Rorate noted that the Church has been extremely schizophrenic on the last bullet point. To be sure, it's not ideal to fulfill one's Sunday obligation at an SSPX chapel. Whether it fulfills the obligation or not seems to depend on whoever happens to be on duty at PCED the day inquiries arrive.
The SSPX is an unusual case. Juridically they are not in schism, though they may be declared formally schismatic if they consecrate new bishops before they are fully regularized in the life of the Church (and Mnsgr. Fellay et. al., aren't getting any younger.) It's bizarre to hear so many progressives gravely pronounce "They are being disobedient to the Holy Father," before they get back to work writing op-eds about how the Church is wrong to oppose contraception and gay "marriage." Likewise, a certain priest blogger for whom I have enormous respect sometimes writes pieces where he urges the SSPX bishops to crawl on their hands and knees across St. Peter's Square and kiss the pope's feet with much sobbing and wailing until he fully reinstates them. One wishes a considerable number of bishops who are ostensibly in full communion with the Church would do likewise, begging God and the Holy Father to forgive them for transferring child abusing priests from parish.
Thanks in large part to Pope Benedict XVI, the SSPX no longer has a monopoly on the Traditional Latin Mass. Traditionalism may have focused on the liturgy when it began, but Traditionalism is much more than the Mass. Likewise, Traditionalism is no longer bound up with the fate of the SSPX which is a good thing in my view. To be a Traditionalist is to believe that the old Mass is a positive good which formed countless saints, martyrs, Doctors, confessors and popes, and should not merely be preserved but actively promoted as a means to renew the life of the Church. To be a Traditionalist is to believe that the lives and writings of the saints are the most helpful means for an active healthy spiritual life. Traditionalism means not being blind to the spirit of compromise and muddleheadedness that has pervaded the Magisterium for the last fifty years, nor the failures of leadership from the hierarchy or their actions which deviate from official teaching. Traditionalism means agreeing that the Church was more successful in her mission and her members more faithful then than they are now.
