1776 "Deep within his conscience man discovers a law which he has not laid upon himself but which he must obey. Its voice, ever calling him to love and to do what is good and to avoid evil, sounds in his heart at the right moment.... For man has in his heart a law inscribed by God.... His conscience is man's most secret core and his sanctuary. There he is alone with God whose voice echoes in his depths."[47]


1777 Moral conscience,[48] present at the heart of the person, enjoins him at the appropriate moment to do good and to avoid evil. It also judges particular choices, approving those that are good and denouncing those that are evil.[49] It bears witness to the authority of truth in reference to the supreme Good to which the human person is drawn, and it welcomes the commandments. When he listens to his conscience, the prudent man can hear God speaking.

1778 Conscience is a judgment of reason whereby the human person recognizes the moral quality of a concrete act that he is going to perform, is in the process of performing, or has already completed. In all he says and does, man is obliged to follow faithfully what he knows to be just and right. It is by the judgment of his conscience that man perceives and recognizes the prescriptions of the divine law:
Conscience is a law of the mind; yet [Christians] would not grant that it is nothing more; I mean that it was not a dictate, nor conveyed the notion of responsibility, of duty, of a threat and a promise.... [Conscience] is a messenger of him, who, both in nature and in grace, speaks to us behind a veil, and teaches and rules us by his representatives. Conscience is the aboriginal Vicar of Christ.[50]

1779 It is important for every person to be sufficiently present to himself in order to hear and follow the voice of his conscience. This requirement of interiority is all the more necessary as life often distracts us from any reflection, self-examination or introspection:
Return to your conscience, question it.... Turn inward, brethren, and in everything you do, see God as your witness.[51]

1780 The dignity of the human person implies and requires uprightness of moral conscience. Conscience includes the perception of the principles of morality (synderesis); their application in the given circumstances by practical discernment of reasons and goods; and finally judgment about concrete acts yet to be performed or already performed. The truth about the moral good, stated in the law of reason, is recognized practically and concretely by the prudent judgment of conscience. We call that man prudent who chooses in conformity with this judgment.

1781 Conscience enables one to assume responsibility for the acts performed. If man commits evil, the just judgment of conscience can remain within him as the witness to the universal truth of the good, at the same time as the evil of his particular choice. The verdict of the judgment of conscience remains a pledge of hope and mercy. In attesting to the fault committed, it calls to mind the forgiveness that must be asked, the good that must still be practiced, and the virtue that must be constantly cultivated with the grace of God:
We shall . . . reassure our hearts before him whenever our hearts condemn us; for God is greater than our hearts, and he knows everything.[52]

1782 Man has the right to act in conscience and in freedom so as personally to make moral decisions. "He must not be forced to act contrary to his conscience. Nor must he be prevented from acting according to his conscience, especially in religious matters."[53]


1783 Conscience must be informed and moral judgment enlightened. A well-formed conscience is upright and truthful. It formulates its judgments according to reason, in conformity with the true good willed by the wisdom of the Creator. The education of conscience is indispensable for human beings who are subjected to negative influences and tempted by sin to prefer their own judgment and to reject authoritative teachings.

1784 The education of the conscience is a lifelong task. From the earliest years, it awakens the child to the knowledge and practice of the interior law recognized by conscience. Prudent education teaches virtue; it prevents or cures fear, selfishness and pride, resentment arising from guilt, and feelings of complacency, born of human weakness and faults. The education of the conscience guarantees freedom and engenders peace of heart.

1785 In the formation of conscience the Word of God is the light for our path,[54] we must assimilate it in faith and prayer and put it into practice. We must also examine our conscience before the Lord's Cross. We are assisted by the gifts of the Holy Spirit, aided by the witness or advice of others and guided by the authoritative teaching of the Church.[55]


1786 Faced with a moral choice, conscience can make either a right judgment in accordance with reason and the divine law or, on the contrary, an erroneous judgment that departs from them.

