Corpus Christi Watershed

Jesus said to them: “I have come into this world so that a sentence may fall upon it, that those who are blind should see, and those who see should become blind. If you were blind, you would not be guilty. It is because you protest, ‘We can see clearly,’ that you cannot be rid of your guilt.”

Is The Brébeuf Hymnal Too Scrupulous?

Why so much deliberation over every choice? Why so much discussion about a single stanza, or even a single word?

“Outer Space Hymn” (1966) • In A Catholic Hymnal

Discussion of horrible things that have (sadly) appeared in Catholic hymnals, such as: “And as we float along through outer space, | Past galaxies aglow in dark’s embrace, | Toward other worlds where brothers may await, | Do care for us now in our weightless state.” (Imprimatur 1966)+

    “Entrance Chant” • 4th Sunday of Easter
    You can download the ENTRANCE ANTIPHON in English for the 4th Sunday of Easter (11 May 2025). Corresponding to the vocalist score is this free organ accompaniment. The English adaptation matches the authentic version (Misericórdia Dómini), which is in a somber yet gorgeous mode. If you’re someone who enjoys rehearsal videos, this morning I tried to sing it while simultaneously accompanying my voice on the pipe organ.

    Music List • “Repertoire for Weddings”
    Not everyone thinks about sacred music 24/7 like we do. When couples are getting married, they often request “suggestions” or “guidance” or a “template” for their musical selections. I created music list with repertoire suggestions for Catholic weddings. Please feel free to download it if you believe it might give you some ideas or inspiration.
    —Jeff Ostrowski
    Beginning a Men’s Schola
    I mentioned that we recently began a men’s Schola Cantorum. Last Sunday, they sang the COMMUNION ANTIPHON for the 3rd Sunday of Easter, Year C. If you’re so inclined, feel free to listen to this live recording of them. I feel like we have a great start, and we’ll get better and better as time goes on. The musical score for that COMMUNION ANTIPHON can be downloaded (completely free of charge) from the feasts website.

Quick Thoughts

    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).

    When to Sit, Stand and Kneel like it’s 1962
    There are lots of different guides to postures for Mass, but I couldn’t find one which matched our local Latin Mass, so I made this one: sit-stand-kneel-crop
    —Veronica Brandt
    The Funeral Rites of the Graduale Romanum
    Lately I have been paging through the 1974 Graduale Romanum (see p. 678 ff.) and have been fascinated by the funeral rites found therein, especially the simply-beautiful Psalmody that is appointed for all the different occasions before and after the funeral Mass: at the vigil/wake, at the house of the deceased, processing to the church, at the church, processing to the cemetery, and at the cemetery. Would that this “stational Psalmody” of the Novus Ordo funeral rites saw wider usage! If you or anyone you know have ever used it, please do let me know.
    —Daniel Tucker

Random Quote

“However well equipped and trained a choir may be, all its good points may be obscured by an unsuitable accompaniment. In fact the organist can, in a large measure, either make or mar his choir. It must be owned, however, that the accompanist of Plainsong has to contend with many difficulties. […] The purist will still find his best enjoyment of the chant when it is sung unaccompanied, but to most a becoming accompaniment gives an added charm.”

— Benedictines of Stanbrook (1905)
