In Faithful to Secularism, David T. Buckley (DPDF ’10) argues that political institutions that encourage an active role for public religion are a key part in explaining this variation. He develops the concept of “benevolent secularism” to describe institutions that combine a basic division of religion and state with extensive room for participation of religious actors in public life. He traces the impact of benevolent secularism on religious and secular elites, both at critical junctures in state formation and as politics evolves over time. Buckley shows how religious and secular actors build credibility and shared norms over time, and explains how such coalitions can endure challenges from both religious revivals and periods of anticlericalism. Faithful to Secularism tests this institutional theory in Ireland, Senegal, and the Philippines, using a blend of archival, interview, and public opinion data. These case studies illustrate how even countries with an active religious majority can become and remain faithful to secularism.