1787 Man is sometimes confronted by situations that make moral judgments less assured and decision difficult. But he must always seriously seek what is right and good and discern the will of God expressed in divine law.

1788 To this purpose, man strives to interpret the data of experience and the signs of the times assisted by the virtue of prudence, by the advice of competent people, and by the help of the Holy Spirit and his gifts.

1789 Some rules apply in every case:
- One may never do evil so that good may result from it;
- the Golden Rule: "Whatever you wish that men would do to you, do so to them."[56]
- charity always proceeds by way of respect for one's neighbor and his conscience: "Thus sinning against your brethren and wounding their conscience . . . you sin against Christ."[57] Therefore "it is right not to . . . do anything that makes your brother stumble."[58]


1790 A human being must always obey the certain judgment of his conscience. If he were deliberately to act against it, he would condemn himself. Yet it can happen that moral conscience remains in ignorance and makes erroneous judgments about acts to be performed or already committed.

1791 This ignorance can often be imputed to personal responsibility. This is the case when a man "takes little trouble to find out what is true and good, or when conscience is by degrees almost blinded through the habit of committing sin."[59] In such cases, the person is culpable for the evil he commits.

1792 Ignorance of Christ and his Gospel, bad example given by others, enslavement to one's passions, assertion of a mistaken notion of autonomy of conscience, rejection of the Church's authority and her teaching, lack of conversion and of charity: these can be at the source of errors of judgment in moral conduct.

1793 If - on the contrary - the ignorance is invincible, or the moral subject is not responsible for his erroneous judgment, the evil committed by the person cannot be imputed to him. It remains no less an evil, a privation, a disorder. One must therefore work to correct the errors of moral conscience.

1794 A good and pure conscience is enlightened by true faith, for charity proceeds at the same time "from a pure heart and a good conscience and sincere faith."[60]
The more a correct conscience prevails, the more do persons and groups turn aside from blind choice and try to be guided by objective standards of moral conduct.[61]


1795 "Conscience is man's most secret core, and his sanctuary. There he is alone with God whose voice echoes in his depths" (GS 16).

1796 Conscience is a judgment of reason by which the human person recognizes the moral quality of a concrete act.

1797 For the man who has committed evil, the verdict of his conscience remains a pledge of conversion and of hope.

1798 A well-formed conscience is upright and truthful. It formulates its judgments according to reason, in conformity with the true good willed by the wisdom of the Creator. Everyone must avail himself of the means to form his conscience.

1799 Faced with a moral choice, conscience can make either a right judgment in accordance with reason and the divine law or, on the contrary, an erroneous judgment that departs from them.

1800 A human being must always obey the certain judgment of his conscience.

1801 Conscience can remain in ignorance or make erroneous judgments. Such ignorance and errors are not always free of guilt.

1802 The Word of God is a light for our path. We must assimilate it in faith and prayer and put it into practice. This is how moral conscience is formed.


1803 "Whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is gracious, if there is any excellence, if there is anything worthy of praise, think about these things."[62]
A virtue is an habitual and firm disposition to do the good. It allows the person not only to perform good acts, but to give the best of himself. The virtuous person tends toward the good with all his sensory and spiritual powers; he pursues the good and chooses it in concrete actions.

The goal of a virtuous life is to become like God.[63]


1804 Human virtues are firm attitudes, stable dispositions, habitual perfections of intellect and will that govern our actions, order our passions, and guide our conduct according to reason and faith. They make possible ease, self-mastery, and joy in leading a morally good life. The virtuous man is he who freely practices the good.
The moral virtues are acquired by human effort. They are the fruit and seed of morally good acts; they dispose all the powers of the human being for communion with divine love.

The cardinal virtues

1805 Four virtues play a pivotal role and accordingly are called "cardinal"; all the others are grouped around them. They are: prudence, justice, fortitude, and temperance. "If anyone loves righteousness, [Wisdom's] labors are virtues; for she teaches temperance and prudence, justice, and courage."[64] These virtues are praised under other names in many passages of Scripture.

