1. What are the 10 Commandments of God? The Ten Commandments of God are:

1. I am the Lord your God; you shall not have strange gods before Me.
2. You shall not take the Name of the Lord your God in vain.
3. Remember to keep holy the Lord's day.
4. Honour your father and your mother.
5. You shall not kill.
6. You shall not commit adultery.
7. You shall not steal.
8. You shall not bear false witness against your neighbour.
9. You shall not covet your neighbour's wife.
10. You shall not covet your neighbour's goods.

2. Where do we find the 10 Commandments? They are found in the Old Testament of the Holy Bible, in the Book of Exodus, Chapter 20, Verses 1 to 17.

3. To who did God give the 10 Commandments? God gave the Ten Commandments to Moses, who in turn gave them to the Jewish people.

4. Are we obligated to keep all the Commandments? Everyone who wishes to serve God and save his own soul must keep all the Commandments of God.

4.1 “If you love Me, you will keep My Commandments.” [Jn. 14:15] “For whoever keeps the whole law but fails in one point has become accountable for all of it.” [Jas. 2:10]

4.2 "Teacher, what good deed must I do, to have eternal life?" To the young man who asked this question, Jesus answered first by invoking the necessity to recognize God as the "One there is who is good," as the supreme Good and the source of all good. Then Jesus tells him: "If you would enter life, keep the commandments." And he cites for his questioner the precepts that concern love of neighbor: "You shall not kill, You shall not commit adultery, You shall not steal, You shall not bear false witness, Honor your father and mother." Finally Jesus sums up these commandments positively: "You shall love your neighbor as yourself." [Mt 19:16-19; C.C.C. # 1858] (Catechism of the Catholic Church # 2052) [Note: "C.C.C." means "Catechism of the Catholic Church.")

5. What did the Council of Trent teach about the Ten Commandments? It teaches that the Ten Commandments are obligatory for Christians and that the justified man is still bound to keep them; [Cf. DS 1569-1570] the Second Vatican Council confirms: "The bishops, successors of the apostles, receive from the Lord... the mission of teaching all peoples, and of preaching the Gospel to every creature, so that all men may attain salvation through faith, Baptism and the observance of the Commandments." (C.C.C. # 2068)


6. What is the First Commandment? It is, “I am the Lord your God; you shall not have strange gods before Me.”

7. What does the First Commandment tell us to do? It commands us to adore God alone.

8. Jesus summed up man's duties toward God in this saying: "You shall love the Lord your God with all your heart, and with all your soul, and with all your mind." [Mt 22:37; cf. Lk 10:27:" ...and with all your strength."] This immediately echoes the solemn call: "Hear, O Israel: the LORD our God is one LORD." [Deut 6:4] God has loved us first. The love of the One God is recalled in the first of the "ten words." The commandments then make explicit the response of love that man is called to give to his God. (C.C.C. # 2083)

9. What is forbidden by this Commandment?

9.1 It forbids us to adore false gods.

9.2 It forbids us to give to anyone or anything the adoration and service that belongs to God alone.

9.3 It forbids us to adore God by false worship.
10. How would the First Commandment be broken in the above different ways? 10.1 By paganism and idolatry. Example: By worshiping the false gods of the heathens. (Note: "Heathens" means those who are irreligious, uncivilized, unenlightened, the unconverted, those who reject the God of Judaism and Christianity.)

10.2 By attributing to persons or things powers that belong to God alone. Example: Believing in the power of fortune tellers to reveal the future, or in the power of spiritualists to bring back the dead or to bring messages from the dead, or in the power of charms to avert evil or to bring “good luck..”

10.3 By wilfully belonging to a religion or a church which is known not to be the True Church established by Jesus Christ.

10.4 By considering all religions as being equal, especially in the area of the Sacrament of the Holy Eucharist.

11. What difference is there between receiving the Sacrament of the Holy Eucharist in the Catholic Church versus receiving the bread from another religion? Only the Holy Catholic Church recognizes the permanent Real Presence of Jesus in the Holy Eucharist once the bread has been consecrated during the Holy Mass.

