The Organized To Accomplish Your Ministry book goes onto into it doesn't it?
That book is mandatory reading pre-baptism. But yes, the whole disfellowshipping thing is glossed over. You think with something so potentially devastating to a person's life as the d/f arrangement is they would make people sign a contract or something. Just to emphasize the seriousness of it.
If congregation "cleanness" is such a good thing why hide it?
