- NOTE: Here is how the Catechism of the Catholic Church  expresses the current form of the precepts of the Church:
2042 The first precept (“You shall attend Mass on Sundays and holy days of obligation.”) requires the faithful to participate in the Eucharistic celebration when the Christian community gathers together on the day commemorating the Resurrection of the Lord.<Cf. CIC, cann. 1246-1248; CCEO, can. 881 # 1, # 2, # 4>
The second precept (“You shall confess your sins at least once a year.”) ensures preparation for the Eucharist by the reception of the sacrament of reconciliation, which continues Baptism’s work of conversion and forgiveness.<Cf. CIC, can. 989; CCEO, can. 719>
The third precept (“You shall humbly receive your Creator in Holy Communion at least during the Easter season.”) guarantees as a minimum the reception of the Lord’s Body and Blood in connection with the Paschal feasts, the origin and center of the Christian liturgy.<Cf. CIC, can. 920; CCEO, cann. 708; 881 # 3>
2043 The fourth precept (“You shall keep holy the holy days of obligation.”) completes the Sunday observance by participation in the principal liturgical feasts which honor the mysteries of the Lord, the Virgin Mary, and the saints.<Cf. CIC, can. 1246; CCEO, cann. 881 # 1, # 4; 880 # 3>
The fifth precept (“You shall observe the prescribed days of fasting and abstinence.”) ensures the times of ascesis and penance which prepare us for the liturgical feasts; they help us acquire mastery over our instincts and freedom of heart.<Cf. CIC, cann. 1249-1251; CCEO, can. 882>
The faithful also have the duty of providing for the material needs of the Church, each according to his abilities.<Cf. CIC, can. 222>

9 Q: Why does the Church recommend the faithful to assist at the Parochial Mass?
A: The Church recommends the faithful to assist at the Parochial Mass: (1) In order that all the parishioners of the same parish may unite in prayer together with their Pastor, who is their head; (2) In order that the parishioners may participate more abundantly in the Holy Sacrifice of the Mass, which is applied principally for them; (3) In order that they may hear the truths of the Gospel, which Pastors are bound to explain during Mass; (4) In order that they may learn the regulations and notices which are published at that Mass.

11 Q: Why in the First Precept of the Church is special mention made of the Lord’s day?

A: By the words, To fast on the days prescribed, the Second Precept of the Church commands us to observe the fast: (1) During Lent; (2) On certain days of Advent, where this is prescribed; (3) On Ember Days; (4) And on certain Vigils.

24 Q: Why has fasting on Vigils been instituted?
A: Fasting on Vigils has been instituted to prepare us to celebrate the principal Feasts devoutly.
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.
- NOTE: The current Code of Canon Law  states: “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 are bound by the law of fast up to the beginning of their sixtieth year.”
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.”
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

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.
