Anointing of the sick
“Are any among you sick? They should call for the elders [priests] of the Church and have them pray over them, anointing them with oil in the name of the Lord. The prayer of faith will save the sick, and the Lord will raise them up, and anyone who has committed sins will be forgiven.” (Jas 5:14- 15)
The oil of the sick is used in the Sacrament of the Sick to bring the strengthening and healing power of Christ, who is at work in the Church by the action of the Holy Spirit.
