I have an off the wall question that I was pondering.
I'm only using the LDS Church in my example because I'm more familar with it, but this can be related to any denomination that require 10% of your gross pay in tithe.
In the LDS Church, in order to get into the highest degree of their heaven you are required to hold a temple recommend (endowment, sealings etc... all require a temple recommend). One the the prerequisites to get a temple recommend is to be a full tithe payer (10% gross income.) So basically you are paying your way to heaven (in my opinion).
Lets say there is a Mormon member, who has always paid their 10%; however now they no longer believe in the Mormon Doctrine and has studied their way out of the church.
What do you think are the chances they could sue the Mormon church for the 10% tithing that they have paid over the years. I understand you can sue anyone for anything now a days, but would someone have a good enough case to win? They church tracks how much you tithe, so they have record and since the tithing is technically NOT a donation, because according to their doctrine it is needed to get a temple recommend can someone sue and win?
I think that based on the fact that in order to get into their heaven they have to pay tithing and since they no longer believe in their heaven, their tithing should be returned.
