They attempt to support their claim of being the FDS in the Feb 2017 Watchtower.
WHO REALLY IS THE FAITHFUL AND DISCREET SLAVE?”
12. Since the Governing Body is neither inspired nor infallible, what questions arise?
12 The Governing Body is neither inspired nor infallible. Therefore, it can err in doctrinal matters or in organizational direction. In fact, the Watch Tower Publications Index includes the heading “Beliefs Clarified,” which lists adjustments in our Scriptural understanding since 1870. Of course, Jesus did not tell us that his faithful slave would produce perfect spiritual food. So how can we answer Jesus’ question: “Who really is the faithful and discreet slave?” (Matt. 24:45) What evidence is there that the Governing Body is filling that role? Let us consider the same three factors that directed the governing body in the first century.
13. How has holy spirit helped the Governing Body?
13 Evidence of holy spirit. The holy spirit has helped the Governing Body to grasp Scriptural truths not previously understood. For example, reflect on the list of beliefs clarified that was referred to in the preceding paragraph. Surely, no human deserves credit for discovering and explaining these “deep things of God”! (Read 1 Corinthians 2:10.) The Governing Body echoes the apostle Paul, who wrote: “These things we also speak, not with words taught by human wisdom, but with those taught by the spirit.” (1 Cor. 2:13) After centuries of apostasy and spiritual darkness, can anything other than holy spirit explain the rapid increase in spiritual understanding since 1919?
14. According to Revelation 14:6, 7, how do angels assist God’s people today?
14 Evidence of angelic assistance. The Governing Body today has the colossal task of overseeing an international preaching work involving over eight million evangelizers. Why has that work been so successful? For one, angels are involved. (Read Revelation 14:6, 7.) In many cases, publishers have called on individuals who had just been praying for help! * The overall growth of the preaching and disciple-making work despite fierce opposition in some lands has likewise been possible only with superhuman assistance.
15. What contrast exists between the Governing Body and Christendom’s leaders? Give an example.
15 Reliance on God’s Word. (Read John 17:17.) Consider what occurred in 1973. The June 1 issue of The Watchtower asked the question: “Do . . . persons who have not broken their addiction to tobacco qualify for baptism?” The answer was: “The Scriptural evidence points to the conclusion that they do not.” After citing several relevant scriptures, The Watchtower explained why an unrepentant smoker should be disfellowshipped. (1 Cor. 5:7; 2 Cor. 7:1) It said: “This represents no effort to act in an arbitrary, dictatorial manner. The strictness really proceeds from God, who expresses himself through his written Word.” Has any other religious organization been willing to rely fully on God’s Word, even when doing so presents a real challenge to some of its members? A recent book on religion in the United States notes: “Christian leaders have regularly revised their teachings to match the beliefs and opinions gaining support among their members and in the larger society.” If those of the Governing Body allow God’s Word rather than popular opinion to guide their decisions, who is really leading God’s people today?
