I am of the view that the FORM of the Mass does not come under doctrine but falls under disciplinary law and that apart from the consecration and the priest receiving anything else in Mass can be changed. Also in matters of disciplinary law no Pope can bind a future Pope.
How does Quo Primum figure into this. An SSPX guy maintains that the form of the Mass in its entirety falls under doctrine and not discipline and therefore Quo Primum is binding and the Ordinary Form of the Mass is therefore invalid.
I’m not looking for opinions on which Mass people prefer. I am focussing only on whether the FORM of the Mass falls under doctrine or discipline and if Quo Primum is binding or not with regard to the Mass.
Any help on this?
Since you say “an SSPX guy”, I am assuming that you are not speaking of an SSPX priest.
There are any number of people who hold theological opinions (for here, within the world view of the SSPX) who have no theological degree - even as low a level as a B.A., but who hold forth as if they did. And not to make too fine a point of it, but there are people who have a degree in Theology (including some priests), whose coursework is, politely, suspect, and whose opinions do not exactly reflect the teaching of the Magisterium. To which I would add, not all are of the SSPX world view, as I don’t presume anyone would put Father Hans Kung, or Father Curran in that genre.
I can’t speak for the matter of how open-minded anyone within the SSPX world view is (and never mind the wag who suggests some are so open-minded that… well, you know, something might fall out). But in order not to be sucked into a maelstrom akin to Alice’s Wonderland, I would suggest using what my mother used to use. When the “SSPX guy” starts in again, just say “Oh.” Nothing else; not one word more, other than to repeat. It does wonders for untracking chaos.
Getting into a dispute with them is one of the greater time wasters one can engage into.
Other posters have pretty much answered the issue at the base of this, so I will not repeat. But keep in mind that some of us who were taught our faith before V2, were on occasion taught things as if they were doctrine and immutable, and they weren’t. They were disciplinary, and while it was implied, if not stated that they were immutable, it was not out of ill will that such was taught; pretty much most things seemed to be unchangeable. Which is to say, another way, that there was not much local dispute over much of anything. Some have carried forward from that time, and seemingly cannot get their minds around the fact that what was taught, was taught in innocence, but was incorrect in some aspects. I would suspect, from personal experience, that there are a goodly number of supporters of the SSPX who have that background.
