The Diocese of Quilon is a Latin Church diocese of the Catholic Church based in the southern Indian city of Kollam. The diocese was created in 1329 but the Bishop did not take canonical possession and then Gregory XVI made Quilon as the new diocese suffragan of Verapoly on 1 September 1886. Then diocese was made as a suffragan in the ecclesiastical province of the metropolitan Archdiocese of Trivandrum. The Diocese of Quilon covers an area of 1,950 km2 (753 square miles) that contains a population of some 4.8 million. At least 4.8% of the people in the area are Catholic.
The history of the Roman Catholic Church in Quilon begins with the erection of a diocese on 9 August 1329. This diocese was later suppressed. The present day Diocese of Quilon was established as an apostolic vicariate on 15 March 1853 by bifurcating the Apostolic Vicariate of Verapoly. It was elevated to a diocese on 1 September 1886.
As of 18 April 2018, Paul Antony Mullassery is the bishop of the Diocese of Quilon.
According to tradition, St. Thomas the Apostle established seven churches along the southern part of west coast of India, and Quilon (pronounced Koy-lon) is the second in the list of the above seven churches. The official website of Kollam Diocese rejects the traditional claim that Thomas the Apostle founded churches in Kerala due to lack of historical proof, but accepts that he visited northwestern India near Taxila, was martyred there, and that his relics were later taken to Edessa in Turkey.
John of Monte Corvino, a member of the Societas Peregrinantium Pro Christo on his way to China, landed in Quilon in 1291 and ministered the Nestorian Christian community. The Venetian traveller Marco Polo who visited India in 1292 testified to the presence of a Christian community in Quilon.
Erection of the diocese its first bishop
Since the latter half of the 13th century, Quilon became the chief centre of Catholic missionary expeditions. Franciscan and Dominican Missionaries in the 13th and 14th centuries visited Quilon and their letters confirm the existence of a vibrant Nestorian Christian community in Quilon. The local adherents of Church of the East were later forcibly incorporated into the Catholic Church through the Synod of Diamper.
In 1329 Pope John XXII, from the Holy See then in Avignon (France), erected Quilon as the first Diocese in the whole of Indies as suffragan to the Archdiocese of Soltaniyeh in Persia through the decree "Romanus Pontifex" dated 9 August 1329 By a separate bull, "Venerabili Fratri Jordano", the same Pope, on 21 August 1329 appointed the French or Catalan Dominican friar Jordanus Catalani as the first Bishop of Quilon.
(Copies of the Orders and the related letters issued by Pope John XXII to Bishop Jordanus Catalani and to the diocese of Quilon are documented and preserved in the diocesan archives. Also reprinted in the Indian Church History Classics, Vol.I, The Nazranies, South Asia Research Assistance Services, Ed. Prof. George Menachery, Ollur, 1998.)
The ancient diocese of Quilon had extensive jurisdiction over modern nations of India, Pakistan, Afghanistan, Bangladesh, Burma and Sri Lanka.
Jordanus Catalani arrived in Surat in 1320. After his ministry in Gujarat he reached Quilon in 1323. He not only revived Christianity but also brought hundreds to the Christian fold. He might have come again to Quilon as the bishop in 1330 to build the church at Quilon, known as St. George of the Latins. George happened to be the patron saint of the Catalans, besides being popular among other Christian communities on the Malabar coast. His book "Mirabilia Descripta" is a rare work on plants, animals and the people of India and of other countries in Asia and this is an authoritative work on India dating 700 years back. This book is considered to be a landmark chronicle of its time written around 1327.
The first Latin Bishop of Quilon was received with great jubilation by the faithful of Quilon. And this Makes the St. George Church he build at Kollam a Cathedral, the first Cathedral church in India. He brought a message of good wishes from the Pope to the local rulers. As the first Latin bishop in India, he was also entrusted with the duty of spiritual nourishment of the Christian community in Calicut, Mangalore, Thane and Baruch (Gujarat). According to Portuguese sources, written more than two centuries later, he was martyred by Muslims in Bombay in 1336, as much as the four Franciscan friars that he had to bury, fifteen years before, in the very same place (one of them, Thomas of Tolentino, was beatified). In the year 1348 John De Marignoli, the Papal Legate to China on his way back to Rome sojourned here for 14 months. With the martyrdom of the first Latin Bishop, the See of Quilon remained vacant. There was a 'historic gap' with regard to ecclesiastical administration in India till the Portuguese landed here in 1498 AD.
It follows from the Friar Jordanus tradition that Catholicism – not just Christianity – is deep rooted in Quilon. It is now settled that Latin Catholicism was brought to Kerala in the early 14th century by this Catalan or Occitan speaking Dominican. It is now evident that while Bishop Jordanus introduced Latin Catholicism, the Portuguese popularized it. In the 1340s, an Italian friar called Marignolli called on Kollam and still found a Catholic church that he mentions as Saint George of the Latins, probably built by Jordanus (Saint George was popular among the Malabar Syrian Christians, but also happens to be the Patron Saint of Catalonia). The fact that Quilon is the founding seat of the Catholic Church in India is often found obscured in the midst of history.
Franciscan missionary activity
John De Marignolli (Giovanni de' Marignolli) of St. Lorenzo in Florence, joined the Franciscan order and was consecrated bishop in 1338 AD. He was chosen as legate to China by Pope Benedict XII (1334–1342). He preached in China and on his way back from China, he landed at Quilon and lived there for over a year, preaching in St. George's Church, which was founded by Jordanus.
In 1338 during the Pontificate of Pope Benedict XII (1334–1342) the great Khan of Peking in China sent a great delegation of ambassadors to the Pope at Avignon and were given a royal reception by the Pope. They requested the Pope to send a legate who would be wise, capable and virtuous to care for their souls. Responding to their request the Pope chose John De Marignolli as his legate to China and he accompanied the ambassadors of Great Khan on their homeward journey. Marignolli departed with a great number of friars and precious gifts for Khan, princes and sovereigns. They departed in March 1339 and after a long and perilous journey reached their destination, Khanbalique in 1342 and were received by the Great Khan, who was the last of the Mongol dynasty in China.
After three years of mission Marignolli decided to return to Europe. On his departure on 26 December 1345 he set out for Quilon where he arrived on 23 March 1346. The Christians of Quilon warmly welcomed him. He lived there for over a year, and preached in St. George's Church, founded by Jordanus.
He concentrated himself in the Latin Church of St. George founded by Bishop Jordanus. He preached in this Church and adorned the Church with paintings. He could not do much of missionary activity here since he became sick with dysentery during his stay at Quilon. When he recovered he visited Cape Comorin the extremity of Indian Peninsula where he erected a marble pillar mounted by a cross in full view of Ceylon. It seems that he was an ambitious man and was desirous that the good people of Quilon should never forget him and that was the intention of the erection of the marble pillar. The column, which was to endure till the world's end soon crumbled under the corroding influence of the elements and the inscriptions, were destroyed. Later a wrong tradition developed, attributing this column to St. Thomas. Marignolli set for Sumatra and Ceylon in July 1347. In September 1348 he came back to India. He left India in 1350 AD.
