Actually, the particular threat I was thinking about came because a family wished to move to another church after the Church failed to remove a known pederast. They were told that they did not have "permission" and would not be allowed to attend the other church. I believe that they have now found a better, Protestant, church that actually believes 1 Co 5. Do you have any proof for this assertion? There is nothing that stops someone from switching churches. It happens all the time. What are they going to do, lock the doors?
