Jemimah:
Also having served as an elder and sat in on a few committees, and then having been DF'd myself, I think I have a unique perspective to offer on this issue. Here goes:
In all the committees I sat on, the only reason the person was there was because they had 'confessed' some serious sin. Usually, these persons were considered 'weak' by the BOE. If they weren't repentant about the sin, why did they 'confess' and face a committee? The ones who didn't care what we did or said, usually didn't meet with us, anyway. Case closed. I always wondered, 'Why are we thinking about DF'ing this person when it is so obvious that they need help and support, not 'the spritual axe.''
I'm sure you've heard the old saw, "They need to be taught a lesson, and this is the only thing that will wake them up." Hogwash! Cutting someone off from their family and support structure really teaches them a lesson all right. In almost every case of DF'g in my 22 yrs in the JW's, it did more harm than good. The DF'd individual never recovered from the humiliation it caused. And let me tell you, it is the most humiliating thing to have to come into the KH and sit in the back and ignore people you thought were your closest friends, ["Closer even than a brother."] And have them ignore you like you were an invisible ghost. To get reinstated, you have to grovel and whine like a baby to even to get a hearing.
In one case, a brother had been DF'd by an out of state cong, after 2 or 3 yrs, the guy applied to us for reinstatement. We recommended it to the other cong. Guess what? No go! "Not enough time" Here this poor guy was in our cong, hadn't been anywhere near the other BOE for years and they knew better than we did! So, he writes the WTS in Brooklyn, lo and behold! two months later here comes a letter from the BOE in the other cong, 'We have considered Bro. 'Bad Guy's' letter for reinstatement and have decided to reinstate him.' If the guy hadn't got their 'bags' in a wringer with the CO and DO, he would still be waiting for reinstatement.
In a nutshell, the Judicial Arrangement is full of @##!. It is impossible for imperfect men to render a perfect decision. It causes more problems than it solves; and, it is heartlessly administered by the untrained and underinformed. In those 22 years, I never saw a case where the cong needed to be 'protected'from an individual who had come to the BOE with the problem. Most of the time, the 'practicer of sin' had quit attending the meetings and didn't want anything more to do with the cong. So why DF them? Gotta keep things 'clean.'
You are quite right to be questioning the Judicial Arrangement, it is just what some of the other posters have called it. Look at it from the other side of the fence and you will gain a new insight.
Good Luck!
