The Incorrupt Bodies

The bodies of the martyrs and primitive veneration

Christianity did not invent the veneration of holy bodies: it transformed it by investing it with a new meaning. For the early Christians, the martyr's body is more than mortal remains — it is the temple of the Holy Spirit (1 Cor 6:19–20), destined for the resurrection. Devotion to the bodies of the martyrs goes hand in hand with paschal faith.

As early as the 2nd century, accounts mention the bodies of martyrs found in a remarkable state after their execution. The Martyrdom of Saint Polycarp (c. AD 156), one of the oldest Christian martyrdom accounts, describes the faithful of Smyrna carefully gathering the bones of the old bishop to preserve them as "precious stones more precious than refined gold".^[3] The emphasis falls on the dignity of the martyr's body, even though no extraordinary incorruption is claimed in this particular case.

"We afterwards collected his bones, more precious than costly stones and more esteemed than gold, and laid them in a suitable place. There the Lord will permit us, so far as possible, to gather together in joy and gladness, to celebrate the anniversary of his martyrdom." — Martyrdom of Saint Polycarp, ch. XVIII, c. AD 156^[4]

Saint Augustine devoted an entire treatise to the question of the honour due to the bodies of the saints, De Cura pro Mortuis Gerenda (c. AD 421). In it he defends the legitimacy of Christian burial as a sign of the coming resurrection, without confusing the mortal body with the glorified body yet to come. His most frequently cited passage on this point — rendered here in paraphrase, the exact Latin text being given in a note — comes down to a single sentence:

"The bodies of the departed — especially those of the just and the faithful, which the Spirit used as organs and instruments for every good work — must be neither despised nor abandoned." (paraphrase) — Saint Augustine, De Cura pro Mortuis Gerenda, ch. V, c. 421^[5]

The first documented signs in medieval hagiography

The Middle Ages multiplied testimonies of exhumations revealing preserved bodies. The Golden Legend of Jacobus de Voragine (c. 1260) abounds in them, although one must distinguish edifying hagiographic accounts from official records of canonical exhumations. Only from the 13th century onward did canonisation procedures become formalised, and exhumations begin to be the subject of written reports by physicians and identified witnesses.

One of the earliest medieval cases to be rigorously documented is that of Saint Gregory VII (d. 1085), whose relics were examined when his tomb was reopened. But it is especially from the 13th century onward that the cases multiply with more serious documentation, linked to the development of the canonical procedure of beatification under Popes Innocent III and Gregory IX.

An early and spectacular case is that of the tongue of Saint Anthony of Padua (1195–1231), found intact at the translation of his relics in 1263, thirty-two years after his death — a case detailed below in the dossier of the major cases examined.^[6]

The Fundamental Canonical Distinction: Benedict XIV

The most rigorous canonical reflection on this subject is due to Cardinal Prospero Lambertini, the future Pope Benedict XIV. In his monumental treatise De Servorum Dei Beatificatione et Beatorum Canonizatione (1734–1747, 4 volumes), he devotes substantial discussions to the question of bodily incorruption in the context of beatification and canonization proceedings.^[7]

His position is remarkably clear-sighted: the incorruption of the body is not in itself a miracle, and therefore cannot serve as canonical proof of holiness. Several reasons lead him to this conclusion: bodies may be preserved by natural causes (embalming, soil, atmospheric conditions), some sinners may have well-preserved bodies, and some eminent saints have had bodies quickly reduced to dust.

"The incorruption of the body, such as may be found in a servant of God, cannot be admitted as a miracle unless the natural causes capable of producing this effect have first been excluded by certain proofs." — Benedict XIV (Prospero Lambertini), De Servorum Dei Beatificatione, lib. IV, pars 1, cap. XXXIII, Rome, 1747^[8]

This position of prudence is fundamental: it means that the Church is not naive on this subject, and that its attachment to the most impressive cases is not credulity.

