"Your word is a lamp to my foot". All of wt's doctrines are supposed to be originating from that lamp light, the bible. So wt doctrines are filters or lenses (they had a lighthouse once on their cover) interpreting, publishing that altered light. Sometimes wt discovers they installed a wrong filter; Superior Authorities 1929- ~ 1961.
Considering that the original light has such gems as talking snakes to naked, cloned ladies.... what do you expect of the shadow it casts now?
