Since the 1970s, the interrelated areas of medical genetics and biotechnology have developed dramatically and afforded increased control over the design of living organisms. From the very beginning, controversies over these techniques and their applications to plants, animals, and humans have raged in many disciplines-including science, philosophy, ethics, and religion. This book brings together the seminal essays of two leading Catholic moral theologians-Thomas Shannon and James Walter-in an effort to identify the key ethical and theological questions raised by the new genetic medicine. What is unique about this book is that it specifically and directly brings modern genetics and the Roman Catholic theological and ethical tradition into dialogue. While the authors argue that the Catholic tradition has much to offer in putting this current scientific revolution into perspective, they well understand the need to avoid merely repeating the tradition in favor of bringing the best of the tradition to bear on the precise questions posed by modern genetic technology.

During the past few decades, high-profile cases like that of Terry Schiavo have fueled the public debate over forgoing or withdrawing artificial nutrition and hydration from patients in a persistent vegetative state (PVS). These cases, whether involving adults or young children, have forced many to begin thinking in a measured and careful way about the moral legitimacy of allowing patients to die. Can families forgo or withdraw artificial hydration and nutrition from their loved ones when no hope of recovery seems possible? Many Catholics know that Catholic moral theology has formulated a well-developed and well-reasoned position on this and other end-of-life issues, one that distinguishes between "ordinary" and "extraordinary" treatment. But recent events have caused uncertainty and confusion and even acrimony among the faithful. In his 2004 allocution, Pope John Paul II proposed that artificial nutrition and hydration is a form of basic care, thus suggesting that the provision of such care to patients neurologically incapable of feeding themselves should be considered a moral obligation. The pope's address, which seemed to have offered a new development to decades of Catholic health care ethics, sparked a contentious debate among the faithful over how best to treat permanently unconscious patients within the tenets of Catholic morality. In this comprehensive and balanced volume, Ronald Hamel and James Walter present twenty-one essays and articles, contributed by physicians, clergy, theologians, and ethicists, to reflect the spectrum of perspectives on the issues that define the Catholic debate. Organized into six parts, each with its own introduction, the essays offer clinical information on PVS and feeding tubes; discussions on the Catholic moral tradition and how it might be changing; ecclesiastical and pastoral statements on forgoing or withdrawing nutrition and hydration; theological and ethical analyses on the issue; commentary on Pope John Paul II's 2004 allocution; and the theological commentary, court decisions, and public policy resulting from the Clarence Herbert and Claire Conroy legal cases. A valuable resource for students and scholars, this teachable volume invites theological dialogue and ethical discussion on one of the most contested issues in the church today.
