The Watchtower is likely more right than most on these doctrines.
However there is an underlying hidden apostate message in the elusive pursuit of "perfect doctrine" by means of "doctrinal dissection". The false anti-Christ message is that we are put right with God based on finding and following the correct doctrine/s.
By extension we should coerce, condemn and "kill" any who do not believe EXACTLY what we believe - even if we flip-flop.
The results (fruits) speak for themselves. Supremacist self-righteousness and ignorance of the unabridged "good news" about God's undeserved kindness (aka the "gospel of grace"). And also a desperate need to cover up crimes, shield perpetrators, and denounce and ostracise victims.
Neither Paul nor Jesus were preoccupied with these doctrines. Their preoccupation was with the full "good news" which includes God IMPUTING a right, clean, sinless, perfect and familial standing to ANYONE willing to receive these priceless, generous and FREE GIFTS.
It is no accident that Watchtower religionists are ignorant of the "good news" or gospel according to Paul, Moses, Isaiah and Psalms! Consider also that more than half the Bible's roughly 152 references to the "good news" are by Paul! The blind leading the blind indeed.
