technically catholics are supposed to tithe 10%. again, that's just a suggestion, not a hard and fast rule. Heck, a lot of catholics don't even go to mass.
the difference is that that money paid to the catholic church isn't buying you anything but a nicer church and helping pay for whatever churches need to run. in scientology the charge is required and it's supposed to buy some form of salvation.
The way it works with scientologists, if you dont have the dough, you dont get to go.
