Corpus Christi Watershed

Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”

    New Bulletin Article • “14 September 2025”
    My pastor requested that I write short 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 latest article (dated 14 September 2025) discusses OFFERTORY ANTIPHONS and contains a wonderful quote by Archbishop Fulton J. Sheen.
    —Jeff Ostrowski
    PDF Download • Draft Copy (Pamphlet)
    A few days ago, I posted a draft copy of this 12-page pamphlet with citations about the laity’s “full, conscious, and active participation.” Its basic point or message is that choir directors should never feel embarrassed to teach real choral music because Vatican II explicitly ordered them to do that! We’ve received tons of mail regarding that pamphlet, with many excellent suggestions for improvement. Please feel free to chime in!

    “Entrance Chant” • 23rd (Ordinary Time)
    This coming Sunday, 7 September 2025, is the 23rd Sunday in Ordinary Time (Year C). You can download the “Entrance Chant,” conveniently located at the feasts website. I also recorded a rehearsal video for it (freely available at the same website). The Communion Chant includes gorgeous verses in FAUXBOURDON. I attempted to create a rehearsal video for it, and it’s been posted at the feasts website, called by some: “church music’s best kept secret.”

Quick Thoughts

    Karl Keating • “Canonization Questions”
    We were sent an internet statement (screenshot) that’s garnered significant attention, in which KARL KEATING (founder of Catholic Answers) speaks about whether canonizations are infallible. Mr. Keating seems unaware that canonizations are—in the final analysis—a theological opinion. They are not infallible, as explained in this 2014 article by a priest (with a doctorate in theology) who worked for multiple popes. Mr. Keating says: “I’m unaware of such claims arising from any quarter until several recent popes disliked by these Traditionalists were canonized, including John XXIII, Paul VI, and John Paul II. Usually Paul VI receives the most opprobrium.” Mr. Keating is incorrect; e.g. Father John Vianney, several centuries ago, taught clearly that canonizations are not infallible. Archbishop Fulton J. Sheen would be another example, although clearly much more recent than Saint John Vianney.

    Vatican II Changed Wedding Propers?
    It’s often claimed that the wedding propers were changed after Vatican II. As a matter of fact, that is a false claim. The EDITIO VATICANA propers (Introit: Deus Israel) remained the same after Vatican II. However, a new set of propers (Introit: Ecce Deus) was provided for optional use. The same holds true for the feast of Pope Saint Gregory the Great on 3 September: the 1943 propers (Introit: Si díligis me) were provided for optional use, but the traditional PROPRIA MISSAE (Introit: Sacerdótes Dei) were retained; they weren’t gotten rid of. The Ordo Cantus Missae (1970) makes this crystal clear, as does the Missal itself. There was an effort made in the post-conciliar years to eliminate so-called “Neo-Gregorian” chants, but (contrary to popular belief) most were retained: cf. the feast of Christ the King, the feast of the Immaculate Conception, and so forth.

    Solemn “Salve Regina” (Chant)
    How many “S” words can you think of using alliteration? How about Schwann Solemn Salve Score? You can download the SOLEMN SALVE REGINA in Gregorian Chant. The notation follows the official rhythm (EDITIO VATICANA). Canon Jules Van Nuffel, choirmaster of the Cathedral of Saint Rumbold, composed this accompaniment for it (although some feel it isn’t his best work).

“The Chasuble, or upper garment, represents the purple garment which the soldiers put upon Jesus Christ, and the heavy cross that He carried on His blessed shoulders to Mount Calvary.”
