I remember back in the '70's, when the CO visited, he stated from the platform that there were people working at Bethel who had been there for many years and who had initially started, not because they were interested in the truth, but because they wanted some means of support. (Not, of course, that they would make good money, but at least have room and board.) Now the Society had gotten wise to them and made all the Bethelites take a written examination on the basic beliefs, and the ones who flunked were dismissed. The CO thought this was something to be proud of, that such people would no longer be tolerated.
At the time I could see that expelling people who had been admitted with the understanding that their labor alone was required, who had been supported for years and were now older and could do nothing else with their lives was wrong. It would have been one thing to test all the newcomers, and not allow someone to start working at Bethel who didn't know the basics, but it was wrong to make this retroactive and expel people who had nowhere else to go - no pension, medical benefits, etc.
Does anyone know anything more about this - perhaps former Bethelites who were there at the time?
