We were told by the parish secretary at our old parish that in order to have your name officially removed from their rolls, you must request an official transfer - to another Episcopal parish. Just b/c you want your name removed (i.e. b/c you are no longer consider yourself an Episcopalian and are in fact actively associated with another Christian body) does not mean they no longer count you as being a member. Ours is not an isolated incident of being told this either.
