Here's the benefit of confessing your sins to the Elders, I know how they things work.
1. Five, Ten or Twenty years from now and you make a mistake, your sin is thrown back in your face.
2. The notes taken by the Elders are carried from congregation to congregation, this is not like the Catholic Church who claims to absolve the sins both you.
3. If you are part of the 90%, your sins are going to be told at Parties, with Elders who talk about friends sins behind their back. Your not safe, you will suffer the consequences of your sins forever, elderettes will laugh and giggle for you!
4. Any sins you committ will be compared to the original sins you and you wife made, your never free in this Organization.
5. John Travolta and Tom Cruise have rumors spread that Scientology knew their deepest darkest secrets, that's why they could not leave.
