Evangelium Vitae §57

⁵⁷ If such great care must be taken to respect every life, even that of criminals and unjust aggressors, the commandment "You shall not kill" has absolute value when it refers to the innocent person. And all the more so in the case of weak and defenceless human beings, who find their ultimate defence against the arrogance and caprice of others only in the absolute binding force of God's commandment. In effect, the absolute inviolability of innocent human life is a moral truth clearly taught by Sacred Scripture, constantly upheld in the Church's Tradition and consistently proposed by her Magisterium. This consistent teaching is the evident result of that "supernatural sense of the faith" which, inspired and sustained by the Holy Spirit, safeguards the People of God from error when "it shows universal agreement in matters of faith and morals". Faced with the progressive weakening in individual consciences and in society of the sense of the absolute and grave moral illicitness of the direct taking of all innocent human life, especially at its beginning and at its end, the Church's Magisterium has spoken out with increasing frequency in defence of the sacredness and inviolability of human life. The Papal Magisterium, particularly insistent in this regard, has always been seconded by that of the Bishops, with numerous and comprehensive doctrinal and pastoral documents issued either by Episcopal Conferences or by individual Bishops. The Second Vatican Council also addressed the matter forcefully, in a brief but incisive passage. Therefore, by the authority which Christ conferred upon Peter and his Successors, and in communion with the Bishops of the Catholic Church, I confirm that the direct and voluntary killing of an innocent human being is always gravely immoral. This doctrine, based upon that unwritten law which man, in the light of reason, finds in his own heart (cf. Rom 2:14-15), is reaffirmed by Sacred Scripture, transmitted by the Tradition of the Church and taught by the ordinary and universal Magisterium. The deliberate decision to deprive an innocent human being of his life is always morally evil and can never be licit either as an end in itself or as a means to a good end. It is in fact a grave act of disobedience to the moral law, and indeed to God himself, the author and guarantor of that law; it contradicts the fundamental virtues of justice and charity. "Nothing and no one can in any way permit the killing of an innocent human being, whether a fetus or an embryo, an infant or an adult, an old person, or one suffering from an incurable disease, or a person who is dying. Furthermore, no one is permitted to ask for this act of killing, either for himself or herself or for another person entrusted to his or her care, nor can he or she consent to it, either explicitly or implicitly. Nor can any authority legitimately recommend or permit such an action". As far as the right to life is concerned, every innocent human being is absolutely equal to all others. This equality is the basis of all authentic social relationships which, to be truly such, can only be founded on truth and justice, recognizing and protecting every man and woman as a person and not as an object to be used. Before the moral norm which prohibits the direct taking of the life of an innocent human being "there are no privileges or exceptions for anyone. It makes no difference whether one is the master of the world or the ?poorest of the poor' on the face of the earth. Before the demands of morality we are all absolutely equal".
