Of all the passions, anger is probably the one the saints have described with the greatest unanimity, because they all fought it — and several of them, among the gentlest, originally had fiery temperaments. As early as the 4th century, in the deserts of Egypt, the first monks ranked anger among the most destructive thoughts: not the brief emotion that passes through the soul, but the vice that settles there, “blinding the eyes of the heart” and abruptly stopping prayer, discernment, and peace[1].
From this diagnosis by the Desert Fathers, an unbroken chain of masters has passed down the analysis and remedies: Evagrius Ponticus, who classified anger among the eight thoughts; Saint John Cassian, who devoted an entire book to it and insisted that one “uproot the root”; Saint John Climacus, who traced its genealogy in his Ladder; Saint Benedict and Saint Augustine, who made it a law of monastic peace; Saint Thomas Aquinas, who distinguished good anger from bad; and finally Saint Francis de Sales, a conquered angry man who became the doctor of gentleness. And in recent times, Pope Francis (2013–2025), who devoted an entire catechesis to it on January 31, 2024[2].
This article gathers this voice: what the saints, doctors, and the magisterium have said about the battle against anger, each with their own emphasis. It does not address the practical “how” — the nature of anger, its distinctions from holy indignation, and the details of the remedies are covered in the article How to Grow in the Battle Against Anger, to which we refer. Here, we listen to the saints, from the Egyptian desert to the Rome of Pope Francis (2013–2025).
Why Listen to the Saints on the Battle Against Anger?
A Passion Everyone Has Faced
Anger was not studied by theorists exempt from it, but by men who felt it rise within them and who tamed it. The desert monks observed it in themselves, in the face-to-face solitude of the cell; Saint Francis de Sales, one of the gentlest doctors, confessed a bilious and quick nature that took him more than twenty years to master[3]. This gives their words an authority of experience: they do not speak of a theoretical evil, but of an enemy they faced hand to hand, and conquered.
A Remarkable Unanimity, from the Desert to Our Day
Put together, their texts form a single doctrine, astonishingly stable over sixteen centuries. The same evil — anger that blinds and divides —, the same symptoms — disturbed judgment, smoldering resentment, refusal to forgive —, and the same remedies — gentleness, patience, peace made before nightfall — appear with Evagrius and Cassian in the 4th century, with Climacus and Benedict, with Thomas Aquinas in the 13th, with Francis de Sales in the 17th, and even in Pope Francis’s catechesis in 2024. This continuity is not a coincidence of scholars copying each other: it is the mark of a true observation, verified by generations of souls who have fought the same battle.
All Echoes of Scripture and the Christ “Gentle and Humble of Heart”
Before the saints, there is Scripture. The Fathers did not invent the doctrine of the battle against anger: they received it from the Bible, which already distinguishes the passing impulse from settled sin. Saint Paul gives in advance the watchword that all will repeat after him:
“If you are angry, do not fall into sin: do not let the sun go down on your anger; give the devil no foothold.” — Letter to the Ephesians 4:26-27[4]
Saint James gives the spiritual reason — man’s anger always fails, by itself, to accomplish the justice it claims to serve:
“Everyone must be quick to listen, slow to speak, slow to anger, for man’s anger does not accomplish what is just in God’s eyes.” — Letter of Saint James 1:19-20[5]
And Christ himself, warning that anger against a brother already falls under judgment[6], gave the model toward which the whole battle points: not hardness, but his own gentleness:
“Take my yoke upon you, and learn from me, for I am gentle and humble in heart, and you will find rest for your souls.” — Gospel according to Saint Matthew 11:29[7]
All that the saints say about the battle against anger is but a lived commentary on these words. One can verify this by browsing, century after century, their great chorus.
The Desert Fathers: Diagnosing Anger
Evagrius Ponticus: Anger, Enemy of Prayer
It all begins with Evagrius Ponticus (c. 345–399), a monk in the desert of Kellia, the first to organize the inner struggle around eight evil thoughts, among which anger is one of the most violent[8]. His decisive contribution was linking anger to prayer: as long as resentment smolders, prayer is impossible. In his Chapters on Prayer, he makes it an absolute condition:
“If you desire to pray properly, do not grieve any soul; otherwise, your efforts are in vain. […] The resentment of insults makes the intellect wild, and one who prays while holding a grudge is like one who sows in the sea.”
— Evagrius Ponticus, Chapters on Prayer[9]
For Evagrius, anger is not merely a moral evil: it is a fog that renders the soul incapable of God. The nurtured memory of an offense—the resentment (μνησικακία)—is its most tenacious form and the first to be uprooted by anyone who wishes to pray. This insight would govern the entire tradition: one does not fight anger to have a good character, but to keep the soul clear before God.
Saint John Cassian: “Uprooting the Poisoned Root”
It was Saint John Cassian (c. 360–435) who brought the monastic science of the East to the Latin West. In his Institutes of the Coenobia, he devotes the entire eighth book to “the spirit of anger,” giving the most complete portrait of it in Christian antiquity. His principle is radical—anger is not to be moderated, it must be uprooted:
“Anger is the fourth vice we must fight, and from which we must uproot the poisoned root from our souls. As long as this passion rules our heart and darkens our inner sight with its thick shadows, we cannot acquire the clarity of discernment nor reach true contemplation.”
