Respect at Mass
Some folks head for the door right after Communion. Even more leave as the final hymn is being sung.
It could be in a few cases there are real emergencies that force them to leave early. But in most cases it's too regular to be an emergency, and I've noticed some of the same people doing it week after week.
I consider that disrespectful to the choir that's leading the music, to the priest who's celebrating the Mass, to the community they are a part of - and, most importantly, to God. You can't spend four more minutes with God? Getting out of the parking lot fast takes precedence over the Lord?
I occasionally attend another parish on Sundays. A while back, the pastor made a passing comment about people leaving early. It was clearly an issue he had addressed before, so he didn't dwell on it. But the point was clear.
Since then I've realized when I attend that parish I see very few people leave before the final hymn is over. Some people even kneel back down and say a few prayers. Also, there are not a lot of people milling and talking in the church: They wait until they are in the hall.
It helps when the priest speaks up, leads, reminds. By his words he can help establish a spirit of respect and reverence. He doesn't have to be shrill or beat people over the head. It can be a few reminders. Something in the bulletin. Maybe a homily on behavior at Mass?
And while we're at it - maybe there needs to be more said about not showing up late all the time (would you do that to a business meeting, or to your boss's house?), about dressing properly at Mass (not like you're on the way to the gym or to mow the lawn, or wearing low-cut revealing tops, etc.), or about not sitting there chewing away at gum the whole Mass, or about turning and talking with neighbors every time there's a "break" (Father's praying, or the choir is singing, or the rest of the congregation is on the way up for Communion).
It's God's House. Show some respect. Show some leadership.
