Nepotism? Simony? Within the "perfect" congregation ruled entirely by "Holy Spirit"?
My father said one time, "Anyone who says nepotism or money does not influence bodies of elders as to who is appointed is either very naive or outright lying!"
When he said that he was an elder, he was according to rank and file JW's the only elder they trusted, and according to the other elder's he was feared and hated because he didn't rubber stamp everything and he went to bat for the average am ha'aretz. Whether in the congregation or his employment he had the reputation of being in the words of the president of the company he worked for "religiously ethical and honest."
In the congregation I faded from I saw that the only ones appointed over the twenty years I was there were either family of elders, or had been "studied" with by elders.
