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.”

Difference between the Two Priesthoods

Dr. Peter Kwasniewski · November 13, 2014

0319_Kwasni-96-LG N THIS POST, I would simply like to share two excellent but little-known texts from the Magisterium—one from Pope Pius XII on November 2, 1954 (in which he also quotes liberally from his great 1947 encyclical on the liturgy, Mediator Dei), and the other from the Congregation for the Doctrine of the Faith in 1973.

Here is what Pope Pius XII said on November 2, 1954, to cardinals, archbishops, and bishops gathered in Rome for ceremonies in honor of Our Lady:

THERE ARE SOME who have not ceased claiming a certain true power to offer sacrifice on the part of all, even laymen, who piously assist at the sacrifice of the Mass. Opposing them, We must distinguish truth from error, and do away with all confusion. Seven years ago, in the same Encyclical We just quoted, We reproved the error of those who did not hesitate to state that Christ’s command, “do this in remembrance of Me,” “refers directly to the entire assembly of the faithful, and only afterwards did a hierarchical priesthood follow. Hence, they say, the people possess a true sacerdotal power, the priest acts only on an authority delegated by the community. Wherefore they think that ‘concelebration’ is the true Eucharistic sacrifice, and that it is more fitting for priests and people together to ‘concelebrate’ than to offer the Sacrifice in private, with no congregation present.” We also recalled to mind, in that Encyclical, in what sense the celebrating priest can be said “to take the place of the people”; namely “because he bears the person of Jesus Christ our Lord, Who is the head of all the Members, and offers Himself for them; thus the priest goes to the altar as a minister of Christ, subordinate to Christ, but ranking above the people. The people, however, since in no way do they bear the person of our Divine Redeemer, and are not mediators between themselves and God, cannot in any way share in sacerdotal rights.”

On the other hand, it should not be denied or called in question that the faithful have a kind of “priesthood,” and one may not depreciate or minimize it. For the Prince of the Apostles, in his first Letter, addressing the faithful, uses these words: “You, however, are a chosen race, a royal priesthood, a holy nation, a purchased people” (1 Pet. 2:9); and just before this, he asserts that the faithful possess “a holy priesthood, to offer spiritual sacrifices, acceptable to God through Jesus Christ” (ibid. 2:5). But whatever is the full meaning of this honorable title and claim, it must be firmly held that the “priesthood” common to all the faithful, high and reserved as it is, differs not only in degree, but in essence also, from priesthood fully and properly so called, which lies in the power of offering the sacrifice of Christ Himself, since he bears the person of Christ, the supreme High Priest.

As if to further develop these thoughts, the Congregation for the Doctrine of the Faith issued an instruction in 1973 entitled Mysterium Ecclesiae, which addressed many disputed questions of that turbulent time, including the nature of the ordained ministry. (The internal quotations are taken from the Second Vatican Council’s Dogmatic Constitution on the Church, Lumen Gentium.)

Christ the Lord, the High Priest of the new and everlasting covenant, wished to associate with His perfect priesthood and to form in its likeness the people He had bought with His own blood (cf. Heb. 7:20-22, 26-28; 10:14, 21). He therefore granted His Church a share in His priesthood, which consists of the common priesthood of the faithful and the ministerial or hierarchical priesthood. These differ from each other not only in degree but also in essence; yet they are mutually complementary within the communion of the Church.

The common priesthood of the laity, which is also rightly called a royal priesthood (cf. 1 Pt. 2:9; Rev. 1:6; 5:9ff.) since through it the faithful are united as members of the messianic people with their heavenly King, is conferred by the sacrament of Baptism. By this sacrament “the faithful are incorporated into the Church and are empowered to take part in the worship of the Christian religion” in virtue of a permanent sign known as a character; “reborn as children of God they are obliged to profess before men the faith which they have received from God through the Church.” Thus those who are reborn in Baptism “join in the offering of the Eucharist by virtue of their royal priesthood. They likewise exercise that priesthood by receiving the sacraments, by prayer and thanksgiving, by the witness of a holy life, and by self-denial and active charity.” […]

Priests, acting in the person of Christ the Head, offer this Sacrifice in the Holy Spirit to God the Father in the name of Christ and in the name of the members of His Mystical Body. This sacrifice is completed in the holy supper by which the faithful, partaking of the one body of Christ, are all made into one body (cf. 1 Cor. 10:16ff.).

    Pipe Organ “Answers” in Plainsong?
    In 2003, I copied a book by Félix Bélédin (d. 1895), who was titular organist—from 1841 to 1874—at the Cathedral of Saint John the Baptist in Lyon (France). In 2008, we scanned and uploaded the book to the Lalande Online Library. Nobody knows for sure when the book was published; some believe it first appeared in the 1840s. In any event, one who examines this excerpt, showing GLORIA IX might wonder why it says the organ answers in plainsong. However, the front of the book explains, telling the organist explicitly when to “respond in plainchant.” This is something called organ alternatim. Believe it or not, the pipe organ would take turns with the choir, playing certain texts instrumentally instead of having them sung. I’m not very well-versed in this—pardon the pun—but if memory serves, ORGAN ALTERNATIM was frowned upon by the time of Pope Saint Pius X. Nevertheless, French organists kept doing it, even after it was explicitly condemned as an abuse.

    Music List • (5th Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 5th Sunday of Lent (22 March 2026). If such a thing interests you, feel free to download it as a PDF file. Traditionally, this Sunday was called ‘Passion’ Sunday. Starting in 1956, certain church leaders attempted rename both ‘Passion’ Sunday and ‘Palm’ Sunday—but it didn’t work. For example, Monsignor Frederick McManus tried to get people to call PALM SUNDAY “Second Passion Sunday”—but the faithful rejected that. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    Music List • (Holy Thursday, 2026)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Holy Thursday, which is 2 April 2026. If such a thing interests you, feel free to download it as a PDF file. I’m not sure I’ve ever heard a more piercingly beautiful INTROIT, and I have come to absolutely love the SATB version of ‘Ubi cáritas’ we are singing (joined by our burgeoning children’s choir). I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

Quick Thoughts

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

    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.

    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.

Random Quote

“The choir shall henceforth sing or say no anthems of our Lady or other Saints, but only of our Lord, and then not in Latin; but choosing out the best and most sounding to Christian religion they shall turn the same into English, setting thereunto a plain and distinct note for every syllable one: they shall sing them and none other.”

— 1548 Edict of King Edward VI (a heretic) for Lincoln Cathedral
