Pope Boniface VI (896)

A fifteen-day pontificate, but not an insignificant one

Boniface VI left no encyclical, no council, no doctrinal definition, no notable pastoral act. Jaffé's Regesta Pontificum Romanorum records no letter, charter, or privilege under his name, and no homily has come down to us: in fifteen days, he materially had no time to impress any direction upon his policy.^[10][11] From the strict point of view of Church governance, these fifteen days are empty: the sources preserve no trace of any synod held, any bishop consecrated, or any liturgical decision imposed.

The importance of the case lies elsewhere. Boniface VI is the revealer of a longer crisis, opened with the pontificate of Formosus and closed only by John IX. He belongs to the most violent phase of what historians would later call the saeculum obscurum, the "dark century", of Rome: a century during which the papal election was captured by urban factions, aristocratic families, and foreign forces, without interrupting the apostolic succession.^[12]

To read Boniface VI only as a scandal is to miss what he teaches. To read his short reign as a negligible detail is also to miss what he teaches. The proper Catholic perspective is intermediate: a real pope, a fragile pontificate, a canonically irregular election, and an institution strong enough to absorb the incident without breaking the Petrine chain.

The revealer of the Roman crisis of April 896

When Formosus died on April 4, 896, Rome was still politically shaken by the imperial coronation of Arnulf of Carinthia celebrated six weeks earlier by the same Formosus.^[13] The Spoletan party led by Lambert and the imperial widow Ageltrude had not forgiven this Carolingian consecration; Arnulf, struck by paralysis on his return journey, was no longer able to impose his arbitration.^[14] The city hesitated between two camps: a German governor, Faroldo, who administers Rome on behalf of Arnulf while imperial garrisons hold the city, and Spoletan military pressure from the south.^[15]

It was in this political vacuum that the Romans acclaimed Boniface VI. The speed of this election, its popular character, and the absence of a clear synodal procedure are not neutral: they betray a Roman Church failing to follow its own rules. Treccani speaks of a man elected a furor di popolo, a phrase taken from the acts of the 898 council.^[16]

The incident was not isolated. During the saeculum obscurum alone, several elections were contested, some popes were violently removed, and the papacy would only regain canonical control of its own elections with the reforms of the 11th century, notably the decree of Nicholas II in 1059 reserving the election to the cardinals.

A case study in pontifical canon law

The Boniface VI case raises a precise legal question. Can a man twice canonically subjected to deposition from orders (depositio ab ordine) — loss of both clerical dignity and exercise of function — validly be elected pope? The ancient Church had clearly answered no: prior absolution and regular reinstatement were necessary.^[17] The Roman council of 898 merely drew this consequence.

This then opens a second, more complex question: if the election is canonically null, is the pontificate dogmatically null? No known dogmatic definition settles this point: the Roman council of 898 ruled on the juridical regularity of the election, not on the dogmatic value of the pontificate. The Church has taken a practical path: maintaining Boniface VI in the official list, rendering him no cult, and drawing from his case preventive legislation on future elections.

This is a prudent position. It protects the visible continuity of the See of Peter, without endorsing the concrete conditions of the election. Catholic theology of the papacy has never affirmed that every pope was well elected, well alive, or well dead. It affirms that the chair of Peter remains, even when its momentary occupant is unworthy or contested.

Table of Witnesses

The documentary file is deliberately brief. It is insufficient to write a true spiritual biography of Boniface; it suffices to write a rigorous article on three axes: canonical antecedents, Roman crisis of 896, and canonical reception at the 898 council.

The Holy See: Minimal Chronology

The official Vatican record gives its markers in minimal form: Boniface VI is the 112th pope there, born in Rome, with 26 April 896 as the single date.^[18] No detailed biographical notice appears on the official page, which merely lists his name in the pontifical sequence between Formosus and Stephen VI.

