“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)

President’s Corner

    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.
    —Jeff Ostrowski
    14th Sunday in Ordinary Time (Year C)
    Our choir is on break during the month of July. However, on the feasts website, the chants have been posted for the 14th Sunday in Ordinary Time (Year C), which is this coming Sunday: 6 July 2025.
    —Jeff Ostrowski
    Bugnini’s Statement (6 November 1966)
    With each passing day, more is revealed about how the enemies of the liturgy accomplished their goals. For instance, Hannibal Bugnini deeply resented the way Vatican II said Gregorian Chant “must be given first place in liturgical services.” On 6 November 1966, his cadre wrote a letter attempting to justify the elimination of Gregorian Chant with this brazen statement: “What really gives a Mass its tone is not so much the songs as it is the prayers and readings.” Bugnini’s cadre then attacked the very heart of Gregorian Chant (viz. the Proprium Missae), bemoaning how the Proprium Missae “is completely new each Sunday and feast day.” There is much more to be said about this topic. Stay tuned.

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.
    —Corpus Christi Watershed
    “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).

Random Quote

The Council of Trent taught: “In this divine sacrifice which takes place at Mass, the same Christ is present and is immolated in an unbloody manner, Who once on the Cross offered Himself in a bloody manner. For the victim is one and the same, now offering through the ministry of priests, Who then offered Himself on the Cross; only the manner of offering is different” (Session XXII, cap. 2, Denzinger, n. 940).

— Pope Pius XII (2 November 1954)
