The Anointing of the Sick is a sacrament that is administered to a person who is seriously ill, about to undergo serious surgery, who is dying. or who has grown weak because of an advanced age. It used to be called "Last Rites" because it was given close to or at the time of death. It is a sacrament for the living so it cannot be given after death so it is important that it be given when the person can benefit. Once the sacrament is administered, it does not have to be repeated unless a good amount of time has passed.
