We are very glad to share the news that His Eminence Raymond Cardinal Burke will celebrate a solemn pontifical Mass in St Peter’s basilica on October 25th, as part of this year’s Populus Summorum Pontificum pilgrimage to Rome. This Mass was the highlight of the annual pilgrimage event for several years, but was then forbidden for the last two. In addition, His Eminence Matteo Cardinal Zuppi, archbishop of Bologna and president of the Italian Bishops’ Conference, will once again celebrate a pontifical Vespers for the pilgrimage, this year in the ancient basilica of San Lorenzo in Lucina.
Let us be thankful to God that He has inspired such paternal charity in our Holy Father Leo, and pray that He may inspire him to restore the wise provisions of Pope Benedict XVI’s motu proprio Summorum Pontificum, from which the pilgrimage takes its name.Monday, September 08, 2025
Cardinal Burke to Celebrate Mass in St Peter’s Basilica for the Summorum Pontificum Pilgrimage

Regina Pacis, Ora Pro Nobis!
Gregory DiPippoOne of the few sensible changes made to the calendar in the post-Conciliar reform is the exchanging of the places (more or less) of two Marian feasts, those of the Immaculate Heart of Mary and of Her Queenship. Both of these were added to the general calendar by Pope Pius XII, the first in 1944, the second ten years later. The latter was originally assigned to the last day of May because of the popular custom of keeping May as a Marian month, even though there was no general Marian feast within it. The former was placed on the octave of the Assumption for no discernible reason, other than the fact that before it was put on the general calendar, some places kept it on the Sunday after the octave; but the Calced Carmelites, one of the first religious orders to adopt it, had it in the same place it was given in the Novus Ordo, on the day after the feast of the Sacred Heart.
As I am sure our readers know, the Holy Father Pope Leo asked that today be observed as a special day of prayer and fasting for the peace throughout the world. This made me think of a Marian title which has no formal liturgical expression, and so would be covered by the feast of Our Lady’s Queenship, which I am pretty certain is the reason why he chose today, “Queen of Peace.” This title was proclaimed by Pope Benedict XV when he added it to the Litany of Loreto in November of 1915, as the First World War was approaching its second Christmas.![]() |

Very Wise Words from Pope Leo about Polyphony in the Liturgy
Gregory DiPippoThis year, the Church is commemorating the fifth centenary of the birth of one of the greatest composers of liturgical music in her history, Giovanni Pierluigi da Palestrina (1525-94). Yesterday, in the Sala Regia of the Apostolic Palace, Pope Leo was present for an event in celebration of Palestrina, organized by the Cardinal Domenico Bartolucci Foundation. (Cardinal Bartolucci, himself a prolific composer, was also director of the Sistine Chapel Choir, and dedicated much of his life to preserving the tradition of the Roman school of polyphony embodied by his illustrious predecessor of the 16th century.) The Pope spoke about the use of sacred polyphony in the liturgy in words which should be very encouraging to those who work as Cardinal Bartolucci did to keep the precious heritage of our liturgical tradition alive, not just as music for concert performance, but as music for prayer. Those who believe that such music should be excluded from the liturgy because it does not foster “participation”, as it is so commonly and shallowly understood, would do well to consider these wise words, which are, of course, fully consonant with the Church’s long-standing tradition and teaching on the use of sacred music, and no less so with the words of the Second Vatican Council en regard.

Pope Leo Restores An Ancient Tradition (From 42 Years Ago)
Gregory DiPippoAt the end of this month, our Holy Father Leo XIV will celebrate the feast of Ss Peter and Paul as Pope for the first time. Our readers have perhaps read that the custom will be restored by which during the celebration of Mass in St Peter’s basilica, the pope blesses the pallia which are to be given to those who have lately been made metropolitan archbishops, and personally imposes it on them. In 2015, this custom was changed so that the pope blessed the pallia, but they were imposed on the archbishops back home by the local nuncio. It is difficult to think why this was thought to be necessary, or some kind of improvement, and I think it is a good thing that Pope Leo has undone it. The pallium Mass had become quite a festive occasion in Rome, and many of the new archbishops would be accompanied by large pilgrim groups from their dioceses. It will be nice if these kinds of pilgrimages flourish again.

A History of the Popes Named Leo, Part 5: The Medicis, Leo X and XI
Gregory DiPippoThis is the fifth installment of a series on the thirteen papal namesakes of our new Holy Father Leo XIV; click these links to read part 1, part 2, part 3 and part 4.
The tenth and eleventh Popes to bear the name Leo were both members of the Medici family, the ruling dynasty (at first de facto, later de jure) of Florence. Thanks to the family’s disastrous lack of concern for the Church’s laws about consanguineous marriage, Cardinal Alessandro de’ Medici was related to Leo X on both his father’s and his mother’s side, and took the name in honor of his relative. But since he died on the 27th day of his papacy, he is really more of a footnote to this series than anything else. He was born on this day in the year 1535, in the reign of another Medici, Clement VII, exactly 300 years before the birth of another Pope, St Pius X.

