They say that it is sufficient to read the bible exclusively, either alone or in small groups at home. But, strangely, through such ‘Bible reading,’ they have reverted right back to the apostate doctrines that commentaries by Christendom’s clergy were teaching 100 years ago…”—The Watchtower, August 15, 1981, pp. 28-29
Isnt that outright Blashphemy and Utter Self Righteousness ? So the Bible (Assuming its Gods word) alone is NOT sufficient , confusing and misleading that they need WT to lead them on the right path.
