Changes of the Missal 1920
There are many, many changes in the rubrics (both at the beginning and throughout) made for clarity. An “Additiones and Variationes” according to the norms of St. Pius X is added. But some of the main ones
The celebrant is instructed to bow profoundly to the altar, not incline his head when leaving was previously customary.
Many of the preparatory prayers of the priest have indulgences attached.
There is no change in the Ordinary unless you want to count the fact that only four intonations of the ’ Gloria ’ are retained and one intonation of the ’ Credo.’
The new Prefaces of St. Joseph and and for the Dead’ are inserted in their proper place, and the Prefaces of the Nativity and of the Ascension are also given in the ferial tone. Plus later there was the addition of the prefaces for the Sacred Heart and the Kingship.
In the Proper of Seasons, wherever the Holy Innocents is the patron, the ’ Gloria,’ ’ Alleluia,’ and ’ Ite Missa est ’ are said. Also a reduction in the commeorations that goes with the change for the octaves that I mentioned earlier.
The Secret of the Prayer of the BVM to be said on lower ranked feasts “Deus qui salutis” was changed from “Muneribus nostris” to another -“Tua Domine propitiation”
In the Secret of the Mass of Thursday after the first Sunday of Lent, the word propensius is substituted for propitius.
On Good Friday, the Improperia are divided for the deacon, subdeacon and celebrant.
In the Post Communion of Holy Saturday, Easter Sunday, and Easter Monday, the conclusion is “in unitate ejusdem Spiritus Sancti.”
Proper of Saints: I’ve not yet finished going through all- only the major feasts and the Popes. It’s a bit tiring
But there are quite a few changes wherby the Commons have been switched- more than those listed below. I was also happily aided by an article on the changes to the Gospels.
January 19, St. Canute. The Gospel is no longer Si quis vult from the Mass Sacerdotes Dei, but Nolite arbitrari from the Mass In virtute. Likewise the Secret and ostcommunion are no longer from the Mass In Virtute but from the Mass Laetabitur.
January 31,St. Peter Nolasco. The Secret and Postcommunion are no longer from the Mass Justus, but from the Mass Os Justi.
February 14, St. Valentine. Secret “Oblatis” is changed to another one “Suscipe”
February 15, Ss. Faustinus and Jovita. For the Secret “Oblatis” and Postcommunion “Haec Nos” are substituted the Secret and Postcommunion of the Mass Intret. (many martyrs)
March 6, Ss. Perpetua and Felicitas. The Postcommunion Praesta is changed to a new one, “Mysticis, Domine”.
March 10, 40 Martyrs. The Secret “Sacrificiis” is replaced by “Preces, Domine,” and in place of the Postcommunion “Quaesumus” is “Sanctorum tuorum”.
April 23,St. George. Outside Eastertide, the Gospel Nolite arbitrari from the Mass In Virtute takes the place of the Gospel Siquis lenit from the Mass Statuit.
April 29, St. Peter Martyr. The Gospel, “Nihil est opertum” from the Mass Laetabitur, takes the place of the Gospel “Si quis vult” outside Eastertide
May 7, St. Stanislaus. Outside Eastertide, the Gospel is “Si quis vult” from the Mass Sacerdotes Dei, instead of “Si quis venit” from the Mass Statuit.
May 18 St. Venantius. Outside Eastertide the Gospel is no longer “Si quis venit” from the Mass Statuit, but “Nolite arbitrary” from the Mass In virtute.
May 26. St. Eleutherius. The Secret is “Munera” instead of “Hostias” and the Postcommunion “Haec nos” instead of “Refecti”. What essentially was done was the switching of the Common as it stood then from Statuit Ei to Sacerdotes Dei. This was common for several other Popes sin the calendar.
May 30, St. Felix. same.
August 16, St. Joachim. The word “ferto” from “confer” in Gradual Versicle: Joachim, sanctae conjux Annae, pater almae Virginis, hic famulis ferto salutis opem.
September 22, St. Thomas. The Secret is “Sancti Thomae”, and the Postcommunion “Deus fidelium remunerator”, both from the Mass Sacerdotes Dei.
September 28, St. Wenceslaus. The Gospel “Nolite arbitrary” is substituted for “Si quis vult”
October 7, Holy Rosary. In the Preface the words Et te in Festivitate are substituted for Et te in sollemnitate.
November 10, Martyrs Trypho, etc. The Epistle begins, “Fratres : Existimo, quod non sunt condignae”
November 11, St. Martin. A new Secret “Sanctifica, quaesumus” instead of “Da, misericors Deus”