12. What does the First Commandment teach us about divination and magic? God can reveal the future to his prophets or to other saints. Still, a sound Christian attitude consists in putting oneself confidently into the hands of Providence for whatever concerns the future, and giving up all unhealthy curiosity about it. Improvidence, however, can constitute a lack of responsibility. (C.C.C. # 2115)

13. All forms of divination are to be rejected: recourse to Satan or demons, conjuring up the dead or other practices falsely supposed to "unveil" the future. [Cf. Deut 18:10; Jer 29:8] Consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums all conceal a desire for power over time, history, and, in the last analysis, other human beings, as well as a wish to conciliate hidden powers. They contradict the honor, respect, and loving fear that we owe to God alone. (C.C.C. # 2116)

14. All practices of magic or sorcery, by which one attempts to tame occult powers, so as to place them at one's service and have a supernatural power over others - even if this were for the sake of restoring their health - are gravely contrary to the virtue of religion. These practices are even more to be condemned when accompanied by the intention of harming someone, or when they have recourse to the intervention of demons. Wearing charms is also reprehensible. Spiritism often implies divination or magical practices; the Church for her part warns the faithful against it. Recourse to so-called traditional cures does not justify either the invocation of evil powers or the exploitation of another's credulity. (C.C.C. # 2117)

15. Why are we commanded to adore God? Because God is the Creator and Ruler of the whole world, and because all we have we received from God. [“Jesus said to him, ‘Away with you, Satan! For it is written, ‘Worship the Lord your God, and serve only Him.’‘” Mt. 4:10]

16. How do we show our adoration of God? By offering Him our humble prayers, and especially by the Holy sacrifice of the Mass.

17. Is the practice of religion necessary, then, for everyone? It is certainly necessary for everyone, and those who say it is enough to lead a good moral life without practicing religion are failing to keep this First Commandment. (What they are saying in their own words is, “My way is better than God’s way!”)

18. The first commandment is also concerned with sins against hope, namely, despair and presumption: By despair, man ceases to hope for his personal salvation from God, for help in attaining it or for the forgiveness of his sins. Despair is contrary to God's goodness, to his justice - for the Lord is faithful to his promises - and to his mercy. (C.C.C. # 2091)

19. There are two kinds of presumption. Either man presumes upon his own capacities, (hoping to be able to save himself without help from on high), or he presumes upon God's almighty power or his mercy (hoping to obtain his forgiveness without conversion and glory without merit). (C.C.C. # 2092)

20. Do Catholics break the First Commandment by having crucifixes and statues in their churches? No, because they do not adore these. God does not forbid the mere making of images, but the adoring of them after they are made: “You shall not bow down to them or worship them.” [Exo. 20:5] Note: In the same Book of the Holy Bible where we find the Commandments, we have the record of God commanding the making of the images of two Angels: “You shall make two cherubim of gold; you shall make them of hammered work, at the two ends of the mercy seat.” i.e., the ark of the covenant. [Exo. 25:18]


21. What is the Second Commandment? “You shall not take the Name of the Lord your God in vain.”

22. What is forbidden by this Commandment? It is forbidden to use the Name of God in any profane or irreverent way, as by cursing and blasphemy.

23. Among all the words of Revelation, there is one which is unique: the revealed name of God. God confides his name to those who believe in him; he reveals himself to them in his personal mystery. The gift of a name belongs to the order of trust and intimacy. "The Lord's name is holy." For this reason man must not abuse it. He must keep it in mind in silent, loving adoration. He will not introduce it into his own speech except to bless, praise, and glorify it. [Cf. Zech 2:13; Ps 29:2; 96:2; 113:1-2] (C.C.C. # 2143)

24. The second commandment forbids the abuse of God's name, i.e., every improper use of the names of God, Jesus Christ, but also of the Virgin Mary and all the saints. (C.C.C. # 2146)

25. What is an oath? An oath is a calling upon God to witness the truth of what we say. “The second commandment forbids false oaths. “Taking an oath or swearing is to take God as witness to what one affirms. It is to invoke the divine truthfulness as a pledge of one's own truthfulness. An oath engages the Lord's name. ‘You shall fear the LORD your God; you shall serve him, and swear by his name.’ [Deut 6:13]”(C.C.C. # 2150)

Example: When a person places his hand on the Holy Bible in a courtroom and testifies to tell the truth, he is making an oath.

