Pope Benedict XV (1854-1922)

To understand Benedict XV is to grasp a paradox: a pope without an army, without territory after the fall of the Papal States, seemingly powerless before the empires at war, yet who alone tries to raise a moral voice above the fray. His pontificate is that of spiritual authority confronted with the total violence of the emerging 20th century.

Where his predecessor Saint Pius X waged an internal doctrinal battle against modernism, Benedict XV inherited a Church torn not only by ideas but by borders: bishops, priests, and Catholic faithful fought on both sides of the front. The pope could not bless any flag without betraying Catholics on the other side. His foundational decision, taken in the earliest days, was to choose no side — not out of cowardice, but out of fidelity to the universality of the Church.^[10]

“The spectacle presented by Europe and indeed by the whole world, assuredly the most dreadful and mournful spectacle ever seen within the memory of man […]: each day the earth, drenched with new streams of blood, is covered with the dead and the wounded.”
— Benedict XV, encyclical Ad beatissimi Apostolorum, 1 November 1914, in the Holy See’s official French translation^[11]

This interpretive framework governs everything: impartiality, peace diplomacy, humanitarian work, and even the internal governance of the Church, where Benedict XV sought everywhere conciliation rather than condemnation. The major issues opened during his reign — the Code of Canon Law, missionary reform, defense of Scripture, the cause of Joan of Arc — each belong to a separate article; what belongs uniquely to Benedict XV is having embodied the moral authority of the Holy See in trial, and having prepared, through patient diplomacy, the international restoration of the papacy that his successors would inherit.

A Patrician Genoese Family

Giacomo Paolo Giovanni Battista della Chiesa was born on 21 November 1854 in Pegli, a seaside suburb of Genoa, into an old family of the Genoese nobility: his father was Marquis Giuseppe della Chiesa, his mother Marchioness Giovanna Migliorati, of the house that produced Pope Innocent VII (1404-1406).^[12] The paternal line, for its part, is traced by some genealogists back to Pope Callixtus II (1119-1124) — an asserted but unestablished kinship, to be received as a family tradition.^[13] Small in stature, frail, marked by a slight limp and one shoulder higher than the other, the child bore a modest physique throughout his life, to which the biographical notices attach the nickname “il piccoletto”, the little man.^[14]

At his father’s insistence, young Giacomo first pursued studies in law: he obtained his doctorate at the University of Genoa on 2 August 1875. But his ecclesiastical vocation was longstanding and persistent; his father finally relented on the condition that he study in Rome. He was ordained a priest on 21 December 1878 by Cardinal Raffaele Monaco La Valletta.^[15]

The Diplomat: Rampolla’s School

Entering the Pontifical Ecclesiastical Academy—the nursery of Holy See diplomats—della Chiesa was noted for his precision and discretion. In 1882, he accompanied the nuncio Mariano Rampolla del Tindaro to Madrid, becoming his trusted collaborator. This encounter was decisive: Rampolla, future Secretary of State under Leo XIII, shaped him into a consummate diplomat, attentive to detail, trained in patience and in the art of patient negotiation in the service of the Holy See.^[16]

When Rampolla was recalled to Rome and appointed Secretary of State in 1887, della Chiesa followed him and rose through the ranks of the Secretariat of State: first a simple drafter preparing the files (what is called in Rome a minutante), then undersecretary.^[17] He became one of the essential cogs in Leonine diplomacy, at a time when Leo XIII sought to lift the papacy out of the isolation imposed by the Roman Question.

Substitute of the Secretariat of State

In 1901, della Chiesa was appointed substitute (in Italian sostituto) of the Secretariat of State, that is, the right-hand man of the Secretary of State for current affairs. He held this key position for six years, until his appointment to Bologna in late 1907 — after twenty years of service at the heart of the Curia, which he had entered in 1887 in Rampolla’s wake.^[18][19] But the election of Pope Pius X in 1903, and the replacement of Rampolla by Cardinal Merry del Val, marked a change in climate: close to the former Secretary of State, della Chiesa’s Roman career plateaued.

Archbishop of Bologna (1907–1914)

On 18 December 1907, Pius X appointed della Chiesa Archbishop of Bologna, one of Italy’s most prestigious sees; he was consecrated on 22 December by the pope himself. Many saw this as a promotion-exile: the man of Rampolla was removed from the Curia by being entrusted with a major diocese.^[20] In Bologna, della Chiesa proved to be an exemplary pastor: systematic pastoral visits, care for the clergy, attention to the poor, doctrinal firmness but moderation of tone amid the antimodernist storm then shaking the Church.

