“No more silence! Shout with a hundred thousand tongues! I am seeing the world going to ruin because people are not speaking out.” Saint Catherine of Siena.
Saint Catherine of Siena, a religious mystic of the 14th century, relays words of Our Lord Jesus Christ about the vice against nature, which contaminated part of the clergy in her time. Referring to sacred ministers, He says: “They not only fail from resisting this frailty [of fallen human nature] … but do even worse as they commit the cursed sin against nature. Like the blind and stupid, having dimmed the light of their understanding, they do not recognize the disease and misery in which they find themselves. For this not only causes Me nausea, but displeases even the demons themselves, whom these miserable creatures have chosen as their lords. For Me, this sin against nature is so abominable that, for it alone, five cities were submersed, by virtue of the judgment of My Divine Justice, which could no longer bear them…. It is disagreeable to the demons, not because evil displeases them and they find pleasure in good, but because their nature is angelic and thus is repulsed upon seeing such an enormous sin being committed. It is true that it is the demon who hits the sinner with the poisoned arrow of lust, but when a man carries out such a sinful act, the demon leaves.” (St. Catherine of Siena, El diálogo, in Obras de Santa Catarina de Siena (Madrid: BAC, 1991), p. 292)

For men are most anxious to find truth, but very reluctant to accept it. ... In short, finding out truth is not so hard; what is hard is not to run away from truth once we have found it.... The greatest among philosophers are those who do not flinch in the presence of truth, but welcome it with the simple words: yes, Amen. Saint Thomas Aquinas

"This utterly diseased queen of Sodom renders him who obeys the laws of her tyranny infamous to men and odious to God. ...She strips her knights of the armor of virtue, exposing them to be pierced by the spears of every vice. ...She humiliates her slave in the church and condemns him in court; she defiles him in secret and dishonors him in public; she gnaws at his conscience like a worm and consumes his flesh like fire ... she mobilizes him in the militia of the evil spirit and force him to fight unspeakable wars against God . She detaches the unhappy soul from the company of the angels and , depriving it of it excellence, take it captive under her domineering yoke. Once this poisonous serpent has sunk its fangs into this unfortunate man is deprived of all moral sense, his memory fails, and the mind's vision is darkened. Unmindful of God, he also forgets his own identity. This disease erodes the foundation of faith, saps the vitality of hope, dissolves the bond of love. It makes away with justice, demolishes fortitude, removes temperance, and blunts the edge of prudence. Shall I say more?"- St. Peter Damian -Liber Gomorrhianus ad Leonem IX Romanum Pontificem

IN BRIEF
2392 "Love is the fundamental and innate vocation of every human being" (FC 11).
2393 By creating the human being man and woman, God gives personal dignity equally to the one and the other. Each of them, man and woman, should acknowledge and accept his sexual identity.
2394 Christ is the model of chastity. Every baptized person is called to lead a chaste life, each according to his particular state of life.
2395 Chastity means the integration of sexuality within the person. It includes an apprenticeship in self-mastery.
2396 Among the sins gravely contrary to chastity are masturbation, fornication, pornography, and homosexual practices.
2397 The covenant which spouses have freely entered into entails faithful love. It imposes on them the obligation to keep their marriage indissoluble.
2398 Fecundity is a good, a gift and an end of marriage. By giving life, spouses participate in God's fatherhood.
2399 The regulation of births represents one of the aspects of responsible fatherhood and motherhood. Legitimate intentions on the part of the spouses do not justify recourse to morally unacceptable means (for example, direct sterilization or contraception).
2400 Adultery, divorce, polygamy, and free union are grave offenses against the dignity of marriage.

The sixth Commandment:
"You shall not commit adultery."

"You have heard that it was said, 'You shall not commit adultery.'
But I say to you that every one who looks at a woman lustfully has already committed adultery with her in his heart." (Mt. 5:27-28)
“You shall not commit impure acts”
492. What are the principal sins against chastity?
2351-2359
2396
Grave sins against chastity differ according to their object: adultery, masturbation, fornication, pornography, prostitution, rape, and homosexual acts. These sins are expressions of the vice of lust. These kinds of acts committed against the physical and moral integrity of minors become even more grave. Compendium of the Catechism.
493. Although it says only “you shall not commit adultery” why does the sixth commandment forbid all sins against chastity?
2336
Although the biblical text of the Decalogue reads “you shall not commit adultery” (Exodus 20:14), the Tradition of the Church comprehensively follows the moral teachings of the Old and New Testaments and considers the sixth commandment as encompassing all sins against chastity.

