I sent them a letter when we became Catholic, asking them to remove us from the parish.

But I bet we're still on the rolls, 'cause we didn't transfer our letters. I don't know of any way to CANCEL your letters!

Most denominations distinguish between active members and members they're simply carrying on the rolls. Nobody wants to purge them, of course. Won't get done.
