The last time I checked, out of 17,300+ parishes in the US, lest than three percent (3%) had an Extraordinary Form Mass of any sort. By any sort, I mean the range from an all EF parish, with Sunday and weedeay Masses in the EF form, to parishes which have one Ef Mass on Sunday (including some which have a Low EF early on Sunday), to parishes which have an EF Mass, once a week on Saturday morning, to parishes with an EF every toher weekm to parishes which have an EF Mass once every other month. And parishes which are all EF are in a small minority.
It has been said in this thread (and elsewhere) now much more reverent the EF is. However, it has also been siad, and bears repeating, that there are very few priests who say the Ef - and they want to; and very vew people who go to them (out of all Catholics attending Mass within the same time period) and they want to be at the EF.
I am 71; and I grew up with a pastor who could say the 6:30 a.m. Mass weekdays in 15 to 17 minutes. He also had a terrible problem with alcohol, which I will not get further into. But he most certainly was not alone in how he said Mass. He could also pull out the stops for a Solemn High Mass with all the pomp and circumstance one could wish for.
It is also true that only a minority of parishioners, when I was growing up, had purchased a missal with translations; and the vast majority of people were not fluent in Latin as it was not widely taught as a spoken language. the majority of people were “fulfilling their duty” and said the Rosary or read pamphlets of prayers other than the Mass. .
None of that is said to detract from the EF as it is said today, I attended Masses in the EF prior to the introduction of the OF which were reverent; and I attended those which were rushed and less than reverent. But to those who take the position that the EF is by its nature more reverent, I say poppycock, simply because I choose not to use gutter language. Both are the Mass; both have the Eucharist, and both can be said very reverently and both over history have been said irreverently. Reverence is not done by what the priest says, but how he says it.