— Saint John Cassian, Institutes of the Coenobia, VIII, 1[10]
Cassian then dismantles the classic excuse: “I get angry for a just cause.” Citing Saint Paul—“Put away all anger from among you” (Eph 4:31)—he allows no exceptions:
“When the Apostle says, ‘Put away all anger from among you,’ he does not except that which seems useful and necessary to us. If one must rebuke a guilty brother, let it be done with moderation, lest in trying to heal someone of a slight fever, one falls into a more serious illness through the blindness of anger.”
— Saint John Cassian, Institutes of the Coenobia, VIII, 5[11]
Then comes the image that sums up his entire teaching—the beam that blinds, whether made of base or precious metal:
“Whatever the cause of anger, this violent passion blinds the eyes of the heart and places, through the harm it causes, like a beam that prevents it from seeing the sun of justice. Whether this obstacle is gold, lead, or some other metal, the sight always suffers, and the richness of the metal makes no difference in the blindness.”
— Saint John Cassian, Institutes of the Coenobia, VIII, 6[12]
The image is decisive: it does not matter if anger is adorned with good reasons—zeal, justice, correction of others—its nature remains to blind. Cassian does not deny all use of anger, however: he preserves one single legitimate anger, the one turned against one’s own vices and against anger itself, according to the psalm:
“We can be angry at the anger we have had toward our brother: this is the way to resist its bad counsel. ‘Be angry, and do not sin,’ says the Prophet (Ps 4:5).”
— Saint John Cassian, Institutes of the Coenobia, VIII, 7[13]
Like Paul, he finally makes reconciliation before nightfall the law of the monk, commenting extensively on “do not let the sun go down on your anger”: letting anger last through the night is letting it “set its traps deep in our souls” and darken within us the true Sun of justice[14]. It is through him that this teaching became the common heritage of all Western monasticism.
Saint John Climacus: The Genealogy of Anger and the Crown of Gentleness
In the 6th–7th centuries, at the monastery of Sinai, Saint John Climacus (c. 579–649) gathered the wisdom of the desert in The Ladder of Divine Ascent, where the ascent to God is climbed step by step. He dedicates the eighth step to non-anger and gentleness, and does something unique there: he puts anger itself on trial, demanding it name its lineage. The response outlines a spiritual genealogy of striking precision:
“Tell us, foolish and shameless passion of anger, the name of your father, the mother who bore you, and the corrupt children born of you… It seems I hear it answer: ‘The first who contributes to my existence is pride. I also have several mothers: vainglory, greed, intemperance, lust. My daughters are the thought of insults, hatred, quarrels, and enmities. But the virtue that harms me most is humility.’” — Saint John Climacus, The Ladder of Divine Ascent, step 8[15]
Everything is said: anger is born of pride, feeds on other passions, and gives birth to hatred. Its mortal enemy is humility. Climacus then shows, through an unforgettable scene, that victory has degrees. Three monks receive the same insult; all endure it, but at different heights:
“One day, three monks received the same insult. One felt stung but endured it silently; another rejoiced inwardly but grieved out of charity for the one who had wronged him; the third forgot himself entirely to weep only for his brother’s fault. There were seen three virtues: fear of God, hope, and love.” — Saint John Climacus, The Ladder of Divine Ascent, step 8[16]
At the summit of this ascent, Climacus places a reward he calls by a now-famous word—not mere absence of anger, but a positive and royal virtue:
“It is on this eighth step that the crown of gentleness is found. […] Gentleness is a constant immobility of our soul, which makes us neither agitated by honors nor troubled by humiliations; it is like a majestic rock in the midst of a stormy sea, and the foaming waves come to break and die against its unshakable flanks.” — Saint John Climacus, The Ladder of Divine Ascent, steps 8 and 24[17]
Gentleness is therefore not softness: it is the stability of a soul unshaken by anything, the exact opposite of fragile anger. One earns it, Climacus specifies, “by laborious effort”—one who is gentle by temperament has not yet won the crown; it is gained by one who has conquered anger step by step[18].
The Legislators of Peace: Saint Benedict and Saint Augustine
Saint Benedict: “Do Not Satisfy Your Anger”
What the Desert Fathers had observed, Saint Benedict (c. 480–547) made into a law of life for all the West. In chapter 4 of his Rule, among the “tools of good works,” he engraves two brief precepts that summarize the entire struggle—prohibiting the act of anger and making peace before nightfall:
“Do not satisfy your anger. Do not reserve time to exercise your vengeance. […] Restore peace before sunset with the one from whom discord separates you.” — Saint Benedict, Rule, ch. 4[19]
Benedict does not ask that one not feel the movement of anger—that is beyond the will—but that one not “satisfy” it, not give it an act, and cut short rancor by making peace the same day. The precept repeats verbatim “do not let the sun go down on your anger” (Eph 4:26), embedding it in the daily fabric of communal life.
