noitallmr: no i am sorry to tell you but you are wrong. 1. no godol is hashems mouthpiece. at least not since teh churban bayis sheini. nevuah is dead, unless your godol to whom you refer is a women, a child or mentally retarded. they still get nevuah.
and 2. i absolutely do not have to listen to any rabbi alive or dead, if my rabbi, whom i have picked to guide me through life tells me so! this is a fact, not a feeling, or a thing i w=once heard somewhere. this is halacha, you pick a rov and follow, vezeh hu!