1806 Prudence is the virtue that disposes practical reason to discern our true good in every circumstance and to choose the right means of achieving it; "the prudent man looks where he is going."[65] "Keep sane and sober for your prayers."[66] Prudence is "right reason in action," writes St. Thomas Aquinas, following Aristotle.[67] It is not to be confused with timidity or fear, nor with duplicity or dissimulation. It is called auriga virtutum (the charioteer of the virtues); it guides the other virtues by setting rule and measure. It is prudence that immediately guides the judgment of conscience. The prudent man determines and directs his conduct in accordance with this judgment. With the help of this virtue we apply moral principles to particular cases without error and overcome doubts about the good to achieve and the evil to avoid.

1807 Justice is the moral virtue that consists in the constant and firm will to give their due to God and neighbor. Justice toward God is called the "virtue of religion." Justice toward men disposes one to respect the rights of each and to establish in human relationships the harmony that promotes equity with regard to persons and to the common good. The just man, often mentioned in the Sacred Scriptures, is distinguished by habitual right thinking and the uprightness of his conduct toward his neighbor. "You shall not be partial to the poor or defer to the great, but in righteousness shall you judge your neighbor."[68] "Masters, treat your slaves justly and fairly, knowing that you also have a Master in heaven."[69]

1808 Fortitude is the moral virtue that ensures firmness in difficulties and constancy in the pursuit of the good. It strengthens the resolve to resist temptations and to overcome obstacles in the moral life. The virtue of fortitude enables one to conquer fear, even fear of death, and to face trials and persecutions. It disposes one even to renounce and sacrifice his life in defense of a just cause. "The Lord is my strength and my song."[70] "In the world you have tribulation; but be of good cheer, I have overcome the world."[71]

1809 Temperance is the moral virtue that moderates the attraction of pleasures and provides balance in the use of created goods. It ensures the will's mastery over instincts and keeps desires within the limits of what is honorable. The temperate person directs the sensitive appetites toward what is good and maintains a healthy discretion: "Do not follow your inclination and strength, walking according to the desires of your heart."[72] Temperance is often praised in the Old Testament: "Do not follow your base desires, but restrain your appetites."[73] In the New Testament it is called "moderation" or "sobriety." We ought "to live sober, upright, and godly lives in this world."[74]
To live well is nothing other than to love God with all one's heart, with all one's soul and with all one's efforts; from this it comes about that love is kept whole and uncorrupted (through temperance). No misfortune can disturb it (and this is fortitude). It obeys only [God] (and this is justice), and is careful in discerning things, so as not to be surprised by deceit or trickery (and this is prudence).[75]

The virtues and grace

1810 Human virtues acquired by education, by deliberate acts and by a perseverance ever-renewed in repeated efforts are purified and elevated by divine grace. With God's help, they forge character and give facility in the practice of the good. The virtuous man is happy to practice them.

1811 It is not easy for man, wounded by sin, to maintain moral balance. Christ's gift of salvation offers us the grace necessary to persevere in the pursuit of the virtues. Everyone should always ask for this grace of light and strength, frequent the sacraments, cooperate with the Holy Spirit, and follow his calls to love what is good and shun evil.


1812 The human virtues are rooted in the theological virtues, which adapt man's faculties for participation in the divine nature:[76] for the theological virtues relate directly to God. They dispose Christians to live in a relationship with the Holy Trinity. They have the One and Triune God for their origin, motive, and object.

1813 The theological virtues are the foundation of Christian moral activity; they animate it and give it its special character. They inform and give life to all the moral virtues. They are infused by God into the souls of the faithful to make them capable of acting as his children and of meriting eternal life. They are the pledge of the presence and action of the Holy Spirit in the faculties of the human being. There are three theological virtues: faith, hope, and charity.[77]


1814 Faith is the theological virtue by which we believe in God and believe all that he has said and revealed to us, and that Holy Church proposes for our belief, because he is truth itself. By faith "man freely commits his entire self to God."[78] For this reason the believer seeks to know and do God's will. "The righteous shall live by faith." Living faith "work[s] through charity."[79]

1815 The gift of faith remains in one who has not sinned against it.[80] But "faith apart from works is dead":[81] when it is deprived of hope and love, faith does not fully unite the believer to Christ and does not make him a living member of his Body.

