Its based on something deeper by those who set the expectation, not those who abide by it. Again, if one doesn’t know why he’s there, then its an empty gesture. Sure, everyone else may know the reason (lets set that as an assumption here), but the other person who stays because other people expect him to stay, it is fruitless. Unless that person is instructed properly, they will never get it.
No, you are wrong about the other one not meeting the obligation. Because the Church herself doesn’t say conclusively who met it or not. Also if going to Mass is just about ticking that “to-do” list on Sundays to be in Mass, again, its an empty gesture. We do not go to Mass to fulfill an obligation.
I’m not exactly sure why this has to do with anything. The expectation is perpetuated by everyone who meets the expectation. I just said, the expectation needs to be reenforced with proper catechesis, did I not? For some reason, you will not allow the “social expectation” part to get into this at all, even with the added catechesis, and I cannot fathom the slightest, tiniest idea why.
By your way of thinking, this is how it goes:
Johnny rudely leaves mass every Sunday after communion, because he doesn’t know why he should stay. He thinks he has to receive the Eucharist every week. Someone kindly informs him that he does not, in fact, have to receive the Eucharist every week, but that his obligation is instead to come to mass on every Sunday and Holy Day. He accepts this truth.
OK, cool. Does this make Johnny care? Maybe, maybe not. Adding a little statement like, “It’s an expectation that every parishioner attend mass every Sunday and Holy Day,” reenforces the “why” on another level, and has nothing to do with charity or lack thereof.
And, about who met the obligation, how am I wrong? Let me put this a different way. If I have a goal, and I reach 99% of it, I DID NOT MEET my goal. It’s the same way with mass. There is a rule, which states that there is an obligation to attend mass. If you are there for 99% of it, you did not meet your obligation. How can this not be clear? You can’t do something partially then go tell someone you did it; you didn’t. You can’t say you did your taxes on your own if you took them to H&R Block; you didn’t You can’t say you attended mass if you left early; you didn’t.
We DO go to mass to fulfill an obligation! That is very dark thinking.
