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.”

“Ad Orientem” and Granovetter’s Threshold Models of Collective Behavior

Richard J. Clark · August 5, 2016

RJC_Francis_Ad-Orientem Pope Francis celebrates “ad orientem” • altar of St. John Paul II • 31 October 2013 ’M A BIT LATE to the party. Copious ink has already been spilled regarding Cardinal Sarah’s address at the Sacra Liturgia conference in London and his comments regarding celebrating Mass ad orientem in the Novus Ordo (“New order of the Mass”). Robert Cardinal Sarah was appointed by Pope Francis as Prefect for the Vatican’s CONGREGATION FOR DIVINE WORSHIP in 2014.

I’ve watched as many have been freaking out over Cardinal Sarah’s encouragement to follow rubrics that have been in place for over fifty years since Vatican II. The anxiety was so palpable that United States Conference of Catholic Bishops Committee on Divine Worship felt compelled to diffuse the brewing controversy in a letter clarifying that “no changes to the General Instruction of the Roman Missal are expected at this time, nor is there a new mandate for the celebrant to face away from the assembly.”

No new instructions. No new mandate. That’s exactly right and exactly the point.

The overreaction to Cardinal Sarah’s address is quite understandable because precious few Catholics know what ad orientem in the Novus Ordo is and what it is not. Lack of knowledge is not the people’s fault. In fact, they deserve to know the truth. It is time for catechesis to begin and for ignorance to end so that the faithful may develop their own informed opinions.

Andrew Leung has helpfully pointed out a few common misunderstandings. The most important misconception is that the priest faces the altar throughout the entire Mass. This is not even close to the truth. Leung sets the record straight in his article, Three False Ideas about “Ad Orientem” Celebration. The reality is a hybrid: the priest faces the people for most of the Mass, but faces the altar during the Liturgy of the Eucharist (with specific exceptions):

In the Novus Ordo, the priest begins the Introductory Rite at the presider’s chair, which faces the people in most cases. The Liturgy of the Word takes place at the ambo facing the people. The part celebrated ad orientem is the Liturgy of the Eucharist…After the Liturgy of the Eucharist, the priest returns to the presider’s chair for the Concluding Rite.

The following cannot be emphasized enough: When addressing the people (e.g., in the dialogues), the priest turns to face the people. When offering sacrifice to God, the priest faces the altar. Leung outlines the important distinctions, indicated in the rubrics here.

The priest is instructed by the rubrics to turn towards the people when he addresses them in the Liturgy of the Eucharist (at Oratre fratres; Pax Domini sit semper; and Ecce Agnus Dei).

ETTING BACK TO THE “freaking out”—understand this: the Novus Ordo finds both acceptable and always has. It is not an “either/or” but “both/and.” While the Roman Missal assumes Masses are celebrated ad orientem (hence the rubrics specify “facing the people” at specific times) the General Instruction of the Roman Missal (controversy over translation aside) states the following: “The altar should be built separate from the wall, in such a way that it is possible to walk around it easily and that Mass can be celebrated at it facing the people, which is desirable wherever possible.” (GIRM §299)

I am not advocating one way over the other at this time because our greatest priority is to celebrate the Mass with dignity and reverence. Facing East or West is secondary for now. But some find ad orientem a useful tool to this end. Regardless, we have much to learn from each practice and from the collective wisdom of the ages.

HILE “AD ORIENTEM” carries with it a good deal of emotional baggage for some, young Roman Catholics bring fresh perspectives not held by their parents and grandparents. With each passing year, the tide is turning. But adopting a different practice—even if from time to time—will be slow.

So what will this take?

THIS IS WHERE SOCIOLOGIST, Mark Granovetter comes in. His landmark 1978 publication Threshold Models of Collective Behavior (American Journal of Sociology 83 [May]: 489-515) is anything but dull. It has been applied to explaining everything from riots, the NFL draft, and miscues by politicos. (His theory is much discussed in this fascinating episode of WBEZ’s popular This American Life.)

Its main premise “is that of ‘threshold’: the number or proportion of others who must make one decision before a given actor does so.” Simply put, human nature dictates that many people are unwilling to act a certain way—even if one knows it’s a better choice—unless they see others doing it first. Many won’t “jump in” unless a large number of people are already engaging in a particular activity.

Key to this understanding, Granovetter explains that the “threshold” is different for different people. E.g., Many Millennials may have a lower threshold for adopting new digital technology while those of retirement age may have a higher threshold.

The threshold of a congregation is in play too, possibly causing the threshold of any pastor to be that much higher. What is required is a pastor with a “low threshold” who is willing to do the hard work of catechesis and willing to finesse the inevitable complaints that follow.

