The 4th bishop of Goan origin was D. Vicente do Rozario, a native of the village of Raia de Sálcete. He was a religious member of the congregation of St. Felippe Nery in Goa and therefore, according to the rules of his convent, he kept only his name and dropped the surname of Dias. His family now lived in the town of Margao, Goa. Having served for many years as a missionary on the island of Ceylon, a mission of his order, he was appointed superior of the island and after being erected as bishop by Pope Gregory XVI, he was elected and consecrated under the title of Bishop of Tamacene in 1837. Such was the apostolic selflessness of this worthy priest that throughout the entire period of his mission he did not send any subsidy to his family, still being certain of the near poverty to which they were reduced, until he died in Colombo in the year 1837 and upon his death he ordered the distribution of his spoils among the poor of Christianity on the island of Ceylon. .
The deputy for India, Mr. Joaquim Pedro Celestino Soares, captain of the Portuguese navy frigate, in a long speech he made in the courts in 1839 about Portuguese patronage, dedicates the following passage to a priest from Goa, who appears to be this one: In the Ceylon mission there was and still is a very respectable priest, a son of Goa, who has the sympathies of all that Christianity. The Holy See tried to introduce apostolic vicars there and the English, who even wanted to make our language be forgotten in those parts, helped this intended initiative of the Propaganda fide. The Italians went there but in vain because our Portuguese resisted them and expelled them.