As was customary, the Archbishop of Bologna usually received the cardinal’s red hat shortly after appointment. For della Chiesa, the wait lasted nearly seven years—a sign of distrust from part of Pius X’s entourage toward him.

Cardinal in extremis (May 1914)

It was only on 25 May 1914 that Pius X finally created him cardinal, assigning him the title of Santi Quattro Coronati.^[21] No one then suspected that this last-minute cardinal would become pope three months later. Pius X died on 20 August 1914, barely after the war had been declared; and it was this frail diplomat, promoted in extremis, whom Providence placed at the helm of the Church to weather the storm.

A Conclave Under Cannon Fire

Pope Pius X died on August 20, 1914, reportedly struck down by grief at seeing Europe plunge into war. The armies were already on the move: general mobilization had begun in early August. The cardinals converged on Rome under dramatic circumstances—some, held back by closed borders and requisitioned trains, would not arrive in time. Of the 65 cardinals, 57 participated in the vote.^[22]

The conclave opened on August 31, 1914, in a climate of absolute urgency: the Church needed a leader capable of speaking to a world in flames. Two directions clashed—continuing Pius X’s anti-modernist campaign, or returning to the flexible diplomacy of the Rampolla-Leo XIII era.

Elected on the Tenth Ballot, by One Vote

The vote was tight. Cardinal Pietro Maffi, Archbishop of Pisa, was the main rival to della Chiesa, considered too liberal by some; other candidates canceled each other out. On the tenth ballot, September 3, 1914, Maffi’s votes shifted to della Chiesa, who was elected — by a single vote, it is said, above the required quorum.^[23] Accounts report that, out of scrupulousness, some cardinals demanded a verification of the ballots to ensure the new pope had not voted for himself: he had not.

He took the name Benedict XV and was crowned on September 6, 1914, in the Sistine Chapel—a deliberately simple ceremony, without the usual pomp, due to the war.^[24] The tone of the pontificate was set from the start: austerity, gravity, rejection of display while the world bled.

Why the Name Benedict

The choice of name was no accident. Della Chiesa honored Benedict XIV (Prospero Lambertini), like him a former Archbishop of Bologna and one of the most learned and measured popes of the 18th century.^[25] The name Benedict also evokes Benedictine peace—pax—which the new pope would make the hallmark of his reign. Through this name, Benedict XV announced a line: scholarship, moderation, and peace, continuing tradition rather than breaking with it.

War as Mourning for Civilization

Two months after his election, on November 1, 1914, Benedict XV published his first encyclical, Ad beatissimi Apostolorum. It is a text of mourning as much as doctrine. The pope describes the war as an unprecedented moral catastrophe and calls for peace with restrained vehemence.

“Everywhere reigns the dark image of death: no day passes without new massacres being committed […], entire nations striving to destroy each other with refinements of horror.” — Benedict XV, Ad beatissimi Apostolorum, November 1, 1914^[26]

The pope denounces the deep causes of the conflict: the forgetting of God, class struggle, greed for material goods, the erosion of moral authority. For him, the war was not a mere diplomatic accident but the symptom of a civilization that had lost its Christian soul. It is in this context that the press would lastingly associate with his condemnation of the war the phrase describing the conflict as the “suicide of civilized Europe” (in English “the suicide of civilized Europe”) — a phrase found neither in the Latin nor in the official French translation of Ad beatissimi.^[27][28]

Peace Among Catholics: “Christian is My Name, Catholic My Surname”

Ad beatissimi does not only address peace between nations: it also demands peace within the Church. Under Pius X, the fight against modernism had degenerated, in some quarters, into a witch hunt: zealous Catholics claimed the title of “integrals” (integrists) to distinguish themselves from alleged lukewarm believers, denouncing without proof the orthodoxy of priests, theologians, and exegetes.

Benedict XV confirmed the condemnation of modernism—there was no doctrinal break—but he forbade these partisan labels that divided the faithful.

“There is no need of qualifiers to signify the profession of Catholicism; for each it suffices to say: Christianus mihi nomen, catholicus cognomen. Let one only strive truly to live up to this name by one’s deeds.”
— Benedict XV, Ad beatissimi Apostolorum, November 1, 1914, § 28, in the Holy See’s official French translation^[29]

This passage is the key to all of Benedict XV’s internal governance: to keep intact the received doctrine but disarm the factions that tear themselves apart in its name. It is the ecclesial application of the same conviction that inspired his diplomacy: to reject the logic of camps mutually excommunicating each other.

