What the Saints Teach About the Battle Against Gluttony

Gluttony is not the pleasure of eating

The first concern of the saints is to clear up a misunderstanding: God made food good, and the pleasure of eating is part of His gifts. Christ ate and drank to the point that He was accused of being “a glutton and a drunkard” (Mt 11:19)^[2]; He turned water into wine at Cana and multiplied the loaves. Creation is declared “very good,” and the Apostle warns those who forbid certain foods: “Everything God created is good, and nothing is to be rejected if it is received in thanksgiving” (1 Tim 4:4)^[3]. The sin, therefore, does not lie in the food nor in the pleasure it provides, but in the disorder of the appetite.

“The kingdom of God does not consist in questions of food or drink; it is righteousness, peace, and joy in the Holy Spirit.”
— Letter to the Romans 14:17^[4]

It is this distortion that the saints seek to root out: making what should be a means—eating to live—into an end pursued for its own sake. “Food is meant for the stomach and the stomach for food,” writes Saint Paul (1 Cor 6:13)^[5]; the tragedy begins when man reverses the order and lives for the stomach.

Saint Thomas Aquinas’s definition: a disordered appetite

Saint Thomas Aquinas (1225–1274) gathered this entire tradition in question 148 of the Secunda Secundae, entirely devoted to gluttony (De gula). His definition is clear: gluttony is not the desire to eat and drink, but a disordered desire to eat and drink.

“Gluttony does not mean every desire to eat and drink, but a disordered desire. Now a desire is said to be disordered when it departs from the order of reason, in which consists the good of moral virtue.”
— according to Saint Thomas Aquinas, Summa Theologica, II-II, q. 148, a. 1^[6]

The key word is disordered (inordinatus). Thomas does not consider eating and drinking to be evils: the appetite itself is willed by God to preserve life. Sin begins when this appetite exceeds the measure of reason—either by quantity (eating too much), by quality (seeking overly elaborate or refined dishes), or by manner (eating too early, too greedily). Gluttony, he specifies, is a capital vice: not the gravest of sins, but a source from which others flow, because the attraction of the pleasures of the table leads the soul into many derailments^[7].

Distinguishing need, legitimate pleasure, and gluttony

Spiritual masters emphasize a distinction that conscience often confuses, because gluttony excels at disguising itself as need or conviviality.

Reading: the virtue of temperance holds the middle ground between two extremes—the gluttony that yields without measure, and the rigorism that condemns what God has made good. The test is not absolute quantity, which varies according to work, health, and state of life, but the place of the heart: am I master of my appetite, or its servant?

Why the saints call it the “first battle”

It was the monk Evagrius Ponticus (c. 345–399) who first listed the eight “thoughts” (logismoi) that generate all sins, placing gastrimargia—gluttony—at the head. His Latin disciple, Saint John Cassian (c. 360–435), transmitted this teaching to the West in his Institutes of the Coenobia, whose book V is entirely devoted to the spirit of gluttony (De spiritu gastrimargiae). For Cassian, this is no accident: one must fight the belly first, because it is the most immediate bodily root, and one cannot hope to overcome subtler passions while enslaved to the coarsest^[9].

“We cannot enter into the battle of interior struggles if we have not first triumphed, on the manifest battlefield, over the gluttony of the belly.”
— according to Saint John Cassian, Institutes of the Coenobia, book V^[10]

The order is pedagogical: he who does not know how to deny himself a dish will not know how to deny himself resentment, vanity, or covetousness. The battle of the belly is the elementary school of all self-mastery—the alphabet of asceticism before the grammar of higher virtues.

“Too soon, too much, too costly, too eagerly, with too much fuss”

The most famous analysis of gluttony comes from Saint Gregory the Great (c. 540–604), pope and doctor of the Church, in his Morals on Job. He observes that one does not sin only by excess of quantity: one can eat little and still sin, by the manner of eating. He distinguishes five ways in which gluttony tempts the heart, which scholastic tradition has preserved in a Latin formula of five adverbs.

“Gluttony tempts us in five ways: sometimes it anticipates the meal time; sometimes it seeks more refined dishes; sometimes it demands that the food be prepared with more care; sometimes it exceeds measure in quantity; sometimes it burns with excessive ardor of desire.”
— from Saint Gregory the Great, Morals on Job, XXX, 18^[11]

The following table unfolds this framework, which has served for fourteen centuries as a guide for examination of conscience.

Note: this analysis frees one from legalism. One can eat little and be gluttonous (through greed or demandingness); one can eat more without being so (out of real need). The sin is not on the plate but in the heart’s relation to the plate.