A History of the Popes Named Leo, Part 4: St Leo IX, and the Gregorian Reform
Gregory DiPippoThis is the fourth installment of a series on the thirteen papal namesakes of our new Holy Father Leo XIV; click these links to read part 1, part 2 and part 3.
The church of Rome and the papacy have usually been late-comers to the great movements of reform and renewal in the Church, and have just as often been themselves in dire need of reform and renewal. But eventually Our Lord’s prayer that Peter, being once converted, confirm his brethren, comes again to fulfillment, the papacy at last accepts the need for a reform, and becomes its most important leader. This pattern is exemplified by the career of St Leo IX (1049-54), whose papacy is the point at which Rome, so long caught up in the general decadence of the Church in the West, definitively embraced the cause of reform. To understand this, we must back up a bit and explain some history.

A History of the Popes Named Leo, Part 3: The 10th Century (Leo V-VIII)
Gregory DiPippoThis is the third installment of a series on the thirteen papal namesakes of our new Holy Father Leo XIV; click these links to read part 1 and part 2.
Four Popes named Leo reigned within a span of about 62 years in the 10th century; their reigns are all quite brief, and their careers for the most part so obscure that the precise dates of some of them are not even known, so this will be a short article. First, however, an historical and historiographical note.
The term “dark ages” is used and over-used by bad historians to mean broadly “any period after the fall of the Roman Empire when stuff happened that I dislike.” But if there is an age to which it can justly be applied, and especially in regard to the papacy, it is the 10th century. The Carolingian Empire had fractured, and was no longer the stabilizing political force it had been under Charlemagne. Western Europe was besieged on all sides: by the Vikings from the north, the Magyars from the east, and the Saracens everywhere that touched the Mediterranean. Even if the Popes of that era had been Saints on the model of men like the first Leo, it is hard to imagine that they would have been able to achieve much that we would look back on as exemplary. But many of them were very far indeed from being Saints, and the tenth century is the first in which there is no canonized or beatified pope.![]() |

Palestrina’s Motet for Papal Coronations, “Hic Nunc Est”
Gregory DiPippoThis was spotted on Twitter yesterday, a set of photos from the Mass which formally inaugurated the ministry of the newly-elected Pope Leo XIV, feliciter nunc regnantis.
The full text of the antiphon as given in the recording is as follows:
“Hic nunc est circus tuus, hae nunc sunt simiae tuae,
quas Dominus in sapientia sua Petro tradidit,
et per manus eius nunc tibi commendat.
Gaude in stultitia sanctorum,
laetare in tumultu gratiae,
nam per hos clamosos
regnum caelorum patefit.
This is now your circus, these are now your monkeys,
Whom the Lord in His wisdom handed over to Peter,
and though his hands, now commends to you.
Rejoice in the foolishness of the Saints (cf. 1 Cor. 3, 18-19),
be glad in the tumult of grace,
for through these noisy ones
the kingdom of heaven is laid open.”

A History of the Popes Named Leo, Part 2: Saints Leo II, III and IV
Gregory DiPippoThis is the second installment of a series on the thirteen papal namesakes of our new Holy Father Leo XIV; click here to read part 1.
St Leo II reigned for less than 11 months, from August of 682 to June of 683. The most important deed of his pontificate was the confirmation of the acts of the Sixth Ecumenical Council, the third to be held in Constantinople, which condemned the Monothelite heresy; being fluent in Greek as well as Latin, Leo personally made the official Latin translation of the council’s acts. At the Council of Chalcedon in 451, St Leo I’s letter was acclaimed with the words, “Peter has spoken through Leo,” and likewise at Third Constantinople, the intervention of Leo II’s predecessor St Agatho (through his legates) was acclaimed with the words “Peter has spoken through Agatho!” It is one of the oddities of hagiography that the latter has never been honored with a general feast day in the West, but is kept on the calendar of the Byzantine Rite. Leo II, on the other hand, was a Sicilian, and therefore born as a subject of the Byzantine Empire, but is not liturgically honored in the East.
The collection of papal biographies known as the Liber Pontificalis is practically the only source of information about him, and gives few other details of real interest. He was highly skilled in rhetoric and music, and noted for his love and care for the poor. He built a church in the area of Rome now known as the Velabro, dedicated to St Sebastian, and later also to St George, whence its common title “San Giorgio in Velabro.” (Because George is the patron of England, Leo XIII gave it to St John Henry Newman as his cardinalitial title.)![]() |

This painting was much admired for the cleverly designed figure on the far right, the woman with a water-jar on her head, who has just turned the corner, and opens her mouth in astonishment at the scene. ~ A few years prior to the commissioning of this painting, Pope Julius II and his architect Donatello Bramante had begun the process of replacing the ancient basilica of St Peter, then almost on the point of collapse.

