Liturgical Press Has An “Oops” Moment

“If we had known what the prayers really said, we would not have wanted to pray them any longer.” —Paul Inwood

This Sunday’s Communion Antiphon

This coming Sunday—10 August 2025—is the 19th Sunday in Ordinary Time (Year C). The COMMUNION ANTIPHON is really gorgeous, and two of its features are worth mentioning. First of all, the Gospel reading assigned is from Saint Luke, whereas the the antiphon—although it matches the account—comes from Saint Matthew. (If anyone can point to a similar example, please notify me.) Furthermore, if you look at the authentic Gregorian Chant version posted on the feasts website, you’ll notice that it’s MODE III but ends on the ‘wrong’ note. A comparable instance of such a ‘transposed’ chant would be KYRIE IV.

Using “Ye” Vs. “You” Correctly

Using “Ye” vs. “You” is rather tricky, because it depends upon which era one is trying to recreate—if that makes any sense. In other words, the rules haven’t always been the same for these two. Nevertheless, Father Philip George Caraman (the legendary Jesuit scholar) gives us a masterclass using Saint Luke’s Gospel. Father Caraman was close friends with Monsignor Ronald Knox, Evelyn Waugh, and Sir Alec Guinness.

“Pope Leo XIV Has Announced…”

My pastor asked me to write brief articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The most recent article speaks about the recent announcement by Pope Leo XIV, which does have an impact on church musicians. Scheduled for publication on 2025 08 10th, it’s called: “Pope Leo XIV Has Announced…”

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).
