Mar John III A.D 1129
The Saxon Chronicle relates that in 883 King Alfred the Great of England sent to India alms for St. Thomas and St. Bartholomew. Le quien, in his Orient "Christ", says that about the year 1129 the Catholicos of Bagdad sent to Malabar a Nestorian bishop, Mar John III. The Venetian traveler, Marco Polo, about 1295 speaks of Nestorian Christians in Malabar and narrates the tradition of the death in India of St. Thomas the Apostle. He says: - "The Christians who have the administration of the church possess forests of trees that bear the Indian nuts and from them they draw the means of their livelihood. As tax they pay monthly to one of the Royal brothers a groat for each tree."
First Latin missionary A.D 1291
The first Latin missionary who is known to have visited India was John of Monte Corvino, afterwards Archbishop of Cambalec in Cathay. Sent out by Pope Nicholas IV as a missionary to China, he on his way halted in India about the year 1291. In a letter which he wrote from Pekin in 1305 he says:- "I remained in the country of India, where stands the church of St. Thomas the Apostle, for thirteen months and in that reign baptised in different places about one hundred persons." In a letter dated 1306 he speaks of Malabar and says:- "There are a very few Christians and Jews and they are of little weight. The people persecute much the Christians and all who bear the Christian name. The next Latin missionary was a Dominican Friar named Jordanus, a Frenchman from near Toulouse. Perhaps as early as 1302 with other Dominican and Franciscan Friars he found his way to the Bombay coast where the Mahomedans put his companions to death. After various adventures Friar Jordan returned to Europe and wrote a small book called Mirabilia in which he briefly mentions the wonderful things he saw in the East. The only mention of Christians is as follows:- "In this India there is a scattered people, one here, another there, who call themselves Christians but are not so, nor have they baptism nor do they know anything about the faith. They believe St. Thomas the Great to be Christ! There, in the India I speak of, I baptised and brought into the faith about three hundred souls." In 1328 Pope John XXII at Avignon consecrated Friar Jordan as bishop of Quilon and sent him in 1330 with a Latin letter addressed to the chief of the Nazarene Christians at Quilon. The letter asked the goodwill of the Nazarene chief towards Bishop Jordan and his missionaries and ends by inviting these Christians to abjure their schism and to enter the unity of the Catholic Church. Bishop Jordan set out for India with this letter but it is not known if he reached his destination or if he had any successors in the See of Quilon. Another traveller, Friar Odoric, collected the bones of the martyred companions of Friar Jordan and in 1321 passed down this coast and touched at Quilon, where there were Christians, and at Mailapur, where were fifteen houses of Nestorian Christians.
