The Governing Body in recent years has described itself as the "spokesman" and "representative" of the FDS, though it apparently never seeks the view of those on whose behalf it speaks. Nor, indeed, did the Governing Body ever seek the permission of the FDS to become its spokesman. (This, of course follows the pattern of Judge Rutherford, who sacked the majority of the Governing Body (board of directors) in 1917 because it tried to stop him publishing a personal opinion he believed was "new light").
The July 15, 2010 WT said doctrinal development was the role of a select few members of the FDS: "When the time comes to clarify a spiritual matter in our day, holy spirit helps responsible representatives of 'the faithful and discreet slave' at world headquarters to discern deep truths that were not previously understood. The Governing Body as a whole considers adjusted explanations. What they learn, they publish for the benefit of all."
A 2009 article served as probaby the biggest slap-down for any uppity members of the slave class who thought they atually should have a role in dispensing God's "new light". In it the Watchtower said: "They do not believe that their being of the anointed gives them special insights beyond what even some experienced members of the "great crowd" may have. They do not believe that they necessarily have more holy spirit than their companions of the 'other sheep' have. They do not expect special treatment; nor do they claim that their partaking of the emblems places them above the appointed elders in the congregation." (""The faithful slave and its governing body", The Watchtower, June 15, 2009, pages 23-24) In other words, members of the FDS may think they are part of God's channel, but they'd better just shut the f*** up and obey their "spokesmen".
And yet, consider this: in the April 15, 2011 article, "Do You Discern the Evidence of God's Guidance?", the WT declared that the slave class appoints overseers in the Christian congregation. (p. 4) It directs the preaching and distributes spiritual food through articles, convention talks, letters and messages from travelling overseers (p.4,5). And, as the final paragraph of that article points out, survival into the new world depends on "humble willingness to follow God's direction" through the directions of the slave class. Obey the slave class or die.
All in all, quite a lot of contradictions that the average JW will ignore: the FDS (a) has powers to appoint overseers and is used by God to reveal new light, but (b) is never consulted and members of it are not permitted to express their view if they see things a different way.
