No serious researcher today uses the Bible as an authority.
The very reliance on the Iron Age writings incorporated into the Bible indicates an attitude of unquestioning submission. Here is where the fundamental fault lies in giving proper meaning to ancient texts. They were written by the powerful to control the dumb at a time when written language was itself an evidence of authority. Those who believe the Bible are the dumb and fearful who listen in awe to the religious mediators of the day.
Who needs a mediator? No one unless you're trying to settle a dispute.
"Spirit anointed Christian"? A modern post-Watchtower fiction!
The premise that man is sinful is a catchy religious fallacy which has allowed the priests, clergy and cult leaders to flourish financially and therefore wield power like they did in the first century and continue doing so today. There is no such thing as the "144,000 anointed" it is a myth courtesy of the Watchtower cult.
For our own sanity and progress in the world, we must ignore JW teachings and their irrelevant demands and get a proper life based on things which have evidence for their existence not this worthless Watchtower hocus pocus.
