The following quote comes from the thread on whether the Sunday obligation can be fulfilled by attending a Nuptial Mass on a Saturday. The author is Deacon John Cameron, a canon lawyer:
It is a very edifying thing to think of how many of our members possess the kind of zealous faith Deacon Cameron speaks of here. Their personal practices of piety go well beyond the minimum and express their great love for God and the Church.
But there is a danger here. It is possible to present those personal preferences as if they were the law itself, causing confusion and discouragement among those whose piety is at a different stage of development. It can also foster scrupulosity.
We should be careful to present the law as the law, and find a different way to encourage our brothers and sisters to a greater love that goes beyond the law.
Some examples of rigorism that I can recall from recent discussions:
The idea that the Saturday vigil Mass can only be attended by those unable for a grave reason to attend Mass on Sunday.
The idea that one should confess face-to-face because it’s more humiliating.
The ever-present headcovering debate.
The idea that any work or commerce on Sunday is a violation of the third commandment.
What examples can you think of? How can we avoid placing unnecessary burdens on people while still encouraging their piety?