What the Catholic Church Teaches
"Lust is disordered desire for or inordinate enjoyment of sexual pleasure. Sexual pleasure is morally disordered when sought for itself, isolated from its procreative and unitive purposes.
By masturbation is to be understood the deliberate stimulation of the genital organs in order to derive sexual pleasure. Both the Magisterium of the Church, in the course of a constant tradition, and the moral sense of the faithful have been in no doubt and have firmly maintained that masturbation is an intrinsically and gravely disordered action.
The deliberate use of the sexual faculty, for whatever reason, outside of marriage is essentially contrary to its purpose. For here sexual pleasure is sought outside of the sexual relationship which is demanded by the moral order and in which the total meaning of mutual self-giving and human procreation in the context of true love is achieved.
Fornication is carnal union between an unmarried man and an unmarried woman. It is gravely contrary to the dignity of persons and of human sexuality which is naturally ordered to the good of spouses and the generation and education of children.
Moreover, it is a grave scandal when there is corruption of the young.
Pornography consists in removing real or simulated sexual acts from the intimacy of the partners, in order to display them deliberately to third parties.
It offends against chastity because it perverts the conjugal act, the intimate giving of spouses to each other. It does grave injury to the dignity of its participants, (actors, vendors, the public), since each one becomes an object of base pleasure and illicit profit for others.
It immerses all who are involved in the illusion of a fantasy world.
It is a grave offense.
Civil authorities should prevent the production and distribution of pornographic materials."
2355 Prostitution does injury to the dignity of the person who engages in it, reducing the person to an instrument of sexual pleasure. The one who pays sins gravely against himself: he violates the chastity to which his Baptism pledged him and defiles his body, the temple of the Holy Spirit.140 Prostitution is a social scourge. It usually involves women, but also men, children, and adolescents (The latter two cases involve the added sin of scandal.). While it is always gravely sinful to engage in prostitution, the imputability of the offense can be attenuated by destitution, blackmail, or social pressure.
2356 Rape is the forcible violation of the sexual intimacy of another person. It does injury to justice and charity. Rape deeply wounds the respect, freedom, and physical and moral integrity to which every person has a right. It causes grave damage that can mark the victim for life. It is always an intrinsically evil act. Graver still is the rape of children committed by parents (incest) or those responsible for the education of the children entrusted to them.
- Catechism of the Catholic Church (2351-56) 224
What does the ninth Commandment forbid?

Lesson 39:
The Sixth and Ninth Commandments

"But the body is not for fornication, but for the Lord, and the Lord for the body. Now God hath both raised up the Lord, and will raise us up also by His power. Know you not that your bodies are the members of Christ? Shall I then take the members of Christ, and make them the members of an harlot? God forbid. Or know you not, that he who is joined to a harlot, is made one body? For they shall be, saith he, two in one flesh. But he who is joined to the Lord, is one spirit. Fly fornication. Every sin that a man doth, is without the body; but he that committeth fornication, sinneth against his own body. Or know you not, that your members are the temple of the Holy Ghost, who is in you, whom you have from God; and you are not your own? For you are bought with a great price. Glorify and bear God in your body." (1 Corinthians 6:13-20)
What is the Sixth Commandment?
Thou shalt not commit adultery.

What is the Ninth Commandment?
Thou shalt not covet thy neighbor's wife.

What do these commandments oblige you to do?
To practice the virtue of chastity according to your state in life.
Chastity regulates the use of sex for married people. Chastity forbids any use of sex, complete or incomplete, to unmarried people. This also includes those who are engaged.

Who are the only ones who may engage in sex?
Only husband and wife who are validly married to each other, and only in the natural manner, with their proper marriage partner, and only in a manner that leaves open the conception of a child.

Name some of the sins against the Sixth Commandment.
Adultery
Birth Control
Fornication
Sins against nature
Self-abuse
Immodest dressing
Impure touches, looks, kisses, dancing, reading
Looking at impure pictures, dances, shows, movies
Keeping company with people who are a temptation.

What is adultery?
Sexual intercourse which a married person has with someone to whom he (or she) is not married.
"For fornicators and adulterers God will judge." (Hebrews 13:4)

"Neither fornicators... nor adulterers... shall possess the kingdom of God." (1 Corinthians 6:9-10)

What is fornication?
Sexual intercourse between an unmarried man and an unmarried woman.