1816 The disciple of Christ must not only keep the faith and live on it, but also profess it, confidently bear witness to it, and spread it: "All however must be prepared to confess Christ before men and to follow him along the way of the Cross, amidst the persecutions which the Church never lacks."[82] Service of and witness to the faith are necessary for salvation: "So every one who acknowledges me before men, I also will acknowledge before my Father who is in heaven; but whoever denies me before men, I also will deny before my Father who is in heaven."[83]


1817 Hope is the theological virtue by which we desire the kingdom of heaven and eternal life as our happiness, placing our trust in Christ's promises and relying not on our own strength, but on the help of the grace of the Holy Spirit. "Let us hold fast the confession of our hope without wavering, for he who promised is faithful."[84] "The Holy Spirit . . . he poured out upon us richly through Jesus Christ our Savior, so that we might be justified by his grace and become heirs in hope of eternal life."[85]

1818 The virtue of hope responds to the aspiration to happiness which God has placed in the heart of every man; it takes up the hopes that inspire men's activities and purifies them so as to order them to the Kingdom of heaven; it keeps man from discouragement; it sustains him during times of abandonment; it opens up his heart in expectation of eternal beatitude. Buoyed up by hope, he is preserved from selfishness and led to the happiness that flows from charity.

1819 Christian hope takes up and fulfills the hope of the chosen people which has its origin and model in the hope of Abraham, who was blessed abundantly by the promises of God fulfilled in Isaac, and who was purified by the test of the sacrifice.[86] "Hoping against hope, he believed, and thus became the father of many nations."[87]

1820 Christian hope unfolds from the beginning of Jesus' preaching in the proclamation of the beatitudes. The beatitudes raise our hope toward heaven as the new Promised Land; they trace the path that leads through the trials that await the disciples of Jesus. But through the merits of Jesus Christ and of his Passion, God keeps us in the "hope that does not disappoint."[88] Hope is the "sure and steadfast anchor of the soul . . . that enters . . . where Jesus has gone as a forerunner on our behalf."[89] Hope is also a weapon that protects us in the struggle of salvation: "Let us . . . put on the breastplate of faith and charity, and for a helmet the hope of salvation."[90] It affords us joy even under trial: "Rejoice in your hope, be patient in tribulation."[91] Hope is expressed and nourished in prayer, especially in the Our Father, the summary of everything that hope leads us to desire.

1821 We can therefore hope in the glory of heaven promised by God to those who love him and do his will.[92] In every circumstance, each one of us should hope, with the grace of God, to persevere "to the end"[93] and to obtain the joy of heaven, as God's eternal reward for the good works accomplished with the grace of Christ. In hope, the Church prays for "all men to be saved."[94] She longs to be united with Christ, her Bridegroom, in the glory of heaven:
Hope, O my soul, hope. You know neither the day nor the hour. Watch carefully, for everything passes quickly, even though your impatience makes doubtful what is certain, and turns a very short time into a long one. Dream that the more you struggle, the more you prove the love that you bear your God, and the more you will rejoice one day with your Beloved, in a happiness and rapture that can never end.[95]


1822 Charity is the theological virtue by which we love God above all things for his own sake, and our neighbor as ourselves for the love of God.

