Do Gulenists believe Fetullah Gulen is the messias?

Gulenists says always that Fetullah Gulen is the big Mahdi and/or Messias. They even say that he is both and are not shamed to say that Jezus/Isa is only appearing to Fetullah Gulen and his surroundings and is taking orders from him. They do say also the opposite, that he is the expected messias and that the big Mahdi is one of in his surroundings.
