. . . Thus an act of omission [in this case, withdrawing routine feeding tubes] which, of itself or by intention, causes death in order to eliminate suffering constitutes a murder gravely contrary to the dignity of the human person and to the respect due to the living God, his Creator. The error of judgment into which one can fall in good faith does not change the nature of this murderous act, which must always be forbidden and excluded.
The Catechism is available online.
Pope John Paul II's encyclical Evangelium Vitae (The Gospel of Life) is also highly relevant. Euthanasia is condemned by the Second Vatican Council:
Whatever is opposed to life itself, such as any type of murder, genocide, abortion, euthanasia, or wilful self-destruction, whatever violates the integrity of the human person, such as mutilation, torments inflicted on body or mind, attempts to coerce the will itself; whatever insults human dignity, such as subhuman living conditions, arbitrary imprisonment, deportation, slavery, prostitution, the selling of women and children; as well as disgraceful working conditions, where people are treated as mere instruments of gain rather than as free and responsible persons; all these things and others like them are infamies indeed. They poison human society, and they do more harm to those who practise them than to those who suffer from the injury. Moreover, they are a supreme dishonour to the Creator.The pope in the above encyclical condemns euthanasia repeatedly (emphases added throughout):
(Pastoral Constitution on the Church in the Modern World [Gaudium et Spes], 27; emphasis mine)
"On a more general level, there exists in contemporary culture a certain Promethean attitude which leads people to think that they can control life and death by taking the decisions about them into their own hands. What really happens in this case is that the individual is overcome and crushed by a death deprived of any prospect of meaning or hope. We see a tragic expression of all this in the spread of euthanasia—disguised and surreptitious, or practised openly and even legally. As well as for reasons of a misguided pity at the sight of the patient's suffering, euthanasia is sometimes justified by the utilitarian motive of avoiding costs which bring no return and which weigh heavily on society. Thus it is proposed to eliminate malformed babies, the severely handicapped, the disabled, the elderly, especially when they are not self-sufficient, and the terminally ill. Nor can we remain silent in the face of other more furtive, but no less serious and real, forms of euthanasia. These could occur for example when, in order to increase the availability of organs for transplants, organs are removed without respecting objective and adequate criteria which verify the death of the donor."
"Aside from intentions, which can be varied and perhaps can seem convincing at times, especially if presented in the name of solidarity, we are in fact faced by an objective "conspiracy against life", involving even international Institutions, engaged in encouraging and carrying out actual campaigns to make contraception, sterilization and abortion widely available. Nor can it be denied that the mass media are often implicated in this conspiracy, by lending credit to that culture which presents recourse to contraception, sterilization, abortion and even euthanasia as a mark of progress and a victory of freedom, while depicting as enemies of freedom and progress those positions which are unreservedly pro-life."
"To claim the right to abortion, infanticide and euthanasia, and to recognize that right in law, means to attribute to human freedom a perverse and evil significance: that of an absolute power over others and against others. This is the death of true freedom: "Truly, truly, I say to you, every one who commits sin is a slave to sin" (Jn 8:34)."
"64. At the other end of life's spectrum, men and women find themselves facing the mystery of death. Today, as a result of advances in medicine and in a cultural context frequently closed to the transcendent, the experience of dying is marked by new features. When the prevailing tendency is to value life only to the extent that it brings pleasure and well-being, suffering seems like an unbearable setback, something from which one must be freed at all costs. Death is considered "senseless" if it suddenly interrupts a life still open to a future of new and interesting experiences. But it becomes a "rightful liberation" once life is held to be no longer meaningful because it is filled with pain and inexorably doomed to even greater suffering.
Furthermore, when he denies or neglects his fundamental relationship to God, man thinks he is his own rule and measure, with the right to demand that society should guarantee him the ways and means of deciding what to do with his life in full and complete autonomy. It is especially people in the developed countries who act in this way: they feel encouraged to do so also by the constant progress of medicine and its ever more advanced techniques. By using highly sophisticated systems and equipment, science and medical practice today are able not only to attend to cases formerly considered untreatable and to reduce or eliminate pain, but also to sustain and prolong life even in situations of extreme frailty, to resuscitate artificially patients whose basic biological functions have undergone sudden collapse, and to use special procedures to make organs available for transplanting.
In this context the temptation grows to have recourse to euthanasia, that is, to take control of death and bring it about before its time, "gently" ending one's own life or the life of others. In reality, what might seem logical and humane, when looked at more closely is seen to be senseless and inhumane. Here we are faced with one of the more alarming symptoms of the "culture of death", which is advancing above all in prosperous societies, marked by an attitude of excessive preoccupation with efficiency and which sees the growing number of elderly and disabled people as intolerable and too burdensome. These people are very often isolated by their families and by society, which are organized almost exclusively on the basis of criteria of productive efficiency, according to which a hopelessly impaired life no longer has any value."
(section 64 [entire] )
"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.
