August — Chastity
The sixth commandment of the decalogue is called the difficult commandment; the virtue of chastity is called the angelic virtue. Perhaps it is only right that the virtue that makes man most like an angel should be the most difficult to practice perfectly; always the best things must be paid for at the highest price.
But Christian men and women of today have not only their own unruly flesh and the suggestions of the devil to conquer in attaining chastity; they must contend likewise with the concerted efforts of the world around them to make chastity seem either impossible or not worthwhile. Pseudo-intellectuals scoff at chastity, and if some of them could have their way, concepts like immodesty, adultery, lust, sensuality, etc., would be stricken from the minds of all mankind. Many who do not go so far as to deny the virtue of chastity in theory, nevertheless live as if it were impossible of attainment, and frankly tell their friends and neighbors that it is impossible for them, too. Worst of all, there are some Catholics (so called) who join hands with the pagan world in discouraging the practice of chastity. Count among them those who both practice and preach birth-prevention; those who philander while married themselves, or with others who are married; those who take part in the dissemination of obscene and inflammatory incentives to lust. Chastity becomes doubly difficult in the face of such influences to the contrary.
Chastity is defined as the virtue by which, with the help of God's grace attained by prayer and the Sacraments, human beings are enabled to refrain from all misuse of their sex faculties. This implies two things: 1) that they never directly desire or consent to sex-pleasure outside the sphere and contrary to the purposes for which sex-pleasure was intended. The proper sphere of sex activity is the state of marriage, and there it is intended as a means of procreation and of the expression of love between husband and wife. To directly desire and seek sex-pleasure in marriage while excluding by interference the purpose of procreation, or to desire and indulge it in any direct way outside of marriage, would always be a grave sin. 2) The definition of chastity also implies that human beings must avoid those unnecessary actions that indirectly but usually lead to indulgence in sex-pleasure, even though the latter be not intended at the beginning. Thus to read obscene books would be seriously inducive to consent in sex-pleasure. Sometimes, of course, an unnecessary action is only slightly inducive to consent to sinful pleasure; in that case it would constitute a venial sin.
Misunderstanding arises in the minds of some by the oft-quoted principle: In matters of chastity there is no lightness of matter; every sin is a grave sin. This is true, it must be known, in regard to all direct and voluntary desires and indulgences in sex-pleasure outside of marriage or contrary to the purpose of sex. Nevertheless, some sins against chastity may be venial because of lack of full consent of the will, or because of lack of full deliberation, or because an action, such as a momentary indecent glance, or a passing thought, could not be called gravely inducive to sinful consent.
Self-examination on the virtue of chastity must keep these fundamental principles in view.

- Have I gone out of my way to hear impure conversation or taken sinful pleasure in it when I heard it?
- Have I read obscene books or looked at obscene pictures after I knew that they would cause serious temptations to sins of impurity?

- Have I, as a married person, committed sins of impurity with others, and were they married or single?
- Have I failed to correct or train my children in regard to chastity when it was evident that there was need of such correction or training?
- Have I exercised no watchfulness over the company-keeping of my adolescent sons and daughters, permitting and encouraging them to spend long hours alone and in dangerous circumstances?
- Have I bought or sold, lent or given, obscene books or magazines or other objects to be used for impure purposes?
II. Venial Sins
- Have I, without a reason, read books or magazines that were at least dangerous, or concerned only with impassioned love?
- Have I allowed my eyes to wander in curiosity over dangerous objects?
- Have I been slow and half-hearted in trying to banish bad thoughts and desires?
- Have I permitted decent expressions of love or friendship for another to be prolonged to the point of danger of lust?
- Have I gone to shows or movies that I knew to be somewhat dangerous, at least in part?
- Have I been careless about my clothing, posture, appearance, thus exposing others to some danger?
- Have I shown half-deliberate interest in the evil conversation of others?
- Have I, on the spur of the moment, uttered double-meaning words or phrases?
- Have I sought out or continued companionship with others whom I knew to be inclined to evil jests and words?
- Have I supported the publishers of daring and dangerous picture magazines or of borderline periodicals by buying or spreading their publications in any way?
- Have I neglected to use special opportunities of grace and prayer when I was passing through a period of more than usual temptation?
- Have I failed to check vigorously impulses and daydreams of unruly love and affection?
III. Helps And Counsels
- Have I learned the necessity of praying daily for the grace to remain pure?
- Have I acquired the habit of saying an ejaculatory prayer when evil thoughts, desires or inclinations arise?
- Have I made regular or frequent use of the Sacraments of Confession and Holy Communion as a means of strength against impurity?
- Have I practiced any special devotion to Mary, the Virgin Mother of God, whose example and intercession are powerful aids to purity?
- Have I trained my will power for strength in temptation by practicing some form of voluntary mortification?
- Have I tried to avoid idleness, daydreaming, sloth, knowing that to keep occupied is one of the best defenses against impurity?
- Have I made known even my serious temptations in confession, realizing that to reveal temptations is to gain strength against them?
- Have I been diligent in observing even the smaller rules of modesty, such as not to touch others even carelessly, and not to let my eyes wander too freely in public?
Aspiration: O Mary, through thy Immaculate Conception, keep my body pure and my soul holy. (300 days indulgence.) 
Prayer: O Lord Jesus Christ, who hast said; "Blessed are the clean of heart, for they shall see God," grant me the grace of spotless chastity. Thou didst favor St. John with a special mark of Thy friendship because of Thy great love for the holy virtue; let me practice this virtue according to my state that I, too, may be Thy special friend. I am sorry for every fault committed against purity in the past; for every undisciplined thought, for every evil word, for every sensual or impure action. For the future I promise that I shall call upon Thy name and the name of Thy Immaculate Mother in every temptation that assails me; I shall avoid every occasion of sin that might lead me to seek for sinful gratification; I shall insist on chastity in word and deed from those around me; and I shall mortify my body in order that it may be strengthened against the assaults of evil desire. Moreover, I shall try to make some atonement for all the sins that are committed against chastity in the world, which made Thy physical pain so great in Thy bitter passion. I dedicate my life to the defense of this virtue, that the Christian home may be defended and protected and that many souls may be saved from the terrible condemnation that impurity must receive. O Mary, Immaculate Mother, inspire in my heart thy own great love of the virtue of purity.
Woe to you, Scribes and Pharisees, hypocrites! because you clean the outside of the cup and the dish, but within they are full of robbery and uncleanness. Thou blind Pharisee! clean first the inside of the cup and of the dish, that the outside, too, may be clean.
Woe to you, Scribes and Pharisees, hypocrites! because you are like whited sepulchres, which outwardly appear to men beautiful, but within are full of dead men's bones and of all unclean-ness. So you also outwardly appear just to men, but within you are full of hypocrisy and iniquity. —Matthew 23:25-28
