I received this by e-mail from a priest:
Long time reader, first time questioner.
I’ve been celebrating the TLM since Winter ’06.
In my parish, I celebrate the TLM on Tuesdays and Sundays for the faithful. My question is, can I celebrate more than one TLM on one day if needs be. The question has been raised about Sundays.
Summorum p5, art 2
Celebration in accordance with the Missal of Bl. John XXIII may take place on working days; while on Sundays and feast days one such celebration may also be held.
Celebratio secundum Missale B. Ioannis XXIII locum habere potest diebus ferialibus; dominicis autem et festis una etiam celebratio huiusmodi fieri potest.
‘una’ is confusing me slightly. It seems that it can be the definite ‘one’ or the indefinite in this context. Further, no article is given for ferials.
So far I have erred on the conservative side and stuck with one.
Sticking closely to the text, here is how I render it:
§ 2. Celebration according to the Missal of Bl. John XXIII can take place on weekdays; on Sundays and feasts, however, there can be also one celebration of this kind.
I think the Latin tells us that we can have one such Mass.
However, we must take into account that this document may show the influence of Italian: "una celebrazione" need not limit the number of Masses to only one. But, we do have to stick to the Latin.
At the same time, I am mindful of the comments of His Eminence the Cardinal President of the Pont. Comm. Ecclesia Dei. It seems to me that, remembering also the generosity the late Pontiff desired, we may think that some latitude is allowed here so long as those who desire to participate at celebrations of the Novus Ordo are accomodated. It strikes me that adding a Mass, even a second TLM, could be allowed so long as a Novus Ordo Mass is not cut from the scedule, being mindful of course of the reasonable restriction on how many Masses a priest can celebrate on a day, even for good pastoral reasons.
In the meantime, I think you are not making a mistake be keeping to one only. Give this a little time.