This sobriety is telling. The Holy See neither glorifies Boniface VI’s memory nor erases it. It includes him in the apostolic list with the same chronological coordinates as other popes, without honorary title or spiritual qualification. The canonical title of the article must reflect this sobriety: Pope Boniface VI (896), without qualifier.

Some generalist lists give a variant, April 4–19, 896 — fifteen days counted from the death of Formosus — but modern chronology retains April 11–26: this is the dating of Treccani, which places the consecration "con ogni probabilità" on April 11, and not the one shown on the Holy See record, which bears only the single date of 26 April 896.^[19][20][21]

The Liber Pontificalis: The Brief Notice

The notice in the Liber Pontificalis is just a few lines, in the critical edition by Louis Duchesne, vol. II, p. 228.^[22][23] It states that Boniface was Roman (natione Romanus), that he sat fifteen days, that he died struck by the disease of gout (podagrico morbo correptus), and was buried at the portico of the popes of the old St. Peter’s Basilica.^[24][25] The name of his father — Hadrian, bishop of an unknown see — does not come from this notice, which calls him only Roman: it is the historian tradition that reports it.^[26]

This notice is valuable for two reasons. It was written close in time, within the very circle of the 10th-century Roman curia. And it does not seek to glorify Boniface: the very sobriety of his memory confirms the credibility of the text.

"Boniface, a Roman by birth, sat fifteen days. Struck by the disease of gout, he was buried in the portico of the popes." — Liber Pontificalis, notice Bonifatius VI, ed. Duchesne, vol. II, p. 228 (translation based on the Latin excerpts — natione Romanus, podagrico morbo correptus, in porticu pontificum — quoted by Treccani)^[27][28]

Treccani: The Modern Portrait

The notice by Paolo Bertolini in the Enciclopedia dei Papi is today the most useful scholarly synthesis.^[29] It recalls the tumultuous past of the future pope, his two depositions as subdeacon then as priest for immoral conduct, his later reinstatement in the clergy, and the German presence in Rome at the time of his election, with a German governor named Faroldo acting on behalf of Arnulf, the city being held by imperial garrisons.

Treccani also emphasizes that, according to the acts of the Roman council of 898 — constitution III in the numbering it follows — this priest with a dubious past "fu eletto a furor di popolo nel corso di una sommossa" (text verified word-for-word on October 4, 2026): an election therefore juridically irregular.^[30] The retrospective condemnation is not a late polemical coloring; it appears in the conciliar documentation preserved for this synod.

Catholic Encyclopedia and Anglo-Saxon Notices

The notice by Thomas Oestreich in the 1907 Catholic Encyclopedia, reproduced by New Advent, gives the most widely disseminated English formulation: Boniface was a Roman, elected in 896 by the Roman faction in a popular tumult to succeed Formosus, twice deposed as subdeacon then as priest, and his election was declared null by the Roman council of 898 under John IX.^[31]

The article also presents the dual tradition on his death: either gout according to the Liber Pontificalis, or violent eviction by the Spoletan party wishing to install Stephen VI. Later notices in Britannica and Encyclopedia.com follow this structure.^[32]

A Roman Son of a Bishop

The Liber Pontificalis presents Boniface as natione Romanus, a Roman by birth.^[33] The historian tradition, taken up by Treccani, adds that he was the son of a bishop named Hadrian, whose exact see is not identified.^[34] The paternal mention is significant: it places the future pope in a clerical environment, where the transmission of ecclesiastical offices from father to son was not yet strictly forbidden at the end of the 9th century, despite longstanding disciplinary reminders.

Latin priestly celibacy was not imposed all at once. The decisive disciplinary turning point came with the Lateran councils: Lateran I (1123, can. 21) forbade major clerics marriage and cohabitation, then Lateran II (1139, can. 7) declared invalid marriages contracted by clerics after their ordination; the Council of Trent (1545-1563) would only reaffirm this discipline. The case of Boniface VI illustrates, among many others, the gap between canonical ideal and Roman practice in the 9th century.

The First Deposition as Subdeacon

All sources agree on one point: Boniface was deposed twice before his election as pope, each time for immoral conduct, that is, for serious personal fault in the order of morals.^[35][36][37]

The first time, he was a subdeacon: a minor order below the diaconate, which already imposed ecclesiastical continence and a certain way of life in Rome. A deposition at this level means two things: the legal loss of the order received and a return to the lay state, with canonical opprobrium. The details of the incident have not been preserved; the notices do not specify the name of the pope or authority who pronounced the sentence.

The Second Deposition as Priest

The second episode is more serious. Boniface was reinstated in the clergy, ordained up to the presbyterate, then again deposed for immoral conduct. Encyclopedia.com specifies that this suspension concerned his unworthy conduct precisely, and that he had not been canonically reinstated at the time of his election as pope.^[38]

This point would legally seal the sentence of John IX in 898. An election to the pontificate presupposes, as a minimal prerequisite, the regular enjoyment of ecclesiastical orders. Yet Boniface, on April 11, 896, was still canonically under the effect of the second deposition.

"he had been twice suspended, as a subdeacon and again as a priest, because of unworthy conduct, and had not been canonically reinstated." — A. J. Ennis, entry "Boniface VI, Pope", New Catholic Encyclopedia^[39]

What Deposition from Orders Meant in the 9th Century

The underlying Latin formula is depositio ab ordine: deposition from the order. It does not simply mean the loss of an administrative function. It implies a juridical act by ecclesiastical authority that withdraws from the cleric the exercise and dignity of his order, whose effects last until a canonical reinstatement is pronounced by a competent authority.

Roman practice in the 9th century provided for:

• an investigation of the facts, sometimes summary;
• a declaration by the bishop or a synod;
• loss of ecclesiastical benefices attached to the order;
• prohibition to publicly exercise the functions linked to the deposited order;
• the necessity, to return to ministry, of an explicit act of reinstatement.

Without this last act, the cleric remains juridically as if he did not have the order concerned. The 898 council only recalls this discipline. It does not create the rule; it applies it to a case that had spectacularly flouted it.

The Powder-Keg Pontificate of Formosus

The pontificate of Formosus (891-896) had been one of the tensest of the 9th century. A former missionary in Bulgaria under Nicholas I, bishop of Porto, then cardinal-bishop under legally contested conditions by his opponents, he had both consolidated the Roman position in the East and created a lasting opposition within the clergy.^[40]

His policy had shifted in favor of the King of Germany Arnulf of Carinthia, against the Spoletan house of Lambert and his mother Ageltrude, whom he had nevertheless crowned before. This double game, judged prudent by Formosus, was perceived as a betrayal by Spoleto.

The Coronation of Arnulf of Carinthia in February 896

In February 896, Arnulf arrived in Rome at the head of an army. He took the city from Ageltrude on February 21, and the next day, Formosus crowned him Roman Emperor in the old St. Peter's Basilica.^[41] The act was solemn; it sealed the open alliance between Rome and the Eastern Carolingians against the house of Spoleto.

Arnulf immediately marched against Spoleto, but on the way he was struck by paralysis and had to interrupt the campaign. The physical collapse of the emperor left the Italian peninsula in a state of unstable equilibrium: Spoleto retained its forces, Rome no longer knew on which protector to rely, and the German garrison was commanded remotely by an Arnulf unable to act.^[42]

The Death of Formosus on April 4, 896

Formosus died on April 4, 896, six weeks after Arnulf’s coronation. His death created a vacuum in Rome at the most dangerous moment possible: the city was still occupied by Carolingian troops, but without their emperor capable of imposing his arbitration; the Spoletan party awaited revenge; and the Roman clergy was divided between Formosians and anti-Formosians, between supporters of loyalty to Arnulf and supporters of reconciliation with Lambert.

Faroldo, the German Governor in Rome

Treccani notes that at the time of Boniface VI’s election, Rome was administered by a German governor named Faroldo, acting on behalf of Arnulf and supported by imperial garrisons.^[43] This German military presence is a major factor in the dossier: it explains why the Spoletan party could not immediately impose itself and why a popular, rapid, and Roman election could take shape outside the usual great clans.

The election of a Roman like Boniface, twice deposed, without a great aristocratic figure behind him, is compatible with a situation of authority vacuum: no party had the strength to impose its own candidate, and popular pressure carried the decision.

Spoleto against Arnulf

This underlying tension would not be resolved in April. It would continue to shape the papacy for years. Stephen VI, elected on May 22, 896, would be explicitly presented as the candidate of the Spoletan faction, and his most infamously remembered act, the Cadaver Synod of January 897, would be a posthumous revenge against Formosus, in favor of Lambert and Ageltrude.^[44]

Boniface VI thus fits into a strategic sequence: Formosus, the Carolingian pope; Boniface VI, the transitional pope elected amid the riot; Stephen VI, the Spoletan pope. The fifteen days of April 896 are a passage, not a reign.

An Election "a furor di popolo"

Treccani highlights, referring to the acts of the Roman council of 898 (constitution III in the numbering it follows), the decisive phrase: Boniface VI was elected a furor di popolo, in the fury of the people, amid a riot.^[45] The term is legal: it describes an irregular election, not preceded by a canonical convocation of the clergy, not framed by a stable procedure, and where the pressure of a crowd replaces the consultation of competent ecclesiastical electors.

According to ancient Roman discipline, the pontifical election required the convocation of the clergy, the agreement of the presbyterium, the advice of neighboring bishops, and the recognition of the people — not the reverse. A popular acclamation could participate in the election; it could not constitute it alone.

Which Faction Elected Boniface?

Sources differ on this point. Encyclopedia.com indicates that the group of Lambert of Spoleto pushed the election, which would correspond to a tactical compromise: to fill the vacant See as quickly as possible before Arnulf regained control.^[46] Treccani avoids this too clear identification and rather presents an election in the void left by Arnulf’s absence, under the mixed pressure of the people and factions not precisely identified.^[47]

A cautious reading is possible: Boniface does not appear in any source as a man of the Spoletan party; but his rapid election probably suited all actors who wanted a pope immediately. A deposed subdeacon, without a powerful clan, had the advantage of calming immediate tensions without committing Rome to a clear political direction.

The Fundamental Canonical Illegality

The irregularity is not only due to the tumultuous mode of election. It is mainly due to the canonical status of the candidate. A man twice canonically deposed, and not reinstated, cannot be validly elected to the bishopric of Rome. This rule is ancient in the Latin tradition and is not an invention of John IX in 898.

The council of 898 therefore articulated two cumulative grievances:

• furor populi: election without regular procedure;
• defectus canonicus: election of a canonically impeded cleric.

It is the combination of the two that made the conciliar decision inevitable.

What Is Known of His Acts?

Nothing, or almost nothing. The Regesta Pontificum Romanorum of Philipp Jaffé, the standard collection of medieval pontifical acts, mentions no letter, no charter, no privilege issued by Boniface VI during his short reign.^[48] The absence is not definitive proof — documents may have been destroyed — but it confirms the general impression: this fifteen-day pontificate left no lasting administrative trace.

This sterility is consistent with the context. The Roman curia was paralyzed. Functions were carried out by routine. And the pope’s health rapidly deteriorated after his election.

The Disease of Gout

The Liber Pontificalis specifies that Boniface died podagrico morbo correptus, struck by the disease of gout.^[49][50] Podagra, in ancient medical vocabulary, refers to an acute form of gout localized in the foot, with possible systemic complications. In the 9th century, without effective treatment, an acute crisis in an already elderly man could cause rapid renal or cardiac decompensation.

Boniface VI’s exact age at the time of his election is unknown: the Liber Pontificalis, silent on his birth, records only the cause of his death, podagrico morbo correptus.^[51] The website Aleteia, in an investigation of the oldest popes at the time of their election (Philip Kosloski, April 25, 2025), states for its part, word-for-word, that he "was elected when he was 90 years old", without citing any primary source in support.^[52]

Natural Death or Violent Elimination?

