Hello Sally, welcome to the board.
If your friend really wants to go back, then :
1] He attends the meetings , even though the cong is not allowed to speak to him, and is not supposed to even smile or acknowlege him - and he certainly could not answer up and he has to sit at the very back and leave imediately it ends.
2} After a few months of this,no set limit, he requests a re instatement hearing from the judicial committee .
3] The hearing is set up similar to his disfellowshipping hearing. He is quizzed by three elders regarding his actions and ,most importantly, his attitude now. He has to convince them of his complete and utter repentance and a revulsion for the sin he committed.
4] if they are satisfied, and he convinces them that he really wants to be a faithfull witness, then they agree to it . The cong. gets an announcement at the next meeting that he is re instated and he is back in the fold.Restrictions may applied at the elders discretion.
That is about it
Question?
From what you have read on this board, do you really want him to go back to that narrow minded,rule bound system that only teaches untruths
Be a friend and discourage him from doing it - there is plenty of life outside .