The Six Associated Signs, in the Line of Herbert Thurston

The Jesuit father Herbert Thurston devoted several chapters of his study The Physical Phenomena of Mysticism (1952) to incorruptible bodies — "Incorruption," "The Absence of Cadaveric Rigidity," "Blood Prodigies" — without drawing up a closed list.^[9] The synthesis below groups into six traits the signs that recur most often in the cases he studies and in later literature (Cruz, Bouflet); they are not always found together:

1. Absence of putrefaction — no fetid odor, no visible progressive decomposition
2. Sweet fragrance — a smell of flowers or indefinable scents, distinct from that of an embalmed body (the "odor of sanctity," to which Thurston also devotes a chapter)
3. Post-mortem suppleness — absence of cadaveric rigidity and flexibility of the joints observed at exhumation, sometimes years after death
4. Warmth of the body — in the hours following death, some bodies remain warm longer than usual
5. Unexplained exudations — blood, oil, or liquid flowing from the body ("blood prodigies," another chapter of Thurston; see the Charbel file below)
6. Preservation in a hostile environment — bodies intact despite quicklime, water, or the dampness of the tomb (see Xavier on Sancian, Hardini in his flooded vault)

What matters is that these signs, when they accumulate and persist over time, resist the usual explanations of natural preservation.

What Must Be Distinguished from Catholic Incorruption

The term "incorruptible" is commonly used to designate any well-preserved body. At least four very different situations must be distinguished:

The distinction between these categories is the first task of honest expertise.

What Bouflet calls the "punctual miracle"

The historian of mystical phenomena Joachim Bouflet, in the chapter that his Encyclopédie des phénomènes extraordinaires dans la vie mystique devotes specifically to "The incorruption of the body," offers the most useful conceptual distinction for reading this dossier correctly. He begins by recalling the exact thanatological definition of the two main false positives:

"Saponification is the transformation of a fatty body into soap. In thanatology, the term refers to the formation of a whitish substance, a kind of ammoniacal soap called adipocire [...] which results from chemical reactions in the organic tissues, when the deceased's body is subjected to particular conditions: drowning, the piling up of several corpses." — Joachim Bouflet, Encyclopédie des phénomènes extraordinaires dans la vie mystique, vol. 1, Le Jardin des Livres, updated edition, 2018 printing, p. 388^[10]

"No more than saponification is mummification held by the Church to be a miracle of incorruption." — Joachim Bouflet, op. cit., p. 389^[11]

From this Bouflet draws a decisive thesis, built on the tracking over nearly four centuries of the body of the Spanish Carmelite Catherine of Christ (d. 1594). What must be established is not necessarily the present state of a body — which has sometimes become a natural mummy, sometimes even been reduced to a skeleton decades later — but the initial absence of putrefaction during a period when it would normally have occurred:

"The miracle consisted in the fact that it did not suffer corruption in the first days, months and years after death. What now remains dry, cardboard-like, blackened, etc., serves as incontrovertible testimony to the fact that the corpse underwent no corruption." — Father Oscar González-Quevedo, report of 27 October 1981, cited by Bouflet, op. cit., p. 423^[12]

"Incorruption is not a 'continued miracle,' but a punctual prodigy that has the value of a sign and in which the Church sometimes recognizes an authentic miracle." — Joachim Bouflet, op. cit., p. 424^[13]

This distinction entirely changes the way a dossier such as that of Charbel Makhlouf, presented below, is read: a body today reduced to a skeleton may very well have presented a genuinely extraordinary phenomenon in the months following death — the one does not erase the other. Conversely, it forbids writing that an "incorruptible" body necessarily remains intact forever.

The body can become corruptible again: two cases that attest to this

The dossier of the Italian religious Maria Domenica Brun Barbantini (1789–1868) and Maria Gabriella Sagheddu (1914–1939) concretely illustrates the sometimes temporary nature of the phenomenon.

At the recognition of 1928, sixty years after the death of Maria Domenica Brun Barbantini, the witnesses observe a whole body bathed in the water of the coffin:

"I saw the corpse whole, the mouth half open, the chin resting on the chest, with a great deal of water in the coffin." — Minutes of the 1928 recognition, cited by Bouflet, op. cit., p. 412^[14]

But at a further recognition, on 3 July 1979, more than fifty years later, the finding is radically different:

"The body was in an advanced state of decomposition, the bones intact, however, and almost complete in number." — Minutes of 3 July 1979, cited by Bouflet, op. cit., p. 412^[15]

Likewise, Maria Gabriella Sagheddu, a Trappist nun who died in 1939 at the age of twenty-five, is found intact and supple in 1957; but at a later recognition in 1975, only the hands and forearms still show mummification, the rest of the body having resumed its ordinary course of decay.^[16] These two dossiers impose a simple methodological conclusion: a genuinely unexplained phenomenon of preservation at a given date guarantees nothing about the state of the body at subsequent dates, and the absence of definitive preservation does not retroactively restore the natural explanations ruled out at the time of the initial finding.

