Evangelium Vitae §65

⁶⁵ For a correct moral judgment on euthanasia, in the first place a clear definition is required. Euthanasia in the strict sense is understood to be an action or omission which of itself and by intention causes death, with the purpose of eliminating all suffering. "Euthanasia's terms of reference, therefore, are to be found in the intention of the will and in the methods used". Euthanasia must be distinguished from the decision to forego so-called "aggressive medical treatment", in other words, medical procedures which no longer correspond to the real situation of the patient, either because they are by now disproportionate to any expected results or because they impose an excessive burden on the patient and his family. In such situations, when death is clearly imminent and inevitable, one can in conscience "refuse forms of treatment that would only secure a precarious and burdensome prolongation of life, so long as the normal care due to the sick person in similar cases is not interrupted". Certainly there is a moral obligation to care for oneself and to allow oneself to be cared for, but this duty must take account of concrete circumstances. It needs to be determined whether the means of treatment available are objectively proportionate to the prospects for improvement. To forego extraordinary or disproportionate means is not the equivalent of suicide or euthanasia; it rather expresses acceptance of the human condition in the face of death. In modern medicine, increased attention is being given to what are called "methods of palliative care", which seek to make suffering more bearable in the final stages of illness and to ensure that the patient is supported and accompanied in his or her ordeal. Among the questions which arise in this context is that of the licitness of using various types of painkillers and sedatives for relieving the patient's pain when this involves the risk of shortening life. While praise may be due to the person who voluntarily accepts suffering by forgoing treatment with pain-killers in order to remain fully lucid and, if a believer, to share consciously in the Lord's Passion, such "heroic" behaviour cannot be considered the duty of everyone. Pius XII affirmed that it is licit to relieve pain by narcotics, even when the result is decreased consciousness and a shortening of life, "if no other means exist, and if, in the given circumstances, this does not prevent the carrying out of other religious and moral duties". In such a case, death is not willed or sought, even though for reasonable motives one runs the risk of it: there is simply a desire to ease pain effectively by using the analgesics which medicine provides. All the same, "it is not right to deprive the dying person of consciousness without a serious reason": as they approach death people ought to be able to satisfy their moral and family duties, and above all they ought to be able to prepare in a fully conscious way for their definitive meeting with God. Taking into account these distinctions, in harmony with the Magisterium of my Predecessors and in communion with the Bishops of the Catholic Church, I confirm that euthanasia is a grave violation of the law of God, since it is the deliberate and morally unacceptable killing of a human person. This doctrine is based upon the natural law and upon the written word of God, is transmitted by the Church's Tradition and taught by the ordinary and universal Magisterium. Depending on the circumstances, this practice involves the malice proper to suicide or murder.
