Annual Meeting Report
“Who Really Is the Faithful and Discreet Slave?”
The evidence points to the following conclusion: “The faithful and discreet slave” was appointed over Jesus’ domestics in 1919. That slave is the small, composite group of anointed brothers serving at world headquarters during Christ’s presence who are directly involved in preparing and dispensing spiritual food. When this group work together as the Governing Body, they act as “the faithful and discreet slave.” - [Emphasis added]
Note: Keep in mind that this doctrinal change relies on the same kind of "evidence" that brought us the "Overlapping Generation" doctrine.