1823 Jesus makes charity the new commandment.[96] By loving his own "to the end,"[97] he makes manifest the Father's love which he receives. By loving one another, the disciples imitate the love of Jesus which they themselves receive. Whence Jesus says: "As the Father has loved me, so have I loved you; abide in my love." And again: "This is my commandment, that you love one another as I have loved you."[98]

1824 Fruit of the Spirit and fullness of the Law, charity keeps the commandments of God and his Christ: "Abide in my love. If you keep my commandments, you will abide in my love."[99]

1825 Christ died out of love for us, while we were still "enemies."[100] The Lord asks us to love as he does, even our enemies, to make ourselves the neighbor of those farthest away, and to love children and the poor as Christ himself.[101]
The Apostle Paul has given an incomparable depiction of charity: "charity is patient and kind, charity is not jealous or boastful; it is not arrogant or rude. Charity does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrong, but rejoices in the right. Charity bears all things, believes all things, hopes all things, endures all things."[102]

1826 "If I . . . have not charity," says the Apostle, "I am nothing." Whatever my privilege, service, or even virtue, "if I . . . have not charity, I gain nothing."[103] Charity is superior to all the virtues. It is the first of the theological virtues: "So faith, hope, charity abide, these three. But the greatest of these is charity."[104]

1827 The practice of all the virtues is animated and inspired by charity, which "binds everything together in perfect harmony";[105] it is the form of the virtues; it articulates and orders them among themselves; it is the source and the goal of their Christian practice. Charity upholds and purifies our human ability to love, and raises it to the supernatural perfection of divine love.

1828 The practice of the moral life animated by charity gives to the Christian the spiritual freedom of the children of God. He no longer stands before God as a slave, in servile fear, or as a mercenary looking for wages, but as a son responding to the love of him who "first loved us":[106]
If we turn away from evil out of fear of punishment, we are in the position of slaves. If we pursue the enticement of wages, . . . we resemble mercenaries. Finally if we obey for the sake of the good itself and out of love for him who commands . . . we are in the position of children.[107]

1829 The fruits of charity are joy, peace, and mercy; charity demands beneficence and fraternal correction; it is benevolence; it fosters reciprocity and remains disinterested and generous; it is friendship and communion:
Love is itself the fulfillment of all our works. There is the goal; that is why we run: we run toward it, and once we reach it, in it we shall find rest.[108]


1830 The moral life of Christians is sustained by the gifts of the Holy Spirit. These are permanent dispositions which make man docile in following the promptings of the Holy Spirit.

1831 The seven gifts of the Holy Spirit are wisdom, understanding, counsel, fortitude, knowledge, piety, and fear of the Lord. They belong in their fullness to Christ, Son of David.[109] They complete and perfect the virtues of those who receive them. They make the faithful docile in readily obeying divine inspirations. Let your good spirit lead me on a level path.[110]
For all who are led by the Spirit of God are sons of God . . . If children, then heirs, heirs of God and fellow heirs with Christ.[111]

1832 The fruits of the Spirit are perfections that the Holy Spirit forms in us as the first fruits of eternal glory. The tradition of the Church lists twelve of them: "charity, joy, peace, patience, kindness, goodness, generosity, gentleness, faithfulness, modesty, self-control, chastity."[112]


1833 Virtue is a habitual and firm disposition to do good.

1834 The human virtues are stable dispositions of the intellect and the will that govern our acts, order our passions, and guide our conduct in accordance with reason and faith. They can be grouped around the four cardinal virtues: prudence, justice, fortitude, and temperance.

1835 Prudence disposes the practical reason to discern, in every circumstance, our true good and to choose the right means for achieving it.

1836 Justice consists in the firm and constant will to give God and neighbor their due.

1837 Fortitude ensures firmness in difficulties and constancy in the pursuit of the good.

1838 Temperance moderates the attraction of the pleasures of the senses and provides balance in the use of created goods.

1839 The moral virtues grow through education, deliberate acts, and perseverance in struggle. Divine grace purifies and elevates them.

1840 The theological virtues dispose Christians to live in a relationship with the Holy Trinity. They have God for their origin, their motive, and their object - God known by faith, God hoped in and loved for his own sake.

1841 There are three theological virtues: faith, hope, and charity. They inform all the moral virtues and give life to them.

