I don't understand why a sedevacantist (well known, or otherwise) would care to weigh in on the Sr. Wilhelmina situation.
After all, the conciliar church, to the sedevacantists, is in no way Catholic. They may as well weigh in on what is happening in the lutheran sect or the baptist sect, or any other non-Catholic sect. Why do they focus so much on the conciliar church, which they believe to be non-Catholic? Is it because many traditional non-sedevacantists do not accept that the conciliar church has apostasized? The sedevacantists tend to believe that the Catholic Church resides primarily in sedevacantist chapels. So why care at all about non-Catholics?
