Clergy-penitent privilege is pretty much like attorney-client privilege. There is a lot you can tell your pastor, but some things they legally and ethically have to reveal.
We all know the WTBTS says they do one thing in public and then recommend other action in secret. So did the Catholic Church and other organizations, and now they are paying the price.
I personally think that anyone hiding crimes against someone else’s natural rights from the victim or the community at large, should be held liable as an associate to the crimes. I however don’t think many things should be illegal though, if you didn’t violate someone’s natural rights then I don’t believe it is a strict crime and then attorney client privilege or clergy penitent privilege kicks in where you should be able to confess to “sins” in order to get those laws overturned, or get personal help (eg addiction) from the community.
