In my travels across the country, I’ve found this more prevalent in city parishes, as opposed to those in suburban communities. Where I attend daily Mass during the week, the pastor refers to us as his “weekday parish”. In the past there were 3 Masses Monday through Friday. Collection was taken at the 12:20 and 5:30 Mass, but rarely (I think once a month) taken at the 7:30 Mass. Due to a fewer number of priests, he reluctantly had to cancel the 5:30 Masses, so now collection is taken at both 7:30 and 12:10 during the week. I can only remember a couple of times in the last few years I’ve been there, where the pastor has actually asked that people consider making a donation because the money is running low - and he is visibly uncomfortable doing it.
It costs a lot of money to keep a parish open, particularly the costs of the physical plant itself. This church is open all day - it’s wonderfully cool in the summer and warm in the winter. Confessions are heard 6 days a week - and if the times aren’t convenient, all one has to do is call. There are also 2 large Penance Services each year.
It is so comforting to me to know that my “weekday parish” is there and open for me everyday, I have no problem supporting it along with my home parish.