Saint Bernadette Soubirous (1844–1879) — the most rigorous dossier

Saint Bernadette Soubirous, the visionary of Lourdes (1858), withdrew to the Saint-Gildard convent of the Sisters of Charity in Nevers, where she died on 16 April 1879 at the age of 35, of pulmonary tuberculosis. She is still preserved there.

Her dossier is one of the best documented, thanks to the three canonical recognitions of the body carried out in succession in the framework of the cause of beatification and canonization:

What the case of Bernadette teaches: incorruption does not necessarily mean that the body is identical to that of a living person. It means that ordinary decomposition has been considerably slowed or altered, without sufficient natural explanation in the light of the context. The partial mummification observed in 1919 is itself out of the ordinary for a body buried thirty-five years in a damp tomb in the Nevers region. It must be said clearly, however: the Church has never pronounced on the miraculous character of this preservation.^[20] Bernadette Soubirous was canonized on the dossier of the apparitions of Lourdes and her heroic virtues, not on the state of her body.

Saint Francis Xavier (1506–1552) — the missionary of Goa

Saint Francis Xavier, apostle of the Indies and Japan, died on 3 December 1552 on the island of Shangchuan (Sancian), off the coast of China, abandoned on the beach with two companions. He was 46 years old. His body was temporarily buried in quicklime to decompose the flesh and facilitate the transport of the bones to Goa.

When the tomb was reopened two months later, his companions found the body perfectly intact, the quicklime having produced no effect — which Xavier's contemporary biographers noted as the first remarkable sign.^[21] The body was exhumed, taken to Malacca, then to Goa, where it arrived in March 1554. Successive examinations documented a state of preservation beyond explanation.

The body is today kept in the Basilica of Bom Jesus in Old Goa, in a glass reliquary since 1637. Decennial expositions (every ten years since 1782) allow the veneration of the body, drawing millions of pilgrims. The most recent, the XVIII exposition (21 November 2024 – 5 January 2025), drew more than 7 million pilgrims.^[22]

Saint Catherine of Siena (1347-1380) — seven centuries partly preserved

Saint Catherine of Siena, a mantellata of the Dominican Third Order, a political mystic of the medieval Church and Doctor of the Church (proclaimed by Paul VI in 1970), died in Rome on 29 April 1380, at 33, after months of immobility offered for the reform of the Church and the return of the papacy to Rome. Her body was first displayed in the basilica of Santa Maria sopra Minerva, where an enormous crowd pressed to venerate her for three days.

Her confessor and biographer Raymond of Capua, who wrote her official biography (Legenda Maior, completed around 1395), reports that Catherine's body remained free of any signs of corruption during the three days of public exposition in Rome — a notable fact for a woman who had died of extreme exhaustion in April, under conditions ordinarily unfavourable to preservation. It was on this early observation, passed on by the first Dominicans of the Sienese sequela, that the first veneration of her relics was built.^[23]

Her head was separated from the body and transferred to Siena as early as 1384 at the request of the Dominicans of her native city, where it is kept — in a domed gilded reliquary — in the Basilica of Saint Dominic in Siena. The rest of the body remained in Rome, beneath the high altar of Santa Maria sopra Minerva. One hundred and seventy-two years after her death, in 1552, an official inspection of the body documented a striking state of preservation, with the persistence of the sweet fragrance noted by the first witnesses.^[24]

Today, her body still rests beneath the high altar of Santa Maria sopra Minerva in Rome, in a marble and glass reliquary, venerated for seven centuries by pilgrims. Her right thumb — the one which, according to Raymond of Capua, bore the invisible sign of the side stigmata of Christ — and a fragment of the arm are kept respectively in the reliquary of the Dominican convent in Rome and in the basilica of Siena.^[25]

Saint John Vianney (1786-1859) — the Curé of Ars

Saint John Vianney, curé of Ars for 41 years (1818-1859), died on 4 August 1859 at 73, exhausted by a life of radical mortification, extreme fasting and unceasing intercession. In the last years of his ministry, he spent up to sixteen to eighteen hours a day in the confessional, receiving each year tens of thousands of penitents who came from all over France and Europe for the "grace of the Curé of Ars".^[26]