The Trap of Refinement: The Gluttony of the Delicate

Saint Gregory here targets a fault that devout souls often believe themselves immune to: the gluttony of the “little but exquisite.” One can fast in quantity and yet sin in quality, constantly demanding better and different, turning every meal into an occasion for complaint or fuss. As the monastic tradition already noted, the devil did not tempt Adam with a feast, but with a single fruit: it was not the mass of food that lost the first man, but the disordered desire for one forbidden bite^[12]. The most persistent gluttony is not that of the glutton, but the refined and anxious glutton who is never satisfied.

The Forbidden Fruit: The First Bite

The Fathers read the Fall itself through the prism of gluttony. The Genesis account shows Eve considering the forbidden tree not first as an abstract transgression, but as an object of sensible desire.

“The woman saw that the fruit of the tree must have been tasty, that it was a delight to the eyes, and that the tree was to be desired, since it gave understanding. She took of its fruit and ate.”
— Book of Genesis 3:6^[13]

Patristic tradition noted that the first disobedience passed through the mouth, and that it is no accident that Redemption begins with a fast: the second Adam, in the desert, refuses precisely what the first had grasped. Where the belly had opened the door to sin, Christ’s abstinence closes it. This typology governs all Lenten spirituality: as the Lenten preface sings, the fast of the body is the remedy that represses vices.

Esau: A Birthright for a Bowl of Lentils

No figure has served the saints more to illustrate the folly of gluttony than Esau, who sold his birthright — his blessing, his future, his share of the promise — for a bowl of lentils, because he was hungry and would not wait.

“Esau answered, ‘I am dying! What use is my birthright to me?’ ... He ate and drank, then rose and went away. Thus Esau showed contempt for his birthright.”
— Book of Genesis 25:32-34^[14]

The Letter to the Hebrews makes him the typical warning against the profane who sacrifices the eternal for the immediate: “See that there is no fornicator or profane person, like Esau who sold his birthright in exchange for a single dish” (Heb 12:16)^[15]. This is the essence of gluttony: preferring the present satisfaction of the belly to a far greater good.

“The Graves of Lust”: Israel in the Desert

The desert struggle offers the Fathers another striking image. Weary of manna, the people demand meat with such greed that the place of their punishment was named Qibroth-ha-Taava — “the graves of lust.”

“The meat was still between their teeth, they had not finished chewing it when already the anger of the Lord blazed out against the people... So that place was called Qibroth-ha-Taawa (that is: Tombs of Craving), for there they buried the crowd of those who had been seized with craving.”
— Book of Numbers 11:33-34^[16]

Psalm 78 comments: they tempted God by demanding food according to their desire, and spoke against Him (Ps 78:18-19). Gluttony here appears linked to distrust: not being content with what God gives, demanding something else, and making appetite a rebellion against Providence.

The Rich Man Who “Feasted Sumptuously”

In the Gospel, the clearest portrait of the glutton is the rich man of the parable of Lazarus, whose only explicit crime is feasting every day while a poor man dies at his gate.

“There was a rich man, dressed in purple and fine linen, who feasted sumptuously every day. At his gate lay a poor man named Lazarus, who was covered with sores...”

— Gospel according to Saint Luke 16:19-20^[17]

Saint John Chrysostom, from the first of his Homilies on Lazarus, teaches that the rich man’s first crime was “this cruelty, this unparalleled inhumanity”: letting his neighbor perish of hunger “when one overflows with every delight”: the abundant table had weighed down his heart to the point of blinding him. Gluttony is here presented as a hardness: the sated belly no longer has room for compassion. This is the link tradition draws between excess at table and forgetfulness of almsgiving — a theme that touches on the neighboring battle against avarice.

Christ’s Response in the Desert: “Man Does Not Live by Bread Alone”

This entire series of falls finds its answer in the desert, where Christ, after forty days of fasting, repels the first temptation — that of the belly itself.

“The tempter came to him and said, ‘If you are the Son of God, command these stones to become loaves of bread.’ But Jesus answered, ‘It is written, Man does not live by bread alone, but by every word that proceeds from the mouth of God.’”
— Gospel according to Saint Matthew 4:3-4^[18]

Christ does not deny hunger — he is truly hungry — but he refuses to make it master. His response establishes the hierarchy that gluttony overturns: food is good, but it is not life; the life of man comes first from God. The entire victory of the saints over gluttony will consist in restoring this order.

