How does Rome view Gerry Matatics now that he has become a Sedavacantist?
Depending on what kind of sedevacantist, they can be either schismatics or heretics. I don’t know enough about Mr. Mattatics position to say which kind of sedevacantist he is. If they are culpable, they are outside the Church, if not, they are in a partial communion lacking full visible unity.
I what respect do you mean by culpable?
