The Catechism of the Catholic Church teaches us, "'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,375).
Illness and suffering have always been among the most serious challenges faced in human life. When someone is ill, they confront their powerlessness, limitations, and mortality. Every illness can offer a glimpse of death.
