3. Intentionally causing one’s own death, or suicide, is therefore equally as wrong as murder; such an action on the part of a person is to be considered as a rejection of God’s sovereignty and loving plan. Furthermore, suicide is also often a refusal of love for self, the denial of a natural instinct to live, a flight from the duties of justice and charity owed to one’s neighbor, to various communities or to the whole of society – although, as is generally recognized, at times there are psychological factors present that can diminish responsibility or even completely remove it. However, one must clearly distinguish suicide from that sacrifice of one’s life whereby for a higher cause, such as God’s glory, the salvation of souls or the service of one’s brethren, a person offers his or her own life or puts it in danger (cf. Jn. 15:14).
Gospel of Life, Pope John Paul II, March 25, 1995.
66. Suicide is always as morally objectionable as murder. The Church’s tradition has always rejected it as a gravely evil choice. 83 Even though a certain psychological, cultural and social conditioning may induce a person to carry out an action which so radically contradicts the innate inclination to life, thus lessening or removing subjective responsibility, suicide, when viewed objectively, is a gravely immoral act. In fact, it involves the rejection of love of self and the renunciation of the obligation of justice and charity towards one’s neighbour, towards the communities to which one belongs, and towards society as a whole. 84 In its deepest reality, suicide represents a rejection of God’s absolute sovereignty over life and death, as proclaimed in the prayer of the ancient sage of Israel: “You have power over life and death; you lead men down to the gates of Hades and back again” (Wis 16:13; cf. Tob 13:2).
Everyone is responsible for his life before God who has given it to him. It is God who remains the sovereign Master of life. We are obliged to accept life gratefully and preserve it for his honor and the salvation of our souls. We are stewards, not owners, of the life God has entrusted to us. It is not ours to dispose of.
Suicide contradicts the natural inclination of the human being to preserve and perpetuate his life. It is gravely contrary to the just love of self. It likewise offends love of neighbor because it unjustly breaks the ties of solidarity with family, nation, and other human societies to which we continue to have obligations. Suicide is contrary to love for the living God.
If suicide is committed with the intention of setting an example, especially to the young, it also takes on the gravity of scandal. Voluntary co-operation in suicide is contrary to the moral law. Grave psychological disturbances, anguish, or grave fear of hardship, suffering, or torture can diminish the responsibility of the one committing suicide.
We should not despair of the eternal salvation of persons who have taken their own lives. By ways known to him alone, God can provide the opportunity for salutary repentance. The Church prays for persons who have taken their own lives.
