On November 16, 1955, Pope Pius XII issued Maxima Redemptionis Nostrae Mysteria on the reform of Holy Week and the Triduum. Those attending the Holy Triduum according to the Pian reforms of 1955 experience an abridged liturgy. Having undertaken the music and liturgical planning for both, there is no doubt, at least in my opinion, that the structural reforms were unnecessary and represent a significant loss and disconnect. What was necessary, in my view, was a restoration of the hours so that the liturgical action coincided with that of the LORD's suffering and ancient practice and shedding the ridiculous practice of Holy Thursday in the morning and the Vigil eliminated on Holy Saturday to a morning service for the very reasons the Pope described in the above linked document. Further, the structure of society was changing, and the faithful could no longer attend these sacred services. They became the realm of clericalists.
The current Pope, Francis, granted permission for the pre-55 Holy Week to be used on an experimental basis for three years by the FSSP. The ICRSS has, for many years, conducted the services according to the older books. This experimental permission was not granted to diocesan priests. However, both of these used the prior liturgical books, but with the new hours as evidenced here:
If the FSSP and ICRSS can adapt the pre-55 liturgy to the new hours, how is it possible for others to outright refuse to follow the liturgical rubrics? How is this any different from some modernist deciding for himself in the new rite? The fact is, there is no difference!
The very idea that in 2025 a Holy Thursday Mass and procession is held after noon at 3 o'clock or Good Friday at 8 o'clock at night is a direct contradiction of Pope Pius XII and every pope that has come after. It is an insult to the liturgy and to the people who cannot attend these hours. It is completely in defiance of Pope Pius XII and the rubrical law for either the Missal of Pius XII, John XXIII or Paul VI. Interpreting liturgical rubrics of prostration meant for clerics to the people forcing people who may not be able to get down or get up to prostrate to kiss and venerate the cross, is an abomination to human dignity, weight, age, even back-braces don't matter. The blatant passing on the requirement to "name" the present Pope in the public prayers is completely and utterly reprehensible within the Roman Catholic liturgy, no matter what one may think of the actions of any current Pontiff and reveals a serious deficiency in thinking.
Sadly, clericalism and fetishism have both invaded the traditional movement.