26. What is perjury: Perjury is a false oath; calling upon God to witness the truth of something we know to be false.

27. A person commits perjury when he makes a promise under oath with no intention of keeping it, or when after promising on oath he does not keep it. Perjury is a grave lack of respect for the Lord of all speech. Pledging oneself by oath to commit an evil deed is contrary to the holiness of the divine name.” (.C.C.C. # 2152)

28. What is a vow? A vow is a solemn promise made in the Name of God to do something pleasing to Him.

29. What are the things usually promised in a vow? Men and women who enter religious communities usually promise in the form of a vow to live in Chastity, Poverty, and Obedience.

Note: A lay-person, living in the world, should not make a vow of any kind except after careful consideration and with the advice of an experienced priest.


30. What is the Third Commandment? It is, “Remember to keep holy the Lord's day.“

31. Why did God command the Sabbath to be kept holy? Because He completed the work of creation in six days and rested on the seventh day.

“For in six days the Lord made heaven and earth, the sea, and all that is in them, but rested the seventh day; therefore the Lord blessed the Sabbath day and consecrated it.” [Exo. 20:11]

Note: The Catholic Church teaches that six days does not necessarily mean six days of twenty-four hours each, but rather six periods of time of any length. Accordingly, a day could be symbolic of ten thousand years.

32. Why do we keep holy the first day of the week instead of the Sabbath, or seventh day? We do so on the authority of the Apostles. We know the Apostles selected Sunday instead of the Sabbath to hold their Christian meetings, because Christ rose from the dead on Sunday, and the Holy Ghost came down upon the Apostles on Sunday (Pentecost).

“And on the first day of the week, when we met to break bread, Paul was holding a discussion with them...” [Act. 20:7]

33. The Sunday celebration of the Lord's Day and his Eucharist is at the heart of the Church's life. ‘Sunday is the day on which the paschal mystery is celebrated in light of the apostolic tradition and is to be observed as the foremost holy day of obligation in the universal Church.’ [CIC, can. 1246 § 1]” (C.C.C. # 2177)

34. How are Catholics obliged to keep Sunday holy?

34.1 They are obliged to attend Holy Mass on Sunday.

34.2 They are to abstain from doing unnecessary work on Sunday.

34.3 They are to avoid shopping on Sunday.

35. The precept of the Church specifies the law of the Lord more precisely: ‘On Sundays and other holy days of obligation the faithful are bound to participate in the Mass.’ [CIC, can. 1247] ‘The precept of participating in the Mass is satisfied by assistance at a Mass which is celebrated anywhere in a Catholic rite either on the holy day or on the evening of the preceding day.’ [CIC, can. 1248 § 1] (C.C.C. # 2180) (Note: “precept” means “teaching.”)

36. A parish is a definite community of the Christian faithful established on a stable basis within a particular church; the pastoral care of the parish is entrusted to a pastor as its own shepherd under the authority of the diocesan bishop." [CIC, can. 515 § 1] It is the place where all the faithful can be gathered together for the Sunday celebration of the Eucharist. The parish initiates the Christian people into the ordinary expression of the liturgical life: it gathers them together in this celebration; it teaches Christ's saving doctrine; it practices the charity of the Lord in good works and brotherly love. (C.C.C. # 2179)

37. You cannot pray at home as at church, where there is a great multitude, where exclamations are cried out to God as from one great heart, and where there is something more: the union of minds, the accord of souls, the bond of charity, the prayers of the priests. (C.C.C. # 2179)

38. What would excuse a person from his obligation of attending Mass?

38.1 Illness, or the duty of attending the sick.

38.2 A necessary obligation during the hours of the Holy Mass. (Example: The house is on fire or a water line just broke in the house.)

38.3 Living at a great distance from a Church where a priest will be celebrating the Holy Mass. (Note: If a person must walk versus driving, a "great distance" is judged differently. For example, it would not be unreasonable to have to walk 2 miles to Church, or to drive 30 miles to Church. It may be difficult to have to walk 10 miles to Church or drive 100 miles every Sunday.

