The WTBS has always functioned on the assumption that God's Word and Spirit are somehow inadequate and must be augmented with their spin using perhaps, most likely, undoubtly,surely, possibly in explaining bible events.
I have always felt the Bible (2 Tim 3:16,17) which fully equips and the Spirit (John 16:13) which is said to lead us into all truth are also undermined by stating conjecture (revealed truths) as factual especially when making blanket statements, unverifiable such as Jesus 1914 arrival and their 1918 'appointment' as 2 examples.
The leaders bear a heavier judgment in their self assumptions and demanding strict adherence and loyality at all costs for the appearance of an all knowing entity basking in 'divine favor' in a 'spiritual paradise'. This illusion has and continues quite addictive to many.
