ACCORDING TO THE CATECHISM
According to the Catechism of the Catholic Church #2447, the Works of Mercy are charitable actions by which we come to the aid of our neighbor in his or her spiritual and bodily necessities. The Corporal Works of Mercy are found in the teachings of Jesus and give us a model for how we should treat all others, as if they were Christ in disguise. The Spiritual Works of Mercy have long been a part of the Christian tradition, appearing in the works of theologians and spiritual writers throughout history.
Corporal Works of Mercy:
Feed the hungry, give drink to the thirsty, clothe the naked, shelter the homeless, visit the sick, visit the imprisoned, and bury the dead.
Spiritual Works of Mercy:
Teach others about God and the Faith, counsel the doubtful, encourage reconciliation with God and others, bear wrongs patiently, forgive offenses willingly, comfort the afflicted, pray for the living and the dead.