39. Those who deliberately fail in this obligation commit a grave sin. (C.C.C. # 2181) When you commit a grave sin, you cannot receive the Sacrament of the Holy Eucharist until such time as you have confessed your grave sin.

40. What kind of labour is permitted on Sunday? Any of the following trades that are required to work on Sunday: doctors, nurses, pharmacists, policemen, firemen, 911 telephone operator, prison guards, utility maintenance during major storms, etc... providing their working days cannot be rotated with another employee.

41. Besides attending Mass and abstaining from work, how are we recommended to spend Sunday? We are recommended to spend it in a manner becoming the Lord’s Day; attending an afternoon or evening service in the Church, and devoting some time to devout reading and prayer.

42. Are we forbidden from participating in any form of amusements on Sunday? No. Such amusements and relaxations as are innocent in themselves may be indulged in, so long as they do not interfere with our religious obligations.

Note: When a person drives 100 miles to go to his Summer cottage for the weekend but he will not drive 5 miles to the nearest Church on Sunday morning to attend Holy Mass, this person is breaking the Third Commandment. The Third Commandment is also broken when a mother is willing to drive her son the distance of 20 miles three times a week for his hockey practices, but she will not drive 10 miles to go to Church on Sunday. It becomes obvious that hockey practices are more important than honouring the Lord's Day.

43. If because of lack of a sacred minister or for other grave cause participation in the celebration of the Eucharist is impossible, it is specially recommended that the faithful take part in the Liturgy of the Word if it is celebrated in the parish church or in another sacred place according to the prescriptions of the diocesan bishop, or engage in prayer for an appropriate amount of time personally or in a family or, as occasion offers, in groups of families.[CIC, can. 1248 § 2] (C.C.C. # 2183)

Note: When there is another Church within a reasonable distance, in the absence of a priest at their Church, the faithful are obligated to attend Holy Mass at the other Church. The Liturgy of the Word by a lay person does not substitute attendance at the Holy Mass. In fact, the person who does not attend Holy Mass when another Church is within a reasonable distance, that person commits a grave sin which must be confessed because he can once more receive the Sacrament of the Holy Eucharist.


44. What is the Fourth Commandment? “Honour your father and your mother.”

45. What is ordained by this Commandment?

45.1 To love and respect our parents, and to obey them in all that is not sinful.

“Hear my child, your father’s instruction, and do not reject your mother’s teaching.” [Prov. 1:8] “Children, obey your parents in the Lord, for this is right. Honour your father and mother - this is the first commandment with a promise.” [Eph. 6:1-2] “Let every person be subject to the governing authorities; for there is no authority except from God, and those authorities that exist have been instituted by God.” [Rom. 13:1]

45.2 To respect and obey every lawful authority both religious and civil.

Note: This Catholic doctrine that we are obliged in conscience to obey the just laws of the land is the best answer to the charge that a Catholic cannot be a good citizen.

46. The fourth commandment is addressed expressly to children in their relationship to their father and mother, because this relationship is the most universal. It likewise concerns the ties of kinship between members of the extended family. It requires honor, affection, and gratitude toward elders and ancestors. Finally, it extends to the duties of pupils to teachers, employees to employers, subordinates to leaders, citizens to their country, and to those who administer or govern it.” “This commandment includes and presupposes the duties of parents, instructors, teachers, leaders, magistrates, those who govern, all who exercise authority over others or over a community of persons. (C.C.C. # 2199)

47. The fourth commandment illuminates other relationships in society. In our brothers and sisters we see the children of our parents; in our cousins, the descendants of our ancestors; in our fellow citizens, the children of our country; in the baptized, the children of our mother the Church; in every human person, a son or daughter of the One who wants to be called "our Father." (C.C.C. # 2212)

48. As long as a child lives at home with his parents, the child should obey his parents in all that they ask of him when it is for his good or that of the family. "Children, obey your parents in everything, for this pleases the Lord." [Col 3:20; Cf. Eph 6:1] Children should also obey the reasonable directions of their teachers and all to whom their parents have entrusted them. But if a child is convinced in conscience that it would be morally wrong to obey a particular order, he must not do so. As they grow up, children should continue to respect their parents. They should anticipate their wishes, willingly seek their advice, and accept their just admonitions. (C.C.C. # 2217)

