Serious discussion of the Roman liturgical reforms in traditionalist circles, at least until respectable scholars like Laurence Hemming questioned the 1911 breviary reforms, usually contrasted "pre-1955" with 1962 and highlighted glaring differences such as what Pius XII did to Holy Week as a test run for the reformed liturgy. Something less noticeable is what differs on a more regular basis.
Today, until 1955, would have been the feast of St. John the Evangelist, Our Lord's favorite Apostle. One correspondent, who has successfully implemented proper Last Gospels, public horae minores, and some pre-reform Holy Week days at his parish, lamented that his pastor would be observing Sunday within the octave of the Nativity rather than St. John. Offhandedly, I asked how many Apostles had the 1962 liturgy entirely disregarded in the last year; unexpectedly, he told me five. In another conversation a while back I was speaking with an ordo compiler who offhandedly remarked "Nothing for St Andrew this year. He was only the first Apostle."
I am unsure how strictly the Roman liturgy ranked the Apostles before St Pius V's revisions in 1568-1570. Most local European rites give the Apostles, even Peter & Paul, a semi-double rank. Pius V upgraded many feasts to double rank, which allowed them to outrank Sunday. This does not, however, put the pre-Pius V system on par with 1962. Although a semi-double did not outrank Sunday, it was not discarded. Semi-double feasts impeded by Sunday were transferred to the next ferial day. Under St Pius X's system Apostles' Double of the Second Class feasts continued to outrank Sundays, even though lesser feasts could not (they did, however, warrant commemorations at Mass and in the Office). Even under Pius XII's 1955 revisions there were provisions for commemorating the now lessened feasts of the Apostles. The simplification of commemorations in 1962 breaks with all tradition in completely and utterly doing nothing for Apostles not named Peter & Paul when their feasts fall on Sunday.
Wholesale liturgical restoration is not feasible at this point, even within traditionalist communities, which are quite happy just to get their Mass once a week and have a place at the local parish. We cannot begrudge Catholics gratitude for this. We can, however, push for some provision to be made for such boisterous flaws in a liturgy that purports to be the "Mass of all times." Would it be too much for Fr. Tradman to do a commemoration and proper ultimum evangelium for St. John tomorrow? He only wrote a Gospel.
