Positive Message from a Catholic Priest

Today, we received this wonderful message from a Catholic Priest: I want to say thank you for everything you have done to bring back the sense of the sacred in The liturgy. We are going through a liturgical renewal here in the parish where I was assigned as a parochial vicar. I’ve only been a […]

Pentecost Melody Added

Let it be known: I have added the Pentecost melody (“Veni Creator Spiritus”) to the Seasonal Benediction website. I am slowly adding all the different melodies for the “O Salutaris Hostia”—so we can be seasonally appropriate during Benediction of the Blessed Sacrament.

From a Catholic priest…

Regarding the CCW mailing list, a priest (Father E. J.) wrote to us yesterday: “Sometime ago, you wrote something along the lines that none of your emails are copies or merely pitches; each one is individual. I respect you so much for that. I don’t always get to read through them, but they remain in […]

    Oldest Latin Eucharistic Hymn
    The Church’s oldest Latin Eucharistic hymn is featured in the Brébeuf Hymnal. Indeed, the legendary Father Adrian Fortescue made a translation of it—matching the original’s meter—which was elevated by the Brébeuf team. For years, we’ve been working on a Spanish hymnal: “Cantoral del Padre Antonio Daniel.” The progress has been slow but steady, and we encourage anyone fluent in Spanish to consider joining the proofreading team. A few days ago, my wife helped me record a rehearsal video for this Spanish version of the Church’s oldest Latin Eucharistic hymn.

    Rare Plainsong Accompaniments
    Our contributor, Veronica Brandt, went deep into Australia to take photographs of organ accompaniments for Gregorian Chant. Some consider these peculiar PLAINSONG ACCOMPANIMENTS—with 3-part harmonies by Barcelona Cathedral organist, Father Josep Muset i Ferrer—to be the rarest in the world. Click here to learn more. Thanks Veronica! 😊

Quick Thoughts

    “Reader Feedback” • 22 June 2026
    A reader wrote to us from Virginia: “I really appreciate the 23 harmonizations that you posted on CORPUS CHRISTI WATERSHED for the Daily, Daily, Sing to Mary hymn. I hope to find willing voices in our small Schola Cantorum to try the three-voice version. Carry on, sir! You’re doing the Lord’s work.” While we don’t know this gentleman personally, we note that he earned a Ph.D. (which demonstrates that our blog has something for everybody). 😊

    Time and Again We Are Asked…
    John Baptist Singenberger (d. 1924) was a central figure of Catholic Church music. In this utterly fascinating excerpt (Single-Page PDF), Singenberger writes: Time and again we are asked: “Is the Gregorian chant to be accompanied by the organ?” As a young student in Saint Gall, Singenberger befriended SEBASTIAN GEBHARD MESSMER, the future Archbishop of Milwaukee (Wisconsin). The two graduated together in 1861. The school they attended (Saint George’s Seminary) was a “seminary”—but in the older European sense. In other words, it provided a classical education without necessarily leading to ordination. Singenberger remained a layman his whole life, but Messmer was eventually made archbishop—by Pope Saint Pius X—of the very archdiocese in Wisconsin where Singenberger would spend his American career, giving him a powerful ecclesiastical ally.

    “Reminder” — Month of June (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). Since we were founded in 2006, not one of our board members has ever accepted any remuneration whatsoever—not a penny. We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.

Random Quote

“Iconographic tradition has theologically interpreted the manger and the swaddling cloths in terms of the theology of the Fathers. The child stiffly wrapped in bandages is seen as prefiguring the hour of his death: from the outset, he is the sacrificial victim, as we shall see more closely when we examine the reference to the first-born. The manger, then, was seen as a kind of altar.”

— Pope Benedict XVI (2012)
