Peter and Paul, and All Saints (CIC 1917: Can.1247; CIC 1983, Can. 1246). In many countries, by local concessions, they are reduced.]

25 Q. What is forbidden on Fridays, and also on Saturdays where not dispensed?
A. On Fridays, and also on Saturdays where not dispensed, it is forbidden to eat meat, except in case of necessity.

26 Q. Why does the Church wish us to abstain from eating meat on these days?
A. In order that we may do penance each week, and especially on Friday, in honor of the Passion, and on Saturdays in memory of the burial of Jesus Christ, and in honor of the Blessed Virgin.

[From the Code of Canon Law of 1917, with the modifications approved in 1949, (complete) abstinence only is to be observed on all the Fridays throughout the year. Fast and (complete) abstinence is to be observed on Ash Wednesday, the Fridays of Lent, Ember Fridays, the Vigils of the Assumption and Christmas, and Holy Saturday. Fast only (and partial abstinence) is to be observed on: all weekdays of Lent, Ember Wednesdays and Saturdays, and the Vigils of Pentecost and All Saints. On the days of fast, only one full meal is allowed. Two other meatless snacks, sufficient to maintain strength may be taken according to each one’s needs, but together they should not equal another full meal. Meat may be taken at the principal meal on a day of fast except on the days of complete abstinence. Eating between meals is forbidden, but liquids including milk and fruit juices are allowed. On holydays of obligation, except in Lent, there is neither fast nor abstinence.
The laws of abstinence binds all who have completed their seventh year of age; the law of fasting binds all persons from the completion of their twenty first year until the beginning of their sixtieth. (The completion of the seventh year means the day after the seventh birthday). According to the 1983 Code of Canon Law, “All Fridays through the year and the time of Lent are penitential days and times throughout the universal Church. Abstinence from eating meat . . . is to be observed on Fridays throughout the year unless they are solemnities; abstinence and fast are to be observed on Ash Wednesday and (Good) Friday. All adults who have completed their fourteenth year are bound by the law of abstinence; all adults (from age 18) are bound by the law of fast up to the beginning of their sixtieth year.”

The Episcopal Conference can modify these general rules.
In the United States, “Catholics are obliged to abstain from the eating of meat on Ash Wednesday and all Fridays during the season of Lent. They are also obliged to fast on Ash Wednesday and on Good Friday. Self-imposed observances of fasting on all weekdays of Lent is strongly recommended. Abstinence from flesh meat on all Fridays of the year is especially recommended to individuals and to the Catholic community as a whole.”
In Australia, “Abstinence from meat, and fasting, are to be observed on Ash Wednesday and Good Friday. On all other Fridays of the year the law of the common practice of penance is fulfilled by performing any of the following: (a) prayer, as for example Mass attendance, family prayer, . . . (b) self-denial, e.g. not eating meat, not eating sweets or dessert, . . (c) helping others, e.g. special attention to someone who is poor, sick, elderly, . . .”

Since a clarity and precision in a law helps for its fulfillment, the faithful are strongly recommended to follow the traditional rules, though only the recent regulations oblige under pain of mortal sin.]

The Third Precept of the Church

27 Q. What does the Church command us in the words of the Third Precept: To go to Confession at least once a year?
A. By the words of the Third Precept: To go to Confession a least once a year, the Church obliges all Christians, who have come to the use of reason, to approach the sacrament of Penance at least once a year.

28 Q. What is the best time to satisfy the precept of annual Confession?
A. The best time to satisfy the precept of annual Confession is Lent, in accordance with the usage introduced and approved by the whole Church.

29 Q. Why does the Church say that we are to confess at least once a year?
A. The Church uses the words at least to let us see her desire that we should approach the sacraments more frequently.

30 Q. Is it useful, then, to go often to Confession?
A. It is most useful to go often to Confession, especially as it is difficult for one who goes only rarely to make a good Confession and to avoid mortal sin.

31 Q. What does the Church command us to do by the other words of the Third Precept: To receive Holy Communion at Easter, each one in his own parish?
A. By the words of the Third Precept: To receive Holy Communion at Easter, each one in his own parish, the Church obliges all Christians who have come to the age of discretion to receive the Blessed Eucharist every year at Paschal time in their own parish.

32 Q. Are we bound to go to Holy Communion at other times besides Easter?
A. We are also bound to go to Holy Communion when in danger of death.

33 Q. Why is it said that we are to receive Holy Communion at least at Easter?
A. Because the Church earnestly desires us to approach Holy Communion which is the divine food of our souls, not only at Easter, but as often as we possibly can.

