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.”

    Spectacular Communion Setting!
    The FAUXBOURDON setting of the Communion for the Baptism of the Lord (which will occur this coming Sunday) strikes me as quite spectacular. The verses—composed by the fifth century Christian poet, Coelius Sedulius—come from a long alphabetical acrostic and are deservedly famous. The feast of the LORD’S BAPTISM was traditionally the octave day of Epiphany, but in the 1962 kalendar it was made ‘more explicit’ or emphasized. The 1970 MISSALE ROMANUM elevated this feast even further.

    PDF • “Music List” (Sunday, 11 January)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Feast of the Baptism of the Lord (SUNDAY, 11 January 2025). If such a thing interests you, feel free to download it as a PDF file. The FAUXBOURDON verses for the Communion Antiphon—to say nothing of the antiphon itself—are breathtaking. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the monumental feasts website alongside the official texts in Latin.
    —Jeff Ostrowski
    Epiphany Hymn • “New 2-Voice Arrangement”
    The Von Trapp Family Singers loved a melody that was featured heavily (perhaps even “too heavily”) in the Brébeuf Hymnal. It goes by many names, including ALTONA, VOM HIMMEL HOCH, and ERFURT. If you only have one man and one woman singing, you will want to download this arrangement for two voices. It really is a marvelous tune—and it’s especially fitting during the season of Christmas and Epiphany.

Quick Thoughts

    “Reminder” — Month of January (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.
    —Jeff Ostrowski
    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.
    —Jeff Ostrowski

Random Quote

The Princess of the Palatinate once described German Protestantism to Louis XIV with this formula: “In our country, everyone makes up his own little religion.” Every priest, or almost every priest, is at this point today. All the faithful have to say is “Amen.” They are still blessed when the pastor’s religion does not change every Sunday, at the whim of his reading, the foolery he has seen others at, or at his own pure fancy.

— Professor Louis Bouyer (1968)
