The bottom line is this: if it's ok to attend the N.O. (even in remote circuмstances) then why are we traditionalists?
3 things to examine on the N.O. Validity, Legality, Morality. Forget the validity question. It's doubtful if it's valid, but let's assume it is.
Is it moral? What's it's purpose? I'd argue that communion in the hand being the sacrilege that it is, makes this "mass" as a whole an abomination and a blasphemous sacrilege, even if one is just "sitting there". Can I just "sit there" and watch a black mass? Can I just be "in the room" at a "gentleman's club" and not sin? I don't think so.
Finally, let me remind you all that when Cardinal Ottaviani wrote his "intervention" (at the request of + Lefebvre) he condemned it in it's "theologically purest" form.
Finally, is it legal? Either Quo Primum is the law or it isn't. There's no question that Benedict firmly stated that Quo Primum is legally in effect, with the 1962 missal as a lawful revision. No one should question this. Benedict also said that Paul VI's missal is NOT a revision of Quo Primum but a NEW missal. Ergo, it is a parallel missal.
But Quo Primum does NOT ALLOW parallel missals, under pain of sin. I quote:
"...and I order them in virtue of holy obedience to say or sing the Mass according to the rite and manner I am presenting currently, ... And you must not, when celebrating Mass, introduce any ceremonies or recite any other prayers, except those contained in my Missal."
The point is that the N.O. was legally created and promulgated. But no one has to use it, no one is forced to use it, and no one CAN use it, under pain of sin. This is the true diabolical genius of the N.O.! A missal was created, legally, but it means nothing! A parallel missal, with no purpose other than to confuse, coerce and destroy!
For 40 years, no traditionalist could make this argument because the question of the legal status of Quo Primum was in "limbo". But this is no longer! For, as Benedict clarified in his "motu" (which is a legal docuмent of the Church), Quo Primum is the valid law of the Church. And it FORBIDS any other missal from being said, or it's a SIN OF DISOBEDIENCE AGAINST THE POPE.
That's why I say that who or who isn't the current pope (if there is one) DOESN'T MATTER. What matters is the CURRENT LAW IN FORCE. And the current law FORBIDS the N.O. under pain of sin.
