What are the works of mercy?
The Catechism of the Catholic Church puts it simply: "The works of mercy are charitable actions by which we come to the aid of our neighbor in his spiritual and bodily necessities" (CCC 2447). They are mercy made concrete — the second great commandment, love your neighbor as yourself, worked out in ordinary acts rather than kept as a private feeling.
Catholic tradition counts fourteen works, arranged in two sevens. The corporal works answer the needs of the body: hunger, thirst, nakedness, sickness, imprisonment, homelessness, and death. The spiritual works answer the deeper needs of the soul: ignorance, doubt, sin, grief, injury, and the need to be prayed for. Both flow from a single source — the mercy God has first shown us. We do not manufacture mercy; we pass on what we have received. That is why the works of mercy are never optional decoration on the Christian life. They are its proof.
The seven corporal works of mercy
The corporal works meet people in their bodily need. Following St. Thomas Aquinas, tradition lists seven:
- Feed the hungry — from a bag of groceries to a seat at your own table.
- Give drink to the thirsty — clean water and relief where it is scarce.
- Clothe the naked — providing what protects a person's warmth and dignity.
- Shelter the homeless — welcoming the stranger and the displaced.
- Visit the sick — presence to the ill, the elderly, the forgotten.
- Visit the imprisoned — remembering those behind bars and their families.
- Bury the dead — honoring the body as a temple of the Holy Spirit.
Six of these come straight from the lips of Christ in Matthew 25, where He identifies Himself with the hungry, the thirsty, the stranger, the naked, the sick, and the prisoner. The seventh, burying the dead, is drawn from the Book of Tobit, who risked his life to bury the abandoned dead of his people (Tobit 1:16–18). Each is a place where love stops being an idea and becomes a hand.
The seven spiritual works of mercy
The spiritual works tend the soul, and they are often harder than the corporal ones because they cost us patience, humility, and courage:
- Instruct the ignorant — sharing the faith with those never taught it, gently and without condescension.
- Counsel the doubtful — steadying someone who is unsure or afraid.
- Admonish sinners — fraternal correction offered in love, never in contempt.
- Comfort the afflicted — accompanying the grieving, the anxious, and the suffering.
- Forgive offenses — releasing the debt, as we ourselves have been forgiven.
- Bear wrongs patiently — enduring the faults of others without bitterness.
- Pray for the living and the dead — carrying others to God, including the souls in purgatory.
To "comfort the afflicted" often means simply being present to someone in emotional or mental pain. A devotion such as the prayer to St. Dymphna, patroness of those who suffer in mind and heart, can accompany — but never replace — professional medical or mental-health care. And to "pray for the living and the dead" is a work every Catholic can do today; the Rosary has carried these intentions for centuries.
Where the works of mercy come from: Matthew 25 and CCC 2447
The corporal works are not a medieval invention; they come from Jesus' own description of the Last Judgment. In Matthew 25:31–46, the King separates the sheep from the goats by a single measure: "For I was hungry and you gave me food, I was thirsty and you gave me drink, a stranger and you welcomed me, naked and you clothed me, ill and you cared for me, in prison and you visited me." Then comes the line that anchors the whole tradition: "Whatever you did for one of these least brothers of mine, you did for me."
The Church gathered these acts, added burying the dead from the Book of Tobit, and paired them with seven spiritual works to form the list of fourteen. The Catechism hands them on in paragraph 2447, and St. Thomas Aquinas set them in the memorable verses still taught today. To serve the needy, then, is to serve Christ Himself — hidden, He says, in "the least" of our brothers and sisters.
Body and soul: is one kind of mercy greater?
Are the spiritual works more important than the corporal ones? St. Thomas Aquinas took up exactly this question. Considered simply, he taught, the spiritual works are the more excellent, because the soul surpasses the body and the gift itself is higher (Summa Theologiae II-II, q. 32, a. 3). Feeding a man for a day is good; leading him toward God is greater still.
But Aquinas added a vital qualification: in a particular case, a bodily work can rightly take precedence. "A man in hunger is to be fed rather than instructed." Mercy reads the situation in front of it. You do not hand a starving person a catechism, and you do not offer only bread to someone dying of despair. The two sevens are not rivals; they are one love reaching the whole person — body and soul together, which is how God made us and how He will raise us.
How to begin practicing the works of mercy
Start where you already are. Pick one corporal and one spiritual work and make it concrete this week: a meal delivered, a lonely relative visited, a grudge finally forgiven, a name added to your daily prayers. Mercy grows by repetition, not by grand gestures.
It also grows from mercy received. We give what we have first been given, so the works of mercy are closely tied to the sacrament of Confession — grace flows out only after it has flowed in. A short examination of conscience can show you exactly where you have withheld mercy: the poor you looked past, the correction you owed and swallowed, the forgiveness you are still refusing. Bring it to the confessional, and the same mercy you receive becomes the mercy you can extend. For a daily rhythm of prayer, examination, and formation that keeps these works in front of you, the Sanctum app is built to help Catholic men live them, not just admire them.