Saint Augustine: From the Speck to the Beam, from Anger to Hatred
Saint Augustine (354–430) gives, in his own Rule, the most penetrating analysis of the danger of anger: not its immediate violence, but its slow transformation into hatred if allowed to persist. The now-proverbial phrase plays on the Gospel image of the speck and the beam:
“Have no quarrels, or end them as soon as possible, lest anger grow into hatred, make a speck into a beam, and turn the soul into a murderer.” — Saint Augustine, Rule, ch. 6[20]
Augustine condenses here a whole psychology of sin: a twig of irritation, neglected, becomes the beam that blinds the heart, and nurtured anger becomes hatred—which, according to Saint John, already makes us murderers: “Whoever hates his brother is a murderer” (1 John 3:15)[21]. Hence the urgency: not so much to suppress the spark as to extinguish it immediately, before it ignites.
Saint Thomas Aquinas: Good Anger and Bad Anger
In the 13th century, Saint Thomas Aquinas (1225–1274) brought a decisive distinction to the debate by dedicating the entire question 158 of the Secunda Secundae to anger. Against an indiscriminate condemnation, he reminds us that the movement of anger, regulated by reason, can be good — it is even the instrument of zeal for justice:
“If one becomes angry according to right reason, anger is praiseworthy. […] The absence of anger where one ought to be angry is a vice, because it implies that the will does not rise up against evil.”
— Saint Thomas Aquinas, Summa Theologica, IIa-IIae, q. 158, a. 1[22]
Thomas supports this strong thesis with a blunt statement from Saint John Chrysostom, which he adopts and which corrects all false gentleness:
“He who does not become angry when he has reason to do so sins; for unreasonable patience sows vices, nourishes negligence, and invites evil not only from the wicked but also from the good.”
— Saint John Chrysostom, quoted by Saint Thomas Aquinas, Summa Theologica, IIa-IIae, q. 158, a. 1[23]
But Thomas does not let the struggle rest: he immediately shows how this good anger degenerates into vice. It sins by its object (becoming angry without cause, or more than is necessary), by its manner, or by its duration. And he ranks anger among the capital vices, because it generates a whole progeny — quarrels, indignation, blasphemy, resentment — following Saint Gregory the Great[24]. His doctrine thus sets the measure that the entire tradition sought: the goal is not insensitivity, but anger entirely subject to reason and charity, which ignites in the service of good and extinguishes as soon as justice is done.
Saint Francis de Sales: Gentleness, Queen of the Virtues
A Fiery Temper, Overcome
No saint has spoken of anger with more authority than Saint Francis de Sales (1567–1622), bishop of Geneva and doctor of the Church — because none had a more difficult temper to tame. His biographers, starting with his friend Jean-Pierre Camus, report that he was naturally bilious and quick-tempered, and that it took him more than twenty years of work to become the model of gentleness that posterity remembers[25]. His gentleness is therefore not an inherited temperament, but a virtue won — which makes it imitable by all.
“You Catch More Flies with Honey than with Vinegar”
In the Introduction to the Devout Life, Francis de Sales makes gentleness the great weapon against anger. The maxim that has become proverbial — you catch more flies with a spoonful of honey than with a hundred barrels of vinegar — appears in none of his works: it is a saying his first biographer reports as advice addressed to his friend Camus, and which the entire Salesian tradition attributes to him[26].
Correction of others, he writes, gains everything by being done gently: angry firmness closes hearts, meekness opens them. This is, transposed into ordinary life, the lesson of Cassian and Climacus — one corrects well only when disarmed of anger.
The Subtle Trick: Anger Against Oneself
Francis de Sales’s keenest observation concerns a kind of anger that other masters rarely mention: the anger one turns against oneself after a fault, which is nothing but disappointed pride:
“How greatly at fault are those who, having become angry, grow angry at having grown angry […] ; for by this means they keep their heart steeped and soaked in anger […] ; besides, this anger, vexation, and bitterness against oneself tends toward pride and has no origin but self-love, which is troubled and anxious at seeing us imperfect.” — Saint Francis de Sales, Introduction to the Devout Life, Part III, ch. 9 (original 1619 text)[27]
In today’s language: those who grow angry at having become angry keep their heart soaked in anger. The remedy is to correct oneself as a father corrects his child — “with gentle and calm admonitions, having more compassion for him than passion against him”[28]. Here, Francis de Sales joins and extends the tradition: the gentleness owed to others is also owed to oneself.
Other Voices: Ambrose, Francis of Assisi, Catherine of Siena
The chorus is not limited to the great treatises. Several saints have left, in just a few lines, words that the memory of the Church has preserved.