49. The fourth commandment reminds grown children of their responsibilities toward their parents. As much as they can, they must give them material and moral support in old age and in times of illness, loneliness, or distress. Jesus recalls this duty of gratitude. [Cf. Mk 7:10-12] (C.C.C. # 2218)

50. For the Lord honored the father above the children, and he confirmed the right of the mother over her sons. Whoever honors his father atones for sins, and whoever glorifies his mother is like one who lays up treasure. Whoever honors his father will be gladdened by his own children, and when he prays he will be heard. Whoever glorifies his father will have long life, and whoever obeys the Lord will refresh his mother. [Sir 3:2-6] O son, help your father in his old age, and do not grieve him as long as he lives; even if he is lacking in understanding, show forbearance; in all your strength do not despise him... Whoever forsakes his father is like a blasphemer, and whoever angers his mother is cursed by the Lord. [Sir 3:12-13, 16]” (C.C.C. # 2218)

51. Public authority is obliged to respect the fundamental rights of the human person and the conditions for the exercise of his freedom. (C.C.C. # 2254)

52. It is the duty of citizens to work with civil authority for building up society in a spirit of truth, justice, solidarity, and freedom. (C.C.C. # 2255)

53. Citizens are obliged in conscience not to follow the directives of civil authorities when they are contrary to the demands of the moral order. "We must obey God rather than men" (Acts 5:29) (C.C.C. # 2256)


54. What is the Fifth Commandment? “You shall not kill.“

55. "Human life is sacred because from its beginning it involves the creative action of God and it remains for ever in a special relationship with the Creator, who is its sole end. God alone is the Lord of life from its beginning until its end: no one can under any circumstance claim for himself the right directly to destroy an innocent human being." [CDF, instruction, Donum vitae, intro. 5] (C.C.C. # 2258)

56. What is forbidden by this Commandment?

56.1 It is forbidden unjustly to take the life of a human being.

56.2 It is forbidden to take the life of an unborn child.

56.3 Hatred, anger, jealousy, quarreling, excessive drinking are forbidden, because these may lead to killing, or may injure ourselves and others.

57. "All who hate a brother or sister are murderers, and you know that murderers do not have eternal life abiding in them.” [1 Jn. 3:15] “You have heard that it was said to those of ancient times, ‘You shall not murder’; and 'whoever murders shall be liable to judgment.’ But I say to you that if you are angry with a brother or sister, you will be liable to judgment." [Mt. 5:21-2] (C.C.C. # 2054)

58. Since the first century the Church has affirmed the moral evil of every procured abortion. This teaching has not changed and remains unchangeable. Direct abortion, that is to say, abortion willed either as an end or a means, is gravely contrary to the moral law. (C.C.C. # 2271)

59. Those whose lives are diminished or weakened deserve special respect. Sick or handicapped persons should be helped to lead lives as normal as possible. (C.C.C. # 2276)

60. Whatever its motives and means, direct euthanasia consists in putting an end to the lives of handicapped, sick, or dying persons. It is morally unacceptable. Thus an act or omission which, of itself or by intention, causes death in order to eliminate suffering constitutes a murder gravely contrary to the dignity of the human person and to the respect due to the living God, his Creator. The error of judgment into which one can fall in good faith does not change the nature of this murderous act, which must always be forbidden and excluded. (C.C.C. # 2277)

61. Intentional euthanasia, whatever its forms or motives, is murder. It is gravely contrary to the dignity of the human person and to the respect due to the living God, his Creator. (C.C.C. # 2324)

62. When is it permitted to take the life of another person?

62.1 If lawful authority commands it in punishment for graves crimes. Although statistics have proven that the application of the death penalty does not serve as a deterrent to crimes.

62.2 In a just war. A "just war" is normally viewed as defending one's nation against an invasion. Invading another nation is rarely considered as a "just war."

