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.

    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.

    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).

Random Quote

This was first breach in the walls of a fortress, centuries old, stoutly built, strong and robust, but no longer capable of responding to the spiritual needs of the age. [N.B. the “fortress” is a liturgy which nourished countless great saints.]

— Annibale Bugnini (19 March 1966)
