The position... ( that God may indeed
supercede mathematical equations if God
installed or composed them in the first place)
...can be the opposite of self-referential IF it means that persons living in the world agree they will not attempt to usurp the the rights and privileges of others
unless they can also perform proper miracles
such as exceeding physical laws. Certain persons
might, of course, attempt to pass themselves as Gods by claiming their math skills are remarkable, therefore they should be allowed to deceive the public and slander those who annoy them.
