CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 1506–1509

1506 Christ invites his disciples to follow him by taking up their cross in their turn. By following him they acquire a new outlook on illness and the sick. Jesus associates them with his own life of poverty and service. He makes them share in his ministry of compassion and healing: "So they went out and preached that men should repent. And they cast out many demons, and anointed with oil many that were sick and healed them."
1507 The risen Lord renews this mission ("In my name . . . they will lay their hands on the sick, and they will recover.") and confirms it through the signs that the Church performs by invoking his name. These signs demonstrate in a special way that Jesus is truly "God who saves."
1508 The Holy Spirit gives to some a special charism of healing so as to make manifest the power of the grace of the risen Lord. But even the most intense prayers do not always obtain the healing of all illnesses. Thus St. Paul must learn from the Lord that "my grace is sufficient for you, for my power is made perfect in weakness," and that the sufferings to be endured can mean that "in my flesh I complete what is lacking in Christ's afflictions for the sake of his Body, that is, the Church."
1509 "Heal the sick!" The Church has received this charge from the Lord and strives to carry it out by taking care of the sick as well as by accompanying them with her prayer of intercession. She believes in the life-giving presence of Christ, the physician of souls and bodies. This presence is particularly active through the sacraments, and in an altogether special way through the Eucharist, the bread that gives eternal life and that St. Paul suggests is connected with bodily health.
