Oh ,I certainly remember the 1975 fiasco ,when tey tried to palm it off onto over zealous bros, running ahead of themselves .
As for the Superior Authorities they first taught that it was the worldly govts /authorities etc ,then they had new light and went with Jehovah God and Christ Jesus as the Superior authorities ,then lo and behold more new light flashed and they reverted back to the World Govts and authorities .
You can`t make this stuff up ,how JW`s can flip /flop from one extreme to another .
