From my perspective Cordelia,
I have always considered the "truth" to refer to a concept that was absolute. For me, "truth" is the real nature of something. The actual essence of reality, free from our distorted perceptions. The watchtower has proven, from its very inception, that they not only have no consistent definition of truth, but they do not even comprehend what "truth" is intented to be. Truth is not a "sliding scale", it does not mutate and wear different masks. It is what it is, reality. The actual state of being, in and of itself. It is what it is, not what 'we want it to be'.......for the JWs, they have proven again and again, the truth is 'what they want it to be'....
Since 1879, they have spread misinformation, false dates, empty promises, lethal medical advice, idiotic sets of rules and regulations and completely and utterly distorted the words of the very prophet they claim to represent, Jesus. From CT Russell, to Fred Franz, they have used charlatans and buffoons to translate the bible to fit their own agenda. They have controlled the lives and thoughts of millions of people while simultaneously building a multi-billion dollar publishing corporation.
There is not even the remotest chance that what they represent is the truth. And if by some bizarre twist in the universe it was the truth, I would rather be dead then exist in the watchtowers perception of truth.