The dual tradition reported by the Catholic Encyclopedia is famous:

"After a pontificate of fifteen days, he is said by some to have died of the gout, by others to have been forcibly ejected to make way for Stephen VI, the candidate of the Spoletan party." — Thomas Oestreich, Catholic Encyclopedia, vol. 2, 1907^[53]

The Liber Pontificalis mentions only podagra, which leans toward a natural death. Britannica and Encyclopedia.com mention the alternative hypothesis of violent elimination as a secondary polemical reading.^[54]

Modern historiography remains cautious. No documentary evidence supports physical eviction; the date concordance (death on April 26, election of Stephen VI on May 22) even leaves about a month’s interval that does not suggest a succession precipitated by force. The most likely reading is that of the Liber Pontificalis: natural death by acute podagra crisis. The tradition of violent eviction probably reflects the tense political atmosphere of the time, projected onto a more banal event.

Burial at the Portico of the Popes

Boniface VI was buried at the portico of the popes of the old St. Peter’s Basilica in the Vatican.^[55][56] This entrance atrium, located before the nave, had housed a group of pontifical tombs since the 7th century. Burial there was a sign of ecclesiastical recognition: Boniface was interred as a pope, not as a usurper.

This decision is important. If Rome had then considered his election totally null, burial in the pontifical portico would have been problematic. That Boniface was buried there shows that, at that very moment, he was regarded as a real pope, leaving it to a later council to judge the regularity of his election.

The Fragmentary Epitaph

Treccani notes that a fragment of Boniface VI’s epitaph survives in the atrium of the old Vatican basilica: Mallio attests to having read its text, of which only a poorly transmitted fragment remains, restored in emended form by G. B. de Rossi and attributable to Boniface VI, whose tomb stood in the entrance atrium.^[57] The preserved text is too short to provide a spiritual biography, but its mere existence again attests to the official recognition of his pontifical status at the time of his death.

This inscription fragment is one of the very rare direct material traces of the pontificate. Together with the notice in the Liber Pontificalis, it forms the most solid documentary basis for considering Boniface VI without getting lost in later reconstructions.

The election of Stephen VI on May 22, 896

Boniface VI died on April 26, 896, leaving the Roman See vacant for less than a month before the election of Stephen VI on May 22, 896. Wikipedia explicitly notes that the circumstances of his election are unclear, but that he was supported by one of the powerful Roman families, the Dukes of Spoleto.^[58] The political sequence is now reversed: the faction that had been marginalized under Formosus regains control.

Stephen VI would govern from May 896 to August 897, a little over fifteen months.^[59] His pontificate would be marked by the most notoriously infamous act of the saeculum obscurum.

The Cadaver Synod in January 897

The Cadaver Synod took place at the Basilica of St. John Lateran in January 897. Stephen VI had the body of Formosus, who had been dead for about nine months, exhumed. The corpse was dressed in pontifical vestments, placed on a throne, and a deacon was appointed to answer on his behalf during the posthumous trial.^[60][61]

Formosus was accused of three charges: violation of canon law by the transfer of a bishopric, perjury, and exercising episcopal functions as a layman. The tribunal declared him guilty. His papacy was retroactively annulled, and his ordinations invalidated. The body was stripped of its pontifical garments, three fingers of the right hand—the blessing fingers—were cut off, and then the corpse was thrown into the Tiber.^[62]

The fall of Stephen VI in July-August 897

The scandal of the Cadaver Synod provoked an immediate reaction. A Roman revolt broke out. Stephen VI was deposed, imprisoned, and strangled in his prison in July or August 897.^[63][64] The sequence that had begun with Boniface VI ended violently for his successor.

Three brief popes followed: Romanus (August-November 897), Theodore II (November-December 897), then John IX from January 898.

