Catechism of the Catholic Church

554 Part Three Respect for the dead 2299 The dying should be given attention and care to help them live their last moments in dignity and peace. They will be helped by the prayer of their relatives, who must see to it that the sick receive at the proper time the sacraments that prepare them to meet the living God. 2300 The bodies of the dead must be treated with respect and charity, in faith and hope of the Resurrection. The burial of the dead is a corporal work of mercy; 92 it honors the children of God, who are temples of the Holy Spirit. 2301 Autopsies can be morally permitted for legal inquests or scientific research. The free gift of organs after death is legitimate and can be meritorious. The Church permits cremation, provided that it does not dem­ onstrate a denial of faith in the resurrection of the body. 93 III. S afeguarding P eace Peace 2302 By recalling the commandment, “You shall not kill,” 94 our Lord asked for peace of heart and denounced murderous anger and hatred as immoral. Anger is a desire for revenge. “To desire vengeance in order to do evil to someone who should be punished is illicit,” but it is praiseworthy to impose restitution “to correct vices and maintain justice.” 95 If anger reaches the point of a deliberate desire to kill or seriously wound a neighbor, it is gravely against charity; it is a mortal sin. The Lord says, “Everyone who is angry with his brother shall be liable to judgment.” 96 2303 Deliberate hatred is contrary to charity. Hatred of the neighbor is a sin when one deliberately wishes him evil. Hatred of the neighbor is a grave sin when one deliberately desires him grave harm. “But I say to you, Love your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven.” 97 92 Cf.