34 Q. Is this Precept fulfilled by a sacrilegious Confession or a sacrilegious Communion?
A. This Precept of the Church is not fulfilled by sacrilegious Confession and Communion, because the intention of the Church is that we receive those Sacraments for the end on account of which they were instituted, that is, for our sanctification.

The Fourth Precept of the Church

35 Q. How are we to observe the Fourth Precept: To contribute to due support of the Church?
A. The Fourth Precept is satisfied by paying the dues or making the offerings which have been established in recognition of God’s supreme dominion over all things and as a means of providing for the becoming support of His ministers.

36 Q. How are these dues and offerings to be paid?
A. They are to be paid in the way and manner customary in the place in which we live.

The Fifth Precept of the Church

37 Q. What does the Church forbid in the Fifth Precept: Not to solemnize marriage at forbidden times?
A. In the Fifth Precept the Church does not forbid the celebration of the sacrament of marriage; but only the nuptial solemnities, from the first Sunday of Advent until the Epiphany, and from the first day of Lent until Low Sunday.

38 Q. What are the nuptial solemnities which are forbidden?
A. The nuptial solemnities forbidden by this Precept are the celebration of the nuptial Mass, the nuptial benediction, and marriage festivities on a large scale.

39 Q. Why are marriage festivities on a large scale out of place in Advent and Lent?
A. Pompous displays are out of place in Advent and Lent because these seasons are specially consecrated to penance and prayer.

The Commandments of God in General

A. The Commandments of God and of the Church are treated of in the third part of Christian Doctrine.

2 Q. How many Commandments of God’s Law are there?

3. Remember thou keep holy the Sabbath Day;
4. Honour thy Father and thy Mother,
5. Thou shalt not kill;
6. Thou shalt not commit adultery;
7. Thou shalt not steal;
8. Thou shalt not bear false witness;
9. Thou shalt not covet another’s wife;
10. Thou shalt not covet another’s goods.

3 Q. Why are the Commandments of God so named?
A. The Commandments of God are so named because God Himself has stamped them on the soul of every man; promulgated them, engraved on two tables of stone, on Mount Sinai, in the Old Law; and Jesus Christ has confirmed them in the New Law.

4 Q. Which are the Commandments of the first table?
A. The Commandments of the first table are the first three, which directly regard God and our duties towards Him.

A. The Commandments of the second table are the last seven, which regard our neighbor, and our duties towards him.

6 Q. Are we bound to observe the Commandments?
A. Yes, we are bound to observe the Commandments, because we are all bound to live according to the will of God who created us, and because a serious transgression against even one of them is enough to merit hell.

7 Q. Are we able to observe the Commandments?
A. Yes, without doubt we are able to observe God’s Commandments, because God never commands anything that is impossible, and because He gives grace to observe them to those who ask it as they should.

8 Q. What, in a general way, should we consider in each of the Commandments?
A. In each of the Commandments we should consider its positive part and its negative part, that is, what it commands and what it forbids.

The First Commandment

1 Q. Why is it said at the commencement of the Commandments: I am the Lord thy God?
A. It is said at the commencement of the Commandments: I am the Lord thy God, to show us that God being our Creator and Lord, can command whatever He wills, and that we, being His creatures, are bound to obey Him.

2 Q. In the words of the First Commandment: Thou shalt not have strange gods before Me, what does God command us?
A. By the words of the First Commandment: Thou shalt not have strange gods before Me, He commands us to acknowledge, adore, love and serve Him alone as our Sovereign Lord.

3 Q. How do we fulfill the First Commandment?
A. We fulfill the First Commandment by the practice of internal and external worship.

4 Q. What is internal worship?
A. Internal worship is the honor which is given to God with the faculties of the soul alone, that is with the intellect and the will.

5 Q. What is external worship?
A. External worship is the homage that is given to God by means of outward acts and of sensible objects.

6 Q. Is it not enough internally to adore God with the heart alone?
A. No, it is not enough internally to adore God with the heart alone; we must also adore Him externally with both soul and body, because He is the Creator and absolute Lord of both.

7 Q. Can there be external worship without internal worship?
A. No, in no way can there be external worship without internal, because unless external worship is accompanied by internal, it is destitute of life, of merit, and of efficacy, like a body without a soul

8 Q. What is forbidden by the First Commandment?
A. The First Commandment forbids idolatry, superstition, sacrilege, heresy, and every other sin against religion.

9 Q. What is idolatry?
A. Idolatry is the giving to any creature, for example, to a statue, to an image, or to a man, the supreme worship of adoration that belongs to God alone.

