This does not apply to V2, which changed the words of the sacraments.
V2 sacraments prove themselves as doubtful, because the words changed. This is all the doubt that is required.
YOU say this does not apply, just as if you can. This is all the doubt that is required for us lay people, but for those tasked with actually re/conditionally ordaining, that is not all that is required. I know this isn't the case, but you come across as if a sacrilege is justified in this matter.
You're comparing apples (Traditional sacraments) and oranges (V2 sacraments) but you're falsely applying apple-rules to oranges. Doesn't work this way...except for the new-sspx, which wants to pretend that oranges are apples.
V2's sacraments are "anti-Trent" as Ottaviani said. Trent's protections/guidelines don't apply.
What you don't understand, apparently at all, is the Church owns the 7 sacraments Pax. Period. They are all the Church's sacraments. None of them are the NO's, or prot's, or anyone else's. The sacraments are strictly the property of the Church - period.
The Prots use our sacraments, the NO use our sacraments, and everyone else who is outside of the Church uses our sacraments - and do so illicitly, at times sacrilegiously, but that does not equate to the sacraments always being 100% invalid. You cannot say that, your knowledge of them being doubtful does not reward you with the authority to decide certain invalidity across the board.
This conversation with you reminds me of you being young Roper who wants to ignore and tear down all the laws - that is, until that idea come back to bite him, in this case it's being bitten with a possible sacrilege.