A History of the Popes Named Leo, Part 1: Introduction, and St Leo I
Gregory DiPippoThe ancient Romans had a saying, “Nomen est omen – a name is a sign”, i.e., a presage about the person who bears it. Of course, this is not always or in all ways true; during my very sleepy teenage years, my mother used to joke that Gregory, which derives from the Greek word for “watchful”, was about as inappropriate a name as they come. But it is a tradition solidly grounded in the Sacred Scriptures, where there are many significant names, the greatest of all being, of course, the Holy Name of Jesus, which means “salvation”; and likewise, significant name changes, most notably that of St Peter.

It occurred to me, therefore, that it might be interesting to take a look at the histories of the Popes named Leo, especially since the new Pope himself has said that he chose his new name in reference to Leo XIII, who “in his historic Encyclical Rerum Novarum addressed the social question in the context of the first great industrial revolution. In our own day, the Church offers to everyone the treasury of her social teaching in response to another industrial revolution and to developments in the field of artificial intelligence that pose new challenges for the defense of human dignity, justice and labor.” (If His Holiness declares a crusade against so-called “artificial intelligence”, he shall find no more enthusiastic supporter than myself; and if he decides to expropriate the term “Butlerian jihad” for it, I shall cheer for him all the more loudly.)
First, some statistics. As of last week’s election, Leo is tied with Clement as the fourth most common papal name, behind John, Gregory and Benedict. Five of these, the first through fourth and the ninth, are Saints. Leos V-VIII reigned within a span of about 62 years in the 10th century, the first century in which there is not a single canonized Pope, but three of them for less than a year. The first eight lived before it was the custom for popes to take a new name upon their election, so Leo was their baptismal name.
Since that custom took root in the mid-11th century, there have been at various points some clear trends in the choices of name. From 1046 to 1145, thirteen of the eighteen Popes were “second of his name”, followed by eight “thirds” out of eleven from 1145 to 1227. From 1644-1774, there were 14 popes, all of whom were called either Innocent, Alexander, Clement, or Benedict. (Three of those names have not been used again since that period.) Seven of the twelve Piuses reigned within the 183-year span from 1775 to 1958, occupying almost 128 of those years.
Leo, however, has never been a fashionable name in that sense. The reign of St Leo IX was a watershed in the history of the papacy, and very much for the good, despite its relative brevity (five years and two months), but his name was not taken again for over four and a half centuries. XI called himself Leo in honor of X, who was related to him, and it then went into abeyance again for almost 220 years.

Pope Leo XIII (1878-1903) |
Almost every series I have ever planned for NLM has been revised along the way, but for now, the plan is to cover just Leo I, a titanically important figure, in this article, followed by the next three Sainted Leos, then the four who reigned in the 10th century, Leo IX, the two Medicis (X and XI), and the two in the 19th century, XII and XIII.
St Leo I was Pope from September of 440 to November of 461, the tenth longest reign in the Church’s history. He is one of three popes traditionally known as “the Great”, along with Ss Gregory I (590-604) and Nicholas I (858-67), and with the former, one of only two recognized as Doctors of the Church, although this honor was not accorded to him until 1754. He is the first pope of whose theological writings we possess a really substantial corpus, in the form of nearly 100 sermons and over 140 letters.
He was born in Rome ca. 400, and is said to have been of a Tuscan family, but we know nothing of his early life. As a deacon of the Roman church under the sainted Popes Celestine I (422-32) and Sixtus III (432-40), he was already a very prominent figure, and received letters from St Cyril, the patriarch of Alexandria, and the great monastic writer John Cassian. It has been speculated that he was the theological mind behind the mosaic program of the basilica of St Mary Major, built in the wake of the Council of Ephesus (431) as Pope Sixtus III’s response to the Nestorian heresy. He was elected to the papacy from the diaconate, a common event in those days, while on a mission as a peace envoy in Gaul.

