This idea about not permitting resignation is absurd. Of course and elder or ministerial servant can resign if they want!
Local elders can state they do not accept the resignation, but so what? What are they going to do, prop the man up on the stage with a broom stick and play a prerecorded discourse for his next talk assignment? Come on people! The part about local elders not accepting a resignation is no more than local elders voicing a strong recommendation that the WTS should send back encouragement to the man so he will change his mind. It’s no more than that.
The part about the WTS approving a resignation has only to do with whether the WTS wants to try and talk the man into continuing or when an announcement is made of his deletion should an attempt to retain him fail to materialize or fail in its attempt.
Prisila, I wish you and your husband all the best!
