Born to Christopher Vaz and Maria de Miranda, Christian parents of the Konkani Brahmin caste; the third of six children. Attended primary and secondary school in Sancoale, where he learned Portugese, and Benaulim, where he learned Latin. He studied humanities at the Jesuit Goa University, philosophy and theology at Saint Thomas Aquinas Academy.
Ordained in 1676. Preacher and confessor. Opened a Latin school in Sancoale for perspective seminarians. Always devoted to Our Lady, in 1677 he consecrated himself as a “slave of Mary,” sealing it with a document known as his “Letter of Enslavement”.
About this time Joseph learned of the condition of Catholics in Ceylon; persecuted by the Dutch, they had had no priests for 50 years. He sought permission to work in Ceylon, but was asked to go to the mission in Kanara. He accepted, but his thoughts and heart were in Ceylon. Vicar of Vara in Kanara, preaching, hearing confessions, visiting the sick, helping the poor, ransoming Christian slaves, working to settle jurisictional disputes that interfered with the sacraments.
Meanwhile, a small congregation of priests had formed in Goa with the Church of the Holy Cross of Miracles as their residence. Joseph joined and was elected superior. He gave a definitive canonical status to this Oratory, introduced religious exercises and charitable activities, and trained its members for the mission. In 1686 he gave up his position, and set out for Ceylon. Disguised as an itinerant worker, he reached the port of Tuticorin on Easter 1687, and then the Dutch stronghold of Jaffna in the north of the Ceylon.
He suffered from acute dysentery, contracted from the terrible travelling conditions, and upon recovery he began his mission by contacting Catholics and hiding from the Dutch. He was taken in by a courageous Catholic, and ministered to his secret flock by night. One step ahead of the authorities, in 1689 he went to the Catholic village of Sillalai and began ministering to folks in surrounding villages.
In 1690 Joseph moved on to Puttalam in the Kingdom of Kandy, where 1,000 Catholics had not seen a priest for half a century. He decided to make Kandy the centre of his apostolate, and in 1692 he left for there, hoping to obtain royal permission to travel freely. Instead, he was preceded by Calvinist accusations of being a Portugese spy, and was imprisoned with two other Catholics. There he learned Sinhala, the local language, and since the prison guards left the prisoners alone as long as they didn’t try to escape, he built a hut-church and later a proper church dedicated to Our Lady, and began converting other prisoners.
In 1696 the Kingdom of Kandy was suffering a serious drought, and the king asked the Buddhist monks to pray to their gods for rain; there was no ran. He then turned to Joseph who erected an altar and cross in the middle of the square and prayed; abundant rain began to fall, while Joseph and his altar stayed dry. The king granted Joseph license to preach throughout the kingdom.
Making the most of his new-found freedom, he made a mission visit to the Dutch zone and visited Catholics in Colombo. Three missionaries from the Oratory of Goa arrived in 1697 to help him with the news that Don Pedro Pacheco, Bishop of Cochin, had appointed him Vicar General in Ceylon. He was organizing the basic mission structure when smallpox broke out in Kandy. His work with the sick convinced the king to allow Father Joseph every possible freedom in his labours.
Joseph carried his mission to the main centres of the island. He returned to Kandy in 1699 with Father Joseph de Carvalho who had been expelled at the instigation of Buddhist monks. He completed the construction of his new church, and went into service for the king, translating Portuguese books into Sinhala. From this vantage point, he intensified his ministry, and converted some Sinhalese notables, which gave rise to slanders against him and persecution of converts.
New missionaries arrived in 1705, which enabled him to organize the mission into eight districts, each led by a priest. He worked on the creation of a Catholic literature comparable to that of the Buddhists, and to affirm the rights of Catholics with the Dutch Protestant Government.
King Vimaldharna Surya II, Father Joseph’s mentor, died in 1707, but Narendrasimha, his successor, was an even greater supporter. New missionaries arrived in 1708, and in 1710, despite health problems, Joseph took another apostolic trip. On his return, he fell ill from his carriage, and reached Kandy in serious condition. Though he recovered from a series of infections and fevers over the next year, age, work, and disease had finally worn him out. He undertook nine days of spiritual exercises prescribed by the Rule, but before the seventh day, he was called home to God.
