Wrong. If any "excommunication" were declared, it would be a nullity which I would ignore without any culpability whatsoever. You are really saying that Rome has the power to say whatever it wants to say and can declare someone schismatic who isn't. But you are wrong. It can certainly say whatever it wants to say. But it has no power to make what is right, wrong, or what is true, false. In other words, no pope is supreme against Divine Law. Justice alone can determine the reality of an excommunication--nothing else.

In other words, the Pope can say I am in Schism, but since I know better I am not. You get the prize for the weakest argument since Henry VIII said, "I really really really need this divorce!"

The point is if you recognize it or not, it is real. The Divine Law that is operative is that the Pope has the power to bind and loose, and the Pope has mad it clear the SSPX is not Catholic.
