No one denies that the Pope said what he said and can force the issue legally. But, that said, it can't make the declaration morally effective. In fact, the so-called excommunication mentioned in the motu proprio is strictly pro forma and may be ignored without sin--and is. It has absolutely no moral force. Believe me, SSPX priests don't lose sleep over worrying about this. They KNOW the so-called excommunication is a nullity.
It is similar to a married person getting an annulment legally, but having no just grounds for it. The annulment is recognized, but it has no moral effect. In fact, such a person would still be married in the eyes of Heaven.
And by the way, stop shouting. It doesn't make you right.
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.