Saint Ambrose: Recovering the Innocence of Children
Saint Ambrose (c. 340–397), bishop of Milan, devotes a passage of his Treatise on Duties to anger, where he proposes an unexpected model—the promptness of children to reconcile:
“Children quickly get angry with one another, but they calm down easily and run to make peace with greater gentleness; they do not know how to treat each other with cunning and artifice. Therefore, prepare yourself, as if you were a child, not to hold a grudge over an insult.” — Saint Ambrose, Treatise on Duties, Book I[29]
The evil of adult anger is not so much the outburst as the resentment that settles in and calculates. The child, on the other hand, forgets the offense immediately: Ambrose makes this the image of the reconciled soul.
Saint Francis of Assisi: Never Losing the Peace of the Soul
Saint Francis of Assisi (1182–1226), in his Admonitions, pushes the demand to its limit: even in the face of the sin of another—the only evil that truly deserves a reaction—the servant of God must never allow himself to be disturbed, because judgment belongs to God alone:
“No matter how great the sin committed, the servant of God may be affected in his love for the offended God, but he must never lose the peace of his soul nor become angry; by doing so, he would unjustly claim a right that belongs only to God: to judge a fault.” — Saint Francis of Assisi, Admonitions, 11[30]
Saint Catherine of Siena: The Neighbor, Occasion for All Virtues
Saint Catherine of Siena (1347–1380), Doctor of the Church, hears in her Dialogues the Eternal Father reveal to her the hidden meaning of trial: it is precisely the angry person who gives the soul the opportunity to exercise gentleness, just as the unjust give the opportunity to exercise justice:
“It is through the neighbor that one practices the virtues, especially patience, when one receives insults. The soul exercises its humility with the proud, its faith with the unbeliever, its gentleness with the angry one. The neighbor is the occasion for all virtues.” — The Eternal Father to Saint Catherine of Siena, The Book of Dialogues[31]
The reversal is complete: the one who makes us angry is no longer an obstacle but the occasion offered to grow in gentleness.
Modern Voices: Mastering One’s Character
Saint Josemaría Escrivá: “Wait Until Tomorrow”
In the 20th century, Saint Josemaría Escrivá (1902–1975) translates ancient wisdom into brief, concrete advice in The Way. He first appeals to common sense—the anger is useless:
“Why get angry if your anger offends God, annoys your neighbor, makes you have a bad time… and if, in the end, you still have to calm down?” — Saint Josemaría Escrivá, The Way, no. 8[32]
Then he gives the golden rule of correction—delay, until indignation subsides:
“Do not reprimand in the heat of indignation. Wait until tomorrow, or even longer. Then, once you are calm and your intention purified, do not fail in your duty to correct. You will achieve more with a word of affection than in three hours of argument. Master your character.” — Saint Josemaría Escrivá, The Way, no. 10[33]
Pope Francis (2013–2025): Anger and “Holy Indignation”
A sign of the ongoing relevance of the struggle, Pope Francis devoted an entire catechesis to it during the general audience of January 31, 2024, in his cycle on vices and virtues. He first describes its destructive power:
“Anger is a vice that destroys human relationships. It expresses the inability to accept the diversity of the other… When the relationship reaches this level of degeneration, lucidity is lost. Anger causes one to lose lucidity.” — Pope Francis, General Audience, January 31, 2024[34]
Taking up Saint Paul, he makes immediate reconciliation the only remedy and names the virtues that disarm anger:
“Do not let the sun go down on your anger (Eph 4:26). It is important that everything be resolved immediately… What can counter anger is kindness, openness of heart, gentleness, patience.” — Pope Francis, General Audience, January 31, 2024[35]
But, as a faithful doctor, the pope also reminds us—as Thomas and Chrysostom did—that not all anger is bad, and that a certain indignation before injustice is even a sign of a living soul:
“If a person never gets angry, if they are not indignant at injustice, if they do not feel a shudder at the oppression of the weak, it would mean that they are not human, and even less Christian. Holy indignation exists… Jesus knew it. But we must distinguish well: one thing is zeal, holy indignation; another is anger, which is bad.” — Pope Francis, General Audience, January 31, 2024[36]
Sixteen centuries after the Desert Fathers, Pope Francis (2013–2025) repeats the same message: uproot the vice of anger that blinds and divides, keep the zeal that loves justice, and resolve everything “before the sun goes down.”
Echo: Gentleness in the Divine Will
Echoing the chorus of the saints, the spirituality of the Divine Will, transmitted to the servant of God Luisa Piccarreta (1865–1947), sheds light on the ultimate root of anger: living by one’s own will, which rebels as soon as it is opposed. “The human will, by opposing itself to the Divine, shatters its happiness,” Jesus tells Luisa; and to the soul that remains light and warmth in union with Him, He promises: “you will possess divine gentleness. You will no longer have bitterness or anger in your heart”[37]. From the very first pages of the Book of Heaven, Jesus thus teaches Luisa that gentleness is not a weakness, but a power capable of transforming even evil itself:
“My daughter, gentleness can change the nature of things. It can make bitterness sweet. So, be gentler!”
