jwfacts,
an interesting topic. just to comment on the comparisons to other groups.
the seventh day adventists were a mixed bag on the trinity. while the majority of them in the nineteenth century were non-trinitarian, some were trinitarian (especially their leader ellen white). this is similar to the advent christian church in the usa which russell's group arose from. to this day they have congregations which are non-trinitarian...though most of them are trinitarian these days. so the sda change was not a total change. it was a solidifying into one camp over the other.
true, the worldwide church of god went through a lot of changes in the last couple of decades. it has survived but it's a shell of its former self.
i personally question whether the rank and file witness will be able to celebrate the centennial of christ's return in 2014 without major doubts arising. how the watchtower society responds to this will be very interesting. it's too early to say how it will impact things but i think it could be major.
i remember when i was first associating with the jws the district assembly talk (1966) was "What Has God's Kingdom Been Doing Since 1914?" perhaps a future assembly talk will be entitled: "What Has God's Kingdom Been Doing Since 1966?"