The Daughters of Gluttony According to Saint Gregory and Saint Thomas

If the saints feared a seemingly modest vice so much, it is because they saw it generate other sins. Saint Gregory the Great, taken up by Saint Thomas (Summa, II-II, q. 148, a. 6), lists five “daughters” of gluttony — the vices born from an overfilled belly.

Note: Gregory categorizes these effects according to whether they affect the soul (dulled reason, disordered joy), speech (chatter, buffoonery), or the body (impurity). The common thread: a mind weighed down by the belly loses its subtlety, vigilance, and recollection.

The Belly and the Flesh: Why Gluttony Opens the Door to Lust

The most consistently emphasized link by the saints is the one that unites gluttony to lust. The monks said these two vices are “sisters” because they both target the body, and the second almost always follows the first: a full and inflamed belly awakens the desire of the flesh. Saint John Climacus, in his Ladder of Divine Ascent, devotes the fourteenth step to “the mistress of the belly” and draws from it a famous spiritual law.

He who has mastered his belly, Climacus teaches, advances swiftly toward chastity.
— according to Saint John Climacus, The Ladder of Divine Ascent, step 14^[19]

This is why all masters of the spiritual combat place sobriety at the foundation of purity: one does not keep the heart if one does not keep the table. The fight against gluttony is thus the first bulwark against lust, and one of the conditions for purity of heart.

Hebetude of the Mind: A Weighed-Down Heart No Longer Prays

The last “daughter” — hebetudo mentis, the hebetude of the mind — directly affects the life of prayer. Christ himself warned against this dulling:

“Take heed to yourselves, lest your heart be weighed down with carousing, drunkenness, and cares of this life.”
— Gospel according to Saint Luke 21:34^[20]

The Desert Fathers had verified it: an overloaded body becomes heavy for prayer, drowsy at vigil, distracted during lectio. As the desert elders said, the sated belly hardly gives birth to fine thoughts. Gluttony does not only attack chastity: it dulls the soul’s attention to God. This is why fasting has always been associated with prayer, as the condition of a heart that is light and awake.

Cassian: First conquer the belly, but with discernment

For Cassian, victory over gluttony is not a matter of austere records, but of discernment (discretio). He warns against the opposite excess—a immoderate fast that ruins health and feeds pride—as much as against softness. The measure is judged by a simple sign: food must sustain the body without weighing down the spirit.

“We must take food in such quantity that it sustains life, not such that it burdens the soul.”
— according to Saint John Cassian, Institutes of the Coenobia, Book V^[21]

Cassian’s golden rule is to rise from the table before being fully satisfied: always keep a little hunger, so that the body remains a servant and not a master.

Saint Benedict: measure, wine, and “crapula”

Saint Benedict (c. 480–547), in his Rule, translated this discernment into a law of daily life. Chapters 39 and 40 set the measure of food and drink: two cooked dishes, one pound of bread, a hemina of wine per day—but above all the warning, borrowed from Christ, against crapula, excess at the table.

“Nothing is so contrary to every Christian as excess at the table, according to this word of our Lord: ‘Take heed that your hearts be not weighed down with surfeiting.’”
— Saint Benedict, Rule, ch. 39^[22]

Benedict does not impose heroic austerity: he forbids excess and prescribes measure, leaving to each, according to their work and health, enough to live. His wisdom is to make sobriety not a performance, but an ordinary discipline, integrated into a life of prayer and work. Regarding wine, he takes up the word of Scripture: “Wine makes even the wise apostatize” (Sir 19:2), and prefers abstinence rather than exposing oneself to satiety and drunkenness^[23].

Saint Augustine: eating as one takes medicine

No saint has described with more subtlety the inner difficulty of the struggle than Saint Augustine (354–430). In Book X of his Confessions, he confesses that hunger and thirst are real pains that must be relieved, but that the passage from need to satiety is itself a pleasure where a trap is set.

“You taught me to take food only as medicine. But when I pass from the anxiety of need to the rest that follows its satisfaction, the trap of concupiscence awaits me at the passage; for this passage itself is a pleasure, and there is no other way, and it is necessity that drives me there.”
— Saint Augustine, Confessions, Book X, ch. 31^[24]

Augustine here formulates the crux of the problem: one cannot not eat, and one cannot eat without pleasure; the boundary between need and gluttony is shifting, for what suffices for necessity does not suffice for pleasure. The solution is therefore not a mechanical rule, but a loving vigilance: to receive food as a remedy given by God, and to watch that the remedy does not become an end in itself.

