At the National Shrine of Our Mother of Perpetual Help, representatives of displaced tribal people from the southern Philippines spoke to churchgoers during a Mass.

"It is the mission of the church to amplify the voice of the oppressed," said Redemptorist priest Teodulo Holgado. "It is our duty to provide spaces for them to speak and be heard."

The priest said tribal people in the Philippines are the "most marginalized sector ... because people do not understand their plight," adding that people have largely remained silent regarding attacks on tribal communities.

Bishop Antonio Ablon of the Philippine Independent Church, who has been tagged as a communist because of his work with tribal communities, said there is no reason to back off or be cowed.

"We are not committing a crime by serving the tribal people," said the prelate. He accused the Philippine military of attacking the church "because of our ministry for tribal people."

Rommel Linatoc of the National Council of Churches in the Philippines said, "being silent and complacent about the plight of tribal people is no longer an option."

Human rights group Karapatan reported earlier that at least five tribal people and peasant leaders have been arrested since the start of October due to their alleged links to communist rebels.

Meanwhile, tribal leaders have been actively opposing mining and logging concessions in ancestral lands.

In 1978 the Catholic Bishops' Conference of the Philippines declared every second Sunday of October as Tribal Filipino Sunday.

In the 1990s, following the lead of the United Nations, which formally described First Nations groups as Indigenous Peoples, local church leaders renamed the celebration as Indigenous Peoples Sunday.
