“What do the speed of the discussions have to do with you or the Catholicity of the SSPX?”
To me their reluctance demonstrates their lack of Catholicity. They are not ready. Part of the Creed are the Councils, and that includes Vatican II. It’s all bundled up together.
“The Motu Proprio acknowledging that the SSPX has been right these many years and that the Tridentine Mass was NEVER suppressed? Or the decision by the Holy Father to lift the excommunications acknowledging that the SSPX clergy are actually, in fact, not excommunicated?”
That they are unwilling to accept Vatican II is evidence that they again, are not ready. All the councils have to be accepted. Not just all save one. They can’t hold out, and say, no, we refuse. There’s no difference here, than between the Chalcedonians and the non-Chalcedonians. Those who could not accept Chalcedon, left and did just as the SSPX did. Some have been brought back into Catholicity after all this time, some have not.
As soon as they cross that step and profess that they believe that the Pope is the head of the Church, then the consequence of this is that the Councils follow. That includes Vatican II.
I had to say the same when I was confirmed. I had to study all of the council decisions, especially from Trent onwards to make sure that I understood them and what the Church taught and believed.
“To me their reluctance demonstrates their lack of Catholicity.”
That’s nice. You sit in judgment rather than the Holy Father?
“That they are unwilling to accept Vatican II is evidence that they again, are not ready.”
What part of a “Pastoral Council” postulates new Dogma? What are you claiming that the SSPX is doing that, in your personal, private judgment, makes them “schismatic”?
