Chastity is undoubtedly, of all Christian virtues, the one that today causes the most misunderstandings and mistrust. The word itself has become suspect: in the mouth of contemporary culture, “chaste” is almost synonymous with “uptight,” “frustrated,” “repressed” — as if proposing chastity were proposing a mutilation. It is imagined sometimes as simple abstinence, sometimes as pathological repression, sometimes as contempt for the body inherited from some unknown puritanism, sometimes as a morality of prohibitions that the Church imposes on bodies to better control consciences. Rarely has a virtue been so thoroughly covered with counterfeits.
Yet these caricatures not only miss the mark: they invert it. Far from being a denial of sexuality, chastity is, according to the Catechism, “the successful integration” of sexuality into the person — the condition for love to be true, a total gift, and the body inhabited as “a temple of the Holy Spirit”[1][2]. Like every virtue, it walks a narrow path between two abysses: by deficiency, impurity and lust, which isolate pleasure and enslave; by excess, contempt for the body and anxious rigorism, which condemn as shameful what God created good. True chastity is neither: it is freedom, clarity, a capacity to love.
This article reviews the most frequent misunderstandings about chastity. For each, it states the error in its common formulation, shows why it is appealing, why it is false, then recalls what the Church really teaches. This is neither a collection nor a practical guide: for the saints’ own voice, see What the Saints Say About Chastity; for the concrete path of growth, see How to Grow in Chastity. Here, as in the twin articles Common Misconceptions About Faith and Common Misconceptions About Temperance, we clear the ground: first learning to recognize counterfeit coins in order to better receive the true gold.
Why Is Chastity So Often Misunderstood?
A Word That Has Become Suspect: “Chaste” as Synonymous with “Frustrated”
Few words have undergone such a reversal of meaning. In contemporary culture, “chaste” no longer evokes a virtue but a privation: one imagines someone who denies themselves, who restrains themselves, who misses out on life. Chastity is placed on the side of “no,” prohibition, sadness — in short, on the side of everything that prevents enjoyment. To this reduction is added suspicion: what if this austerity is only a façade, covering repression or even hypocrisy?
The error is appealing because it rests on a correct intuition — chastity indeed involves self-mastery, therefore a certain renunciation — but it immediately distorts it by seeing only mutilation. But mastering is not mutilating. The musician who disciplines his fingers does not mutilate his music: he makes it possible. Likewise, the Catechism says chastity “involves learning self-mastery, which is a pedagogy of human freedom”[3]. It is not on the side of “no” but on the side of “yes”: yes to true love, yes to total gift, yes to freedom regained over passions.
The Sexual Revolution and the Myth of “Liberation”
The deepest modern misunderstanding comes from a narrative that has become almost a cultural dogma: that of “sexual liberation.” According to this narrative, humanity long groaned under the weight of a repressive morality until modernity finally freed it from shame, taboos, and guilt. Within this framework, chastity is not only outdated: it is the enemy to be defeated, the last vestige of an old order founded on fear of the body.
But this “liberation” has a presupposition that must be named: it equates freedom with the absence of any limit. Yet, Vatican II observes, man’s true dignity is the opposite: he attains it “when, freeing himself from all slavery to passions, by the free choice of good, he moves toward his destiny”[4]. The Catechism decisively settles what culture calls permissiveness:
“What is called permissiveness in morals is based on an erroneous conception of human freedom; for its own building up, freedom needs to be educated beforehand by the moral law.”
— Catechism of the Catholic Church, § 2526[5]
In other words, what is presented as liberation is often a new enslavement: no longer to an external rule, but to inner impulses no longer controlled. Chastity, on the other hand, does not free one from sexuality — it frees sexuality, restoring its meaning.
