Did you watch the video?
Did you hear the part about the annointed King having wealth and power, not spiritual power, money and power and ushering in the end times?
It seemed like prosperity gospel mixed in with some of the 12th Imam cr*p. In other words, creepy and disturbing. Definitely not mainstream.
And quite frankly, yes, people can believe their version of religion ( NOT THE MUSLIMS THOUGH....THAT'S NOT JUST A RELIGION, IT'S A POLITICAL THING AS WELL !), but the rest of us are also allowed to think it weird, peculiar, and/or distasteful.
The operative term is “kings” plural as in all Christians not “king” singular as in one man. My impression, watching the sermon was that they believe that all Christians are kings and that the church will ultimately be so successful that it will help speed Christ’s return. Again bad theology, but I don’t think it is that far out of the mainstream of the amillenial viewpoint.
