I prefer to let Bishop Sanborn explain why cuм ex is moot:
Your contending that it's "moot" completely misses the argument, as usual. I never said that it wasn't legislative ... just that there are elements / aspects of divine law within it as premises, particularly the rejection of convalidation by UA.
In any case, I didn't know you've suddenly become a follower of Bishop Sanborn. He would denounce your ecclesiology as manifest heresy (and rightly so).
