“My wife and I both had to sit for Membership examinations with the Eldership of our church prior to being admitted into communicant voting membership.
Should we so desire, however, we can freely leave the church at any time.”
If however when you leave you decide to take a few pews and maybe the altar, the other members just might try to stop you.
I expect that we would only take out whatever we brought in (not counting tithes already paid, of course).
