Matthew,
Like most SSPX trads, you describe the Novus Ordo Missae as bad, not good, troublesome, problematic, defective, wrong, dangerous, etc. These words betray an underlying fault of looking at the Mass as it relates to us, as it relates to man, and not looking at the Mass as it relates to its object, God.
I hold, and will defend this position, that the Novus Ordo Missae is a sacrilege, and in the objective order a mortal sin. And that it represents an evil that is worse than sterilizing oneself or abortion, for the simple reason that sins against the first and second commandments (directed squarely at God) are more heinous than sins against the fifth.
Most Catholics who hold your position do so because they have not a clear idea of what the Mass is. Whether they admit it or not, they imagine that men may worship God as they please, rather than being bound by the first commandment which decrees that we must worship God as HE pleases. We are the creature, He is the Creator. He has absolute domination over us, and we have no right whatsoever to decide how we will adore His Infinite Majesty.
The true Mass was given to us by Christ Himself, grown and developed organically over time under the guidance of the Holy Ghost and the care of the Church, and is a perfect, pleasing, spotless and immaculate sacrifice, a fitting act of adoration and worship of the most Holy Trinity. It is, literally, God giving God to God.
The Novus Ordo Missae is a creation of man. It is not simply man telling God that they will adore Him as they please. It is, in reality, man telling God that we will worship man in place of God. The purpose, the whole reason for its existence, is to replace the true Mass, to bring to an end the worship of the True God. You are, I'm sure, aware of the numerous "problems" of the Novus Ordo. I will not labor through that list here, but have you considered how and to what degree those "problems" are offensive to God? We have whole books written about how they're offensive to Catholics, but few consider how the Majesty of God is offended by these "problems". Add to that the fact that each time the mockery is performed, it is a violation of the standing law of the Church (Quo Primum), and by that fact alone constitutes a sacrilege of unimaginable proportions.
Holding the position that the act, the event, of the Novus Ordo Missae being evil and a sacrilege, does not lead to inescapable conclusion that there is "nothing Catholic at all in the Conciliar Church." Rather, the fact that it was given to us by the very shepherds of the Church makes its sacrilegious nature all the more poignant. It is the difference between the Babylonians creating a false rite and the priests of the Mosaic Law creating one. The latter example is far more odious than the former. Does the fact that the Hebrew priests devised their own false worship, their own "Novus Ordo", demand we take the position that there was nothing of the worship of the true God left in old covenant?
And how does the Novus Ordo Missae being evil force us to take the position that "The Pope isn't the Pope, the cardinals aren't cardinals, none of the bishops or priests has any orders"? The very fact that these same men are the ones perpetrating the sacrilege is what makes it so heinous. If a simple layman were to offer the Novus Ordo, it would be bad, but not on the level of a priest of God taking part in it.
The validity of conciliar orders is another topic altogether. I do not have the authority to decide whether they're valid or not. The very fact that there is a question, however, precludes my approaching them for the sacraments. I will wait for the Church to decide the issue, and in the meantime will take the safer course.
Your point touching on how God will restore things after the chastisement has little bearing on the topic. That's His business, not mine. My job is to adore Him as He desires to be adored, not defend the indefensible.
The subjective culpability of each of the attendees at the Novus Ordo is an issue that we can't delve into because it's in the internal forum, but the nature of the act itself is certainly up for review. Their innocence or guilt doesn't change the fact that the act itself is sacrilegious.
I cannot speak for others, but my holding the this position has never lead to "a pharasaical scorn of Novus Ordo Catholics". On the contrary, having been one for 20 years I know all-too-well what it's like, and have nothing but compassion for them. I have little trouble making a distinction between their actions and their person, and the fact that they have an immortal soul which needs help.
The bottom line, Matthew, is that Bishop Williamson was wrong. He screwed up. Just accept the fact and move on.
