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.).

    “The Worm That Dieth Not”
    My pastor asked me to write a column for our parish bulletin with reflections on the sacred liturgy and church music. In my most recent article, I discuss “The Worm That Dieth Not.” At this website, you can access it conveniently; simply scroll down to the one dated 31 August 2025.

    A Nice Hymn In Spanish
    In my humble opinion, this is a really beautiful hymn in Spanish. If I practice diligently, I’ll be able to pronounce all the words properly. If you’re someone who’s interested in obtaining a melody only version (suitable for your congregational ORDER OF WORSHIP) you can steal that from this.

    “Music List” • 21st in Ordinary Time (Year C)
    Our choir returns on Sunday, 24 August 2025. Some have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for it, which is the 21st Sunday in Ordinary Time (Year C). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the spectacular feasts website. When it comes to the feast of the Assumption (15 August 2025), I have uploaded the music list for that Mass—but not the “bi-lingual” Mass in the evening (Spanish, Latin, and English) which has completely different music.

Quick Thoughts

    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).

    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.

    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.

Random Quote

Like all other liturgical functions, like offices and ranks in the Church, indeed like everything else in the world, the religious service that we call the Mass existed long before it had a special technical name.

— Rev. Adrian Fortescue (1912)
