Link...he HAS to go. Not going is in effect admitting guilt AND showing unrepentance in the Elders' book. I didn't go to my hearing and what happened? I got DFed.
I would do what has already been brought up...
DENY DENY DENY (nobody saw you anyway, so what "two witness" proof do they have?) It's your word against hers.
Point out that nothing was said until you got a new GF.
Blame her accusations on her JEALOUSY.
Do the "false witness" scripture quotes, too.
If you play it right by the time you get done they will be looking to discipline HER and not YOU.
