Your "sins" are between you and Auros.
I'm personally against private RP between two people in the form of tells. I just don't see the point of it if it's not for everyone to read.
If you need to get something off your chest - tell your cat, your dog, your parents, your bestfriend, or your RL priest.
Now, if you happen to know of someone else who has been breaking spiritual law...then that might be something the Inquisition might like to know about...
As far as advice goes - just ask your respective Bishop on your Clan's forums in their Church thread. If they don't have one, petition your Clan leader for one. If you're part of the Royal Demnse, you'll just have to wait until an Archbishop is appointed...or post it here, and be prepared to get about 5 different responses.