62.3 In self-defense in order to save one’s life, or to save the life of another who is unjustly attacked.

63. Is it permitted to take one’s own life? No. Suicide is a grave sin. We have no dominion over our own life.

64. Suicide contradicts the natural inclination of the human being to preserve and perpetuate his life. It is gravely contrary to the just love of self. It likewise offends love of neighbor because it unjustly breaks the ties of solidarity with family, nation, and other human societies to which we continue to have obligations. Suicide is contrary to love for the living God. (C.C.C. # 2281)

Note: Many "Living Will" are classified as suicide. It is forbidden for Catholics to write a Living Will that would authorize the medical profession to end one's life by deprivation of the basic needs such as oxygen, medication(s), food and water due to a person's temporary or permanent medical condition.


65. What is the Sixth Commandment? “You shall not commit adultery.“

66. What is the sin of adultery? Adultery is the sin of a married person who is unfaithful to his or her marriage vow. The common term used is "cheating" on one's marriage partner. “But he who commits adultery has no sense; he who does it destroys himself.” [Prov. 6:32]

67. Can adultery be committed any other way? “In the Sermon on the Mount, Jesus interprets God's plan strictly: "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] What God has joined together, let not man put asunder. [Cf. Mt 19:6]” (C.C.C. # 2336)

68. Does this Commandment apply to anyone besides married people? Yes, it forbids fornication by unmarried persons, and all actions, alone or with others, of the same or different sex, that are contrary to chastity, decency, and modesty. "Fornication" means sexual intercourse between partners who are not married to each other.

“Do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived; fornicators, idolators, adulterers, male prostitutes, sodomites, thieves, the greedy, drunkards, revilers, robbers - none of these will inherit the kingdom of God.” [1 Cor. 6:9-10] “Now the works of the flesh are obvious: fornication, impurity, licentiousness, idolatry, sorcery, enmities, strife, jealousy, anger, quarrels, dissensions, factions, envy, drunkenness, carousing, and things like these. I am warning you, as I warned you before: those who do these things will not inherit the kingdom of God.,” [Gal. 5:19-21]

69. Do we break this Commandment by sins of speech and of sight? Yes.

69.1 Conversations and stories that offend against modesty are forbidden by this Commandment.

69.2 It is also forbidden to read bad books, or to witness suggestive plays and pictures, or to yield to sinful curiosity of the eyes.

“Blessed are the pure of heart, for they will see God.” [Mt. 5:8] “But fornication and impurity of any kind, or greed, must not even be mentioned among you, as is proper among saints. Entirely out of place is obscene, silly, and vulgar talk; but instead, let there be thanksgiving.” [Eph. 5:3-4]

The various forms of chastity

70. All the baptized are called to chastity. The Christian has "put on Christ," [Gal 3:27] the model for all chastity. All Christ's faithful are called to lead a chaste life in keeping with their particular states of life. At the moment of his Baptism, the Christian is pledged to lead his affective life in chastity. (C.C.C. # 2348)

71. People should cultivate [chastity] in the way that is suited to their state of life. Some profess virginity or consecrated celibacy which enables them to give themselves to God alone with an undivided heart in a remarkable manner. Others live in the way prescribed for all by the moral law, whether they are married or single." [CDF, Persona humana 11] Married people are called to live conjugal chastity; others practice chastity in continence:

There are three forms of the virtue of chastity: the first is that of spouses, the second that of widows, and the third that of virgins. We do not praise any one of them to the exclusion of the others.... This is what makes for the richness of the discipline of the Church. [St. Ambrose, De viduis 4, 23: PL 16, 255A] (C.C.C. # 2349)

72. What are some offenses against the virtue of chastity? The following sins oppose chastity:

72.1 Lust: an intense or obsessive sexual desire.

72.2 Masturbation: the deliberate stimulation of the genital organs in order to derive sexual pleasure outside of marriage.

72.3 Fornication: sexual intercourse between partners who are not married to each other.

72.4 Pornography: Sexually explicit pictures, writing, or other material whose primary purpose is to cause sexual arousal.

