Dear Gary Neal, the following from the article about the 2012 AGM appears on the official site JW.org :
"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."
Who Are the "Domestics"?
Jesus said that "his domestics" would receive "food at the proper time." All genuine followers of Jesus are fed by "the faithful and discreet slave." Therefore, all of Christ's disciples-both individual anointed Christians and members of the "other sheep"-are "his domestics."