What is self-abuse?
Enjoying the sexual pleasure alone; also called masturbation.

What are sins against nature?
Perversions committed with oneself, with another person or with animals.
"Do not err: neither fornicators, nor idolaters, nor adulterers, nor the effeminate, nor liars with mankind [i.e., practicing homosexuals] shall possess the kingdom of God." (1 Corinthians 6:9-10)

What is forbidden by the Ninth Commandment?
Impure thoughts and desires.
"But I say to you that whosoever shall look on a woman to lust after her, hath already committed adultery with her in his heart." (Matthew 5:28)

What kind of sin are sins of sex - that is, all impure acts, thoughts, and desires?
Every sin of impurity is a mortal sin, unless not fully consented to, as could happen, for example, with impure thoughts.
A temptation is not a sin. If you reject a temptation, you do a good act and receive extra grace.

When do you become guilty of impure thoughts?
When you knowingly and willingly keep such thoughts in your mind, but especially in taking pleasure in them.
"For from within out of the heart of men proceed evil thoughts, adulteries, fornications, murders." (Mark 7:21)

Is it possible to lead a pure life?
Yes, with God's help --
If you stay away from all persons, places or things which easily lead into sin.
If you pray often (especially to the Blessed Virgin Mary and especially pray her Holy Rosary) and go to Confession and receive Communion regularly.
If you keep busy.
If you flee from temptations when they first appear (do not "toy" with sexual temptation).
If you practice giving up things you like and doing things you do not like.
"And every one that striveth for the mastery, refraineth himself from all things: and they indeed that they may receive a corruptible crown; but we an incorruptible one." (1 Corinthians 9:25)
PRACTICAL POINTS
A Catholic today must bear in mind that he is living in a mostly pagan world and that many things which the world takes for granted are in fact sins or at least serious temptations that must be avoided. Television shows, videos, wearing apparel, etc... must be evaluated with a Catholic conscience and not with the eyes of the world.

and they may come to their senses and escape from the snare of the devil, having been held captive by him to do his will.

“[The vice of sodomy] she mobilizes him in the militia of the evil spirit and force him to fight unspeakable wars against God . She detaches the unhappy soul from the company of the angels and , depriving it of it excellence, take it captive under her domineering yoke” (...)Once this poisonous serpent has sunk its fangs into this unfortunate man, he is deprived of all moral sense, his memory fails , and the mind's vision is darkened. Unmindful of God , he also forgets his own identity. St. Peter Damian -Liber Gomorrhianus ad Leonem IX Romanum Pontificem

Romans 1 26 Because of this, God gave them over to shameful lusts. Even their women exchanged natural relations for unnatural ones.
27 In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed indecent acts with other men, and received in themselves the due penalty for their perversion.
28 Furthermore, since they did not think it worth while to retain the knowledge of God, he gave them over to a depraved mind, to do what ought not to be done.

This utterly diseased queen of Sodom renders him who obeys the laws of her tyranny infamous to men and odious to God. ...She strips her knights of the armor of virtue, exposing them to be pierced by the spears of every vice. ...She humiliates her slave in the church and condemns him in court; she defiles him in secret and dishonors him in public; she gnaws at his conscience like a worm and consumes his flesh like fire ...this unfortunate man (he) is deprived of all moral sense, his memory fails, and the mind's vision is darkened. Unmindful of God, he also forgets his own identity. This disease erodes the foundation of faith, saps the vitality of hope, dissolves the bond of love. It makes away with justice, demolishes fortitude, removes temperance, and blunts the edge of prudence. Shall I say more? St. Peter Damian -Liber Gomorrhianus ad Leonem IX Romanum Pontificem

Saint Bonaventure, speaking in a sermon at the church of Saint Mary of Portiuncula about the miracles that took place simultaneously with the birth of our Lord Jesus Christ, narrates this: “Seventh prodigy: All sodomites—men and women—died all over the earth, as Saint Jerome said in his commentary on the psalm ‘The light was born for the just.’ This made it clear that He was born to reform nature and promote chastity.” (St. Bonaventure, Sermon XXI—In Nativitate Domini, in Catolicismo (Campos/Sao Paulo), December 1987, p. 3; F. Bernardei, op. cit., p. 11)
