The WTBTS is a corporation that owns property and printing presses. People more than 20 years ago used to use the term "The Society" when referring to the religious authority of the Watchtower magazine, and other publications and the writers. Back in 2000 the Watchtower Society split from the Governing body and is no longer the religious authority of the religion and the people within. The Governing Body is referred to as the Faithful and Discreet slave that Jesus said to have appointed, thus the Governing Body is the spiritual overseers of the organization, not the Watchtower Society.
Then there is the CCJW which is not so much of a property and money holder but the Corportation that is more aligned with the religious aspect of matters. That is what runs and operates and directs the congregations. In other words the CCJW is what is referred to as the Branch. The GB communicates to the congregations through the CCJW, not the Watchtower Society; although the Watchtower is still the name of the magazine that is studied on the weekend meetings.
The failings of the organization is what people refer to as the doctrinal changes. I don't see how that is a failing. It is simply as it was said in the AGM, a better understanding. Not being dogmatic about specifics that were not stated in the Bible. Because sometimes an issue is looked at narrowly but later the view is expanded and looked at with a wider scope. It's like a Supreme Court will make a ruling or issued opinion and then later they will overrule it because there are different people in there and different understandings and different views.
Those people were wicked and because they were destroyed in Sodom they are gone; but Jesus said in an metaphor they are not so bad. But then what about these ones such as an 8 year old girl who died in the flood, etc. Why does anyone care? Worry about those alive today and not the ones who died many millenia ago.
I'm not an apologist. I'm a centerist. I think proJW is wrong and I think antiJW is wrong. So what is right is somewhere in between.
