Pope John Paul II's recent declarations about the moral necessity of feedings tubes for people in a condition such as Terri Schiavo conflicted with everything I had learned about directives concerning artificial life support in the Catholic faith.
I produce below an excerpt from the 2001 United States Conference of Catholic Bishops on "Ethical and Religious Directives for Catholic Health Care Services." My understanding is that the Pope's recent declarations on this subject are not binding for practicing Catholics. Clearly his words conflict with the Council of Bishops and Catholic Hospital Associations views about what can be the burdensome nature of life sustaining technology. How are Catholics reconciling these competing statements? Have you priests addressed these issues in Church?
"Christ's redemption and saving grace embrace the whole person, especially in his or her illness, suffering, and death.35 The Catholic health care ministry faces the reality of death with the confidence of faith. In the face of death—for many, a time when hope seems lost—the Church witnesses to her belief that God has created each person for eternal life.36 . . .
The truth that life is a precious gift from God has profound implications for the question of stewardship over human life. We are not the owners of our lives and, hence, do not have absolute power over life. We have a duty to preserve our life and to use it for the glory of God, but the duty to preserve life is not absolute, for we may reject life-prolonging procedures that are insufficiently beneficial or excessively burdensome. Suicide and euthanasia are never morally acceptable options.
The task of medicine is to care even when it cannot cure. Physicians and their patients must evaluate the use of the technology at their disposal. Reflection on the innate dignity of human life in all its dimensions and on the purpose of medical care is indispensable for formulating a true moral judgment about the use of technology to maintain life. The use of life-sustaining technology is judged in light of the Christian meaning of life, suffering, and death. Only in this way are two extremes avoided: on the one hand, an insistence on useless or burdensome technology even when a patient may legitimately wish to forgo it and, on the other hand, the withdrawal of technology with the intention of causing death.37
Some state Catholic conferences, individual bishops, and the USCCB Committee on Pro-Life Activities (formerly an NCCB committee) have addressed the moral issues concerning medically assisted hydration and nutrition. The bishops are guided by the Church's teaching forbidding euthanasia, which is "an action or an omission which of itself or by intention causes death, in order that all suffering may in this way be eliminated."38 These statements agree that hydration and nutrition are not morally obligatory either when they bring no comfort to a person who is imminently dying or when they cannot be assimilated by a person's body. The USCCB Committee on Pro-Life Activities' report, in addition, points out the necessary distinctions between questions already resolved by the magisterium and those requiring further reflection, as, for example, the morality of withdrawing medically assisted hydration and nutrition from a person who is in the condition that is recognized by physicians as the "persistent vegetative state" (PVS).39"
