Book 9 explicitly says the coming era is not one of individual registration but of tribal registration. That means heavenly belonging is not imagined as isolated inward belief.
The chapter goes further and ties registration to restored tribe, restored homeland, and even restored sovereignty. In its logic, people need somewhere and with whom to belong, not only something to believe.
This is one of the sharpest places where Unification theology challenges modern spiritual individualism. Heaven is being imagined as a people with lawful belonging, not a private afterlife option.