Neither "Pope Boche" nor "French Pope"

Benedict XV’s position during the war is constantly caricatured. He is criticized for his “neutrality” as if it were indifference. In reality, the pope carefully distinguishes political neutrality (which is disengaged) from spiritual impartiality (which loves all belligerents equally and speaks to them all). As the common Father of all Catholics, he cannot publicly name a culprit without breaking with half of his children.^[30]

The result is that he is suspected by both sides: French propaganda nicknames him “the Pope Boche”, German propaganda “the French Pope” (Franzosenpapst).^[31] This double accusation, which wounds him, is paradoxically the proof of his integrity: an arbitrator hated by both camps is rarely a collaborator of either.

Why Silence to Act More Effectively

Benedict XV’s silence on the respective guilt of the nations is not indifference: it is a moral calculation in the service of effectiveness. By refusing to condemn either belligerent by name, he preserves the possibility of being heard by all, thus able to mediate and aid. A public condemnation would have closed the chancelleries’ doors and dried up humanitarian channels.

This stance costs him dearly in immediate popularity, but it allows him to accomplish, in the shadows, the most concrete work of his pontificate: saving lives on both sides of the front.

Benedict XV’s impartiality only makes sense because it leads to action. Throughout the war, the Holy See becomes a vast charity office serving victims without distinction of nationality or religion.

The effort is so considerable that it weighs heavily on the Holy See’s finances: biographical tradition holds that at Benedict XV’s death, the Vatican’s coffers were nearly empty, drained by this wartime charity.^[33] This concrete generosity explains the extraordinary posthumous gratitude shown to him even by non-Christians — foremost among them the Muslims of Constantinople.

The Seven Proposals

After three years of carnage and following long secret diplomatic efforts, Benedict XV addressed a Peace Note on August 1, 1917 to the leaders of the belligerent peoples. It is the most famous and courageous act of his pontificate. The pope replaces the logic of total victory with a logic of negotiated justice.

The seven pillars of the Note can be summarized as follows:

1. The moral force of right must replace the material force of arms.
2. Simultaneous and reciprocal reduction of armaments.
3. Institution of an international arbitration, with sanctions against any state refusing to comply.
4. Freedom and community of the seas.
5. Mutual renunciation of war indemnities (reparations).
6. Mutual restitution of occupied territories — notably the evacuation and restoration of Belgium, guaranteed in its independence.
7. Examination of territorial claims in a spirit of conciliation and fairness.^[34]

The pope asks therein, in substance, that the moral force of law be substituted for the material force of arms.^[35]

The phrase that made the document immortal is the characterization of the war as an “useless massacre” (inutile strage): a slaughter disproportionate to the political aims pursued.^[36]

General Rejection

The Note was rejected by all the major belligerents. The Allies saw it as a maneuver favorable to the Central Powers (since it renounced victory and reparations); the Germans, confident of victory after Russia’s collapse, also refused to give up their conquests. Only Austria-Hungary, Catholic and exhausted, received it with genuine interest.^[37][38] American President Woodrow Wilson rejected it, judging it impossible to negotiate with the governments of Berlin and Vienna.

Yet, a few months later, Wilson’s Fourteen Points (8 January 1918)—disarmament, freedom of the seas, League of Nations, fair settlement of claims—showed several convergences with the pontifical Note of 1 August 1917, without any direct influence being established. History would especially vindicate Benedict XV on one crucial point: his rejection of punitive reparations, which the Treaty of Versailles would make one of the seeds of the next war.^[39]

Exclusion from Versailles (Treaty of London, 1915)

If the pope could not influence the peace, it was not only because his Note was rejected. As early as 1915, by Article 15 of the Treaty of London—the secret agreement by which Italy entered the war on the side of the Entente—the Allies committed to supporting Italian opposition to any participation of the Holy See in future peace negotiations.^[40] Italy, anxious to avoid reopening the “Roman Question,” thus secured the exclusion of the pope from the Versailles table even before pontifical mediation could take place. Benedict XV feels the humiliation: the papacy is excluded from the settlement of the greatest conflict in history. But he draws a lesson of diplomatic patience from it: it is by quietly multiplying bilateral relations that the Holy See will, after him, regain its place in the concert of nations.

Maintaining anti-modernism, breaking integrism

The pontificate of Benedict XV illustrates a fidelity without rupture: no break with the doctrinal battle of Pope Saint Pius X, but a correction of the excesses that had disfigured it — keeping the received doctrine intact while changing methods. The pope maintains the Anti-Modernist Oath and the condemnation of the errors of Pascendi; he does not reopen any breach to modernism.^[41][42]

But he puts an end to the drift of the Sodalitium Pianum (the “Sapinière”), a network of clandestine informants founded by Bishop Umberto Benigni to spy on priests and bishops suspected of modernism. This secret police, which had cast suspicion on genuine Catholic scholars, is definitively suppressed by order of Benedict XV: the decision was made on November 25, 1921, and executed on December 8, 1921.^[43] The discovery of internal documents completed the exposure of its methods of secret surveillance.^[44]

Benedict XV’s lesson is clear: the faith is defended without denunciation or internal terror. Truth does not need spies.

