I judge JS to be a prophet (black and white…he is or he is not)…based on the fruit of his actions which are not black and white but are a sliding scale of it being good enough for me to tip the scales from False Prophet to True Prophet.
I don’t even have to weigh all the fruit and see to which side the scale will tip. In my mind someone can preach/do 99% bad, but in the 1% truth be acting as a true prophet. “A prophet when acting as such”
There is also the title or status of “prophet” in a church, I would grant “authentic” to the title of prophet if there was in fact an organization that did in reality recognize the person as their designated “prophet.” Someone else that tried to fake authentication or fraudulently pose as the figure head of an organization would administratively be a “false prophet.”
