I think you're missing Fr. Cekada's real point, Hobbledehoy. It's at the end of the last article of his that he linked to and I've highlighted it below:
That said, all the foregoing questions assume that the sole principle that must determine how traditional priests perform the liturgy is the liturgical legislation of “the last true pope.”
But this is not as simple as it sounds, because before a priest can maintain that the Pius XII legislation alone is legally binding, he must first demonstrate conclusively that John XXIII and Paul VI (at least before the end of 1964) were not true popes.
Until he does so, he must consider himself bound by all the John XXIII changes — “legally binding” is your principle, remember — as well as all the early Paul VI changes.
(Among the early Paul VI changes are the following: At Mass the priest never recites texts that the choir sings, bits of the Ordinary are sung or recited in English, the Secret is said aloud, the “Per Ipsum” at the end of the Canon is recited aloud, the “Libera Nos” is recited aloud, “Corpus Christi/Amen” is used for the people’s communion, the Last Gospel is suppressed, Scripture readings are proclaimed in the vernacular alone and facing the people, lay lectors/commentators assist the priest, the “Pater Noster” is recited in English, etc.)
In the case of both Roncalli and early Montini, a putative legislator was “in possession.” If observing the liturgical legislation of “the last true pope” is supposedly the golden norm for traditional Catholic worship, shouldn’t Father then follow the “safer course” by chopping up the Mass and training the lectors, just in case?
Since the “last true pope” principle leads to other problems, what then?
The answer is simple: Follow the liturgical rites that existed before the modernists started their tinkering.
We traditionalists endlessly reaffirm our determination to preserve the traditional Latin Mass and the Church’s liturgical tradition. To my way of thinking, it makes no sense whatsoever to preserve the liturgical “tradition” of Holy Week ceremonies invented in 1955, transitional Breviary rubrics, and “reforms” that lasted for all of five years.
The Catholic liturgy we seek to restore should be the one redolent of the fragrance of antiquity — not the one reeking with the scent of Bugnini.
So the principle Father argued for is not which pope's
law applies (Leo XIII, Pius X, Pius XII, etc.), but that
traditional priests should follow rites that are not tainted with modernist influence. And really, what's so wrong with that — instead of engaging in legalistic quibbling and winding up with Bugnini?
And I don't think you should be offended by him saying that a priest usually knows a lot more about the liturgy than an average layman. It's just a statement of reality, like saying a farmer probably knows more about farming than a taxi driver does. :farmer:
