"“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.”" jw.org 10th Nov 2012
1919 as an appointment of anybody by Jesus just has not one shred of real proof.
