I always took the line, after reading the first few books, that Kellhus was really a savior, but subsequent readings and Scott's own comments have made me doubt that. He has said multiple times that the Dûnyain are the illusion of our modern method of thought.
The idea that the world could be mastered, especially Earwa, is flawed. While Moë wants Kellhus to believe that nothing violates the principle of before and after, we actually know that this is false, a la the White-Luck Warrior. Or at least, so we are led to believe.
In the end we are fed some pretty contradictory stuff and really none of our "sources" seem very reliable. I think this is Bakker's point though, which is echoed in his blog posts about "winning the magic-belief lottery," that everyone seems to know exactly what is going on, but in reality they are all probably just seeing things as they want to.
I've always had a sense that what we are in for a big reversal in the end, that where the text seems to be leading us is not the path that will actually be the "true" one. Or maybe his point, that there won't be a "true" path...
Well, that's a lot of rambling, I don't know that I've made any real point though...
