Should physicians be required to disclose their religious beliefs to patients? How should we think about institutional conscience in the health care setting? How should health care providers handle situations in which a family refuses treatment based on religious objections?  These questions and more are tackled in a new book, “Law, Religion and Health in the United States,” published by Cambridge University Press. The book is co-edited by Elizabeth Sepper, associate professor of law at Washington University in St. Louis, along with I. Glenn Cohen of Harvard Law School and Holly Fernandez Lynch of the University of Pennsylvania.
