FOLLOWING THE MOST ANCIENT CHRISTIAN TRADITION, the Church insistently recommends that the bodies of the deceased be buried in cemeteries or other sacred places.
In memory of the death, burial and resurrection of the Lord, the mystery that illumines the Christian meaning of death, burial is above all the most fitting way to express faith and hope in the resurrection of the body. By burying the bodies of the faithful, the Church confirms her faith in the resurrection of the body, and intends to show the great dignity of the human body. The burial of the faithful departed in cemeteries or other sacred places encourages family members and the whole Christian community to pray for and remember the dead, while at the same time fostering the veneration of martyrs and saints.
In circumstances when cremation is chosen because of sanitary, economic or social considerations, this choice must never violate the explicitly-stated or the reasonably inferable wishes of the deceased faithful. The Church raises no doctrinal objections to this practice, since cremation of the deceased’s body does not affect his or her soul, nor does it prevent God, in his omnipotence, from raising up the deceased body to new life.
The Church continues to prefer the practice of burying the bodies of the deceased, because this shows a greater esteem towards the deceased. Nevertheless, cremation is not prohibited, “unless it was chosen for reasons contrary to Christian doctrine”. When, for legitimate motives, cremation of the body has been chosen, the ashes of the faithful must be laid to rest in a sacred place, that is, in a cemetery or, in certain cases, in a church or an area, which has been set aside for this purpose, and so dedicated by the competent ecclesial authority.
