The Church believes and confesses that among the seven sacraments there is one especially intended to strengthen those who are being tried by illness, the Anointing of the Sick:
From ancient times in the liturgical traditions of both East and West, we have testimonies to the practice of anointings of the sick with blessed oil. Over the centuries the Anointing of the Sick was conferred more and more exclusively on those at the point of death. Because of this it received the name "Extreme Unction." Notwithstanding this evolution the liturgy has never failed to beg the Lord that the sick person may recover his health if it would be conducive to his salvation.
The Anointing of the Sick "is not a sacrament for those only who are at the point of death. Hence, as soon as anyone of the faithful begins to be in danger of death from sickness or old age, the fitting time for him to receive this sacrament has certainly already arrived."130
If a sick person who received this anointing recovers his health, he can in the case of another grave illness receive this sacrament again. If during the same illness the person's condition becomes more serious, the sacrament may be repeated. It is fitting to receive the Anointing of the Sick just prior to a serious operation. The same holds for the elderly whose frailty becomes more pronounced.
