In the congregations I have been in there are many long time dyed in the wool elders who were the sons of women of a certain age. Let me explain - must you? Yes.
Mom "finds the truth" (often because a loved one died in the war, or died when she was young and she bought into the nice ladies calling to offer the resurrection hope) sometime between WW2 and Vietnam. Dad is an opposer or an unbeliever.
Little Johnny is indoctrinated by gullible yet firm mother. Little Johnny loves his mommy and follows her into the faith. Daddy is indifferent or mildly opposed and gives the family financial stability although credit often goes to Jah. During the cold war and the threat of Nuclear Armaggeddon the "truth" provides an anchor to little Johnny. He is convinced by 1975 and the generation that saw 1914 not passing away. He becomes an elder in the 1970's or 1980's. He may have gone on to Bethel or been a CO or Special Pioneer.
He is still there now serving away as he goes through his 60's and 70's, 80's and death. His hopes dashed but he knows nothing else and resignedly plods on until he sits in the corner and hands over the reigns of leadership to a younger less stable, less experienced and less/or willing group in their 30's and 40's.
Do you know of any of these?
