I don't think anyone said it was unreasonable. Although I'm sure "donate what you can" is a bit more specific when push comes to shove.
I don't think so either, but a church/school demanding to see its parishioners' tax info or otherwise conducting some kind of audit seems unreasonable to me.
how do you think the tuition assistance mentioned on your link is administered?
I think needs based financial aid is a little different than a blanket audit/mandated tithe for all students.
ah, it's only unreasonable for people who can afford the school to have their finances audited by the parish.
Yep. Pretty much how any other student aid works.
I think it's unreasonable for a parish to know the finances of every parishioner if there's not really any reason to know. It's invasive and a waste of resources that serves no purpose.
If a parishioner is coming to the church/school and asking for need-based aid, then yeah, the church/school has a reason to take an interest in that person's financial situation.
