All of that could be a cause for ridicule, but there is a seriously sinister side, at the human level. Each time a new light is switched on, the organization demands lock-step acceptance. All minds have to switch over, whether a person agrees or not
It's the human cost of these decisions from the high and mighty GB. How does the woman I knew in my old congregation cope with the loss of her seventeen year old son in a car accident who could have lived if he'd had a blood transfusion? New light about blood fractions doesn't help her.
How does my sister cope with the thought that she could have had IVF and possibly have grown-up children now, even grandchildren. Instead she has an empty house because IVF was forbidden as the discarded embryos were considered to be 'murdered'. New light saying it's a conscience matter now doesn't help her and I can tell you she has not coped.
