*** w09 6/15 p. 22 par. 10 The Faithful Steward and Its Governing Body ***
However, were all spirit-anointed Christians involved in overseeing the preaching work and in preparing spiritual food? No. The apostle Paul tells us: "Not all are apostles, are they? Not all are prophets, are they? Not all are teachers, are they? Not all perform powerful works, do they?" (1 Cor. 12:29) Although all spirit-begotten Christians engaged in the preaching work, only a very limited number-just eight different men-were used to write the 27 books of the Christian Greek Scriptures.

No. All who are anointed with God's spirit are part of the faithful and discreet slave class, but those making up the Governing Body oversee the spiritual feeding.-6/15, pages 22-24.
