Down yonder, a reader asks:
"…the precept to attend Mass is abrogated."
Why ?
Because people would resist and resent it if they were forced to go to church two days in a row. (And it is more of a hassle on holy days since most parishes try to get away with a smaller number of Masses than on Sundays, meaning that the parking lots are more crowded and the people are often unsure when those Masses will be since the usual schedule isn’t being kept.)
People will put up with that for Christmas (like this year), but they’ll either resent it or won’t come other holy days.
That’s awful un-pious, of course, but then this is a fallen world, and that’s just where American society is right now.
Still, we have about 28% regular Mass attendance among Catholics here, which is not only better than a large number of developed countries but (contrary to popular impression) better than church attendance by Protestants here (they typically show up at church about 25% of the time).
Note that I’m not endorsing the abrogation of the need to go to Mass tomorrow, I’m merely explaining it.
A counterargument could be made that if the Church expected more out of people by way of piety that they’d rise to the occasion and act more pious. That’s certainly true in some ways, and one well might argue that this would be the case here.