His body was exhumed on 17 June 1904, nearly forty-five years after his death, at the opening of the apostolic process of beatification desired by Pius X. The Bishop of Belley, the appointed doctors and the canons of the cause found a whole body, recognisable, whose skin had remained in place over the bones, without the signs of putrefaction expected for remains buried so long in the soil of the parish cemetery.^[27] To prepare for the exposition to the faithful, a fine wax mask was applied to the face and hands — not because the face was disfigured, but in keeping with the usual practice of shrines displaying a body in a glass reliquary, in order to protect the features from the wear of decades of exposure. Bouflet himself places this case in the category of natural mummification and concludes that there is "probably nothing miraculous" about it.^[28]

Pius X beatified him on 8 January 1905 and Pius XI canonised him on 31 May 1925, the same year as Thérèse of Lisieux. Pius XI then proclaimed him principal patron of all the parish priests of the world in 1929. His reliquary, transferred beneath the vault of the basilica in 1925, still draws some 550,000 pilgrims a year to the shrine of Ars-sur-Formans, making this modest parish of the Ain one of the greatest centres of priestly pilgrimage in the world.^[29]

Saint Catherine Labouré (1806-1876) — rue du Bac, Paris

Saint Catherine Labouré, a Daughter of Charity, received in 1830 the apparitions of the Virgin Mary at the chapel on the rue du Bac in Paris, leading to the creation of the Miraculous Medal. She died on 31 December 1876 at 70.

57 years after her death, at the official exhumation for her cause of beatification in 1933, her body was found in a state of preservation judged remarkable. The wood of the coffin had completely rotted in the dampness of the crypt, but the remains were whole, and the suppleness of the joints struck the appointed doctors.

"The body is in a perfect state of preservation, and its joints are still supple." — Report of the exhumation of Catherine Labouré, archives of the Daughters of Charity, Paris, 1933^[30]

Her incorrupt body is today exposed in a glass coffin beneath the side altar of the Chapel of the Miraculous Medal, 140 rue du Bac, Paris (7th arrondissement), where thousands of pilgrims venerate it each year. Catherine Labouré was beatified by Pius XI in 1933 and canonised by Pius XII in 1947.^[31] Not all the descriptions are the same, however: Dr Didier, present at the exhumation, spoke for his part of "slight mummification", with parchment-like skin and desiccated viscera.^[32] The two findings do not contradict each other: they describe, from different angles, a body better preserved than the context would have led one to expect, without the Church ever having seen in it a formal miracle.

Saint Charbel Makhlouf (1828-1898) — the most disputed case, and the best documented

The case of Saint Charbel Makhlouf, a Lebanese Maronite monk, is at once the most famous and the most badly summarised of the cases of incorruption. He died on 24 December 1898 at the monastery of Saint Maron in Annaya (Lebanon), after forty-seven years of monastic life and sixteen years of hermitage, and was buried the following day in the common cemetery of the monastery, where thirty-two other religious already lay, whose remains were normally decomposed.^[33] The ground, saturated with water by the infiltrations of a defective roof, was particularly unfavourable to any preservation.

Lights over the grave, then an exhumation. A few weeks after the burial, some religious reported unexplained lights surrounding the grave at night, observed on several occasions over approximately forty-five nights. Brother Élie Mehrini, the witness Miladé Chehadé, and even the Muslim prefect of the region, Mahmoud Hémadé, attested to the phenomenon; it was the repetition of these lights that led the superiors to order the exhumation.^[34] An informal inspection took place on 9 February 1899, followed by a more official one about three months after the funeral:

« The hermit's body was found intact, supple and flexible as if he were alive, covered with a light layer of white mould, while the handle of the shovel, forgotten in the grave on the day of the burial, was damaged. » — Patrizia Cattaneo, Les secrets du corps intact de saint Charbel, 2ᵉ éd., Éditions du Parvis, Hauteville, janvier 2025, p. 27^[35]

The common grave, however, contained elements that contradict a too-smooth image: the deceased's tunic, described as "entirely covered with worms", and a face damaged by water seepage that had "partially detached his beard, pierced his nose and lips and damaged his right eye".^[36] These unfavourable details, recorded by the witnesses themselves, are what make the file credible: no one doctored the scene to produce an edifying account.

