion with about 28 million adherents, making up 2.3 percent of the population as of the 2011 census. Christianity is the largest religion in parts of Northeast India, specifically in Nagaland, Mizoram and Meghalaya. It is also a significant religion in Arunachal, where about 30 percent of the state is Christian.

Pope John XXII, born Jacques Duèze, was head of the Catholic Church from 7 August 1316 to his death, in December 1334. He was the second and longest-reigning Avignon Pope, elected by the Conclave of Cardinals, which was assembled in Lyon. Like his predecessor, Clement V, Pope John centralized power and income in the Papacy and lived a princely life in Avignon.
