I grew up in the EF, having positions as altar server in the Low and High Mass (with apologies to malphono, I have never gotten the terms correct - perhaps because we used Low, High and Solemn High all the time and not the correct terms) and candle bearer, altar server, thurifer, and Master of Ceremonies at Solemn High Mass.
Last night I attended the Chrism Mass at our cathedral in Portland, along with several people from my parish who will be joining the Church this Saturday.
I turned to one of them after the Mass and said, casually, “What do you think of it?”; her response (she is in her mid 20’s) was “That was AWESOME!”. It was the OF, with a choir of 30 or 40 people who can sing better on their worst days than I on my best. The Archbishop has a splendid tenor voice and sung various parts of the Mass.
To anyone who says the OF cannot be as reverent as the EF, I say you are full of yourself, and not honest enought to admit your prejudices.
I do not object to anyone’s prejudices between their preference overall of the OF or the EF. I appreciate both. I also have the privilege of being in a parish that does not take liberties with the OF. Yes, the OF rubrics are not as complex as the EF’s. Yes, prayers were removed. But reverence is as reverence does; I have seen sloppy OF Masses and sloppy EF Masses, more of the former than the latter. But that has far, far more to do with the attitude of the priest than it does to the rubrics or the prayers.
But to answer the OP: one does not need any “arguments” at all, in any way, shape or form. Within the OF in my parish, there are those who prefer a quiet OF Mass; others prefer a vary sparse choir and hymns; others prefer a larger choir that sings with far more enthusiasm (and a bit more musical ability). And just so, some will prefer to attend an EF sung by a choir; others might prefer what we called a Low Mass, and it is entriely possible many will not want to attend regularly a Mass said in Latin.
But getting into anything that even remotely looks like “mine is better than yours” is going to turn a lot of people off, and very quickly. And failing to understand that the average person in the pew has little or no knowledge of rubrics and cannot be presumed to prefer one over the other is setting oneself up for failure. If the Mass is said in the EF at a time where the majority of people can get there without rearranging their schedule seriously (in other words, look for the OF with the largest attendance) that will give the greatest number of people a chance to attend one.
And don’t presume to simply make the OF go away at that time and replace it automatically with the EF, unless you want people to over-react negatively. People are creatures of habit, and habit runs deeper than conscious thought.
Have the Mass available once at the peak time. Then have it again, a month or 6 weeks later. It won’t take long, maybe three or 4 times, and the issue will sort itself out; if the second , 3rd or 4th time there is a significant drop off of attendance, then people will have voted with their feet. If attendance stays relatively the same, then one can expect to expand the number of times a month it will be offered.
All of this presumes that one has a priest available to say the EF, and whatever else is necessary, of that can be easily obtained on loan. None of it is rocket science.
And if attendance drops off or there is a very negative reaction, then move the EF to a different timeslot that is not as busy.
And the bottom rule should be: make no comparisons to the OF. People, while not liturgically trained in rubrics and prayers, can figure it out without you having to point it all out; they really are not stupid. Tell positively what the various rubrics and prayers do/show/state, where they came from (if you actually know), and then leave the rest alone.
Having been in seminary when Vatican 2 ended, and not a whole lot later asking my parents, relatives and others of their generation what they thought of the changes in the Mass, the vast majority indicated that the best thing they saw was the change to the vernacular. I have said it elsewhere, and I will repeat it: the vernacular has far, far more power than people want to give credit. Failing to learn that lesson will cause those who favor the EF untold frustration over trying to implement the EF. That does not mean that there are not more people wanting the EF (particularly after they have actually been to one or more) than meets the eye. But if anyone thinks that the EF, if introduced will take over to wild acclaim, they are not paying attention. Even the Pope in his letter accompanying SP indicated he did not think it would be widespread. It definitely has a place. It definitely should be made available. Those who love it should have it available, but their enthusiasm some times seems to fly in the face or reality.
