Over the decades, moral and political authority of the church in the Philippines is perceived to have waned with the passing of one its icons, Cardinal Jaime Sin.
Sin shaped the role of the church during the country's darkest hours after dictator Ferdinand Marcos imposed martial law starting in 1972 by championing the cause of civil advocacy, human rights and freedoms. Sin's action mirrored that of his strong backer, Pope John Paul II, who himself challenged communist rulers in Eastern Europe.
Three years after Aquino's father, Benigno Aquino Sr., a senator opposing Marcos, was gunned down on the Manila airport tarmac in 1983, Sin persuaded Aquino's widow, Corazon, to run for president.
When widespread election cheating by Marcos was exposed, Sin went on Catholic-run Radio Veritas in February 1986 to summon millions of people to support military defectors and the Aquino-led opposition. Marcos fled and Aquino was sworn in as president.