Spiritus Paraclitus (1920): the inerrancy of Scripture

On September 15, 1920, on the occasion of the fifteenth centenary of the death of Saint Jerome, Benedict XV published the encyclical Spiritus Paraclitus, one of his most important doctrinal texts. Through the praise of the great translator of the Vulgate, the pope reaffirms, against modernist tendencies, the traditional doctrine of the divine inspiration and inerrancy of all Scripture.^[45]

The encyclical follows directly in the line of Providentissimus Deus by Leo XIII (1893). It explicitly rejects the theory — then advanced by some exegetes in the supposed name of Saint Jerome — that would limit inerrancy to only the “religious” truths of Scripture, abandoning its historical or scientific affirmations to error.

The encyclical thus opposes, in substance, to those who restrict the guaranteed divine truth to religious matters alone, the example of Saint Jerome, who held all of the holy Books to be free from all error.^[46]

This text makes Benedict XV one of the magisterial guardians of biblical inerrancy at the dawn of the 20th century — a decisive point for anyone wishing to understand the Catholic position on the authority of Scripture in the face of rationalist exegesis.

The 1917 Code of Canon Law

On May 27, 1917, Pentecost Sunday, Benedict XV promulgated, through the constitution Providentissima Mater Ecclesia, the first Code of Canon Law (Codex Iuris Canonici), which came into force on May 19, 1918, Pentecost Sunday of the following year.^[47] For the first time, the law of the Church — until then scattered in a vast mass of decrees, conciliar canons, and decretals — was gathered into a single, clear, and systematic code of 2,414 canons.^[48]

The work, begun under Pius X and directed by Cardinal Pietro Gasparri — whom Benedict XV retained as Secretary of State — bears the name of the “Pio-Benedictine” Code: conceived under Pius X, promulgated by Benedict XV. It is one of the most enduring acts of governance of the pontificate: this code governed the Latin Church until its revision by John Paul II in 1983.

Maximum illud (1919): The Charter of Modern Missions

On November 30, 1919, Benedict XV issued Maximum illud, regarded as the founding charter of modern missiology. The war had just revealed how much Catholic missions, dependent on European colonial powers, had suffered from their subjugation to national interests. The pope initiated a profound reform.^[49]

Two principles dominate. First, the rejection of missionary nationalism: the missionary does not work for his earthly homeland but for the Kingdom of Christ.

Therein the pope warns against the missionary who would labor to increase the prestige of his homeland rather than the Kingdom of Christ.^[50]

Second, the promotion of a fully formed indigenous clergy, capable of taking charge of their local Church instead of remaining forever dependent on foreign missionaries.

He then asks every mission superior to recruit and train local candidates for the sacred ministry as a priority.^[51]

The text also demands from missionaries a genuine knowledge of local languages and cultures. Its influence would be immense: Pius XI, Pius XII, and John Paul II would invoke it, and Pope Francis solemnly celebrated its centenary in 2019. Maximum illud is the act by which Benedict XV decolonized the very idea of mission.^[52]

The Congregation and the Institute for the Eastern Churches

Benedict XV’s concern for universality also led him to the Eastern Catholics. In 1917, he established the Congregation for the Eastern Churches as an autonomous dicastery and founded the Pontifical Oriental Institute in Rome, dedicated to the study of the traditions, liturgies, and law of the Eastern Churches.^[53] In a Europe torn apart by war and where multinational empires were collapsing, this was a declaration that the Catholic Church breathes with both her lungs, Latin and Eastern — a phrase John Paul II would take up in his encyclical Ut Unum Sint, § 54 (25 May 1995): “the Church must breathe with her two lungs”.^[54]

Regina Pacis and the Eve of Fatima

Unable as a diplomat to halt the war through chancelleries, Benedict XV turned to Marian prayer. On May 5, 1917, after exhausting human means, he issued an urgent letter entrusting the cause of peace to the Virgin Mary and ordering his Secretary of State to add to the Litany of Loreto the invocation “Queen of Peace, pray for us” (Regina Pacis, ora pro nobis).^[55]

Therein the pope invites, in substance, the whole world to raise to Mary, Mother of mercy and almighty by grace, a loving and confident supplication.^[56]

The coincidence is striking: eight days after this pontifical appeal to the Queen of Peace, on May 13, 1917, the Virgin appeared for the first time to three children at Fatima, Portugal — precisely to ask for prayer and conversion for the sake of peace. The full account of the apparitions is found in the dedicated article; but Benedict XV’s gesture providentially falls on the eve of one of the century’s greatest Marian events.

