This is where the entire epic behind its claims begin to crumble. The organization does not claim to be a church; in fact, you can be thrown out of the outfit for even attending a church! Yet it's clear that Jesus organized a church and that he gave keys of authority to his apostles to bind, seal or affix on Earth, and that it would be recognized in Heaven. Or these keys could, conversely, loosen on Heaven or Earth. That meant their ordinations and baptisms would be binding and that when they cut people off for apostasy, that also would be recognized in Heaven.
The church had specific offices. Bishops, priests, elders, teachers, deacons, apostles, prophets and others, yet the WTB&TS -- a publishing firm -- has not bothered to even claim these keys. So how can it cut off, or disfellowship, people if it lacks these keys? Or if it does have them, how did they come by them? Who conveyed them? Who received them? If they aren't relevant, why does the Bible mention them?
How can a manmade organization acquire authority that anciently was conveyed by those who had authority?
If I were a JW, I'd certainly want to know these things, especially if I were going to listen to a Governing Body that claimed to speak by and through the power of the Almighty, I would certainly like to know whereby their authority came. If the organization is the Church of Jesus Christ, for Jesus said that upon this rock he would build his church, then it can't be the work of man. And so far the claims of the Governing Body are anemic at best. In the mouth of two or three witnesses shall every word be established, and so far the GB has failed to claim even one word from God, or an angel, or from Jesus Christ.
