Is assisting at Sunday Holy Mass important and and serious to you…as the Catholic Church teaches? If it is…you have your answer.
Follow your conscience…if it is well formed…in accordance with the teachings of the Catholic Church…if it is not well formed…then follow the Church irregardless of your ill formed conscience. In other words…place your “bet” on “the guaranteed winning hand”…the teaching of the Catholic Church.
For your consideration…and…refresher…here are the five precepts of the Church from the Catechism…note how very few there are…but how very serious they are…“as serious as a heart attack”…also, note the use of the word “shall” in each precept…it is not a “have a nice day” gratuitous word. For example, in aviation…the failure to follow a “shall” precept or edict…means a catastrophic failure to the aircraft and imminent loss of life…like I said…“as serious as a heart attack…or worse”.
CATECHISM OF THE CATHOLIC CHURCH
2041 The precepts of the Church are set in the context of a moral life bound to and nourished by liturgical life. The** obligatory** character of these positive laws decreed by the pastoral authorities is meant to guarantee to the faithful the very necessary minimum in the spirit of prayer and moral effort, in the growth in love of God and neighbor:
2042 The first precept (“You shall attend Mass on Sundays and holy days of obligation and rest from servile labor”) requires the faithful to sanctify the day commemorating the Resurrection of the Lord as well as the principal liturgical feasts honoring the mysteries of the Lord, the Blessed Virgin Mary, and the saints; in the first place, by participating in the Eucharistic celebration, in which the Christian community is gathered, and by resting from those works and activities which could impede such a sanctification of these days.82
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.83
The third precept (“You shall receive the sacrament of the Eucharist 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.84
2043 The fourth precept (“You shall observe the days of fasting and abstinence established by the Church”) ensures the times of ascesis and penance which prepare us for the liturgical feasts and help us acquire mastery over our instincts and freedom of heart.85
The fifth precept (“You shall help to provide for the needs of the Church”) means that the faithful are obliged to assist with the material needs of the Church, each according to his own ability.86
The faithful also have the duty of providing for the material needs of the Church, each according to his own abilities.87
**THE THIRD COMMANDMENT **
Remember the sabbath day, to keep it holy. Six days you shall labor, and do all your work;** but the seventh day is a sabbath to the Lord your God; in it you shall not do any work.90**
2181 The** Sunday Eucharist is the foundation and confirmation of all Christian practice. **For this reason the faithful are obliged to participate in the Eucharist on days of obligation,unless excused for a serious reason (for example, illness, the care of infants) or dispensed by their own pastor.119 Those who deliberately fail in this obligation commit a grave sin.
