Abstract:
Orthodox Christian ethics is grounded in the sacredness of life principle. Yet, it can accept a quality of life approach where "quality" refers not to capacities or states, but to the relationship between the patient's condition and the quest for transcendent life goals (Walter and Shannon, 1990). The true quality of human life derives from the vocation to stewardship, which enjoins an attitude of humble acceptance toward beneficial or "redemptive" suffering. The proper response to suffering in terminal cases is not active euthanasia or physician-assisted suicide but appropriate pain management and personal care. In cases of PVS or deep coma, only the determination of higher brain death can warrant the withholding or withdrawing of food and hydration. Yet, artificial maintenance of biological existence is also immoral. Death is to be accepted and embraced as a transition to eternal life.
