If someone has been on this "board" for several years, of course, the fact that there is governing board of so-called faithful and discreet slaves is irrelevant. But not to people knocking on doors or about to jump ship to join up with them ( of which I was neither myself).
The idea that a slave labors interminably is foreign to Judaean law. It is more in keeping with Roman, Babylonian, Assyrian and (yes) pre-Civil War American laws. Granted, there are organizations that will use terms such as a Servant of the servants of God, but they are of Roman origin. The notion that the Governing Board is citing Biblical precedent or scripture in the form of a parable about a faithful slave for an interminable claim to authority is in contradiction to the notion of service or slavery in Judean society as described by Exodus and Deuteronomy. For that matter Genesis. It's term limited. Other interpretations are literally pagan.
Anyone going door to door in behalf of such leadership is being made a fool.