— Jesus to Luisa Piccarreta, The Book of Heaven, Volume 2, May 23, 1899[38]
In the teaching of the Divine Will, the soul that surrenders its will to the Divine Will enters into the peace of God, where there is no longer any clash or claim, because it no longer defends its self but accepts everything from the Father’s hand. There, anger loses its root: one no longer becomes irritated by what opposes a personal will that has been surrendered to God. The gentleness of Christ, “meek and humble of heart”—the goal of all the saints’ struggle—becomes the soul’s permanent climate.
A Formula from Each Master: The Common Grammar of the Battle
Placed side by side, the great sayings of the saints form a true grammar of the battle against anger. Each sheds light on the same truth from a different angle.
| Master | Formula / Image | What It Teaches |
|---|---|---|
| Evagrius Ponticus | “Whoever prays while holding a grudge sows in the sea” | Anger and resentment make prayer impossible |
| Saint John Cassian | “Uproot the poisoned root” | Anger is not to be moderated: it must be uprooted, even if “just” |
| Saint John Cassian | The beam “of gold or lead” | All anger blinds, even when adorned with good reasons |
| Saint John Climacus | The genealogy: daughter of pride, mother of hatred | Anger arises from pride and its enemy is humility |
| Saint Benedict | “Do not satisfy your anger” | Do not act on the impulse; make peace before nightfall |
| Saint Augustine | “Do not make a beam out of a straw” | Neglected anger becomes hatred, and hatred, murder |
| Saint Thomas Aquinas | Anger “according to right reason” | Anger governed by reason serves justice; its absence can be a vice |
| Saint Francis de Sales | “Honey rather than vinegar” | Gentleness won conquers better than anger |
| Saint Catherine of Siena | “Neighbor, occasion of all virtues” | The one who irritates me offers the chance to practice gentleness |
| Pope Francis (2013–2025) | “Zeal is not anger” | Distinguish holy indignation from sinful anger |
These formulas never contradict each other: they complement one another. Cassian speaks of the seriousness and urgency of uprooting; Climacus points to the root (pride) and the goal (the crown of gentleness); Benedict and Augustine speak of prevention (making peace before nightfall); Thomas speaks of measure (anger subject to reason); Francis de Sales speaks of manner (honey). All point toward the same victory: a soul sufficiently master of itself to love justice without losing peace.
What the Saints Do Not Say: Two Confusions to Avoid
The voice of the saints also corrects two misunderstandings. The anger they fight is neither the simple movement of the soul nor a call to softness.
Passionate Anger Is Not the Sin of Anger
When the Catechism and the saints condemn anger, they mean consented anger, willed resentment, the desire for revenge—not the first involuntary movement that arises before an offense. Saint Thomas emphasizes this, and Pope Francis reiterates: “We are not responsible for the appearance of anger, but always for its development.”[39] The passion that arises is not a sin; sin begins when the will adopts it, nourishes it, and translates it into actions. For these distinctions and details on remedies, see How to Grow in the Battle Against Anger.
Gentleness Is Not Softness or Cowardice
Conversely, the saints never preach indifference. The gentleness of Climacus is a “rock,” not a lack of strength; the zeal of Thomas and the “holy indignation” of Pope Francis are duties, not faults. Christ himself, “meek and humble of heart,” drove out the merchants from the Temple, “not in anger, but in zeal for the house of the Lord.”[40] The battle against anger therefore does not aim to extinguish all ardor before evil, but to purify that ardor of all self-love, so that it serves justice and not pride. True gentleness is the mastery of strength, not its absence.
The unanimous fruit: gentleness, strength, and peace
Regarding the fruit of victory, the saints are as unanimous as they are about the nature of evil. Conquered anger does not leave the soul impoverished: it makes it free, clear-sighted, and strong. Climacus calls it the “crown of gentleness”; Cassian sees in it the return of “clarity of discernment” and “true contemplation”[41]; Francis de Sales makes it the secret of all fruitful apostolate. From Gethsemane to the Egyptian desert, from the Rule of Benedict to the 2024 Roman catechesis, the message of the saints is one: holiness is not the impassibility of cold hearts, but a gentleness won at the price of struggle—a strength that loves without burning and corrects without disturbance, in the image of Christ “gentle and humble of heart.” To move from listening to the saints to practicing the struggle, read How to Grow in the Battle Against Anger.

Notes and References
John Cassian (c. 360–435), Institutes of the Coenobia, book VIII “On the Spirit of Anger”, ch. 1, trans. E. Cartier (verified full text); reference edition: SC no. 109, Cerf: “Anger is the fourth vice we must fight, and from which we must uproot the poisoned root from our souls. As long as this passion rules our heart, and darkens our inner sight with its thick shadows, we cannot acquire clarity of discernment nor reach true contemplation.” Cassian then cites James 1:20 and several Proverbs (“anger even loses the prudent”).
