My former parish was also packed on Sundays, with catholics who had a poor understanding of the GIRM and could not recognize the liturgical abuses that abounded in the Mass served up to them each week. Whereas the priest who dares to preach straight doctrine is often castigated for his reminders. I prefer the narrow path over the super highway.
Only on Free Republic is an empty church more fruitful than a packed church.
I've seen those churches like the one you used to attend, the "super highway" churches. As someone who lost her faith and regained it again, I must say that one of the factors of my lost was these "super churches" -- whose attendees are either 1)zombie-like when they aren't looking for stimulation or 2) an obnoxious combination of Dr. Phil meets cheesy 70s style hippy-dippy guitar playing "Catholic faith communities". They'd walk out right after communion, not evening waiting for the end of the mass. And then they'd run each other over to get out of the parking lot. BUT THE CHURCH WAS ALWAYS PACKED ON SUNDAY!
Like Walker Percy in his days in the wilderness before he converted, I too thought, "if this is salvation, I don't want it."
