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.”

Is It An Obligation?

Fr. David Friel · December 8, 2013

HE DATE OF THE IMMACULATE CONCEPTION this year is thoroughly confusing, even to Mass-going cradle Catholics. The transfer or omission of holydays that fall on Friday, Saturday, Sunday, or Monday is a mystery to most, and I am afraid I won’t be able to shed much explanatory light.

What I would like to do, however, is give an encouragement.

This year (in the Ordinary Form), the Solemnity of the Immaculate Conception is superceded by the Solemnity of the Second Sunday of Advent. As such, the holy day will be observed on Monday, December 9th. (In the Extraordinary Form, the Immaculate Conception remains a first class feast and is not supplanted by the Mass of Sunday; the orations for the Sunday, however, are commemorated.)

While Monday therefore will not be a holy day of obligation, it will still be a holyday. So my encouragement is this: although attendance at Mass is not obligatory, let’s make sure to celebrate Monday as the holyday that it is.

Tomorrow, if you are able to go to Mass, go. It doesn’t matter that it’s not required. If you are able to avoid work, do so. If you have an opportunity to make a visit to the Blessed Sacrament, take it. If you want to mark the day with your family, pray the rosary together or sing a hymn to the Blessed Mother after dinner.

These suggestions hold true also for holydays that are, in fact, holy days of obligation. It is quite possible to go to Mass on those days, but not really observe the “spirit” of the holyday.

On the patronal feast of our country, let’s not miss the opportunity to honor the Blessed Lady and renew our devotion to her. O Mary, conceived without sin: pray for us who have recourse to thee!

    “Holy Name Hymn” (2-Voice Arrangement)
    When we post a direct URL link, we frequently get thousands of downloads. But when scrolling is required, very few take the time. I mention this because those who click on this URL link and scroll to the bottom can download—completely free of charge—a clever 2-voice arrangement for a famous hymn to the Most Holy Name of Jesus. In a pinch, it can be nicely sung by one male and one female! It will be of interest to those who seek arrangements for two voices.

    PDF Download • Introit (3rd Sn. Ord.)
    This coming Sunday, 25 January 2026, is the 3rd Sunday in Ordinary Time (Year A). The ENTRANCE CHANT (“Dóminus secus mare”) is somewhat rare because it comes from the New Testament. The authentic version in Latin—of astounding antiquity—was jettisoned in 1955 but restored in 1970. This rehearsal video has me attempting to sing the melody while simultaneously accompanying myself on the organ. I encourage you to print off the organ accompaniment (PDF) and play through it because it has extremely ‘happy’ harmonies.

    “Lamb of God” (Musical Setting)
    The MASS OF SAINT ANNE LINE has been quite popular ever since ROMAN MISSAL Third Edition was released circa 2011. You can now download the musical score (PDF) for this setting, placed into five (5) different keys; i.e. “pitch levels” that are high and low. This makes it possible to adjust based upon who’s singing at which time of day.

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.

    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.

Random Quote

“At the hour for the Divine Office, | as soon as the signal is heard, | let them abandon whatever they may have in hand | and hasten with the greatest speed, | yet with seriousness, so that there is no excuse for levity. | Let nothing be preferred to the sacred liturgy.”

— Rule of St. Benedict (Chapter 43)