10 Q. How is this prohibition expressed in Holy Scripture?
A. This prohibition is expressed in Holy Scripture in these words: Thou shalt not make to thyself a graven thing, nor the likeness of anything that is in heaven above, or on the earth beneath; and thou shalt not adore them or serve them.

11 Q. Do these words forbid every kind of image?
A. Certainly not; but only those of false divinities, made to be adored, as idolaters adore them. So true is this, that God Himself commanded Moses to make images, as, for example, the two statues of the Cherubim for the Ark, and the Brazen Serpent in the desert.

12 Q. What is superstition?
A. Superstition is any devotion that is contrary to the teaching and practice of the Church; as also the ascribing to any action or any thing whatever a supernatural virtue which it does not possess.

13 Q. What is a sacrilege?
A. A sacrilege is the profanation of a place, of a person, or of a thing consecrated to God and set apart for his worship.

14 Q. What is heresy?
A. Heresy is a culpable error of the intellect by which some truth of faith is obstinately denied.

15 Q. What else does the First Commandment forbid?
A. The First Commandment also forbids all dealings with the devil, and all association with anti-Christian sects.

16 Q. If one were to have recourse to and invoke the devil, would he commit a grave sin?
A. If one were to have recourse to and invoke the devil, he would commit an enormous sin, because the devil is the most wicked enemy both of God and of man.

17 Q. Is it lawful to put questions to speaking or writing tables or in any way to consult the souls of the dead by means of spiritism?
A. All the practices of spiritism are unlawful, because they are superstitious; and often they are not free from diabolical intervention; and hence they are rightly condemned by the Church.

18 Q. Does the First Commandment forbid us to honor and invoke the Angels and Saints?
A. No, it is not forbidden to honor and invoke the Angels and Saints; on the contrary, we should do so, because it is a good and useful practice highly commended by the Church; for they are God’s friends and our intercessors with Him.

19 Q. Since Jesus Christ is our only mediator with God, why have recourse also to the intercession of the Blessed Virgin and the Saints?
A. Jesus Christ is our Mediator with God, because being true God and true man He alone in virtue of His own merits has reconciled us to God and obtains us all graces. But in virtue of the merits of Jesus Christ, and through the charity which unites them to God and us, the Blessed Virgin and the Saints help us by their intercession to obtain the graces we ask. And this is one of the great benefits of the Communion of Saints.

20 Q. May we also honor the sacred images of Jesus Christ and of the Saints?
A. Yes, because the honor we give the sacred images of Jesus Christ and of the Saints is referred to their very persons.

21 Q. May the relics of the Saints be honored?
A. Yes, we should honor the relics of the Saints, because their bodies were living members of Jesus Christ and temples of the Holy Ghost, and will rise gloriously to eternal life.

22 Q. What is the difference between the honor we give to God and the honor we give to the Saints?
A. Between the honor we give to God and the honor we give to the Saints there is this difference, that we adore God because of his infinite excellence, whereas we do not adore the Saints, but honor and venerate them as God’s friends and our intercessors with Him. The honor we give to God is called Latria, that is, the worship of adoration; the honor we give to the Saints is called Dulia, that is, the veneration of the servants of God; while the special honor we give to the Blessed Virgin is called Hyperdulia, that is, a special veneration of the Mother of God.

The Second Commandment

1 Q. What does the Second Commandment: Thou shalt not take the Name of God in vain, forbid?
A. The Second Commandment: Thou shalt not take the Name of God in vain, forbids us: (1) To utter the Name of God irreverently; (2) To blaspheme God, the Blessed Virgin or the Saints; (3) To take false, unnecessary, or unlawful oaths.

2 Q. What is meant by: Not to utter the Name of God irreverently?
A. Not to utter the Name of God irreverently means not to mention this Holy Name, or any other name that in a special way refers to God Himself, such as the name of Jesus, of Mary and the Saints, in anger or in joke or in any irreverent way whatsoever.

3 Q. What is blasphemy?
A. Blasphemy is a horrible sin which consists in words or acts of contempt or malediction against God, the Blessed Virgin, the Saints, or sacred things.

4 Q. Is there any difference between blasphemy and imprecation?
A. There is a difference, because by blasphemy one wishes evil to or curses God, the Blessed Virgin or the Saints; while by imprecation one wishes evil to or curses one’s self or one’s neighbor.

