For the first time in the history of the world on July 26, 1931 at a convention in Columbus Ohio, Joseph Rutherford made the announcement that true worshipers of God need to be called Jehovah's Witness. Up till that time no one was aware of or used that special, unique and holy name to identify themselves.
What an amazing revelation Jehovah gave this faithful and discreet slave !! The Judge now newly crowned holy heavenly king and priest urges all mere mortal humans on earth to drink up. Why? Because in heaven there is no beer that's why we drink it down here.
Poor judge no more drinky drinky.