". . . 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."
"Even when not motivated by a selfish refusal to be burdened with the life of someone who is suffering, euthanasia must be called a false mercy, and indeed a disturbing "perversion" of mercy. True "compassion" leads to sharing another's pain; it does not kill the person whose suffering we cannot bear. Moreover, the act of euthanasia appears all the more perverse if it is carried out by those, like relatives, who are supposed to treat a family member with patience and love, or by those, such as doctors, who by virtue of their specific profession are supposed to care for the sick person even in the most painful terminal stages.
The choice of euthanasia becomes more serious when it takes the form of a murder committed by others on a person who has in no way requested it and who has never consented to it. The height of arbitrariness and injustice is reached when certain people, such as physicians or legislators, arrogate to themselves the power to decide who ought to live and who ought to die. Once again we find ourselves before the temptation of Eden: to become like God who "knows good and evil" (cf. Gen 3:5). God alone has the power over life and death: "It is I who bring both death and life" (Dt 32:39; cf. 2 Kg 5:7; 1 Sam 2:6). But he only exercises this power in accordance with a plan of wisdom and love. When man usurps this power, being enslaved by a foolish and selfish way of thinking, he inevitably uses it for injustice and death. Thus the life of the person who is weak is put into the hands of the one who is strong; in society the sense of justice is lost, and mutual trust, the basis of every authentic interpersonal relationship, is undermined at its root."
(section 66; emphasis mine)
Lest anyone think that my own call for massive civil disobedience is contrary to Catholic teaching, note the Holy Father's words:
"Laws which authorize and promote abortion and euthanasia are therefore radically opposed not only to the good of the individual but also to the common good; as such they are completely lacking in authentic juridical validity. Disregard for the right to life, precisely because it leads to the killing of the person whom society exists to serve, is what most directly conflicts with the possibility of achieving the common good. Consequently, a civil law authorizing abortion or euthanasia ceases by that very fact to be a true, morally binding civil law.
73. Abortion and euthanasia are thus crimes which no human law can claim to legitimize. There is no obligation in conscience to obey such laws; instead there is a grave and clear obligation to oppose them by conscientious objection. From the very beginnings of the Church, the apostolic preaching reminded Christians of their duty to obey legitimately constituted public authorities (cf. Rom 13:1-7; 1 Pet 2:13-14), but at the same time it firmly warned that "we must obey God rather than men" (Acts 5:29). In the Old Testament, precisely in regard to threats against life, we find a significant example of resistance to the unjust command of those in authority. After Pharaoh ordered the killing of all newborn males, the Hebrew midwives refused. "They did not do as the king of Egypt commanded them, but let the male children live" (Ex 1:17). But the ultimate reason for their action should be noted: "the midwives feared God" (ibid. ). It is precisely from obedience to God—to whom alone is due that fear which is acknowledgment of his absolute sovereignty—that the strength and the courage to resist unjust human laws are born. It is the strength and the courage of those prepared even to be imprisoned or put to the sword, in the certainty that this is what makes for "the endurance and faith of the saints" (Rev 13:10).
"In the case of an intrinsically unjust law, such as a law permitting abortion or euthanasia, it is therefore never licit to obey it, or to "take part in a propaganda campaign in favour of such a law, or vote for it"."
(sections 72-73; my emphasis)
This encyclical provides a wealth of moral wisdom. This is one of the major, major reasons why I became a Catholic. Having been a pro-life activist for eight years prior to my conversion, I wanted to be in the Christian Church that stood for life boldly and without compromise. I dare say that nothing (in the way of an authoritative document) to be found in evangelical or larger Protestantism (where there are indeed many noble and praiseworthy pro-life advocates) can match this document (like Humanae Vitae also) for its majesty and depth of truth and deep understanding of the issues at stake.
If either President Bush (evangelical Protestant) or Governor Jeb Bush (Catholic) had gone in and rescued Terri from imminent death-by-starvation, they would have been violating no biblical or Catholic principle whatsoever. This is not just a "Catholic" thing: it is a general Christian thing that all Christians can (or ought to, I should say) agree upon, in accordance with the Bible and received Christian moral tradition (including Protestantism and Orthodoxy). But (quite predictably) both men decided that man's laws could not be broken, even in such an extraordinary circumstance.
These are perfect, tragic examples of how modern man (even pro-life advocates, Christians, and good men like the two Bushes, who did all they could, legally, to stop the murder) accepts legal positivism: the notion whereby human law is the highest authority over man, rather than the natural law or moral law or God's law, which ought to (and indeed does in fact) lie behind all true and just human law. They were under no moral obligation to obey these obscenely corrupt, anti-life judges or state legislations.
But that's a radical notion, and it will take a long time to sink in. That's why I wrote earlier, that only much more persecution will cause good men to stand up and disobey these abominable, evil pro-death laws. Then something can truly change in our evil, corrupt, humanist, hedonist, idolatrous society.
