1.The interpretation of the bible by its leaders which can not be criticized or the doctrines which these men create, to do so would provoke punishment, shunning and accordingly identified as an evil person.
Would like to add that you don't realise this when you study with them. They tell you if the WBTS has got anything wrong they will change it. But they don't tell you WHEN they'll change it (like never or not until it suits them).
Also they don't tell you that if YOU CORRECTLY identify they have got something wrong and inform them, YOU will be ignored because it is not your position to blow the whistle. If you do so you will be accused of being another channel to FDS. Even if the information you are pointing out is from the Bible itself. GB of WBTS trumps Bible.