HE “SPIRIT OF VATICAN II” sometimes contradicts Vatican II. For decades, we were told that the priest celebrated Mass (for over a millennium) with his “back to the people.” Quite interestingly, in the early 1990s, one of my choir members opened my eyes to a new way of thinking. It was new to me then and will be new to many today. He said, “You know, the old Latin Mass made sense in this regard: the people and the priest faced the same way. They faced God together.”

I propose the idea that the Novus Ordo, a hybrid of both facing the people and facing God, got it right—a “both/and” scenario consistent with both Vatican II and the “Spirit of Vatican II.”

I propose the notion that priest and people facing God together is an act of unity. “…they are to form one body, whether in hearing the Word of God, or in taking part in the prayers and in the singing, or above all by the common offering of the Sacrifice and by participating together at the Lord’s table. This unity is beautifully apparent from the gestures and bodily postures observed together by the faithful.” (GIRM No. 96)

I propose the possibility that doing so deemphasizes the centrality of the priest (a humble servant acting In persona Christi), places him in union with the faithful, and ultimately emphasizes the centrality of Christ.

I acknowledge the reality that most of the faithful are not ready to embrace ad orientem on a regular basis, if at all. Perhaps in time, those with a “lower threshold” will model this and more may someday follow.

I hope someday, ad orientem will be less frightening when people actually know what it is, why it is, and what it is not. My hope is that it will be normative—“no big deal!”

But most assuredly, Jesus loves you no matter which way the priest faces. Don’t freak out!

    Music List • (3rd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 3rd Sunday of Lent (8 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its stern INTROIT (“Óculi mei semper ad Dóminum”) is breathtaking, and the COMMUNION (“Qui bíberit aquam”) with its fauxbourdon verses is wonderful. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    “Samaritánæ” (3rd Sunday of Lent)
    With regard to the COMMUNION for the 3rd Sunday of Lent (Year A), the Ordo Cantus Missae—which was published in 1969 by the Vatican, bearing Hannibal Bugnini’s signature and approbation in its PREFACE—inexplicably introduced a variant melody and slightly different words, as you can see by this comparison chart. When it comes to such items, they’re always done in secrecy by unnamed people. (Although it is known that Dom Eugène Cardine collaborated in the creation of the GRADUALE SIMPLEX, a book considered by some to be a travesty.)

    PDF Download • “Ubi Caritas” (SATB)
    I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.

Quick Thoughts

    “Dies Irae” • A Monstrous Translation
    It isn’t easy to determine what Alice King MacGilton hoped to accomplish with her very popular book—A Study of Latin Hymns (1918)—which continued to be reprinted in new editions for at least 34 years. This PDF file shows her attempt to translate the DIES IRAE “in the fewest words possible.” There’s a place for dynamic equivalency, but this is repugnant. In particular, look what she does to “Quærens me sedísti lassus.”
    —Jeff Ostrowski
    PDF Download • “Holy, Holy, Holy”
    For vigil Masses on Saturday (a.k.a. “anticipated” Masses) we use this simpler setting of the “Holy, Holy, Holy” by Monsignor Jules Vyverman (d. 1989), a Belgian priest, organist, composer, and music educator who ultimately succeeded another ‘Jules’ (CANON JULES VAN NUFFEL) as director of the Lemmensinstituut in Belgium. Although I could be wrong, my understanding is that the LEMMENSINSTITUUT eventually merged with “Catholic University of Leuven” (originally founded in 1425). That’s the university Fulton J. Sheen attended.
    —Jeff Ostrowski
    Grotesque Pairing • “Passion Chorale”
    One of our rarest releases was undoubtably this PDF scan of the complete Pope Pius XII Hymnal (1959) by Father Joseph Roff, a student of Healey Willan. One of the scarcest titles in existence, this book was provided to us by Mr. Peter Meggison. Back in 2018, we scanned each page and uploaded it to our website, making it freely available to everyone. Readers are probably sick of hearing me say this, but just because we upload something that doesn’t necessarily mean it’s wonderful or worthy of imitation. We upload many publications precisely because they are ‘grotesque’, interesting, or revealing. Whereas the Brébeuf Catholic Hymnal had an editorial board that was careful and sensitive vis-à-vis pairing texts with tunes, the Pope Pius XII Hymnal (1959) seems to have been rather reckless in this regard. Please take a look at what they did with the PASSION CHORALE and see whether you agree.

Random Quote

“In older times we referred to humans as the human race, but according to this foundation we are being classed with the animals on the farm, the cow, the horse, the mule […] According to this foundation, I have no right to be born, for I am the youngest of 16 children, and God bless my mother for every one of them!”
