Elders are told by "Mother" that it's better to be keeping the congregation clean and disfellowship than risk keeping a "wicked man" in their midst.
I heard at a circuit assembly that elders weresupposed to err on the side of mercy. (I guess if they feel like it, they will !)
It seems you can get away with anything in the org if you lie enough.
Keeping a clean "appearance" or image is the main thing, don't you know?
It is interesting to see how if they didn't see you cry...they would feel you are not repentant enough
That is just one factor. There are people (like ButtLight above) who went into the JC thinking that honesty and humility would win over their committee. However, there are elders' human emotions involved, as well as whether you or your family are in the right group in the congregation, how often you attend meetings, how many hours counted in the ministry, etc. The claim that "holy spirit" helps guide the elders is patently false, needless to say.
I would never give anybody the satisfaction of attending a JC.
If I had a chance to do it over, I wouldn't go in front of the JC. I would have just handed them a letter of disassociation, or just waited for their phone call saying I was out of there. But at the time, I (a lifelong JW still) was in the clutches of the organization, thinking that somehow God worked through them and so I had to go give some kind of answer. However, midway through that last meeting with those elders when it was clear that the truth of the situation was not the main deciding factor in my case, I saw that the whole thing was a farce.
