For those of you who may have been watching EWTN last night you may have noticed a mistake that seems to becoming more common.
Before I say any more, I have to clarify something. I want to say that I am highly devoted to EWTN and that I think the mistake made last night was an honest one.
The mistake made was regarding the use of the Extraordinary form of the Roman Rite on the Easter Triduum. Raymond Arroyo mentioned that Summorum Pontificum said that the Extraordinary form could not be used on the Easter Triduum. This is not correct. This is a result of misreading Article 2 of Summorum Pontificum.
Here is the article in question (emphasis mine):
Art. 2. In Masses celebrated without the people [in other words, private masses], any priest of Latin rite, whether secular or religious, can use the Roman Missal published by Pope Blessed John XXIII in 1962 or the Roman Missal promulgated by the Supreme Pontiff Paul VI in 1970, on any day except in the Sacred Triduum. For celebration in accordance with one or the other Missal, a priest does not require any permission, neither from the Apostolic See nor his own Ordinary.
If you'll notice, the article only refers to private masses or "Masses celebrated without the people." It says that these Masses, the private ones, can't be celebrated during the Triduum under either form. It's written a bit awkward, but that is what it's stating. If it were stating that public Mass (as is the assumption) can't be celebrated during the Triduum it would also include the Missal of Paul VI, hence the conjunction "or." If that's so, then what missal can we use? Under that context, article 2 does not make sense.
Article 2 is just another article restating an established norm. Private Masses, including those done according to the Missal of Paul VI, have always been prohibited during the Easter Triduum. Before 1970 this was the case as well, as private Masses have ALWAYS been prohibited during the Triduum.
So, in short, either Missal may be used for public Masses during the Easter Triduum.
