Catholic health care is one of the key places where the church lives Catholic social teaching (CST). Yet the individualistic methodology of Catholic bioethics inherited from the manualist tradition has yet to incorporate this critical component of the Catholic moral tradition. Informed by the places where Catholic health care intersects with the diverse societal injustices embodied in the patients it encounters, this book brings the lens of CST to bear on Catholic health care, illuminating a new spectrum of ethical issues and practical recommendations from social determinants of health, immigration, diversity and disparities, behavioral health, gender-questioning patients, and environmental and global health issues.
