Jan, it's an insular community that revolves around devotion to the organization and its leadership. It is drummed into your head that serving the organization is a privilege, and for most people that happens at the congregation level. And for men, the long path to becoming a ministerial servant --and eventually an elder-- often begins with small privileges like reading the paragraphs during the weekly book/magazine study, saying the opening/closing prayer, and handling microphones. These are visible signs of devotion and also a sign that you are on the right track to gaining those important positions of 'service.'
I can't describe how proud I felt to be named a ministerial servant, even though it came just before I began my long, slow fade. By the time it happened, I'd been conditioned to see it as a very high honor. And even now, so many years removed from it and from the organization, I still feel some sense of value from having been named one. That slow and constant conditioning stays with us for a long, long time.
