The internationally growing Cursillo movement, or "short course in Christianity," founded in 1944 by Spanish Catholic lay practitioners, has become popular among American Catholics and Protestants alike. This lay-led weekend experience helps participants recommit to and live their faith. Emphasizing how American Christians have privileged the individual religious experience and downplayed denominational and theological differences in favor of a common identity as renewed people of faith, Kristy Nabhan-Warren focuses on cursillistas—those who have completed a Cursillo weekend—to show how their experiences are a touchstone for understanding these trends in post-1960s American Christianity. Drawing on extensive ethnographic fieldwork as well as historical research, Nabhan-Warren shows the importance of Latino Catholics in the spread of the Cursillo movement. Cursillistas' stories, she argues, guide us toward a new understanding of contemporary Christian identities, inside and outside U.S. borders, and of the importance of globalizing American religious boundaries.
