A very long time ago, there was a family in our congregation whose sister/daughter lived in another state. It was in the days when we were doing those tract distribution campaigns, for those who remember, in the '70's. A special day was set aside for distributing tracts for all Jdubs everywhere. After one day, it was back to business as usual.
A member of the family told me that the out-of-state family member told her mom that her congregation had already got their tracts distributed. Caught in a lie! There are reasons why cults change their terminology and their ways of doing things. One of them is that it makes pretenders trip up from time to time.
If this guy has been masquerading for 10 years, he has somehow been keeping up on what they're doing in his absence.
