“A much greater source of anxiety to Us is the style of action of those who maintain that liturgical worship should shed its sacred character, who foolishly say we should substitute for sacred items & furnishings ordinary common things in daily use.” —Pope Saint Paul VI (14 Oct 1968)

Which Mass Goes With Which Season?

Jeff Ostrowski · December 30, 2015

897 Verdelot Polyphony “Deo Gratias” ANY BELIEVE the Ordinarium Missae to be more ancient than the Proprium Missae. Nothing could be further from the truth! Most of the Mass Ordinary is quite recent compared to the Proprium, especially the Creed (which to this day is placed in a different section). We have become accustomed to seeing “Mass in honor of Such-And-Such” and the entire setting will match; but this wasn’t how things were done 1,000 years ago. The KYRIE settings were in one place, the AGNUS DEI settings in another, and so forth.

Abbot Pothier and Dr. Peter Wagner made sure to remind those who used the Editio Vaticana that the Mass Settings—Mass I, Mass II, Mass III, and so forth—can be mixed with one another freely, but most people don’t realize this. For example, many believe that only the first Mass Setting can be used for Eastertide. (I once worked for a priest who thought that.) This view is indefensible yet popular. Perusing the ancient manuscripts, we see how freely the Mass settings were mixed, and this was true when the Renaissance composers were creating their masterpieces.

For instance, if you look at Missa de Beata Virgine—for the Blessed Virgin Mary—by Cristóbal de Morales, 1 you’ll see he uses Mass IX for the KYRIE. Mass IX in our current books has the suggestion “In festis B. Mariae Virginis,” and the Gloria was troped with Marian prayers before the Council of Trent. However, Morales uses Mass XVII for the SANCTUS, BENEDICTUS and AGNUS DEI. [The SANCTUS for Mass IX and XVII begin similarly, but there is no doubt Morales was using Sanctus XVII, not Sanctus IX, when you look at the rest of the piece.] Mass XVII is labeled as “Adventus et Quadragesimae.” 2 Francisco Guerrero (d. 1599) uses Mass IV for his “De Beata Virgine” KYRIE. Yet, in another Mass for the Blessed Virgin, Guerrero uses Mass IX for his KYRIE, just like Morales did!

Some Renaissance composers even set the “Deo Gratias” using polyphony. Verdelot’s Mass is an example, as you can see in the upper right corner.



NOTES FROM THIS ARTICLE:

1   Fr. Morales was a Spanish priest who died in 1553.

2   For the record, the plainsong melodies from Mass XVII are used by Morales in a very clear way that is quite striking. I don’t know if I’ve ever seen another Mass quite like it. It is almost a harmonization of the plainsong!

President’s Corner

    15th Sunday in Ordinary Time (Year C)
    This coming Sunday—13 July 2025—is the 15th Sunday in Ordinary Time (Year C). All the chants have been conveniently assembled and posted at the feasts website. The OFFERTORY, Ad Te Levávi, is particularly beautiful.

    Music Director Job • $80,000 per year
    Our readers will be interested in this job offering for Music Director at Saint Adalbert’s Basilica, located 40 minutes from where I live. My pastor was recently elevated to this basilica. He is offering $80,000 per year, plus benefits. I’m told Saint Adalbert’s Basilica is utterly gorgeous and contains one of America’s most magnificent pipe organs. It would be fantastic to have a colleague nearby!

    Simplest “Agnus Dei” Ever Published
    Our choir is on break during the month of July. I needed a relatively simple “Agnus Dei,” so I composed this setting for organ & voice in honor of Saint René Goupil. It has been called the simplest setting ever composed. I love CARMEN GREGORIANUM (“Gregorian Chant”), especially the ALLELUIAS, INTROITS, and COMMUNION ANTIPHONS. That being said, some have pointed out that certain sections of the Kyriale aren’t as strong as the Graduale or Vesperale. There’s a reason for this—but it would be too complicated to explain at this moment.

Quick Thoughts

    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.

    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.

    Antiphons Don’t Match?
    A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).
