The Sacrament of the Anointing of the Sick “is especially intended to strengthen those who are being tried by illness” (CCC 1511). Along with the Sacrament of Reconciliation, Anointing of the Sick is one of the two Sacraments of Healing.
The sacrament of Anointing of the Sick is “given to those who are seriously ill by anointing them on the forehead and hands with duly blessed oil – pressed from olives or from other plants – saying, only once: ‘Through this holy anointing may the Lord in his love and mercy help you with the grace of the Holy Spirit. May the Lord who frees you from sin save you and raise you up’” (CCC 1513).
The Anointing of the Sick “is not a sacrament only for those 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” (CCC 1514).
One can receive the Anointing of the Sick several times in one’s life. Therefore, it make sense for young people to ask for this sacrament also, if, for example, they are about to undergo a serious operation or terminally ill.
There are five effects of the Anointing of the Sick. To learn about the effects of the Sacrament of Healing, see the following video by Dr. Ben Akers, from the Augustine Institute
