I found a website that quotes Fr. Kramer on the above subject of Pope Pius Xll and the "new rites."

"
Fr. Kramer: "When Pius Xll spoke of popes having the authority to introduce "new rites," he was using the term in a highly restrictive sense, according to a well established usage; in precisely the same manner that Pius V refers to the Mass liturgy in Quo Primamus, a "new rite" -- a newly restored addition of the traditional rite "handed down by the Roman Church."
The 1570 "new Rite" of Quo Primumus is practically identical to the rite in the printed Missale Romanum of 1474. Quite obviously the error was not made by Pius X, who understood perfectly the nuances of usage of ecclesiastical terms as they are traditionally employed; but having a highly specialized knowledge of the subject matter, he intended the term to be understood in precisely the same manner that it had been traditionally meant."
Sorry Meg, but that's just more crazy nonsense from Fr. Kramer. His position is positively Orwellian.
I would be hard pressed to believe that he's even read the docuмent Mediator Dei from start to finish or even a third of it.
Pius XII was incredibly clear and he did not hold Fr. Kramer's fringe position.
49. From time immemorial the ecclesiastical hierarchy has exercised this right in matters liturgical. It has organized and regulated divine worship, enriching it constantly with new splendor and beauty, to the glory of God and the spiritual profit of Christians. What is more, it has not been slow - keeping the substance of the Mass and sacraments carefully intact - to modify what it deemed not altogether fitting, and to add what appeared more likely to increase the honor paid to Jesus Christ and the august Trinity, and to instruct and stimulate the Christian people to greater advantage. 52. Thus, for example, as Catholic doctrine on the Incarnate Word of God, the eucharistic sacrament and sacrifice, and Mary the Virgin Mother of God came to be determined with greater certitude and clarity, new ritual forms were introduced through which the acts of the liturgy proceeded to reproduce this brighter light issuing from the decrees of the teaching authority of the Church, and to reflect it, in a sense so that it might reach the minds and hearts of Christ's people more readily.Fr. Kramer's tortured position is the idea that "introducing a new rite" doesn't mean introducing a new rite, it means modifying an old rite.
But Pius XII doesn't conflate the two:
58. It follows from this that the Sovereign Pontiff alone enjoys the right to recognize and establish any practice touching the worship of God, to introduce and approve new rites, as also to modify those he judges to require modification
You see the language there? Recognize, establish ANY practice touching the worship of God. He can INTRODUCE and APPROVE NEW RITES.
In addition to that he can also modify any rite, new or old if he so chooses.
He also points out that the Pope can introduce the vernacular into the liturgy.
60. The use of the Latin language, customary in a considerable portion of the Church, is a manifest and beautiful sign of unity, as well as an effective antidote for any corruption of doctrinal truth. In spite of this, the use of the mother tongue in connection with several of the rites may be of much advantage to the people. But the Apostolic See alone is empowered to grant this permission. It is forbidden, therefore, to take any action whatever of this nature without having requested and obtained such consent, since the sacred liturgy, as We have said, is entirely subject to the discretion and approval of the Holy See.[/b]And appealing to Quo Primum is ridiculous. Since Quo Primum allows for other "new rites" that could have been established as late as 1370.
That means that the "traditional rites" that the Pope is bound by the Council of Constance could have been only 48 years old at the time of Constance for Pope SAINT Pius V to have considered them exempt from abrogation by Quo Primum.
So Constance claims the Popes are bound to the "traditional rites" but a liturgy younger than Fr. Kramer is now, at the time of Constance would be exempt from Pro Quimum.
