Mr. Falcon,
just a few thoughts. . . . . . You're on to something. For those of us who truly believed Jehovah had a hand in all of this, the "appointment by holy spirit" belief was a confirmation that, despite our personal foibles, secret sins and unclean thoughts, the God of the universe, who could read us, knew us better than anyone, was overlooking all of that and certifying as a a spiritual man.
As a congregation overseer at the age of 21, I found some of the other Biblical anecdotes unsettling. For example, the concept that each congregation mention in Revelation had a "star" which we were taught was the congregation overseer. As a young man shuttled across the country to become a troubled congregation's overseer, I did not feel like a star. It was easy to see that many in the community who were not even witnesses were more substantial than me.
In the mid 70's I saw positive proof that appointments were not made by H.S. I'll make this as succinct as possible. Two brothers were recommended as elders. The appointment letter from "the slave," appointed only one. The reason given for the non-appointment was simply put: "too young and not long enough in the truth." What the body of elders found curious is that the one appointed was the younger of the two with fewer years as a JW. It was obvious that the Society had made an error. The kicker was that many on the body did not want to question the odd contradiction, citing the holy spirit's role. The real truth was that the one not appointed was of a minority race. Those of the majority race were reluctant to risk their favorite being unappointed somehow and the minority gain the appointment. As the Congregation Secretary(a new position at that time), I circumvented the local turmoil, sending the Society a letter signed by the Service Committee with several specific questions. I was really curious as a true believer in holy spirit appointments how this would all work out.
Two weeks later the "answer" was received form "Mother." A check mark was placed next to the one originally not appointed. No explanation. No answer to our questions. The man the Society had designated as "too young" and "too new" was appointed as was the other man who was younger and newer.
This was proof to me that holy spirit had nothing to do with the appointments.
