You are not blaming God! You are blaming them for assuming the role and authority of prophet, while history shows otherwise.
In fact you are saying they don't follow the bible. Is this strange? No. The entire nation israel left God over and over (according to the bible). Surely if an entire nation can fall to apostacy so can a human organization. claiming to be His organisation proves nothing. It just adds to the acusations against them. The sit on the chair of moses so to speak, just like the pharisees.