5 Q. What is an oath?
A. An oath is the calling on God to witness the truth of what one says or promises.

6 Q. Is it always forbidden to take an oath?
A. It is not always forbidden to take an oath; an oath is lawful and even gives honor to God, when it is necessary, and when one swears with truth, judgment and justice.

7 Q. When is an oath without truth?
A. When one affirms on oath what he knows or believes to be false, or when one promises under oath to do what one has no intention of doing.

8 Q. When is an oath without judgment?
A. When one makes oaths imprudently and without mature consideration, or in trivial matters.

9 Q. When is an oath without justice?
A. When one makes an oath to do something unjust or unlawful, as, for example, to swear to take revenge, or to steal, and so on.

10 Q. Are we obliged to keep an oath to do unjust or unlawful things?
A. Not only are we not obliged, but we should sin by doing such things, because they are forbidden by the laws of God and of the Church.

11 Q. What sin does he commit who swears falsely?
A. He who swears falsely commits a mortal sin, because he grievously dishonors God, the Infinite Truth, by calling Him to witness what is false.

12 Q. What does the Second Commandment command us to do?
A. The Second Commandment commands us to honor the Holy Name of God as well as to keep our oaths and vows.

13 Q. What is a vow?
A. A vow is a promise made to God regarding something which is good, within our power, and better than its opposite, and to the keeping of which we bind ourselves just as if it had been commanded us.

14 Q. If the keeping of a vow were to become very difficult, in whole or in part, what is to be done?
A. Commutation or dispensation may be sought from one’s Bishop or from the Pope, according to the character of the vow.

15 Q. Is it a sin to break a vow?
A. It is a sin to break a vow and therefore we should not make vows without mature reflection, nor, as a rule, without the advice of our confessor or other prudent person, so as not to expose ourselves to the danger of sinning.

16 Q. May vows be made to our Lady and the Saints?
A. Vows are made to God alone; we may, however, promise God to do something in honor of our Lady or the Saints.

The Third Commandment

1 Q. What does the Third Commandment: Remember thou keep holy the Sabbath day, command us to do?
A. The Third Commandment: Remember thou keep holy the Sabbath day, commands us to honor God by acts of worship on festivals.

2 Q. What are festivals?
A. In the Old Law they were Saturdays and certain other days regarded as specially solemn by the Jews; in the New Law they are Sundays and other festivals instituted by
the Church.

3 Q. Why is Sunday sanctified instead of Saturday in the New Law?
A. Sunday, which means the Lord’s Day, was substituted for Saturday, because it was on that day that our Lord rose from the dead.

4 Q. What act of worship is commanded us on festivals?
A. We are commanded to assist devoutly at the Holy Sacrifice of the Mass.

5 Q. With what other good works does a good Christian sanctify festivals?
A. A good Christian sanctifies festivals: (1) By attending Christian Doctrine, sermons, and the Divine Office; (2) By frequently and devoutly receiving the sacraments of Penance and the Blessed Eucharist; (3) By the practice of prayer and works of Christian charity.

6 Q. What does the Third Commandment forbid?
A. The Third Commandment forbids servile works and any other works that hinder the worship of God.

7 Q. What servile works are forbidden on festivals?
A. The servile works forbidden on festivals are those works called manual, that is, those material works in which the body has more part than the mind, such, for instance, as are ordinarily done by servants, labourers, and artisans.

8 Q. What sin does one commit by working on festivals?
A. One commits a mortal sin by working on festivals; brevity of time, however, will excuse from grave sin.

9 Q. Is no servile work at all permitted on festivals?
A. On festivals those works are permitted which are necessary for life, or for the service of God; as well as those done for a grave reason, with leave, when possible, from the Pastor.

10 Q. Why is servile work forbidden on festivals?
A. Servile work is forbidden on festivals in order that we may the better attend to divine worship, and to the care of our souls; And to enable us to rest from toil. Hence innocent recreation is not forbidden.

11 Q. What else above all should we avoid on festivals?
A. We should above all avoid sin and whatever leads to sin, such as dangerous diversions and dangerous places of amusement.

The Fourth Commandment

1 Q. What does the Fourth Commandment: Honor thy father and thy mother, command?
A. The Fourth Commandment: Honor thy father and thy mother, commands us to respect our parents, obey them in all that is not sinful, and assist them in their temporal and spiritual needs.

2 Q. What does the Fourth Commandment forbid?
A. The Fourth Commandment forbids us to offend our parents by word or by deed or in any other way.

3 Q. What other persons does this Commandment include under the names of father and mother?
A. Under the names of father and mother this Commandment also includes all our superiors, both ecclesiastical and lay, whom we must consequently obey and respect.