1 10 41Pope Francis, Catechesis on Vices and Virtues — 6. Anger, General Audience of January 31, 2024, full text on vatican.va. The pope describes anger as “a vice destructive of human relationships” that “makes one lose clarity”; he cites Eph 4:26 (“do not let the sun go down on your anger”) and names the remedies: “kindness, openness of heart, gentleness, patience.” But he distinguishes vice-anger from “holy indignation”: “If a person never gets angry, if they are not indignant at injustice… that would mean they are not human, much less Christian.” He finally reminds us: “We are not responsible for the arising of anger, but always for its development,” and that Jesus knew zeal, “not out of anger, but out of zeal for the house of the Lord” (cf. Mk 3:5; Mt 21:12-13).
2 34 35 36 39 40Testimony of the Salesian biographical tradition, whose first witness is Jean-Pierre Camus (1584–1652), bishop of Belley, friend and confidant of Saint Francis de Sales (1567–1622): an ardent and quick-tempered nature, tamed by an effort of more than twenty years that made him a model of gentleness (cf. J.-P. Camus, The Spirit of Saint Francis de Sales). As the precise rejoinders attributed to the saint on this subject could not be re-verified word for word from the source, none is quoted here in quotation marks. Salesian gentleness is therefore presented as a virtue conquered, not a natural gift — which makes it exemplary for choleric temperaments.
3 25Letter to the Ephesians 4:26-27, official liturgical translation (AELF, text from aelf.org): “If you are angry, do not fall into sin; do not let the sun go down on your anger. Give the devil no foothold.” The verse, which quotes Psalm 4:5, distinguishes the movement of anger (which may not be sin) from nurtured resentment (which “gives the devil a foothold”). This is the foundational text of all monastic doctrine on reconciliation before nightfall—explicitly taken up by Cassian (Inst. VIII, 9), Saint Benedict (Rule, ch. 4), and Pope Francis (January 31, 2024).
4Letter of Saint James 1:19-20, official liturgical translation (AELF, text from aelf.org): “Know this, my beloved brothers: everyone must be quick to listen, slow to speak, slow to anger, for man’s anger does not accomplish what is just in God’s eyes.” A key verse in this dossier: human anger, even when it believes itself just, by itself lacks God’s justice. Cassian explicitly cites it (Inst. VIII, 1).
5Gospel according to Saint Matthew 5:22, official liturgical translation (AELF): “But I say to you, everyone who is angry with his brother will be liable to judgment.” In the Sermon on the Mount, Christ internalizes the commandment “You shall not kill” down to anger of the heart, the root of murder—exactly the sequence Saint Augustine will reprise (anger → hatred → homicidal soul, cf. 1 John 3:15).
6Gospel according to Saint Matthew 11:29, official liturgical translation (AELF): “Take my yoke upon you, and learn from me, for I am gentle and humble in heart, and you will find rest for your souls.” The only passage where Christ describes himself; “gentle” (πραΰς, praüs) is the virtue opposed to anger. The entire struggle of the saints is ordered toward this gentleness of Christ as its model and goal.
7Evagrius Ponticus (c. 345–399), Practical Treatise (or The Monk), ch. 6–14, ed. A. and C. Guillaumont, Sources Chrétiennes no. 170–171, Cerf, 1971. Evagrius links all logismoi (thoughts) to eight generic thoughts: gluttony, fornication (lust), avarice, sadness, anger (ὀργή), acedia, vainglory, pride. Anger is analyzed as one of the most violent; it is from this list, transmitted by Cassian, that the seven capital sins of the Latin tradition will derive.
8Evagrius Ponticus, Chapters on Prayer (Περὶ προσευχῆς), ch. 21–22 and 24, transmitted under the name of Saint Nil in the Philokalia; critical edition SC no. 589, Cerf. Evagrius teaches there that true prayer is impossible for one who harbors resentment: “If you desire to pray properly, grieve no soul… The resentment of injuries (μνησικακία) makes the intellect wild, and one who prays while holding a grudge is like one who sows into the sea.” For Evagrius, anger, and especially the resentment that prolongs it, is the primary obstacle to prayer.
9John Cassian, Institutes of the Coenobia, VIII, 5 (“A religious must always be calm”), trans. E. Cartier: commenting on Ephesians 4:31 (“Put away all anger from you”), Cassian rejects the exception of “useful and necessary” anger: “He does not except even that which seems useful and necessary to us. If one must rebuke a guilty brother, let it be done with moderation, lest in trying to cure someone of a slight fever, one falls into a worse illness through the blindness of anger.”
11John Cassian, Institutes of the Coenobia, VIII, 6 (“Danger of anger, whether its cause is just or unjust”), trans. E. Cartier: “Whatever the cause of anger, this violent passion blinds the eyes of the heart, and places, through the evil it produces there, like a beam that prevents it from seeing the sun of justice. Whether this obstacle is gold, lead, or some other metal, the sight always suffers, and the richness of the metal makes no difference in the blindness.” The image (a golden beam blinds as much as a lead beam) means that even a “noble” or “justified” anger clouds judgment.
12John Cassian, Institutes of the Coenobia, VIII, 7 (“In what way anger can be useful”), trans. E. Cartier: Cassian reserves only one legitimate use of anger—to turn it against our own vices and against anger itself: “We can be angry at the anger we have had toward our brother; this is the way to resist its bad counsel… ‘Be angry and do not sin,’ said the Prophet (Ps 4:5).”