Reminder: What Chastity Really Is
Before correcting errors, one needs a compass. The Catechism gives the reference definition, each word of which dispels a misunderstanding:
“Chastity means the successful integration of sexuality within the person and thus the inner unity of man in his bodily and spiritual being. Sexuality […] becomes personal and truly human when it is integrated into the relationship of person to person, in the total and temporal mutual self-gift of man and woman.”
— Catechism of the Catholic Church, § 2337[6]
Three decisive traits follow. First, chastity is an integration, not an amputation: it does not remove sexuality, it unifies it with the whole person, body and soul. Second, it is ordered to gift: “the virtue of chastity involves […] the integrity of the person and the integrality of the gift”[7]. Finally, it is both virtue and grace: “Chastity is a moral virtue. It is also a gift of God, a grace, a fruit of spiritual effort”[8]. Remove any one of these three traits, and you have a counterfeit. Saint Paul sums it up in one stroke, rooting it not in fear but in the holiness of God:
“God’s will is that you live in holiness, abstaining from debauchery, and that each of you control your own body in a way that is holy and honorable, not in passionate lust like the pagans who do not know God.”
— 1 Thessalonians 4:3-5[9]
Common Errors About the Nature of Chastity
Error — “Chastity is abstinence, not having sexual relations”
This is the most widespread and persistent misunderstanding. People confuse chastity (a virtue proper to all) with continence (the abstention from sexual acts, proper to certain states of life). In this confusion, “being chaste” would mean “not making love”—so that a husband who unites with his wife would, by definition, not be chaste. This error is appealing because it is simple: it reduces an interior virtue to a behavioral statistic.
But the Church teaches exactly the opposite. “Every baptized person is called to chastity,” including spouses: “Married persons are called to live conjugal chastity”[10][11]. Chastity is therefore not measured by abstinence, but by the truth of the gift: the union of spouses who give themselves to each other in fidelity and openness to life is chaste; it is not chaste when pleasure is sought “for itself, isolated from the purposes of procreation and union”[12]. Abstinence is only one form of chastity, that of the single, the engaged, and the consecrated; it is not its definition.
“There are three forms of the virtue of chastity: that of the married, that of widowhood, and that of virginity. We do not praise one to the exclusion of the others.”
— Saint Ambrose, De viduis, cited in the Catechism § 2349[13]
Error — “Chastity is repressing and suppressing one’s sexuality”
Here is the objection inherited from certain popular psychology: chastity would be nothing but repression—one buries one’s impulses, denies them, and they resurface sooner or later as neurosis or hypocrisy. This error is appealing because it wears the authority of the human sciences and because there is a real counterfeit of chastity that truly represses.
But repression and integration are two opposite acts. Repression is pushing into the shadows a reality one refuses to face; integration is welcoming it and giving it its proper place in a unified life. Chastity belongs to the latter: it “maintains the integrity of the powers of life and love placed” in the person[14]. Far from fragmenting the human being, it recomposes him:
“Chastity recomposes us; it brings us back to that unity which we had lost by scattering ourselves.”
— Saint Augustine, Confessions, X, 29, cited in the Catechism § 2340[15]
Repression divides; chastity unifies. Repression denies desire; chastity directs it. That is why the Catechism speaks of a “pedagogy of freedom” and not repression: its goal is not anxiety, but peace—“either man rules his passions and finds peace, or he lets himself be enslaved by them and becomes unhappy”[16].
Error — “Chastity is despising the body and pleasure”
Opposite to libertinism, another error often threatens sincere believers: making chastity a contempt for the body, as if the flesh were evil, pleasure suspicious, and sexuality a shameful concession. This is the Puritan, Manichean temptation: saving the soul by despising the body. This error is appealing because it seems more “spiritual,” more demanding—and because it mistakes the enemy.