A parallel case at the same monastery. The same type of luminous phenomenon was reported over the grave of Saint Rafqa Ar-Rayès (1832–1914), a nun of the same Lebanese Maronite Order of Saint Anthony, whose cause was accepted in Rome the same year as Charbel's — a testimony attested by Dorgham Al-Koury Khaïrallah.^[37] This doubling of the phenomenon, in the same monastic setting and across an interval of several decades, rules out the hypothesis of an isolated fact peculiar to Charbel alone. See the article dedicated to Saint Rafqa Ar-Rayès.

Human interventions that must be counted, not hidden. Far from leaving the body intact, the monastery authorities multiplied their interventions over the following years: night-time exposure to dry air for several months in 1899, cleaning with alcohol, then the placing of quicklime beneath the feet of the body in 1908 — with no effect on the exudation, which continued "abundantly" despite these attempts to dry it out.^[38] A twenty-centimetre incision was then made in the side to remove the viscera: stomach, intestines, heart, lungs, liver and gallbladder, found "intact, with no worms or signs of decomposition".^[39] This evisceration is a fact to be honestly incorporated into the file — but it took place after the first findings of preservation, and therefore cannot account for the initial weeks.

Dr Choukrallah's follow-up. The physician Georges Choukrallah examined the body on thirty-four occasions between 1909 and 1926 — an exceptional longitudinal follow-up for the period. His report of 16 October 1926 gives precise measurements:

« The body [...] measures 149 centimetres from the shoulder to the soles of the feet. [...] The skin is largely dried out, but supple on the hands and back. [...] the joints remain flexible and bendable [...]. » — Dr Georges Choukrallah, report of 16 October 1926, cited by Cattaneo, op. cit., p. 44-45^[40]

Choukrallah identified the exuded liquid as blood plasma — a visual identification reaffirmed on several occasions, but one that no biochemical analysis documented in the available sources supports.^[41]

The 1927 expertise: the naturalistic counter-file, to be laid out without evasion. On the orders of the diocesan commission, professors Armand Geoffroy and Balthazar Melconian, of the French Faculty of Medicine in Beirut, examined the body on 30 July 1927. Their conclusions do not describe a fresh, odourless body, but a corpse in the process of breaking down:

« Clothed body: a strong odour, familiar to anyone who has frequented anatomy rooms, autopsy theatres and laboratories, emanates from the corpse — a spiced, acidic smell, that of cadaverisation with adipocere degeneration. » — Armand Geoffroy and Balthazar Melconian, medical expert report, 30 July 1927, cited by Cattaneo, op. cit., p. 102^[42]

« The corpse is currently undergoing decomposition, which explains its odour and the elimination of fatty bodies from its surface. » — Geoffroy and Melconian, op. cit., p. 107^[43]

The two experts put forward a partial explanation, combining the evisceration of 1899 and a desiccation effect:

« First completely eviscerated, which explains the delay in putrefaction. That the external teguments [...] have manifestly been preserved by a form of smoking to be specified — summary but nevertheless sufficient to bring about apparent mummification. That the underlying tissues, however, have continued their slow decomposition [...] in the direction of adipocere degeneration. » — Geoffroy and Melconian, op. cit., p. 106-107^[44]

This explanation accounts, at least in part, for the state of the body after 1899 — but it leaves open the question of the initial weeks, prior to any intervention, when the body was found intact and supple in a waterlogged cemetery.

The 1950 report: precise exclusions, no satisfactory explanation. After the body had been reburied in a wooden coffin covered with zinc, a commission composed of Joseph Hitti, Chucri Bellan, Théophile Maroun and Simon Guerguerian reopened the niche on 22 April 1950, returned on 4 August, and signed its report on 14 September 1950. The histological examination established that the tissues were in no way alive:

« The tissue fragments submitted for examination revealed a tissue configuration analogous to the normal one, but the cell nuclei are entirely lysed, the protoplasms autolysed, the structural appearance nevertheless remaining preserved. » — Joseph Hitti, Chucri Bellan, Théophile Maroun, Simon Guerguerian, expert report, 14 September 1950, cited by Cattaneo, op. cit., p. 116^[45]

A series of chemical tests methodically excluded the known preservation processes:

