Been there, done that - back to 1988. No big deal.
There will always be a remnant.
I would argue that it is a big deal. The beauty of the post-Summorum Pontificum era was that the TLM was blossoming within regular diocesan parish life. This was and is intolerable to Bergoglio and his minions, and they’re taking it away. I don’t have problem with the SSPX per se, and I think Abp. Lefebvre was a great hero and saint. The SSPX have an important role to play, but it bothers me to think of the TLM confined and quarantined to the SSPX ghetto. And that seems to be Bergoglio’s m.o. Why is he meeting with the SSPX but not the Ecclesia Dei groups? It wouldn’t surprise me if he’s trying to use the SSPX to subsume the Ecclesia Dei groups and the diocesan TLM faithful.
