They argue that the sentence of schism and excommunication pronounced against them by the Archbishop of Tyana, the Apostolic Delegate in Constantinople, was unjust, and consequently void of strength and influence ... These novel arguments were wholly unknown and unheard of by the ancient Fathers of the Church ... The Jansenist heretics dared to teach such doctrines as that an excommunication pronounced by a lawful prelate could be ignored on a pretext of injustice. Each person should perform, as they said, his own particular duty despite an excommunication. Our predecessor of happy memory Clement XI in his constitution Unigenitus against the errors of Quesnell forbade and condemned statements of this kind. (Bl. Pius IX, Quartus Supra)
The bottom line is this:
"Can. 1321 §1 No one can be punished for the commission of an external violation of a law or precept unless it is gravely imputable by reason of malice or of culpability."
This important canon is based on Divine Law which states the innocent must not be punished. The defense of Catholic Tradition was an act of sanctity and was not culpable. It was certainly not an act of malice.
