The difference was there was no Governing Body…but say there was, they did not proclaim this teaching as spiritual food. If you did not believe this, you would not get shunned.
The Watchtower likes to portray failed predictions and teaching as the fault of Jehovah’s Witnesses, but nobody blames the “channel”, the Watchtower, or the Governing Body or Watchtower president of the time. It is a top down organization…they take the credit up top, and put the blame on the bottom.
