One thing also that is unsettling is this scenario. There is a large mission in city A. They sing the Liturgy in English and do the Our Father in a few language, sing the Thrice Holy Hymn in a Byzantine Chant, etc.. mix it up, a Russian melody for something else.. It is a culturally diverse parish, but they always sing the propers in the tonal system of the diocese. Now another jurisdiction is opening up shop not even 1/2 mile away. Why? This isn't a "Based on a true story," this is a real situation.
For kicks, it doesn't have to do with any internal parish fighting. It has to do with a ethnic group in the mission that want it to be a slice of "back home," so they're going to build a new church down the road.
Another example is in a western state I observed this. A small mission split in two, because people didn't want to drive 15 minutes to church. These are not poor people. Come to where I live, I don't even get pizza delivered to my house
But here they split a small mission of about 60 people into two factions.
Now there are two full time priests serving 30 people each in different locations, only about 15 minutes apart. Priests aren't exactly easy to come by, and having two priests tied up in two missions because people wouldn't drive 15 minutes, that's not fair to the parishes that actually need a priest.
