I know it's a scam to further the wealth of the church corporation.
The church took the law of tithing, turning it from a voluntary and temporary practice to being tied directly to your worthiness and salvation. Paying money to access god in the temple is a corrupt practice. I find it abhorrent that the church, with over 100 billion dollars, would ask people to pay tithing before their bills. Exploiting the poor and then using their experiences as faith promoting stories is immoral.
Everyone who pays tithing should have their temporal needs ensured, but that’s not what happens.
Tithing is how the church is funded. My parents made the decision to not pay tithing, because they'd rather provide for my bother and me than pay into the church and rely on the church for help. I applaud that decision. However, it kept my parents out of the temple. It kept my father, a return missionary and life-long believer, from being in the room when my brother got set apart as a missionary. This hurt my father deeply, and my brother defended his bishop's decision. Not paying tithing is going to keep my parents from seeing my brother's wedding; he refuses to have two services. In my experience, tithing is a wedge used against families to either encourage conformity or cause exclusion.
