"By the sacred anointing of the sick and the prayer of the priests the whole Church commends those who are ill to the suffering and glorified Lord, that he may raise them up and save them. and indeed she exhorts them to contribute to the good of the People of God by freely uniting themselves to the Passion and death of Christ." (CCC, no. 1499)
Who Receives and Who Administers This Sacrament?
In case of grave illness...
The Anointing of the Sick "is not a sacramentfor 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, no. 1514)
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. (CCC, no. 1515)
" . . . let him call for the presbyters of the Church" Only priests (bishops and presbyters) are ministers of the Anointing of the Sick. It is the duty of pastors to instruct the faithful on the benefits of this sacrament. the faithful should encourage the sick to call for a priest to receive this sacrament. the sick should prepare themselves to receive it with good dispositions, assisted by their pastor and the whole ecclesial community, which is invited to surround the sick in a special way through their prayers and fraternal attention. (CCC, no.1516)
