To me, the creed is written in a very modern way, like you're trying to explain your theology to someone who follows a different religion. "We believe the Bloodstars influence us." It sounds like you're not sure. The creed of the church should be a strong affirmation of self-evident truths. Things that everyone knows are true. The words "we believe" should be erased from the entire thing. There were other objections I had to it back when it was written, but I can't remember them at the moment.
Anyway, Brance doesn't really believe in the creed, and doesn't pay any attention to it at all. He's confident in his faith, and doesn't need some list of things he's supposed to believe. Those things are for people that don't really understand the Stars.