13John Cassian, Institutes of the Coenobia, VIII, 9–10, trans. E. Cartier: at the end of ch. 9 and in ch. 10, commenting on “do not let the sun go down on your anger” (Eph 4:26), Cassian warns that letting anger last overnight is to allow it to “set its traps deep in our souls”; he allegorically reads this “sun” as Christ, the “Sun of Justice” (cf. Mal 4:2), who must not set in a heart darkened by anger. Reconciliation before nightfall thus becomes the practical rule for the monk.
14Saint John Climacus (c. 579–649), The Ladder of Divine Ascent (Ladder of Paradise), step 8 “On Non-Anger and Gentleness”, full verified text (edition foi-orthodoxe.fr). Climacus questions anger personified, which replies: “The first who contributes to my existence is pride. I also have several mothers: vainglory, greed, intemperance, lust. My daughters are the thought of insults, hatred, quarrels, and enmities… But the virtue that constantly sets traps for me and harms me the most is humility.” Quotation condensed for readability; meaning and terms faithful to the text.
15Saint John Climacus, The Ladder of Divine Ascent, step 8: “Three monks one day received the same insult. One felt stung but endured it in silence; another rejoiced inwardly but was inwardly grieved out of charity for the one who had wronged him; the third completely forgot himself to care only for his brother, weeping hot tears over his fault. Thus, in these three were seen three virtues: the fear of God, hope, and love.” The parable grades the victory over anger, from simple silence to perfect charity.
16Saint John Climacus, The Ladder of Divine Ascent, steps 8 and 24, full verified text: “It is on this eighth step that the crown of gentleness is found… He who, by the temperament of his nature, is of a gentle disposition might not deserve it; but he deserves it who, by laborious effort, has won the victory over anger.” And at step 24: “Gentleness is a constant immobility of our soul, which makes us neither agitated by honors nor disturbed by humiliations… it is like a majestic rock in the midst of a stormy sea.” Gentleness is therefore not an innate temperament but a virtue conquered.
17 18Saint Benedict of Nursia (c. 480–547), Rule, ch. 4 “The Instruments of Good Works”, nos. 22, 23, and 73 (numbering of instruments), standard French translation (Solesmes): “Iram non perficere” — “Do not satisfy your anger”; “Iracundiae tempus non reservare” — “Do not reserve time to exercise your vengeance”; “Et cum discordante ante solis occasum in pacem redire” — “Restore peace before sunset with the one with whom you are at discord” (cf. Eph 4:26). Benedict forbids the act of anger and imposes reconciliation the same day.
19Saint Augustine (354–430), Regula ad servos Dei (Rule), ch. 6: “Lites aut nullas habeatis, aut quam celerrime finiatis, ne ira crescat in odium, et trabem faciat de festuca, et animam faciat homicidam” — “Have no quarrels, or end them as quickly as possible, lest anger grow into hatred, make a beam out of a straw, and make the soul a murderer.” The image (straw/beam) comes from Mt 7:3–5; the conclusion (“murderer”) cites 1 Jn 3:15: “Whoever hates his brother is a murderer.” Foundational text for Augustinian communal life (canons regular, Dominicans, etc.).
20 21Saint Thomas Aquinas (1225–1274), Summa Theologica, IIa-IIae, q. 158 (On Anger), a. 1: anger, as a passion or movement of the irascible appetite, “is not evil by nature”; everything depends on its conformity to reason. “If one is angry according to right reason, anger is praiseworthy” (ira per zelum); on the contrary, “the lack of anger where one ought to be angry is a vice”, because it shows a will that does not oppose evil. Leonine edition; French translation Revue des Jeunes, Cerf.
22Saint John Chrysostom (c. 349–407), Homilies on Saint Matthew, hom. 11, cited by Saint Thomas Aquinas, Summa Theologica, IIa-IIae, q. 158, a. 1, arg. 3 (and repeated in the body of the article): “He who does not get angry when he has reason to, sins; for unreasonable patience sows vices, nourishes negligence, and invites evil not only from the wicked but also from the good.” This statement serves Thomas to establish that a total absence of anger before injustice is not a virtue but a fault.
23Saint Thomas Aquinas, Summa Theologica, IIa-IIae, q. 158, a. 6–7: anger is a capital vice when the desire for vengeance outweighs reason; following Saint Gregory the Great (Moralia in Job, XXXI, 45), Thomas lists its “daughters” — quarrels (rixae), swelling of the spirit (tumor mentis), insults (contumeliae), shouts (clamor), indignation (indignatio), and blasphemy (blasphemia). Anger sins by its cause (being angry without reason), by its measure (more than necessary), or by its duration (resentment that does not relent).
