Participating in Mass is, I believe, considered celebrating (#2). In fact, as I read #2, it seems that the excommunicate cannot even pray a private Rosary (which is a sacramental)! That’s something I had never thought about.
David:
Only a priest or bishop can “celebrate Mass”.
Canon law is of the temporal authority of the Church. These laws can NEVER nullify or change the eternal moral law, including all the negative and positive precepts. The moral obligation to pray, to worship God, to keep holy the Sabbath cannot be remitted by any law.
It is completely ridiculous to interpret #2 (on sacramentals) to mean that the excommunicate cannot pray the rosary privately.
Your claim that the excommunicate can sit in the pews, but may not “participate” by praying, singing, etc. is baseless. The rule for interpretation of Canon law is stated:
“Can. 18 Laws which establish a penalty, restrict the free exercise of rights, or contain an exception from the law are subject to strict interpretation.”
Since excommunication is a penalty, the Canons applying that penalty are to be interpreted strictly, meaning narrowly. That means you absolutely cannot draw an unstated conclusion, such as that the excommunicate cannot pray during Mass, or cannot pray the rosary, or cannot attend Mass, etc.
But sacramentals (like Indulgences) are exercises of the temporal authority of the Church. The acts are meaningless apart from the Church. If the Church denies sacramentals to the excommunicate, then there is no Grace associated with them.
The excommunicated person may be in the state of grace. And even persons who are unrepentant from actual mortal sin can receive and cooperate with actual graces to some extent. So the idea that grace is denied to the excommunicate using a sacramental is contrary to the mercy of God and the teaching of the Church on grace.
The Canon “to celebrate the sacraments or sacramentals and to receive the sacraments” refers to clerics in the first part “celebrate”, and to everyone in the second part “receive”. Notice that sacramentals is absent from the second part. This means that lay persons and clerics can receive sacramentals, even when excommunicated.
To every poster: Certain questions in theology and Canon law, if answered incorrectly, can do grave harm to the souls of readers. We must all be careful not to jump to conclusions which would place unnecessary obstacles before the path of salvation of anyone.
