Mark refers to the sacrament when he recounts how Jesus sent out the twelve disciples to preach, and "they cast out many demons, and anointed with oil many that were sick and healed them" (Mark 6:13). In his epistle, James says, "Is any among you sick? Let him call for the elders of the church, and let them pray over him, anointing him with oil in the name of the Lord; and the prayer of faith will save the sick man, and the Lord will raise him up; and if he has committed sins, he will be forgiven" (Jas. 5:14–15).
The early Church Fathers recognized this sacrament’s role in the life of the Church. Around A.D. 250, Origen wrote that the penitent Christian "does not shrink from declaring his sin to a priest of the Lord and from seeking medicine . . . [of] which the apostle James says: ‘If then there is anyone sick, let him call the presbyters of the Church, and let them impose hands upon him, anointing him with oil in the name of the Lord; and the prayer of faith will save the sick man, and if he be in sins, they shall be forgiven him’" (Homilies on Leviticus 2:4).
The Sacrament’s Effects
"The special grace of the sacrament of the Anointing of the Sick has as its effects: the uniting of the sick person to the passion of Christ, for his own good and that of the whole Church; the strengthening, peace, and courage to endure in a Christian manner the sufferings of illness or old age; the forgiveness of sins, if the sick person was not able to obtain it through the sacrament of penance; the restoration of health, if it is conducive to the salvation of his soul; the preparation for passing over to eternal life" (CCC 1532).
Does a person have to be dying to receive this sacrament? No. The Catechism says, "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" (CCC 1514).
