Given the Gospel this weekend, and its relation to human sickness, we would like to give the following paragraphs from the Catechism of the Catholic Church as a reminder of what the Church teaches in this regard.
Illness in human life
1500 Illness and suffering have always been among the gravest problems confronted in human life. In illness, man experiences his powerlessness, his limitations, and his finitude. Every illness can make us glimpse death.
1501 Illness can lead to anguish, self-absorption, sometimes even despair and revolt against God. It can also make a person more mature, helping him discern in his life what is not essential so that he can turn toward that which is. Very often illness provokes a search for God and a return to him.
The sick person before God
1502 The man of the Old Testament lives his sickness in the presence of God. It is before God that he laments his illness, and it is of God, Master of life and death, that he implores healing. Illness becomes a way to conversion; God’s forgiveness initiates the healing. It is the experience of Israel that illness is mysteriously linked to sin and evil, and that faithfulness to God according to his law restores life: “For I am the Lord, your healer.” The prophet intuits that suffering can also have a redemptive meaning for the sins of others. Finally Isaiah announces that God will usher in a time for Zion when he will pardon every offense and heal every illness.
Christ the physician
1503 Christ’s compassion toward the sick and his many healings of every kind of infirmity are a resplendent sign that “God has visited his people” and that the Kingdom of God is close at hand. Jesus has the power not only to heal, but also to forgive sins; he has come to heal the whole man, soul and body; he is the physician the sick have need of. His compassion toward all who suffer goes so far that he identifies himself with them: “I was sick and you visited me.” His preferential love for the sick has not ceased through the centuries to draw the very special attention of Christians toward all those who suffer in body and soul. It is the source of tireless efforts to comfort them.
1504 Often Jesus asks the sick to believe. He makes use of signs to heal: spittle and the laying on of hands, mud and washing. The sick try to touch him, “for power came forth from him and healed them all.” and so in the sacraments Christ continues to “touch” us in order to heal us.
1505 Moved by so much suffering Christ not only allows himself to be touched by the sick, but he makes their miseries his own: “He took our infirmities and bore our diseases.” But he did not heal all the sick. His healings were signs of the coming of the Kingdom of God. They announced a more radical healing: the victory over sin and death through his Passover. On the cross Christ took upon himself the whole weight of evil and took away the “sin of the world,” of which illness is only a consequence. By his passion and death on the cross Christ has given a new meaning to suffering: it can henceforth configure us to him and unite us with his redemptive Passion.
A sacrament of the sick
1511 The Church believes and confesses that among the seven sacraments there is one especially intended to strengthen those who are being tried by illness, the Anointing of the Sick:
1512 From ancient times in the liturgical traditions of both East and West, we have testimonies to the practice of anointings of the sick with blessed oil. Over the centuries the Anointing of the Sick was conferred more and more exclusively on those at the point of death. Because of this it received the name “Extreme Unction.” Notwithstanding this evolution the liturgy has never failed to beg the Lord that the sick person may recover his health if it would be conducive to his salvation.