Yet the Church has always condemned this contempt as a heresy, not a virtue. The body is good, sexuality is good, conjugal pleasure is “honest and worthy”: “The Creator himself […] established that in this function spouses experience pleasure and satisfaction of body and spirit. Therefore, spouses do nothing wrong in seeking this pleasure and enjoying it,” teaches Pius XII, cited by the Catechism[17]. Chastity does not attack pleasure but its disorder—pleasure separated from love and the person. Benedict XVI expressed this crucial nuance about eros:
“It is not the rejection of eros, not its ‘poisoning,’ but its healing in view of its true greatness.”
— Benedict XVI, Deus Caritas Est, no. 5[18]
Chastity does not extinguish desire: it heals it. It does not make the body an enemy but recognizes it for what it is—“a temple of the Holy Spirit,” “a manifestation of divine beauty”[19].
Error — “Chastity is a morality of prohibitions”
Many reduce chastity to a list of prohibitions: don’t do this, don’t look at that, don’t desire. The virtue would be entirely negative, a series of barriers raised against pleasure. This error is appealing because chastity indeed involves real and serious prohibitions—lust, pornography, fornication[20]—and it is easier to remember a list of “no’s” than a demanding “yes.”
But reducing chastity to its prohibitions is confusing the fence with the garden. Prohibitions protect a positive good; they are not that good itself. That good is the capacity to truly love. For self-mastery is not an end in itself: it is “ordered to the gift of self”[21]. Chastity is less a boundary than a school:
“Charity is the form of all the virtues. Under its influence, chastity appears as a school of self-giving. […] Chastity leads the one who practices it to become a witness to the fidelity and tenderness of God before others.”
— Catechism of the Catholic Church, § 2346[22]
A morality of prohibitions says: “You shall not possess.” Chastity says: “You will learn to give.” It is not the same thing.
Errors Regarding the Scope of Chastity
Error — “Chastity only concerns priests, religious, and singles”
Chastity is often imagined as a specialty: the concern of consecrated persons who have taken a vow of continence, or singles awaiting marriage. Once married, one would be “dispensed” from it. This error is appealing because it again confuses chastity with continence: if chastity were only abstinence, it would obviously only concern those who abstain.
But the Catechism is clear: “All the faithful of Christ are called to lead a chaste life according to their particular state of life”[23]. What changes according to the states is not chastity itself, but its form:
“Chastity must qualify persons according to their different states of life: some in virginity or consecrated celibacy […] others in the way determined for all by the moral law and according to whether they are married or single.” — CDF, declaration Persona humana, no. 11, cited in the Catechism § 2349[24]
Thus, engaged couples are called to chastity through continence, “reserving for the time of marriage the specific manifestations of conjugal love”[25]; and spouses to conjugal chastity, which requires fidelity, respect, and openness to life. No one is dispensed—because no one is dispensed from truly loving.
Error — “Spouses do not have to be chaste”
This is the corollary of the previous error and deserves separate treatment because it is so widespread. It is assumed that marriage is a kind of “license” that ends all demands: once spouses are united, everything is owed to them. This error is appealing because it seems to defend the couple’s freedom against an intrusive Church.
But it misunderstands what conjugal chastity is. It does not oppose any prohibition to the union of spouses; it protects its truth. It requires that the gift remain a “gift of the whole person”, and not the reduction of the other to an object of pleasure. Saint Paul already teaches this: one must “have mastery over one’s own body in holiness and honor, not in lustful passion”[26]. Conjugal chastity is what prevents the other from ceasing to be loved and becoming used even within marriage. It is the fidelity of the heart as much as of the body—because Jesus declares adulterous “whoever looks at a woman with lust”[27], and this applies also within the couple.
Error — “Chastity only concerns acts, not the gaze or thoughts”
One last error restricts chastity to only external acts: as long as one does nothing, one would be chaste, no matter what one looks at, desires, or consumes in imagination. This error is appealing in a culture saturated with images, where the gaze and fantasy seem harmless as long as they remain “in the head.”
