I agree that many of the r & f are so rule- bound that they are afraid of doing something wrong , so they turn away in uncertainty.
In my last congo a family let it be known that they were "taking a break from the Truth", in other words left but never d/a'd . A friend of ours, an elderly lady fairly new , said she had been told by Sister Matriarch Knowall that she should not speak to them anymore. We put her right on that.
