Some rubrics were modified during the legitimate liturgical movement of the first half of the 20th century. They were not so much a change in the liturgy but a change in the approach to the liturgy. For example in 1923, the first permission was given by Pope Pius XI for the "Dialogue Mass." Later, the desires of St. Pius X in Tra le sollecitudini and Pope Pius XI with the early Dialogue permissions and again recommended by Bl. Pius X in Mediator Dei and De musica sacra et sacra liturgia and again by Blessed John XXIII in Rubricarum instructum (English here) were implemented. Truly, those that came after 1958 are less well known. There was no internet after all and parishes and people did not rush out to buy new Missals or even consider reading the version then of the GIRM.
Some questions that have been asked of us and arise are the simple terms of the Mass in the old rite and connected with these there are some important rubrics. Let us look at a simple guideline based on all of the documents above as to the names and their general rubrics relating to music and the spoken word:
|A new priest's first Solemn Mass with an "Assistant Priest" present.|
|Read Mass with one Server|
|Solemn Requiem held during Lent|
