“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.”
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.”—John 10:16.
When Does Jesus Appoint the Slave “Over All His Belongings”?
Jesus said that the “master on arriving” (literally, “having come”) will appoint the slave “over all his belongings.” When does the Master, Jesus, arrive? The expression translated “on arriving” is a form of the Greek word er′kho•mai. Verses 42 and 44 of chapter 24 translate a form of er′kho•mai as “coming.” In those verses, Jesus is referring to his coming as Judge during the great tribulation.—Matthew 24:30; 25:31, 32.
Jesus’ appointment of the “slave” over his “belongings,” then, must also be a future event. He will make that appointment during the great tribulation.
What Are Jesus’ “Belongings”?
Jesus said: “All authority has been given me in heaven and on the earth.” (Matthew 28:18) Jesus’ “belongings” thus include more than just his earthly interests. They include the Messianic Kingdom.—Philippians 2:9-11.
Consequently, Jesus will reward “the faithful and discreet slave” by resurrecting the individual members of that group to heavenly life and by giving them royal authority over all Christ’s belongings in heaven and on earth. This is the same reward promised to all faithful anointed Christians.—Luke 22:28-30; Revelation 20:6.
