The glorious chapter of the expansion of the Catholic Church in the east can be said to have begun after the European 'discovery' of the sea route to India in 1498. This helped the coming of the European fathers to these lands, one of them being St. Francis Xavier, the great Apostle of the East and Patron of the Missions. Goa is privileged to have been the starting point of his Church work and the place where his sacred remains are preserved.
Goa was called the "Rome of the East" due to the central role it played in the evangelization of the east. One Goan priest, Father Joseph Vaz, who distinguished himself in the evangelization of Sri Lanka and is therefore acclaimed as the 'Apostle of Ceylon', was beatified by Pope John Paul II on Jan. 21, 1995. Another Goan priest, Father Agnelo de Souza, member of the Missionary Society of Pilar, is hopefully on the way to beatification. Pope Clement VII erected the See of Goa on Jan. 31, 1533. Its Jurisdiction extended from the Cape of Good Hope in South Africa, to China and Japan. On Feb. 4, 1557, Pope Paul IV detached Goa from the province of Lisbon and raised it to a metropolitan archdiocese, having as suffragans the dioceses of Cochin and Malacca (Malaysia). In the course of time, the Sees of Macau (near Hong Kong), Funay (Japan), Cranganore, Mylapore, Nanking and Peking in China, Mozambique in East Africa and Daman were created and made suffragans of Goa.
In 1572, Pope Gregory XIII acknowledged the archbishop of Goa as the primate of the East. By 1857, Goa had gained some more suffragans while, on the other hand, it had lost most of its overseas suffragans, to the exception of Macau and Mozambique.
On Jany 23, 1886, Pope Leo XIII made the archbishop of Goa patriarch of East Indies. In the same year, the archdiocese of Cranganore was suppressed and its title was annexed to the diocese of Daman.
