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.”

“Ad Orientem” Explained

adorientem

HIS YEAR, the priest at my parish will be offering the Holy Sacrifice of the Mass ad orientem on Fridays during Lent. In parishes that are not used to having Mass offered ad orientem, introducing it at daily Mass on the Fridays of Lent is an excellent way to begin the practice. I wrote the following “explainer” to help my parishioners understand what’s going on and why.

What does “ad orientem” mean?

“Ad orientem” is Latin for “toward the East.” It refers to the direction that the priest faces during particular moments in the Holy Sacrifice of the Mass. Historically, Catholic churches and cemeteries have always been built along an East-West axis whenever possible. This is because the Holy Sacrifice of the Mass is not merely a closed-circle, communal event taking place between the priest and people, but a heavenly mystery encompassing the whole cosmos: “In the earthly liturgy we take part in a foretaste of that heavenly liturgy which is celebrated in the holy city of Jerusalem toward which we journey as pilgrims, where Christ is sitting at the right hand of God…” (Sacrosanctum Concilium, paragraph 8). 

It seems like the priest is facing the wrong way. What’s going on?

During those portions of the Mass that are addressed to the people, the priest faces the people. However, because the Eucharistic prayer is addressed to God the Father, the normal posture of the priest has always been to face with the people toward the Lord while the priest, acting “in persona Christi capitis” (“in the Person of Christ the Head”), re-presents Christ’s saving sacrifice to the Father in an unbloody manner through the power of the Holy Spirit.

Didn’t Vatican II get rid of this?

Actually, no. Nowhere in the documents of Vatican II (nor in any other magisterial documents before or since) has the Church ever directed the priest to face “versus populum” (Latin, “toward the people”) for the entire duration of the sacred liturgy. In fact, the current edition of the General Instruction of the Roman Missal (the priest’s “instruction book” for Mass) presumes the “ad orientem” posture because it directs the priest to turn and face the people at certain points, implying that he had not been facing them beforehand.

What does this mean for me?

While the priest’s “ad orientem” posture may seem unusual at first, with repeated exposure many people find that the “ad orientem” celebration allows them to enter more deeply into the prayer of the Mass and to focus more intently on the mystery of Christ’s Real Presence – Body, Blood, Soul, and Divinity – in the Most Holy Eucharist.

    Why A “Fugue” Here?
    I believe I know why this plainsong harmonizer created a tiny fugue as the INTRODUCTION to his accompaniment. Take a look (PDF) and tell me your thoughts about what he did on the feast of the Flight of Our Lord Jesus Christ into Egypt (17 February). And now I must go because “tempus fugit” as they say!

    New Bulletin Article • “12 October 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 12 October 2025) talks about an ‘irony’ or ‘paradox’ regarding the 1960s switch to a wider use (amplior locus) of vernacular in the liturgy.

    “Reminder” — Month of October (2025)
    Those who don’t sign up for our free EMAIL NEWSLETTER miss important notifications. Last week, for example, I sent a message about this job opening for a music director paying $65,000 per year plus benefits (plus weddings & funerals). Notice the job description says: “our vision for sacred music is to move from singing at Mass to truly singing the Mass wherein … especially the propers, ordinaries, and dialogues are given their proper place.” Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

Quick Thoughts

    “American Catholic Hymnal” (1991)
    The American Catholic Hymnal, with IMPRIMATUR granted (25 April 1991) by the Archdiocese of Chicago, is like a compendium of every horrible idea from the 1980s. Imagine being forced to stand all through Communion (even afterwards) when those self-same ‘enlightened’ liturgists moved the SEQUENCE before the Alleluia to make sure congregations wouldn’t have to stand during it. (Even worse, everything about the SEQUENCE—including its name—means it should follow the Alleluia.) And imagine endlessly repeating “Alleluia” during Holy Communion at every single Mass. It was all part of an effort to convince people that Holy Communion was historically a procession (which it wasn’t).

    “Canonic” • Ralph Vaughan Williams
    Fifty years ago, Dr. Theodore Marier made available this clever arrangement (PDF) of “Come down, O love divine” by P. R. Dietterich. The melody was composed in 1906 by Ralph Vaughan Williams (d. 1958) and named in honor of of his birthplace: DOWN AMPNEY. The arrangement isn’t a strict canon, but it does remind one of a canon since the pipe organ employs “points of imitation.” The melody and text are #709 in the Brébeuf Catholic Hymnal.

    Did they simplify these hymn harmonies?
    Choirs love to sing the famous & splendid tune called “INNSBRUCK.” Looking through a (Roman Catholic) German hymnal printed in 1952, I discovered what appears to be a simplified version of that hymn. In other words, their harmonization is much less complex than the version found in the Saint Jean de Brébeuf Hymnal (which is suitable for singing by SATB choir). Please download their 1952 harmonization (PDF) and let me know your thoughts. I really like the groovy Germanic INTRODUCTION they added.

Random Quote

“Every medicine does not suit every stage of sickness; because the tonic given to those who are recovering from fever would be hurtful to them if given while yet in their feverish condition. So likewise Baptism and Penance are as purgative medicines, given to take away the fever of sin; whereas this sacrament [the Sanctissimum] is a medicine given to strengthen, and it ought not to be given except to them who are quit of sin.”

— Saint Thomas Aquinas Re: the EUCHARIST
