Anointing of the Sick is the sacrament that is received by those who are ill or suffering. By the sacred anointing and the prayer of the priest, the whole Church commends those who are sick to Christ.
The sick person receives the Holy Spirit’s gifts of strength, faith, peace, and courage, and his or her suffering is united with the suffering of Christ for the building up of the Church ( Catechism of the Catholic Church [CCC], nos. 1520-23). Through the Sacrament of Anointing of the Sick, the Church carries out Jesus’ mission of compassion and healing for the sick. The one who is ill can also be a minister to others. By uniting their suffering to Christ, those who are sick can be signs of faith and witnesses of Christ’s Resurrection to the entire community (Pope John Paul II, Christifideles Laici [ The Vocation and the Mission of the Lay Faithful in the Church and in the World ], no. 54)
