Now, I know this is preposterous, in fact totally an unbelievable hypothesis, but what if the GB decided that to go more mainstream and pick up more suckers, sorry, converts, they had received New Light that the basic idea of the trinity was true.
Obviously they could not be as blatant about it so as to say something like the various Creeds say, but I can see a way that they could teach something that was more akin to mainstream Christianity, and would make them seem less wacky-weird in comparison.
How on earth would the old-school dubs react ? it would shake them up so much !
I know this is far-fetched, but I do see them doing something similar eventually, some years down the line, when they are running out of cash. By then the real old-school JW's wil have died off, the ones that are left will not know their arse from their elbow when it comes to doctrine anyway.
All the successful money-making Churches have Jesus as their central figure, and his divinity as a primary doctrine. The GB will want to leap on the bandwagon before it disappears in to the blue yonder, with all the cash on board.