But the Gospel places purity at the level of the heart:
“Blessed are the pure in heart, for they shall see God.” — Gospel according to Saint Matthew 5:8[28]
And Jesus adds: “Whoever looks at a woman with lust has already committed adultery with her in his heart”[29]. The battle for purity is therefore not only fought in actions, but “by purity of gaze, both external and internal; by discipline of feelings and imagination; by the refusal of any complacency in impure thoughts”[30]. This is why the Catechism classifies pornography among grave offenses against chastity, even though it does not involve any act with another: it “deforms the conjugal act” and makes each person “an object of base pleasure”[31]. Chastity is a virtue of the heart before it is a virtue of the hands.
Errors Regarding the Demand of Chastity
Error — “Chastity is impossible, against nature”
Here is the objection that discourages even trying: chastity would be an unrealistic ideal, contrary to human nature, reserved for a few heroes. Why aim for what cannot be achieved? This error is appealing because it relies on real experience of failure and because it offers a comfortable excuse: if it is impossible, one is dispensed from trying.
But it forgets two things. First, chastity is not a performance wrested from willpower alone: it is “a gift of God, a grace”[32]. Saint Augustine, who long believed he could conquer it by his own strength, made this decisive confession:
“I thought continence depended on my own strength, strength I did not know I had. And I was foolish enough not to know that no one can be continent unless you give it to him.” — Saint Augustine, Confessions, VI, 11, 20, cited in the Catechism § 2520[33]
Second, chastity is not “against nature” but conforms to the true nature of human love, which is only fully itself in total self-gift. What is “against nature” is rather the use that separates pleasure from love and from the person. Finally, chastity is not a state acquired all at once, but a growth: “Self-mastery is a long-term work. It is never considered as acquired once and for all”[34]—it “follows laws of growth marked by degrees of imperfection and too often by sin”[35]. Imperfection is not proof that it is impossible: it is the normal stage of a journey.
Error — “Sexuality is a need, like hunger, that must be satisfied”
This error has become a commonplace: sexuality would be a biological drive comparable to hunger or thirst, which would be unhealthy—or even dangerous—not to satisfy. Therefore, asking for chastity would be like asking to starve. This error is appealing because it reduces man to his physiology and because it gives a scientific veneer to complacency.
But the analogy is false. One does not die from sexual abstinence, whereas one dies from hunger; millions of people—consecrated persons, widows, singles, separated persons—live without sexual relations without ceasing to be fully human and fulfilled. Above all, human sexuality is never a mere reflex: it involves the person and their relationship to others. This is precisely what distinguishes man from animals, the Council reminds us:
“The dignity of the human person requires that he act according to a conscious and free choice, mature and determined by personal conviction and not under the sole effect of instinctive drives or external constraint.” — Second Vatican Council, Gaudium et Spes, no. 17[36]
Reducing sexuality to a “need” to be satisfied is precisely to renounce that dignity and to treat the other as a means to relieve tension. Chastity affirms the opposite: sexuality is not an appetite to satisfy, but a language of the person that only tells the truth in self-gift.
Error — “Chastity makes you frustrated, neurotic, unhappy”
This is the psychological objection, often decisive in contemporary imagination: chastity would be pathogenic. By “depriving” oneself, one would become bitter, tense, unhappy — frustration producing neurosis. The error is appealing because it confuses chastity with its repressed counterfeit, and because it assumes that happiness lies in the immediate satisfaction of desires.
Yet experience says otherwise. Misery more often arises from slavery to passions than from their mastery. The Catechism states it plainly: it is “by giving in to them” that man “becomes unhappy”, while he who “commands his passions obtains peace”[37]. Chastity is not sadness but inner freedom: it makes one available to love, capable of true friendship, freed from the tyranny of desire. That is why Saint Paul lists “self-control” among the fruits of the Spirit, alongside joy and peace:
“But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.” — Letter to the Galatians 5:22-23[38]
Chastity does not produce neurosis: it delivers from it, reconciling man with himself. Frustration comes from uncontrolled desire that never finds rest; peace comes from ordered desire that gives itself.