4 Q. Whence are derived the authority of parents to command their children and the duty of children to obey their parents?
A. The authority possessed by parents to command their children and the obligation children are under to obey their parents, are derived from God who constituted and established family life in order that in it man might have the first helps that are necessary towards his spiritual and temporal well-being.

5 Q. Have parents any duties towards their children?
A. Parents are bound to love, support and maintain their children; to attend to their religious and secular education; to give them good example; to keep them from the occasions of sin; to correct their faults; and to help them to embrace the state to which God has called them.

6 Q. Has God given us an example of a perfect family?
A. God gave us an example of a perfect family in the Holy Family in which Jesus Christ lived subject to the Blessed Virgin and St. Joseph until His thirtieth year, that is, until He began the Mission of preaching the Gospel entrusted to Him by His Eternal Father.

7 Q. If families were to live alone, cut off one from the other, could they provide for all their material and moral needs?
A. If families lived alone, cut off one from the other, they could not provide for their individual needs, and hence it is necessary that they be united in civil society so as mutually to aid one another for the common good and happiness.

8 Q. What is Civil Society?
A. Civil Society is the union of many families under the authority of one head for the purpose of assisting each other in securing their mutual perfection and temporal happiness.

9 Q. Whence comes the authority which rules Civil Society?
A. The authority which rules Civil Society comes from God, who established it for the common good.

10 Q. Are we under any obligation to obey the authority that governs Civil Society?
A. Yes; all who form part of Civil Society are bound to respect and obey authority because that authority comes from God and because the common good so demands.

11 Q. Are all laws imposed by the Civil Authority to be respected?
A. Yes; in accordance with the command and example of our Lord Jesus Christ, all laws imposed by the Civil Authority are to be respected, provided they are not contrary to the law of God.

12 Q. Have those who form part of Civil Society any other duties besides respect and obedience to the laws imposed by authority?
A. Besides the obligation of respect and obedience to the laws, all those who form part of Civil Society are bound to live in peace, and to endeavor, each according to his means and ability, to render that society virtuous, peaceful, orderly and prosperous.

The Fifth Commandment

1 Q. What does the Fifth Commandment: Thou shalt not kill, forbid?
A. The Fifth Commandment, Thou shalt not kill, forbids us to kill, strike, wound or do any other bodily harm to our neighbor, either of ourselves or by the agency of others; as also to wish him evil, or to offend him by injurious language. In this Commandment God also forbids the taking of one’s own life, or suicide.

2 Q. Why is it a grave sin to kill one’s neighbor?
A. Because the slayer unjustly invades the right which God alone has over the life of man; because he destroys the security of civil society; and because he deprives his neighbor of life, which is the greatest natural good on earth.

3 Q. Are there cases in which it is lawful to kill?
A. It is lawful to kill when fighting in a just war; when carrying out by order of the Supreme Authority a sentence of death in punishment of a crime; and, finally, in cases of necessary and lawful defense of one’s own life against an unjust aggressor.

4 Q. Does God also forbid us in the Fifth Commandment to do harm to the spiritual life of another?
A. Yes, in the Fifth Commandment God also forbids us to do harm to another’s spiritual life by scandal.

5 Q. What is scandal?
A. Scandal is any word, act, or omission which is the occasion of another’s committing sin.

6 Q. Is scandal a grave sin?
A. Scandal is a grave sin because, by causing the loss of souls, it tends to destroy the greatest work of God, namely, the redemption; it effects the death of another’s soul by depriving it of the life of grace, which is more precious than the life of the body; and is the source of a multitude of sins. Hence God threatens the severest chastisement to those who give scandal.

7 Q. Why does God, in the Fifth Commandment, forbid the taking of one’s own life or suicide?
A. In the Fifth Commandment God forbids suicide, because man is not the master of his own life no more than of the life of another. Hence the Church punishes suicide by deprivation of Christian burial.

8 Q. Is dueling also forbidden by the Fifth Commandment?
A. Yes, dueling is also forbidden by the Fifth Commandment, because dueling has in it the guilt both of suicide and of homicide; and whoever voluntarily takes part in it, even as a simple onlooker is excommunicated.

9 Q. Is dueling also forbidden when there is no danger of being killed?
A. This sort of dueling is also forbidden, because not only are we forbidden to kill, but even voluntarily to wound ourselves or others.

10 Q. Is the defense of one’s honor an excuse for dueling?
A. No, because it is not true that the offence is repaired by dueling; and because honor cannot be repaired by an unjust, irrational and barbarous act such as dueling.