The ancients: rise from the table still hungry

The wisdom of the Desert Fathers is summed up in a few maxims preserved in the collections (Apophthegmata). Their constant principle is not to eat nothing, but never to be completely satisfied, to eat at fixed times, and to avoid singularity—neither more austere than the brothers out of pride, nor softer out of cowardice. They recommended eating each day a little less than one’s hunger, so as to remain free. Mastery of the belly is presented as a freedom regained: he who no longer depends on his table fears nothing from it.

Fasting and Abstinence: Taking Back the Helm

The primary and proper weapon against gluttony is fasting, practiced by Christ, the apostles, and all the saints. It is not contempt for food, but taking control: by voluntarily denying oneself, the soul reminds the body who is in charge, and redirects to God the hunger it learns to endure.

“And when you fast, do not look gloomy, like the hypocrites... But when you fast, anoint your head and wash your face; thus your fast will not be known to men, but only to your Father who is present in the greatest secrecy.”
— Gospel according to Saint Matthew 6:16-18^[25]

Christian fasting has three traditional purposes: to master the body, to repair sins, and to pray with greater strength. It is always accompanied by charity — “Is not this the fast that pleases me, says the Lord: to share your bread with the hungry” (Is 58:6-7)^[26] — so as not to become a sterile performance.

Temperance and Sobriety: The Right Measure

Beyond occasional fasting, the permanent virtue that governs appetite is temperance, one of the four cardinal virtues. It does not extinguish desire; it regulates it, keeping it within the order of reason and faith. The Catechism describes it as the virtue that “moderates the attraction of pleasures and provides balance in the use of created goods” (CCC 1809)^[27]. Saint Paul gives the watchword for this discipline:

“I treat my body harshly, I make it my slave, lest after proclaiming the Gospel to others I myself should be disqualified.”
— First Letter to the Corinthians 9:27^[28]

The full development of this virtue can be read in What the Saints Say About Temperance; gluttony is its most immediate opposing vice, just as avarice opposes liberality.

Thanksgiving: Receiving Food as a Gift

The antidote for the heart is not only deprivation but gratitude. The glutton takes food as a right or a refuge; the saint receives it as a gift and returns it to God through thanksgiving. This is why the Church blesses the table: “Whatever you do: eating, drinking, or any other action, do it for the glory of God” (1 Cor 10:31)^[29]. The blessing of the meal, the Benedicite, is not a mere formula: it puts food back in its place — a means, not an end — and disarms gluttony at its root by directing the pleasure received from the gift toward the Giver. Here we return to the battle of thanksgiving, which heals the heart of greed by teaching it to receive everything.

Saint Francis de Sales: Sobriety Without Scruples

For the faithful living in the world, Saint Francis de Sales (1567–1622) gave in his Introduction to the Devout Life the most cited rule of balance. He rejects both laxity and scrupulosity, and brings everything back to the freedom of the heart.

“If you can bear fasting, it is good to practice it somewhat... But always keep your heart, your body, and your tongue in moderation.”
— from Saint Francis de Sales, Introduction to the Devout Life, III, ch. 23^[30]

His teaching is to eat what is served to you, simply, without making it a subject of complaint or seeking — for, he says, “it is better to eat without choice what is presented to you... than always to choose the worst” through a false mortification that is only another form of self-love. True sobriety is free: neither a slave to pleasure nor a slave to one’s own austerities. It is the same spirit of freedom found in the detachment of the heart.

In the end, the voice of the saints on gluttony says one consistent thing: it is the most humble and daily battle, the one that begins anew at every meal. No one triumphs over it once and for all, because unlike avarice or anger, one cannot simply avoid the occasion: one must eat to live, and therefore face each day, at the table, the shifting boundary between need and disordered desire. This is why the Fathers made it the first battle: not the most glorious, but the most formative, the elementary school where the soul learns to say no to the most pressing appetites in order to say yes to God.

But this asceticism is not a hatred of the body nor a contempt for God’s gifts. The saint is not the one who no longer eats, but the one who eats freely — master enough of his table to leave it without regret, grateful enough to see it as a gift and not an idol. Where gluttony weighs down, dissipates, and blinds, sobriety makes the mind light, the heart vigilant, and the soul free to pray. Christ hungers in the desert and refuses stones turned into bread; He then eats and drinks with sinners; finally, He breaks the bread of His own Body. The whole battle is about reaching this freedom: no longer living for the belly, but receiving the daily bread from the Father’s hands, awaiting the only satisfaction that never disappoints — the one of which it is said: “Blessed are those who hunger and thirst for righteousness, for they shall be satisfied” (Mt 5:6).