Theodore II and the first rehabilitation of Formosus

Theodore II, pope in December 897 for a reign of about twenty days, held a first synod that annulled the judgment of the Cadaver Synod and had Formosus reburied at St. Peter's.^[65] This initial decision was confirmed and expanded by John IX the following year.

Systematic repair

John IX convened, immediately upon his election in January 898, two successive synods: one in Rome, the other in Ravenna.^[66][67] Their triple objective was to definitively rehabilitate Formosus, condemn the Cadaver Synod, and reorganize electoral rules to prevent a recurrence of what had happened in April 896.

The Roman synod of 898:

• declared the judgment against Formosus null;
• ordered the destruction of all acts of the Cadaver Synod;
• restored to office the clerics deposed by Stephen VI;
• excommunicated seven cardinals who had taken part in the posthumous trial;
• forbade any future trial against a deceased person;
• drew the disciplinary lesson of 896: preventing the return of elections extracted by violence — the Ravenna synod decreed measures against generalized violence, but no precise electoral canon targeting the furores populi is attested in the preserved acts; this is a probable aim, not an established decision.^[68][69]

The annulment of Boniface VI's election

It was in this context that the council pronounced the nullity of Boniface VI's election.^[70][71] The decision was not a mere moral condemnation: it targeted a precise objective canonical defect. Boniface, twice deposed without regular reinstatement, could not have been validly elected pope.

The conciliar act also qualified the election as tumultuous, a furor di popolo according to the formulation reported by Treccani. It thus distinguished two orders of nullity: defect in the person and defect in the procedure. This distinction is legally valuable: it avoids reducing the sentence to an ad hominem attack and grounds it in ecclesiastical discipline.

Why Boniface VI nevertheless remains in the pontifical list

If the council of 898 declared his election null, why does Boniface VI today appear as the 112th pope in the official list of the Holy See?^[72] The answer is both historical and theological.

The Roman Church never sought to erase Boniface VI from the pontifical chronology. It did something more subtle: it maintained the historical fact of his election and burial as pope, while refusing to draw from it a positive recognition of the regularity of his election. This is a distinction between visible chronology and canonical legitimacy that Catholic tradition has often used to handle borderline cases—antipopes, contested elections, ambiguous resignations.

A Doctrinally Neutral Pope, Canonically Irregular

One of the decisive points in the case of Boniface VI is that nothing touches on doctrine. No dogmatic definition, no encyclical, no liturgical decision was promulgated during the fifteen days of April 896. The defect concerns only the mode of election and the person of the elected, never the faith.

This doctrinal neutrality is providential. It allowed the Church to manage the crisis as a disciplinary and chronological matter, without ever having to rule on the value of a magisterial act produced under irregular conditions. The saeculum obscurum could have caused much more damage if one of its fragile pontificates had, for example, promulgated a questionable dogmatic definition.

A Lesson on the Need for Electoral Rules

The Boniface VI case and the entire 896-898 sequence actually accelerated Roman awareness: the pontifical election must be removed from popular pressure, urban factions, and family ambitions. The decrees of 898 go in this direction through their measures against violence and the repair of vitiated elections, without however delivering any precise electoral canon. But it would take two centuries to achieve a true reform: the decree of Pope Nicholas II of 1059 reserving the election to the cardinals, extended by medieval and modern conclaves.

Historical humility consists in recognizing that Rome did not invent the conclave all at once, under direct inspiration; it forged it through trials, failures, scandals, and learning. Boniface VI is part of the lessons.

The Continuity of the Chair of Peter in the Storm

Theologically, the Boniface VI case illustrates a simple and strong thesis. The chair remains even when its temporary occupant is unworthy, because it does not depend on the human regularity of the electoral procedure nor on the holiness of the elected. It rests on an explicit promise of Christ to Peter, transmitted by the Gospel according to Saint Matthew.

