The consecrated Bishop was D. Matheus de Castro, a native of the village of Divar, who sailed to Rome after being ordained as a priest; He studied at one of the colleges in that city and returned to Goa with a doctorate in theology and prior of the collegiate church of Luz. Returning to Rome, he received the prelatial vestments and in 1652 he was once again in India as bishop of Chrysopolis and apostolic vicar of the kingdoms of Idalsha, Pegu and Golconda in the East Indies and in the empire of Prester John, inquisitor and missionary of all these missions.
António João de Frias gives the following detailed account of the services of this prelate in his Aureola dos Índios, printed in Portugal in 1702. The first bishop was Doctor D* Matheus de Castro, bishop of Crisopolis, who went to India in the year 1655, a native of the island of Divar vicar apostolic of the kingdoms of Idaixa, Pegu, and Golconda in the East Indies, and in the empire of Prester John. He built 3 main churches in Mourama in Bicholim, Banda, and Vingurla in addition to many houses and residences in the courts of all the Moorish kings and gentiles where he landed.
It made it easier for the missionaries to preach the evangelical law in the lands with freedom, and their memories are preserved to this day. The Christians owe to this bishop the trade they have in the lands of the gentiles and the Moors, and the reverence and respect with which any priest is venerated in them. After carrying out a long mission in India, and propagating the law of Christ among the Gentiles, preaching the true faith, he went to Rome, where he was received by the supreme pontiff with great honors; and in it the congregation of Propaganda, live with joy, for having blessed a broad mission, and having borne fruit in the lands of the enemies of the faith: obtaining for the Christians, and missionaries, many concessions and freedoms from the infidel kings; building churches and housing for the mission workers. This bishop went to Rome four times; from the 1st, being a cleric, he graduated as a doctor in theology and prior of the collegiate church of Luz in this city of Goa. He was consecrated bishop, and returning there a third time, he attended the curia for many years, and died at the age of 119 in 1679, with great feeling. not only of the natives, whom he honored, opening the way for them to rise to such great dignities, but also of strangers, with whom he always lived in reputation and credit.
This bishop consecrated D. Raphael de Figueredo bishop of Adrometo in Cochin.
The three churches he built, according to what Fr Leonardo Paes says in his Promptuario das Definiçãos indicas (page 127 had the invocations of St. Salvador, St. Philippe Nery and Our Lady of the Conception)
When he became bishop, he brought from Rome a portrait of himself in prelatic robes, which still exists in Divar, in large print on the glass, with his name and title underneath; a painting which is preserved in honour of the son of the Island of Divar.