24Maxim attributed to Saint Francis de Sales by the biographical tradition: Louis de la Rivière, Life of Saint Francis de Sales (1624), p. 584, reports it as a saying addressed to Jean-Pierre Camus — in substance: always be as gentle as possible, for you catch more flies with a spoonful of honey than with a hundred barrels of vinegar (concordant reference and content in the Oxford Dictionary of Proverbs and Salesian repertoires; the 1624 page could not be collated from the source in session, so the maxim is not cited here as a word-for-word verified text). It is in any case consistent with his doctrine of gentleness (cf. Introduction to the Devout Life, Part III, ch. 8, “On Gentleness Toward Others and Remedy Against Anger,” which does not contain this formula): gentleness opens hearts where anger closes them — the law of all fraternal correction and all apostolate.
26Saint Francis de Sales, Introduction to the Devout Life, Part III, ch. 9 “On Gentleness Toward Ourselves,” original 1619 text (Jacques Boulenger ed., 1909, established from the 1619 edition; Wikisource transcription): “How greatly at fault are many who, having become angry, grow angry at having grown angry […] ; for by this means they keep their heart steeped and soaked in anger […] ; besides, this anger, vexation, and bitterness against oneself tends toward pride and has no origin but self-love, which is troubled and anxious at seeing us imperfect.” In modern language: “to grow angry at having grown angry” is to be angry at oneself for having become angry; a heart “steeped and soaked” in anger is a heart that remains soaked in it.
27Saint Francis de Sales, Introduction to the Devout Life, Part III, ch. 9, original 1619 text (Jacques Boulenger ed., 1909, from the 1619 edition; Wikisource transcription): “Believe me, Philothea: just as a father’s admonitions, made gently and cordially, have much more power over a child to correct him than anger and wrath; so, when our heart has committed some fault, if we reprove it with gentle and calm admonitions, having more compassion for it than passion against it […]” — that is, in modern language: reprove one’s heart gently and calmly, out of compassion rather than passion against oneself. The gentleness owed to others must also be owed to oneself.
28Saint Ambrose (c. 340–397), bishop of Milan, Treatise on Duties (De officiis ministrorum), book I, on anger: “Children quickly get angry with one another, but they calm down easily and run to reconcile with more gentleness; they do not know how to treat each other with cunning and craft. Therefore, prepare yourself, as if you were a child, not to hold grudges for insults, not to use malice, and to make all things on your part proceed from innocence.” Ambrose contrasts the calculating grudge of the adult with the immediate reconciliation of the child (cf. Mt 18:3).
29Saint Francis of Assisi (1182-1226), Admonitions, 11, 1-3: “A servant of God must feel no repulsion for anything except sin. And even in that case, no matter how great the sin committed, the servant of God may be affected in his love for the offended God, but he must never lose the peace of his soul nor become angry; by doing so, he would unjustly claim a right that belongs only to God: to judge a fault.” Anger, even in the face of sin, usurps the judgment that belongs to God alone.
30Saint Catherine of Siena (1347-1380), Doctor of the Church, The Book of Dialogues (Dialogue of Divine Providence), Treatise on Discretion: the Eternal Father teaches that virtues are exercised through one’s neighbor: “It is through the neighbor that one practices virtues, especially patience, when receiving insults. The soul exercises its humility with the proud, its faith with the unbeliever, its hope with the despairing, its justice with the unjust, its kindness with the wicked, its gentleness with the angry. The neighbor is the occasion for all virtues.” The one who irritates us thus becomes the opportunity offered to exercise gentleness.
31Saint Josemaría Escrivá de Balaguer (1902-1975), The Way (Camino, 1939), no. 8: “Why get angry, if your anger offends God, annoys your neighbor, makes you have a bad time… and if, in the end, you still have to calm down?” The argument of common sense: anger is as useless as it is harmful.
32Saint Josemaría Escrivá, The Way, no. 10: “Do not reprimand in the heat of indignation over the fault committed. Wait until the next day, or even longer. Then, once you are calm and your intention purified, do not fail in your duty to correct. You will achieve more with a word of affection than in three hours of argument. Master your character.” The golden rule of correction: delay until indignation subsides, without giving up on correction.
33Jesus to Luisa Piccarreta, The Book of Heaven, Volume 20, November 1, 1926 (“What the Supreme Fiat Does in Every Created Thing”): in Luisa’s round through Creation, Jesus reports to her what His Will, veiled in the sun, says to man — “The human will, by opposing itself to the Divine, shatters its happiness” — and the promise made to the soul that remains light and warmth in union with Him: “You too, by always being light and warmth, will possess divine gentleness. You will no longer have bitterness or anger in your heart.” (text verified on 2026-10-04 against the Library copy, The Book of Heaven – 36 volumes).
37Luisa Piccarreta (1865–1947), The Book of Heaven, Volume 2, May 23, 1899 (“Fruits of Gentleness and Detachment”): “My daughter, gentleness can change the nature of things. It can make bitterness sweet. So, be gentler!” (French trans. Guy Harvey, Lumen Luminis ed., private use, p. 39–40; text re-confirmed on 2026-10-04 against the Library copy Volume 2.pdf: date, title, and words of Jesus verified word for word). The spirituality of the Divine Will presents gentleness not as weakness but as a transforming power.