1842 By faith, we believe in God and believe all that he has revealed to us and that Holy Church proposes for our belief.

1843 By hope we desire, and with steadfast trust await from God, eternal life and the graces to merit it.

1844 By charity, we love God above all things and our neighbor as ourselves for love of God. Charity, the form of all the virtues, "binds everything together in perfect harmony" (Col 3:14).

1845 The seven gifts of the Holy Spirit bestowed upon Christians are wisdom, understanding, counsel, fortitude, knowledge, piety, and fear of the Lord.



1846 The Gospel is the revelation in Jesus Christ of God's mercy to sinners.[113] The angel announced to Joseph: "You shall call his name Jesus, for he will save his people from their sins."[114] The same is true of the Eucharist, the sacrament of redemption: "This is my blood of the covenant, which is poured out for many for the forgiveness of sins."[115]

1847 "God created us without us: but he did not will to save us without us."[116] To receive his mercy, we must admit our faults. "If we say we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just, and will forgive our sins and cleanse us from all unrighteousness."[117]

1848 As St. Paul affirms, "Where sin increased, grace abounded all the more."[118] But to do its work grace must uncover sin so as to convert our hearts and bestow on us "righteousness to eternal life through Jesus Christ ourLord."[119] Like a physician who probes the wound before treating it, God, by his Word and by his Spirit, casts a living light on sin:
Conversion requires convincing of sin; it includes the interior judgment of conscience, and this, being a proof of the action of the Spirit of truth in man's inmost being, becomes at the same time the start of a new grant of grace and love: "Receive the Holy Spirit." Thus in this "convincing concerning sin" we discover a double gift: the gift of the truth of conscience and the gift of the certainty of redemption. The Spirit of truth is the Consoler.[120]


1849 Sin is an offense against reason, truth, and right conscience; it is failure in genuine love for God and neighbor caused by a perverse attachment to certain goods. It wounds the nature of man and injures human solidarity. It has been defined as "an utterance, a deed, or a desire contrary to the eternal law."[121]

1850 Sin is an offense against God: "Against you, you alone, have I sinned, and done that which is evil in your sight."[122] Sin sets itself against God's love for us and turns our hearts away from it. Like the first sin, it is disobedience, a revolt against God through the will to become "like gods,"[123] knowing and determining good and evil. Sin is thus "love of oneself even to contempt of God."[124] In this proud self- exaltation, sin is diametrically opposed to the obedience of Jesus, which achieves our salvation.[125]

1851 It is precisely in the Passion, when the mercy of Christ is about to vanquish it, that sin most clearly manifests its violence and its many forms: unbelief, murderous hatred, shunning and mockery by the leaders and the people, Pilate's cowardice and the cruelty of the soldiers, Judas' betrayal - so bitter to Jesus, Peter's denial and the disciples' flight. However, at the very hour of darkness, the hour of the prince of this world,[126] the sacrifice of Christ secretly becomes the source from which the forgiveness of our sins will pour forth inexhaustibly.


1852 There are a great many kinds of sins. Scripture provides several lists of them. The Letter to the Galatians contrasts the works of the flesh with the fruit of the Spirit: "Now the works of the flesh are plain: fornication, impurity, licentiousness, idolatry, sorcery, enmity, strife, jealousy, anger, selfishness, dissension, factions, envy, drunkenness, carousing, and the like. I warn you, as I warned you before, that those who do such things shall not inherit the Kingdom of God."[127]

1853 Sins can be distinguished according to their objects, as can every human act; or according to the virtues they oppose, by excess or defect; or according to the commandments they violate. They can also be classed according to whether they concern God, neighbor, or oneself; they can be divided into spiritual and carnal sins, or again as sins in thought, word, deed, or omission. The root of sin is in the heart of man, in his free will, according to the teaching of the Lord: "For out of the heart come evil thoughts, murder, adultery, fornication, theft, false witness, slander. These are what defile a man."[128] But in the heart also resides charity, the source of the good and pure works, which sin wounds.
