Traditional theology disagrees, as the Catholic Encyclopedia recognizes. Even an unjust declaration of excommunication must be obeyed.
Believe me, SSPX priests don't lose sleep over worrying about this. They KNOW the so-called excommunication is a nullity.
Believe me, Dr. Martin Luther didn't worry about Exsurge Domine either. He knew the "so-called excommunication" was a nullity.
Luther didn't defend Catholic Tradition, he was a revolutionary--like the Pontiff. The Archbishop drew the line in the sand--this is Catholic Tradition. If you, the Roman Pontiff, oppose it, however much I may revere your office, I am obliged to resist you and defend the faith. I cannot be complicit in establishing a new religion.
"Traditional theology disagrees, as the Catholic Encyclopedia recognizes. Even an unjust declaration of excommunication must be obeyed."
Not if the life of the Church is at stake. All your arguments lose force against this enormity. What's going on is a modernist crisis without precedence. You are using legalisms that can't apply in such an emergency.
