I got to thinking about this reading the thread about scriptures they don't use (they have a real problem with Jesus.)
Seems they could solve a lot of problems by just announcing that they aren't a Christian religion at all, they're a Jewish sect! They would no longer have to worry about all that stuff Jesus said about forgiveness and love. They could just go Old Testament and be done with it. They could start tithing, going out in service really would be a sacrifice. Everybody would have to make a trip to Bethel (or wherever) once a year and make an offering.
And a I bet about half of them would come out of the meeting talking about what wonderful new light that was.
