Those who approach the sacrament of Penance obtain pardon from God’s mercy for the offense committed against him, and are, at the same time, reconciled with the Church which they have wounded by their sins and which by charity, by example, and by prayer labors for their conversion. – CCC 1422
The sacrament of the Anointing of the Sick is administered to the dying as well as to those who are gravely ill or about to undergo a serious operation. This sacrament of mercy and healing offers prayers for the recovery, but its primary intention is to give spiritual strength and calm the soul of the one suffering from illness. Traditionally, this sacrament was referred to as Extreme Unction or Last Rites.
Anointing at Risen Christ
Anointing is not to be delayed to the last minute. A person who has been anointed once does not need to be anointed again within the same illness. It is also important for someone who is anointed to be prepared to go to confession when the priest arrives (if they are able).