Error — “What matters is love and consent, not a rule”
The most current error is also the most seductive: as long as there is love and consent between adults, everything would be legitimate; chastity, with its “rules”, would be a moralistic intrusion into a purely private matter. The error is appealing because it invokes real values — love, respect for the other, freedom — and because it seems generous.
But it rests on an equivocation about the word “love”. Consent excludes violence; it does not guarantee the truth of love. One can consent to being reduced to an object; one can “love” without wanting the total good of the other, without commitment, without openness to life. Chastity does not oppose love: it is the measure of truth of love. It requires that the union express what it means — a gift “complete and without temporal limits”[39] — and not a revocable feeling. This is what John Paul II called the truth of the “language of the body”:
“Sexuality […] is truly human only if it is an integral part of the love in which man and woman commit themselves totally to one another until death.” — John Paul II, Familiaris Consortio, no. 11, cited in the Catechism § 2361[40]
As for the idea that chastity is a “strictly private” matter, it forgets that purity of morals involves the whole society: “Christian purity demands a purification of the social climate”[41]. The body is not a possession to be disposed of at will, but a gift: “You do not belong to yourselves, for you were bought at a price”[42].
Error and truth, at a glance
The following table summarizes the main misunderstandings reviewed and, for each, the corresponding Catholic teaching.
| Common Error | What the Church Really Teaches |
|---|---|
| Chastity is sexual abstinence | It is “the successful integration of sexuality within the person” (CCC § 2337); abstinence is only one form of it |
| Chastity is repressing one’s impulses | It is integrating and ordering them: it “recomposes” the person, it does not fragment them (St. Augustine) |
| Chastity despises the body and pleasure | The body and conjugal pleasure are good; chastity “heals” eros, it does not poison it (Benedict XVI) |
| Chastity is a morality of prohibitions | It is a “school of self-giving”, ordered to charity (CCC § 2346) |
| Only priests and celibates are concerned | “Every baptized person is called to chastity”, each according to their state (CCC § 2348) |
| Married couples do not have to be chaste | They are called to conjugal chastity: fidelity, respect, true giving (CCC § 2349) |
| Only actions count, not the gaze | Purity is first of the heart: “Blessed are the pure in heart” (Mt 5:8; 28) |
| Chastity is impossible, against nature | It is a gift from God and a gradual growth (CCC §§ 2342-2345) |
| Sexuality is a need, like hunger | It is a language of the person, not a reflex to satisfy (GS 17) |
| Chastity makes you frustrated and neurotic | It is freedom and peace, fruit of the Spirit (Gal 5:22-23; CCC § 2339) |
| Love and consent are enough | Chastity is the measure of truth of love: a complete, irrevocable gift (FC 11) |
Chastity, purity, continence, modesty: not to be confused
One last category of errors arises from the confusion of terms. Often, closely related but distinct realities are used as synonyms: chastity, purity of heart, continence, modesty, temperance. Distinguishing them is not a mere scholastic subtlety: it prevents reducing one to another.
Error — “To be chaste is to be pure”
Purity of heart is broader than chastity. The Catechism specifies that it concerns “primarily three areas: charity, chastity or sexual integrity, love of truth and orthodoxy of faith”[43]. Chastity is therefore one dimension of purity, the one that relates to sexuality; but one can be chaste and still have an impure heart in other ways — hard, deceitful, idolatrous. Conversely, purity of heart “is the prerequisite for the vision” of God and encompasses the entire rectitude of the soul[44]. To reduce purity solely to chastity is to diminish a vast promise: “Blessed are the pure in heart, for they shall see God.”
Error — “Chastity is continence”
As we have seen: continence is the abstention from sexual acts, proper to the unmarried, the engaged, and the consecrated[45][46]. Chastity, on the other hand, is the virtue that orders sexuality to love, in all states of life. Not every continent person is necessarily chaste (one can abstain out of disgust for the body, fear, or pride, which is not virtue), and not every chaste person is continent (spouses live chastity that is not abstinence). Continence is a way of living chastity; it is not identical to it.
