Some of the recent changes made me think that they are slowly moving towards the mainstream. After so many years of such strict orthodoxy, they cannot embrace mainstream Christianity all at once. But they can begin to move in that direction a few bits at a time. Moving Jesus into a more prominent position would make sense in that context, especially if it is combined with the idea that the GB is fallible and can make mistakes.
The idea of putting the GB in a truly subordinate position to Jesus would be fairly radical, but also a concept that the rank-and-file could accept. Especially if it means a gradual lessening of the 'obedience to the GB' policy. I'm not sure they can go all the way in that direction without leading the rank-and-file to wonder why they don't just go to another church. So I might be on the wrong track. Still, it will be interesting to see if any more changes are made in the near future.
