Development of Jehovah's Witnesses doctrine

The doctrines of Jehovah's Witnesses have developed since publication of The Watchtower magazine began in 1879. Early doctrines were based on interpretations of the Bible by Watch Tower Bible & Tract Society founder Charles Taze Russell, then added to, altered or discarded by his successors, Joseph Rutherford and Nathan Knorr. Since 1976, doctrinal changes have been made at closed meetings of the group's Governing Body, whose decisions are described as "God's progressive revelations" to the faithful and discreet slave. These teachings are disseminated through The Watchtower, and at conventions and congregation meetings. Most members of the denomination outside the Governing Body play no role in the development of doctrines and are expected to adhere to all those decided at the Warwick, NY headquarters. Jehovah's Witnesses are taught to welcome doctrinal changes, regarding such "adjustments" as "new light" or "new understanding" from God and proving that they are on the "path of the righteous".

Some core beliefs of Jehovah's Witnesses have remained unchanged throughout the group's history. Certain doctrines, particularly relating to biblical chronology, were based on what Russell called a "venerable tradition" that he conceded was not directly confirmed by facts or scripture, but "based on faith". Watch Tower publications claim that doctrinal changes and refinements result from a process of progressive revelation, in which God gradually reveals his will and purpose. Watch Tower literature has suggested such enlightenment results from the application of reason and study, the guidance of holy spirit, and direction from Jesus Christ and angels. Rutherford spoke of spiritual "lightning flashes in the temple", the Society claims its doctrine of the "great crowd" and "other sheep" were "revealed" to "God’s earthly servants" in 1935, and Witness literature has also described sudden changes in doctrines as "flashes of light" given by God through his holy spirit. A 1930 publication claimed God used "invisible deputies" and "invisible angels" to pass his "messages" to The Watchtower, although The Watchtower told Witnesses it was not necessary for them to understand how this took place. A 1973 policy change to disfellowship tobacco users was explained as a decision that "Jehovah has brought to the attention of his 'holy' people".
