Diocese of Boac, Catholic diocese in Marinduque, Philippines.
The Diocese of Boac is a Catholic Church jurisdiction on the island of Marinduque in the Philippines, covering the entire province. Its seat is the Cathedral of the Immaculate Conception, located in the town of Boac on the western side of the island.
The diocese was created in 1977 when it was separated from the Archdiocese of Manila, though Catholic missionary work on the island had started centuries before. Over time, the growing number of parishes across Marinduque made a dedicated local jurisdiction the natural next step.
The Cathedral of the Immaculate Conception in Boac is where the local community gathers for Sunday Mass, processions, and parish feasts. Devotion to Mary is visible everywhere on the island, from roadside shrines to banners hanging in market streets.
The cathedral in Boac town is the main starting point for a visit and is easy to reach on foot from the town center. Those interested in religious celebrations should plan their trip around Holy Week, when the island hosts its most attended events of the year.
The patroness of the diocese, the Mahal na Birhen ng Biglang-Awa, carries a title that translates from Filipino as "Our Lady of Sudden Grace". This local name shows how popular devotion on the island shaped the way Catholic faith took root here, distinct from titles used elsewhere in the country.