Error — “Chastity, modesty, and temperance are the same thing”
Modesty is not chastity: it is its guardian and sign. “Purity demands modesty. This is an integral part of temperance […] it is ordered to chastity, of which it attests the delicacy”[47]. Modesty “protects the mystery of persons and their love”, guiding the gaze, clothing, and speech[48]. As for temperance, it is the broader cardinal virtue under which chastity is placed: “The virtue of chastity is placed under the movement of the cardinal virtue of temperance”, which “aims to imbue reason into passions and appetites”[49]. Chastity is therefore a part of temperance, applied to the sexual domain — just as sobriety is another part, applied to eating and drinking (see Common errors concerning temperance).
This last distinction also sheds light on why lust is so destructive: by disordering the strongest of appetites, it overflows into the whole life of the spirit. Saint Thomas, following Saint Gregory the Great, enumerates the “daughters of lust”: “blindness of the mind, thoughtlessness, inconstancy, haste, self-love, hatred of God, attachment to the present world, and horror or despair of the world to come”[50]. Chastity therefore does not only protect sexuality: it preserves the clarity of the entire soul.
Restoring chastity to its true beauty
At the end of this journey, an image emerges, opposite to the caricature. Chastity is neither deprivation, nor repression, nor contempt for the body, nor a morality of prohibitions reserved for a few. It is the successful integration of sexuality into the person — the condition for the body to be inhabited, desire to be ordered, and love to be true. It is entirely oriented toward gift: “self-mastery is ordered to self-gift”[51].
Three traits summarize what it truly is. First, it is a freedom: not the absence of limits, but victory over the slavery of passions, which makes man capable of possessing himself in order to give himself. Next, it is a clarity: the purity of heart that “already gives us the ability to see all things according to God” and opens us to the promised vision[52]. Finally, it is a capacity to love: for only he who does not reduce the other to an object can truly love him as a person.
Above all, chastity is not primarily a conquest, but a grace to be asked for. It is “a gift of God, a fruit of the spiritual work”, by which “the Holy Spirit gives the grace to imitate the purity of Christ to the one regenerated by the water of Baptism”[53]. This means that the last word does not belong to human effort, but to the Spirit who heals eros “toward its true greatness”[54]. Chastity takes nothing away: it restores dignity to the body, truth to desire, and depth to love.

Notes and References
Catechism of the Catholic Church, § 2337: “Chastity means the successful integration of sexuality within the person and thus the inner unity of man in his bodily and spiritual being. Sexuality, in which the belonging of man to the bodily and biological world is expressed, becomes personal and truly human when it is integrated into the relationship of person to person, in the mutual and total gift, temporally unlimited, of man and woman. The virtue of chastity therefore entails the integrity of the person and the integrality of the gift.”

You are not your own; you were bought at a price. Therefore glorify God in your body.”

25 46Gospel according to Saint Matthew 5:28, official liturgical translation (AELF): “But I say to you: everyone who looks at a woman with lust has already committed adultery with her in his heart.” Quoted in the Catechism § 2528.
27 29Gospel according to Saint Matthew 5:8, official liturgical translation (AELF): “Blessed are the pure in heart, for they shall see God.” Sixth Beatitude (Sermon on the Mount). Quoted in the Catechism § 2518.
28Catechism of the Catholic Church, § 2520: the baptized must struggle against the concupiscence of the flesh “by the virtue and gift of chastity, for chastity allows one to love with a right and undivided heart; by purity of intention […] ; by purity of gaze, both outward and inward; by discipline of feelings and imagination; by refusal of any complacency in impure thoughts that incline one to turn away from the path of divine commandments; […] by prayer.”
