The Governing Body proclaimed themselves the Slave because they believe themselves to be anointed, or claim to be anointed, and put in charge of Jehovah's organization. The reality of course is that they are just ordinary men charged by other ordinary men to lead a religion.
Small, sad, men who do not know their left from their right. Men who have no spiritual clothes and must rely on their Helpers to blindly lead and point the way.
By the way, the monthly JW Broadcast is late.
