People can quote the catechism all they want, but the reality is that there is a difference between what’s grave matter and what’s mortally sinful. Posters here are adopting the position that what’s grave matter is categorically mortal sinful. They are not.
Moreover, even the 10 commandments are not always categorical: killing of others in numerous instances is not sinful.
Ok, TheDoctor, go ahead and hold your tongue… But while you’re at it, could you please forward me that list of church-approved mortal sins? No one seems able to get me that (because it doesn’t exist, and hence the teacher was wrong and needlessly harsh too).
English translation of canon law says that grave sins are to be confessed. If the matter is grave and the action was willful (as is necessary for it to be a sin at all), it is to be confessed:
*
Can. 988 §1. A member of the Christian faithful is obliged to confess in kind and number all grave sins committed after baptism and not yet remitted directly through the keys of the Church nor acknowledged in individual confession, of which the person has knowledge after diligent examination of conscience.
§2. It is recommended to the Christian faithful that they also confess venial sins.
**Can. 916 *
A person who is conscious of grave sin is not to celebrate Mass or receive the body of the Lord without previous sacramental confession unless there is a grave reason and there is no opportunity to confess; in this case the person is to remember the obligation to make an act of perfect contrition which includes the resolution of confessing as soon as possible.
By your logic, because the Church has not published a list of mortal sins, it could be concluded that it is impossible to know what is and is not a mortal sin or impossible to teach what is and is not a mortal sin.
That there is no “list” does not mean the Church has not made it abundantly clear that there is a grave duty to attend Mass on Sundays and holy days of obligation. The Church did so in the documents of Vatican II (so no, they didn’t get rid of that obligation…)
*Accordingly the sacred Council has seen fit to decree as follows.
- By a tradition handed down from the apostles which took its origin from the very day of Christ’s resurrection, the Church celebrates the paschal mystery every eighth day; with good reason this, then, bears the name of the Lord’s day or Sunday. For on this day Christ’s faithful are bound to come together into one place so that; by hearing the word of God and taking part in the eucharist, they may call to mind the passion, the resurrection and the glorification of the Lord Jesus, and may thank God who “has begotten them again, through the resurrection of Jesus Christ from the dead, unto a living hope” (1 Pet. 1:3). Hence the Lord’s day is the original feast day, and it should be proposed to the piety of the faithful and taught to them so that it may become in fact a day of joy and of freedom from work. Other celebrations, unless they be truly of greatest importance, shall not have precedence over the Sunday which is the foundation and kernel of the whole liturgical year. *Sacrosanctum Concilium, Constitution on the Sacred Liturgy, solemnly promulgated by His Holiness Pope Paul VI, Dec. 4, 1963
It is also in canon law:*
**Can. 1246 §1. **Sunday, on which by apostolic tradition the paschal mystery is celebrated, must be observed in the universal Church as the primordial holy day of obligation. The following days must also be observed: the Nativity of our Lord Jesus Christ, the Epiphany, the Ascension, the Body and Blood of Christ, Holy Mary the Mother of God, her Immaculate Conception, her Assumption, Saint Joseph, Saint Peter and Saint Paul the Apostles, and All Saints.
**§2. **With the prior approval of the Apostolic See, however, the conference of bishops can suppress some of the holy days of obligation or transfer them to a Sunday.
**Can. 1247 **On Sundays and other holy days of obligation, the faithful are obliged to participate in the Mass.
Moreover, they are to abstain from those works and affairs which hinder the worship to be rendered to God, the joy proper to the Lord’s day, or the suitable relaxation of mind and body.
Can. 1248 §1. A person who assists at a Mass celebrated anywhere in a Catholic rite either on the feast day itself or in the evening of the preceding day satisfies the obligation of participating in the Mass.
§2. If participation in the eucharistic celebration becomes impossible because of the absence of a sacred minister or for another grave cause, it is strongly recommended that the faithful take part in a liturgy of the word if such a liturgy is celebrated in a parish church or other sacred place according to the prescripts of the diocesan bishop or that they devote themselves to prayer for a suitable time alone, as a family, or, as the occasion permits, in groups of families.*
Now you know…the Church has declared this to be an obligation.