The central section of the mosaic arch above the altar in the basilica of St Mary Major, ca. 432 AD, with the throne of Christ, (the motif known as an etimasia), Ss Peter and Paul, and the symbolic animals which represent the four evangelists. Below them, the inscription reads “Xystus (the original form of ‘Sixtus’) the bishop for the people of God.” The Apostles are dressed as Roman senators; paired with “the people of God” in the inscription, this makes for a Christian version of the formal name of the Roman state, “the Senate and the Roman people”, a declaration that the Christian polity will outlast the collapsing Roman polity. (Image from Wikimedia Commons by RightLeft Medieval Art, CC BY-SA 4.0.) |
Much of St Leo’s preaching and letter-writing was occupied with combatting the various heresies afflicting the Church in his time: not just the on-going Christological controversies, but also Pelagianism, and the Gnostic sects of the Priscillianists, who were growing in Spain, and the Manichaeans. (On discovering the existence of a group of the latter in Rome itself, he made the reception of the chalice at Mass mandatory as a way of chivying them out, since the Manichaeans abominated the consumption of wine.) Unsurprisingly, the authority of the chief of the Apostles, and of his successor, the bishop of Rome, is a frequent theme in his works, and the Roman Rite has traditionally read his sermons in the Divine Office on the various feasts of St Peter.
The Christological controversies entered a new phase during his pontificate with the invention of yet another new heresy in Constantinople. This was the creation of an abbot called Eutyches, which later came to be known as Monophysitism, the denial of the two natures, divine and human, in the one person of Christ. A second council was called together at Ephesus in 449, the infamous “latrocinium – robber-synod”, as Leo called it, in which Flavian, the orthodox patriarch of Constantinople, was subjected to such violence by the heretics that he died of his injuries not long afterwards. (He is venerated by the Church as a martyr.) Leo’s legates (one of whom, his archdeacon Hilarius, would succeed him as Pope) were forcibly prevented from reading his letter to the council, and barely escaped with their lives.
Leo himself immediately declared the council to be null and void, and wrote a letter to the emperor Theodosius II, demanding that he cease interfering with matters that fall under the authority of the Church and its bishops. Two years later, with the coming of a new emperor to the throne, and with the support of his wife, the Empress St Pulcheria, the orthodox faith was vindicated at the fourth ecumenical council, that of Chalcedon, at which Leo’s letter, known as the “Tome to Flavian”, was acclaimed with the words, “Peter has spoken through Leo.”
Contemplating the serene beauty of St Mary Major, it is difficult to imagine that when it was built, the Western Roman Empire was dangerously unstable, and close to its end. Rome had already been sacked by the Visigoths in 410, the first time it had been attacked by a foreign enemy in 800 years. In 452, just one year after the Council of Chalcedon, the Huns under Attila entered Italy, and after successfully plundering Aquileia, Milan and Pavia, turned their sights towards the capital. The military was powerless to oppose them, and it was the Pope to whom the emperor and senate turned to intervene. Leo headed north and encountered Attila near Mantua; the exact words of their meeting have not been recorded, but he was somehow able to persuade the Hun to leave Italy in exchange for a tribute. (A later tradition, repeated in the breviary, and often represented in art, but completely unhistorical, has it that the Apostles Peter and Paul appeared over Leo with swords in their hands as a way of warning Attila off.)

When the Vandals arrived at the gates of Rome three years later, Leo was unable to persuade them to leave off as he had Attila, but he did at least get them to refrain from massacring civilians and from burning the city. The remaining six years of his reign were much occupied with repairing the ensuing damage, especially to the churches, and to recovering the captives whom the Vandals had taken with them back to Africa. The Liber Pontificalis records that he donated new silver vessels to the churches of Rome after the sack, and renovated the “Constantinian basilica”, i.e., the cathedral of Rome, not yet called St John Lateran, as well as the basilicas of Ss Peter and Paul, establishing a monastery at the former.
The addition of the words “sanctum sacrificium, immaculatam hostiam” to the Canon is traditionally ascribed to him, but it must be said that the liturgical notices given in the Liber Pontificalis are quite unreliable. The oldest collection of Roman liturgical texts, a manuscript preserved in the capitular library of the cathedral of Verona, contains several prayers which are unmistakably based on his sermons. For this reason, its discoverer, a canon of Verona named Giuseppe Bianchini (1704-64), called it the “Leonine” sacramentary, but it is not a sacramentary, and was certainly compiled rather later than Leo’s time.

Pope St Leo I, by Francisco Herrera the Younger (1627-85) |
Despite his importance, devotion to Pope Leo as a saint, both as formally expressed in the liturgy and on a popular level, has never been very prominent, especially in comparison with St Gregory. His feast day is missing from many of the earliest liturgical books of the Roman Rite, he is represented far less often in art, and, as noted above, he was not declared a Doctor of the Church until the mid-18th century. He is, however, one of the few Roman popes celebrated in the Byzantine Rite, on February 18th. In the West, the traditional day of his feast is April 11th, which is believed to be the date of one of the translations of his relics, although there is some uncertainty on this point. In the post-Conciliar Rite, his feast is kept on November 10th, the anniversary of his death. His relics are in an altar in the southwest corner of St Peter’s basilica; those of Ss Leo II, III and IV, who will be the subjects of the next article in this series, are together in the altar right next to it on the left.
