For decades, Engelhardt has alluded to the ethics that binds moral friends. While his 'Foundations of Bioethics' explored the sparse ethics binding moral strangers, this long-awaited volume addresses the morality at the foundations of Christian bioethics. The volume opens with an analysis of the marginalization of Christian bioethics in the 1970s and the irremedial shortcomings of secular ethics in general. Drawing on the Christianity of the first millennium, Engelhardt provides the ontological and epistemological foundations for a Christian bioethics that can remedy the onesidedness of a secular bioethics and supply the bases for a Christian bioethics. The volume then addresses issues from abortion, third-party-assisted reproduction, and cloning, to withholding and withdrawing treatment, physician-assisted suicide, and euthanasia. Practices such as free and informed consent are relocated within a traditional Christian morality. Attention is also given to the allocation of scarce resources in health care, and to the challenge of maintaining the Christian identity of physicians, nurses, patients, and health care institutions in a culture that is now post-Christian.
