1. The sixth commandment: you shall not commit adultery 50 CRANACH, Lucas (1472-1553) Christ and the Adulteress Wood, 1532 82.5 x 121 cm Museum of Fine Arts, Budapest

2. Compendium of the Catechism 488. What is chastity? 2337-2338 Chastity means the positive integration of sexuality within the person. Sexuality becomes truly human when it is integrated in a correct way into the relationship of one person to another. Chastity is a moral virtue, a gift of God, a grace, and a fruit of the Holy Spirit. 489. What is involved in the virtue of chastity? 2339-2341 The virtue of chastity involves an apprenticeship in self-mastery as an expression of human freedom directed towards self-giving. An integral and continuing formation, which is brought about in stages, is necessary to achieve this goal.

3. Introduction Saint Paul asks the Corinthians:  Do you not know that your bodies are members of Christ?... Do you not know that your body is a temple of the Holy Spirit within you, which you have from God? You are not your own; you were bought with a price. So glorify God in your body " (1 Corinthians 6:15;19-20). Not only Christians, but all men of reason should respect their own bodies — and others’ — and strive for chastity in thought, word, deed and desire in accordance with reason. DI GIORGIO MARTINI, Francesco Chastity with the Unicorn 1463 Convento dell'Osservanza, Siena, Italia

4. Main ideas

5. 1. Sexuality is a gift from God We should recall the biblical teaching that God created man in his image and likeness, male and female he created them (cf. Genesis 1:27). And since sexuality comes from God, sexuality is good, it is God’s gift. God has arranged an order in the use of sexuality. Thus sexual pleasure — whether in thought, word or deed— should be sought only within marriage and in accordance with God’s plan for human sexuality, that is: the transmission of human life and the communion and mutual aid of the spouses. BOSCH, Hieronymus The Garden of Earthly Delights: Allegory of Luxury, central panel of triptych c.1500 Museo del Prado, Madrid

6. 2. The virtue of chastity Chastity is the virtue which controls sexuality in thought, desire, word and action. It consists in the submission of sexuality to reason and faith. As with all virtues, chastity implies victory over and freedom from slavery to sin. MORELLI, Domenico The Temptation of St. Anthony 1878 Galleria Nazionale d'Arte Moderna, Rome

7. 3. The harm caused by impurity Sins against chastity not only harm men and women’s friendship with God, but also other important virtues. Those who sin against chastity are easily affected by gloom because they become slaves of sin; they lack generosity because they put themselves and pleasure before God; their faith is weakened because their impurity darkens their hearts; and they lose that sensibility which enables them to love God and others. CANO, Alonso Immaculate Conception 1648 Oil on canvas Provincial Museum, Vitoria, Spain

8. 4. Chastity is for all Each of us has to practise chastity according to his vocation and state in life. God calls some to virginity or celibacy as a way of giving their hearts undivided to God, and he asks others to practise chastity in marriage or as single persons. Married people have to practise conjugal chastity by being faithful to their matrimonial duties, and single persons have to practise continence. The marital union of man and woman must be open always to the transmission of life: contraception and sterilization in order to avoid procreation are never licit. HOGARTH, William Henry VIII Private collection

9. 5. Sins against chastity Those sin against chastity who — be they alone or with others —  commit impure acts,  look at impure things,  consent fully to impure thoughts or desires,  talk or tell jokes about impure things,  voluntarily put themselves or others in danger of sin. Sins that clearly violate chastity :  Masturbation, fornication, pornographic and homosexual activities.  Adultery, polygamy and casual sex feature among the sins that go against the dignity of marriage. Such sins against chastity are always serious, if there is full knowledge and deliberate consent. In sins against chastity there is no such thing as a venial matter. ARMITAGE, Edward Herod's Birthday Feast 1868 Ghildhall Art Gallery. London

10. 6. Struggling for chastity To win the battle for chastity one must flee from occasions of sin; in this matter fleeing is not cowardice but prudence. And prudence tells us to avoid friends, reading material, entertainment, conversations, etc., which might lead to sin. Another nugget of wisdom is to keep ourselves occupied with serious work so as not to become engrossed in egoism. But more important is the use of the supernatural means: frequent confession and communion, praying for chastity with humility and perseverance, having recourse to Our Mother the most pure Virgin, etc. LEIGHTON, Frederic Fatidica (c. 1893-94) Lady Lever Art Gallery

11. Resolutions for Christian life

12. Resolutions to move forward Turn to Our Lady when feeling temptations against chastity. Recite the “Memorare” prayer (Remember, O Most Gracious Virgin Mary, …). Strive to be clean in our words, conversations, jokes, etc.
