A pivotal point in the early 1950s was Hayden C Covington's coup in suddenly converting the Watchtower Society to a religion and appropriating relevant religious organisation privileges via the use of the then publication: "Defending and Legally Establishing the Good News" (sic - actually "Defending and Legally Establishing the Watchtower religion").
Now Watchtower followers have the dubious distinction of being totally ignorant of the "good news" whilst spending a billion hours a year door knocking supposedly as "publishers of the good news". Just ask the next door knocker to explain the "good news according to Paul" from the heart! Their ignorance is not an accident - more than half the Bible's 152-odd references to the "good news" message are by Paul, who had left religion to follow Jesus instead!