72.5 Prostitution: offering sexual acts/intercourse for pay.

72.6 Rape: forcing another person to submit to sex acts, especially sexual intercourse.

72.7 Practicing homosexuality: sexual activity with another of the same sex.

72.8 Common-law relationships: living with and being sexually involved with another person outside of marriage.

72.9 Sodomy: anal intercourse committed by a man with a man or woman or with an animal.

73. What are the offenses against the dignity of the marriage? They are:

73.1 Divorce.

73.2 Adultery.

73.3 Polygamy: the practice of having more than one spouse at one time.

73.4 Incest: sexual intercourse between persons too closely related to marry, such as between a parent and a child.

73.5 Sexual abuse: sexual activity that is deemed improper or harmful, as between an adult and a minor or with a person of diminished mental capacity.

73.6 Partners making no commitment to one another.

73.7 Marriage before a Justice of the Peace, therefore rejecting a Sacramental Marriage.


74. What is the Seventh Commandment? “You shall not steal.”

75. What is forbidden by this Commandment?

75.1 It is forbidden to take what justly belongs to another.

75.2 It is forbidden to destroy or injure the property or possessions of another.

76. Is it ever permitted to take what belongs to another? In dire necessity it is permitted to take what is necessary to preserve life, if there is no other way to obtain these necessities.

77. The seventh commandment forbids theft, that is, usurping another's property against the reasonable will of the owner. There is no theft if consent can be presumed or if refusal is contrary to reason and the universal destination of goods. This is the case in obvious and urgent necessity when the only way to provide for immediate, essential needs (food, shelter, clothing...) is to put at one's disposal and use the property of others. [Cf. GS 69 # 1] (C.C.C. # 2408)

78. Even if it does not contradict the provisions of civil law, any form of unjustly taking and keeping the property of others is against the seventh commandment: thus, deliberate retention of goods lent or of objects lost; business fraud; paying unjust wages; forcing up prices by taking advantage of the ignorance or hardship of another.

100. What is forbidden by this Commandment? All sensual, impure thoughts and desires are forbidden; such things are sinful if they are wilfully and deliberately kept in one’s mind.

101. “Every one who looks at a woman lustfully has already committed adultery with her in his heart.” [Mt. 5:28] “Evil plans are an abomination to the Lord, but gracious words are pure.” [Prov. 15:26]

102. Are involuntary, impure thoughts sinful? No. But we should strive to banish such thoughts as soon as we realize their nature, and turn our attention to other things.

103. The heart is the seat of moral personality: "Out of the heart come evil thoughts, murder, adultery, fornication...." [Mt 15:19] The struggle against carnal covetousness entails purifying the heart and practicing temperance. (C.C.C. # 2517)

107. The sensitive appetite leads us to desire pleasant things we do not have, e.g., the desire to eat when we are hungry or to warm ourselves when we are cold.

110. While the Ninth and Tenth Commandments appear to repeat the Sixth and Seventh Commandments, they refer to thoughts rather than to one’s actions.


111. When someone asked Jesus, ‘Which commandment in the Law is the greatest?’ [Mt 22:36] Jesus replies: ‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind. This is the greatest and first commandment. And a second is like it: You shall love your neighbor as yourself. On these two commandments hang all the Law and the prophets.’ [Mt 22:37-40; cf. Deut 6:5; Lev 19:18] The Decalogue must be interpreted in light of this twofold yet single commandment of love, the fullness of the Law: [129]

The commandments: ‘You shall not commit adultery, You shall not kill, You shall not steal, You shall not covet," and any other commandment, are summed up in this sentence: "You shall love your neighbor as yourself.’ Love does no wrong to a neighbor; therefore love is the fulfilling of the law. [Rom 13:9-10] (C.C.C. # 2055)

112. In conclusion, it should be stated that all sins can be forgiven through the Sacrament of Confession. While many mortal sins hold the penalty of eternal damnation, such a penalty only applies to those who persists in their sins, refusing to strive towards a holy life in Jesus Christ. Those who reject the grace of God, they condemn themselves. Those who strive to be sanctified through the power of the Holy Spirit and make use of the Holy Sacraments of the Church that were instituted by the Lord Jesus, they have a living hope of inheriting the eternal Kingdom of God as sons and daughters of the Heavenly Father.
