The Watch Tower Society rejects accusations that it is a false prophet, stating that its teachings are not inspired or infallible, and that it has not claimed its predictions were "the words of Jehovah." George D. Chryssides has suggested that with the exception of statements about 1914, 1925 and 1975, the changing views and dates of the Jehovah's Witnesses are largely attributable to changed understandings of biblical chronology than to failed predictions. Chryssides further states, "it is therefore simplistic and naïve to view the Witnesses as a group that continues to set a single end-date that fails and then devise a new one, as many counter-cultists do." However, sociologist Andrew Holden states that since the foundation of the movement around 140 years ago, "Witnesses have maintained that we are living on the precipice of the end of time."
