There are numerous challenges posed to Roman Catholic health care institutions by recent developments in health care delivery. Some are practical, involving the acceptable limits of accommodation to and collaboration with secular networks of health care delivery. Others, quite often implicated in the first set, are explicitly theological. What does it mean to be a distinctively Roman Catholic health care institution? What are the nature and the scope of Roman Catholic institutional identity? More broadly, what is the moral relevance of (...) themes in Roman Catholic social teaching to the provision of health care? This issue of Christian Bioethics addresses these questions with a spirited exchange among its authors. They offer noticeably different perspectives on the general cogency of Roman Catholic social teaching and different strategic recommendations for Roman Catholic institutions to maintain, or recover, their distinctive presence in health care delivery.
