It appears the suit is because millions of dollars have been tithed with the expectation of directing it to the needy, when it is alleged to have actually been directed to propping up Mormon businesses. If true, I hope the church pays bigtime!
That may be true but I still don’t see any meaningful differences. I am not talking about doctrine here just the practice of tithing and where the money goes. The RCC has massive overhead and business interests itself. Some tithes go to the needed, some redirected. Unaffiliated or loosely affiliated houses of worship of most faiths often have leaders that are paid, sometimes modestly sometimes quite well, but whom also have full time work. And they all have some kind of overhead expenses. Even if you went to a Buddhist monastery they would have a collection plate (though probably not a lot of peer pressure to donate).
I have no doubt that some LDS church members put enormous social pressure on others to tithe the “proper amount”. So does Scientology in their own way.
As it happens I watched Murder Among the Mormons last night on Netflix. Interesting story how and why it all went down, some of it tangentially related to the LDS church buying and then stashing away various documents related to the origin of their sect.
