WTC has always preferred a simple litmus test for their adherents - as Ding expressed. Anything that could lead into a gray area of what is right or wrong is quickly squelched. For example, they don't want to talk about how their disbelief in an immortal soul or an inexhaustible life force conflicts with the resurrection of the real person (this is only one example). They demand simple equations to sift their followers, otherwise chaos could break out.
Universal Sovereignty is the perfect Black v White issue. Give the wrong answer and you are OUT!
