From Aklan to the Archdiocese of Manila
Sin studied at the San Vicente Ferrer Seminary and was ordained in 1954. He served as a missionary priest, seminary rector and bishop before becoming Archbishop of Jaro in 1972 and Archbishop of Manila two years later.
As martial law restricted political institutions and media, the Catholic Church retained networks capable of organising relief, communication and public criticism. Sin used that institutional position to defend political detainees and encourage nonviolent democratic participation.
The EDSA appeal and a political religious legacy
On 22 February 1986, Sin appealed through Radio Veritas for people to bring food and support to the forces around Enrile and Ramos. Large civilian crowds then helped shield the camps and made a military assault politically and morally dangerous.
Sin remained a powerful public voice after 1986 and also supported the 2001 mobilisation that removed President Joseph Estrada. Admirers saw moral leadership; critics questioned the church’s political reach. Both views recognise that his career made religion a major actor in the country’s democratic transitions.
