Though many scholars and commentators have predicted the death of religion, the world is more religious today than ever before. And yet, despite the persistence of religion, it remains a woefully understudied phenomenon. With Objective Religion, Baylor University Press and Baylor’s Institute for Studies of Religion have combined forces to gather select articles from the Interdisciplinary Journal of Research on Religion that not only highlight the journal’s wide-ranging and diverse scope, but also advance the field through a careful arrangement of topics with ongoing relevance, all treated with scientific objectivity and the respect warranted by matters of faith. This multivolume project seeks to advance our understanding of religion and spirituality in general as well as particular religious beliefs and practices. The volume thereby serves as a catalyst for future studies of religion from diverse disciplines and fields of inquiry including sociology, psychology, political science, demography, economics, philosophy, ethics, history, medicine, population health, epidemiology, and theology. The articles in this volume, Competition, Tension, and Perseverance, document the pervasiveness of religion and demonstrate the complex ways faith, spirituality, and religious matters are consequential for individuals as well as societies across the world. Together these essays demonstrate the resilience of religion.