30Catechism of the Catholic Church, § 2354: “Pornography consists in removing sexual acts, real or simulated, from the intimacy of the partners to deliberately expose them to third parties. It offends chastity because it distorts the conjugal act, the intimate gift of spouses to each other. […] Each becomes for the other the object of a rudimentary pleasure and illicit profit.”
31Catechism of the Catholic Church, § 2520, citing Saint Augustine, Confessions, VI, 11, 20: “I believed that continence depended on my own strength, […] strength I did not know I had. And I was foolish enough not to know that no one can be continent unless you give it to him.”
33Catechism of the Catholic Church, § 2342: “Self-mastery is a long-term work. It is never considered acquired once and for all. It requires effort renewed at every age of life” (cf. Titus 2:1-6). The effort required may be more intense at certain times, especially during personality formation.
34Catechism of the Catholic Church, § 2343: “Chastity experiences laws of growth that pass through stages marked by imperfection and too often by sin.” The paragraph cites Familiaris Consortio, no. 9: “Day by day, the virtuous and chaste person builds himself up through numerous and free choices.”
35Letter to the Galatians 5:22-23, official liturgical translation (AELF): “But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. Against such things there is no law.” At vv. 19-21, Paul contrasts the “works of the flesh”: “immorality, impurity, licentiousness…” Quoted in the Catechism § 2345 (chastity, fruit of the Spirit).
38John Paul II, apostolic exhortation Familiaris Consortio, November 22, 1981, no. 11, cited in the Catechism § 2361: “Sexuality, by which man and woman give themselves to each other through the proper and exclusive acts of the spouses, is not something purely biological, but concerns the human person in what is most intimate. It is truly human only if it is an integral part of the love in which man and woman fully commit themselves to one another until death.”
40Catechism of the Catholic Church, § 2525: “Christian purity demands a purification of the social climate. It requires social means of communication to provide information attentive to respect and restraint. Purity of heart frees from diffuse eroticism and excludes spectacles that promote voyeurism and illusion.”
41Catechism of the Catholic Church, § 2518, citing Matthew 5:8: “The sixth beatitude proclaims: ‘Blessed are the pure in heart, for they shall see God.’ The ‘pure in heart’ are those who have aligned their intellect and will with the demands of God’s holiness, principally in three areas: charity, chastity or sexual rectitude, love of truth, and orthodoxy of faith.”
43Catechism of the Catholic Church, § 2521: “Purity requires modesty. This is an integral part of temperance. Modesty preserves the intimacy of the person. It signifies the refusal to reveal what must remain hidden. It is ordered to chastity, of which it attests the delicacy. It guides looks and gestures in conformity with the dignity of persons and their union.”
47Catechism of the Catholic Church, § 2522: “Modesty protects the mystery of persons and their love. It invites patience and moderation in the loving relationship […]. Modesty is decency. It inspires the choice of clothing. It maintains silence or reserve where there is evident risk of unhealthy curiosity. It is discreet.”
48Catechism of the Catholic Church, § 2341: “The virtue of chastity is placed under the influence of the cardinal virtue of temperance, which aims to imbue reason into the passions and appetites of human sensitivity.”
49Saint Thomas Aquinas, Summa Theologica, II-II, q. 153, a. 5 (circa 1271-1272): following Saint Gregory the Great (Moralia in Job, XXXI, 45), Thomas lists the eight “daughters of lust” — blindness of the mind, thoughtlessness (carelessness), inconstancy, rashness, self-love, hatred of God, attachment to the present world, and horror or despair of the world to come. On chastity as part of temperance, cf. q. 151, a. 1-2: chastity is a special virtue, “which moderates the desire and use of sexual pleasures according to reason.”
50Catechism of the Catholic Church, § 2531 (“In brief”): “Purity of heart will enable us to see God: it already allows us to see everything according to God.” See also § 2532: “The purification of the heart requires prayer, the practice of chastity, purity of intention and gaze.”