“You are Peter, and on this rock I will build my Church, and the gates of hell shall not prevail against it.” — Gospel according to Saint Matthew, 16:18^[73]

This doctrine is constantly affirmed by Catholic tradition: the Petrine promise is attached to the seat, the office, the succession, not to the individual holiness of each holder. Saint Augustine had already recalled this against the Donatists regarding the sacraments: the validity of the act does not depend on the holiness of the minister. The papacy is not a merit; it is a entrusted service.

“Where Peter is, there is the Church; and where the Church is, there is no death, but eternal life.” — Saint Ambrose of Milan, Commentary on Psalm 40^[74]

This statement, which will be taken up by the entire Latin tradition on Roman primacy, does not mean that every pope lives this service in holiness. It means that the chair of Peter is, by divine institution, the visible place of Catholic unity, whatever the miseries of its occupants.

“Does Boniface VI prove that the papacy is only a political matter?”

No. He proves that the papacy is, like any human institution inscribed in history, exposed to political conflicts. The difference is significant. A purely political matter would have left neither the chair nor the memory; a divine institution inscribed in history absorbs crises without disappearing.

The saeculum obscurum is precisely the hardest test of this resilience. The papacy emerges weakened but continues. It does not disappear, it does not disintegrate, and a century later, under the Gregorian reformers, it will resume strict electoral and moral discipline. The counter-test would be a simply political institution: none has survived such trials while maintaining its structure.

“If his election was null, how does he remain on the list?”

Because the Catholic Church distinguishes, in its treatment of borderline cases, the legal effect of a conciliar decision and the visible chronology of apostolic succession. The 898 council declared the election null; it did not demand erasing Boniface VI from the pontifical chronologies nor erasing his burial at the portico of the popes.

The Holy See, by maintaining Boniface VI in the official list, does not say he is an exemplary pope. It says he is a historical fact of the chair of Peter. It is the same prudence that maintains the memory of less glorious popes of the 9th and 10th centuries, without presenting them as models.

“Baronius called him a ‘monstrum’: should we keep this harshness?”

The great annalist Cesare Baronio (1538-1607) indeed called Boniface VI a monstrum (disgusting monster) and accused him of adultery and homicide.^[75] These accusations are taken from the post-Tridentine polemical tradition and have no direct primary source to support the specific charges.

Historical prudence consists in retaining the certain fact — the two depositions for unworthy conduct — and not overloading the details. Primary sources speak of immorality in a broad sense, not homicide. Reintroducing these accusations without sourcing would cause the Catholic article to lose its rigor without spiritual gain: the sentence of the 898 council is more than sufficient to justify the canonical condemnation.

“Does the 898 council render his penance vain?”

This question is more delicate. The council rules on the legal regularity of the election, not on the eternal salvation of Boniface VI. It says his election was canonically null; it does not say the man is damned. A sinner reinstated, or not canonically reinstated, can always die reconciled with God in the secret of his heart.

Catholic tradition leaves the judgment of the internal forum to divine mercy. The historian has no element on Boniface VI’s dispositions at the moment of his death. The fragmentary epitaph preserved at Saint Peter’s, as well as the burial at the pontifical portico, testify at least that Rome did not consider him irretrievably lost.

• Pope Formosus — immediate predecessor, whose death on April 4, 896 opens the Roman crisis in which Boniface VI is elected.
• Pope Stephen VI — successor; pope of the Cadaver Synod, candidate of the Spoletan party.
• Pope John IX — pope who rehabilitated Formosus and annulled Boniface VI’s election at the Roman council of 898.
• Cadaver Synod — posthumous trial of Formosus in January 897; a dramatic turning point of the papacy during the saeculum obscurum.
• Saeculum obscurum — the darkest period of the medieval papacy, of which April 896 is one of the thresholds.
• Pope Saint Boniface IV — for comparing a strong Carolingian pontificate with a collapsed Roman pontificate.
• Pope Nicholas II — for the Gregorian reform of papal electoral law in 1059, which partly resolved the problems opened in 896.
• Old St. Peter’s Basilica — to locate the papal portico where Boniface VI was buried.