Joan of Arc, Margaret Mary: Holiness and French Reconciliation

Benedict XV’s pontificate was marked by major canonizations. On May 13, 1920, he inscribed Margaret Mary Alacoque, apostle of the Sacred Heart, and Gabriel of Our Lady of Sorrows into the catalogue of saints. Three days later, on May 16, 1920, before more than sixty thousand faithful gathered at Saint Peter’s, he canonized Joan of Arc.^[57]

This canonization also had considerable diplomatic significance. France, following the 1905 Separation, had broken off relations with the Holy See; yet Joan of Arc is the national heroine par excellence, claimed by both Catholics and republicans. By canonizing her, Benedict XV offered France a ground for reconciliation. This rapprochement led to the restoration of diplomatic relations between Paris and the Vatican (French embassy to the Holy See), crowning the pope’s patient policy of appeasement.^[58][59]

Beyond France, Benedict XV multiplied bilateral contacts and restored the international prestige of the papacy, which the "Roman Question" had isolated. The number of states maintaining diplomatic representation with the Holy See increased during his pontificate from fourteen to twenty-seven.^[60][61] Where the powers had excluded him at Versailles, the pope patiently rebuilt, capital by capital, the network that would make the Holy See a respected actor on the world stage.

This diplomacy of patience is the other side, less spectacular but more enduring, of the apparent failure of the Peace Note: having been unable to impose peace, Benedict XV restored the voice of the Church in the concert of nations, a legacy inherited by Pope Pius XI and Pope Pius XII.

A Sudden End (January 1922)

In early January 1922, Benedict XV contracted the flu, which quickly developed into bronchopneumonia. Weakened by seven years of a taxing pontificate, he died in Rome on 22 January 1922, at the age of 67, after governing the Church for seven years and four months.^[62] His premature passing struck the Catholic world, which then discovered, in mourning, the extent of a long-discreet charity.

The conclave that followed elected, on 6 February 1922, Cardinal Achille Ratti, Archbishop of Milan, as Pope Pius XI — who would continue and expand several of the initiatives begun by his predecessor, from missions to diplomacy.

The Tomb and the Statue in Istanbul

Benedict XV is buried in the Vatican grottoes, beneath St. Peter’s Basilica. But the most eloquent tribute is not in Rome: it is in Constantinople (Istanbul). In the courtyard of the Cathedral of the Holy Spirit, the reference works report that a bronze statue was erected — at the initiative of the Turkish authorities of the time, of a Muslim country — in memory of the pope, in recognition of his aid to war victims without distinction of side or faith.^[63]

According to the English transcription reported by the reference works, the plaque would present him as the benefactor of all peoples without distinction of nationality or religion.^[64]

That a Muslim state honors a Catholic pope in this way is an almost unique testimony in history. It says better than any commentary what Benedict XV’s pontificate truly was: not a diplomatic failure, but a service to humanity recognized even by those who did not share his faith.

The Judgment of History

Long overshadowed between the austere figure of Pope Saint Pius X and the authority of Pope Pius XI, Benedict XV has been rehabilitated by recent historiography. He is now recognized as a clear-sighted and prophetic pope: clear-sighted about the horror of a war that chancelleries believed would be brief and glorious; prophetic about the dangers of a punitive peace.

The Encyclopædia Britannica sums up this wartime pontificate as the effort, by every means in its power, to end the conflict and alleviate its evils.^[65]

A diplomat trained by Rampolla, a faithful heir to the doctrine of Pius X but a reformer of its methods, of a charity that tradition says drained the Vatican’s coffers, Benedict XV remains the pope of the impossible peace — the one who, having been unable to stop the war, at least saved its victims and restored, for the future, the moral authority of the Apostolic See.

• Pope Saint Pius X — his predecessor, the pope of the anti-modernist struggle whose doctrine Benedict XV maintained while correcting its excesses.
• Pope Pius XI — his immediate successor, elected in 1922, who extended his missionary reform and diplomacy.
• Pope Leo XIII — the pope of Providentissimus Deus and the diplomatic school of Rampolla, whose heir Benedict XV was.
• Pope Benedict XIV — the scholarly Archbishop of Bologna whose name Giacomo della Chiesa took.
• Venerable Pius XII — the pope of the Second World War, confronted with the same drama of pontifical impartiality.
• Our Lady of Fatima — the 1917 apparitions, which occurred eight days after Benedict XV’s appeal to the Queen of Peace.
