Evangelism and social activism Maggay is known for her work as a social activist, advocating for evangelicalism to have an
integral mission, that brings together evangelism and social activism. In 1978, Maggay co-founded the Institute for Studies in Asian Church and Culture (ISACC) in response to the crisis posed by the
dictatorship of Ferdinand Marcos.
During the 1986 People Power Revolution Dr. Maggay's Institute for Studies in Asian Church and Culture (ISACC) and Dr.
Isabelo Magalit's congregation at the
Diliman Bible Church (DBC) were the main groups that came together to form Konsensiya ng Febrero Siete (KONFES) and participate in the EDSA
People Power Revolution of 1986. It was one of the early groups to man the barricades at Gate 2 of Camp Aguinaldo, which the Marcos military had identified as an entry point for storming the camp. In doing so, Maggay and Magalit joined the People Power Revolution earlier than other churches and organizations such as the
Philippine Council of Evangelical Churches. ==Works==
