When we as LARR associate editors learned of the proposal of Jeffrey Rubin, David Smilde, and Benjamin Junge for this special issue, we were eager to be involved. Representing the journal, we had the great pleasure to attend meetings in Boston in 2011 and 2012 of this important new research initiative, initially titled “Religion, Social Movements, and Progressive Reform in Latin America,” where we heard many stimulating papers from a diverse range of scholars working in Latin America and the United States. At each meeting the group of presenters was never the same, which made for much exciting cross-fertilization of thinking in efforts to work through these themes, with stimulating and lively discussions moving from conference venues to restaurants and spilling out later onto the sidewalks of Boston. As our gracious host and the main convener of the meetings, Jeff Rubin skillfully wove together disparate views and approaches, moving toward the common threads that you see highlighted in this volume: zones of crisis, the day-to-day experience of religion, and citizenship. Each of the papers configures these themes in a unique way, demonstrating the undeniable centrality of religion as an inspiration and shaper of subjectivities, personal and public action, and engagement with politics in diverse settings across the Americas.