« Tests for Tannin [...] Arsenic [...] Mercury [...] Formaldehyde [...] Lead [...] Copper [...] Zinc. All detection reactions remained negative. » — Hitti et al., op. cit., p. 117^[46]

The return on 4 August, in the driest month of the year, confirmed the persistence of localised moisture on the body and the coffin, distinct from the general environment of the crypt:

« This finding confirmed the first and definitively established for us the existence of a production or condensation of water on the corpse and the coffin. » — Hitti et al., op. cit., p. 120^[47]

The commission concluded with remarkable prudence — without triumphalism, without hasty conclusions:

« After the investigations carried out, we cannot put forward a sufficiently convincing and satisfactory explanation of this phenomenon, nor of that of mummification in a humid environment. For the time being we confine ourselves to the findings. » — Hitti et al., op. cit., p. 121^[48]

The later evolution: the body did not remain intact. This is where the article must correct a widespread simplification. According to Bouflet, the decomposition process began in 1957, with reburial; in 1977, at the canonical recognition preceding the canonisation, the body was reduced to a skeleton.^[49] A testimony gathered in February 1977 by Mgr Joseph Mahfouz confirms this evolution:

« His grave has recently been reopened [...] The skin adhered to the skeleton, retaining a certain freshness as well as a reddish tinge (similar to that of wine). » — Testimony of Mgr Joseph Mahfouz, February 1977, cited by Cattaneo, op. cit., p. 87^[50]

The present state, described by Father Hanna Skandar, guardian of the monastery, confirms that one must no longer speak of a body that has remained supple to this day:

« Today, the body of Saint Charbel is reduced to a skeleton, covered with skin. [...] After the beatification, it ceased to sweat and lost its flexibility [...]. » — Father Hanna Skandar, interview reported by Cattaneo, op. cit., p. 88^[51]

Figures not to be taken as established facts. Several spectacular estimates have circulated around this case — up to fifty thousand litres of exuded fluid over twenty-eight years, or blood that supposedly remained "biologically alive" in a phial kept since 1950. These figures rest on extrapolations based on an assumed constant daily flow, not on a published and verified series of weighings or analyses; Father Skandar himself states that he did not publish his calculations.^[52] The 1950 report, the only medico-legal document available on the composition of the tissues, records on the contrary the lysis of the nuclei and the autolysis of the protoplasm — the exact opposite of living tissue. These figures therefore do not enter into the evidentiary record of this article.

What the Charbel file establishes, once stripped of its amplifications, amounts to a single sentence: a body buried in the worst possible preservation conditions displayed, before any human intervention, a state unexplained by successive practitioners — the 1927 naturalistic expertise included, which explains part of the phenomenon without exhausting either its origin or its persistence up to 1950. Charbel was beatified by Paul VI on 5 December 1965 and canonised by the same pope on 9 October 1977. The full details of his life and canonisation are the subject of the article dedicated to Saint Charbel Makhlouf.

Four cases with medical follow-up and named witnesses

Beyond the most famous cases, several files assembled by Bouflet stand out for the precision of their sources: identified doctors, exact dates, official commissions. Their evidentiary value lies precisely in this traceability.

Saint Ni'matullah Kassab Al-Hardini (1808-1858), moral theology teacher of the young Charbel Makhlouf at Kfifane, was seen intact by Father Mansour Awad in 1898, 1914, 1923 and 1924, then examined on 6 June 1927:

« Puis le 6 juin 1927, j'ai assisté à l'examen du corps effectué, sur ordre de la commission informative, par le docteur-médecin Jacques-Henri Nabr, professeur à la Faculté Française de Médecine à Beyrouth, assisté par le docteur-médecin Balthazar Malconien ; j'y étais présent en tant que Promoteur de la foi en la Commission. » — Father Mansour Awad, cited by Bouflet, op. cit., p. 401, citing Joseph Mahfouz, Le Serviteur de Dieu le Père Ni'matullah Kassab Al-Hardiny, Postulation, Rome, 1980, p. 68-69^[53]

The body, found in a vault filled with water, was described as "intact and dry" at each of the four visits spread over twenty-six years.^[54] The full account of his life and canonisation is covered in the article dedicated to Saint Ni'matullah Al-Hardini.

Maria Anna Sala (1829-1891), a Marcelline sister, offers one of the best internal controls in the corpus: on 29 January 1920, in the same vault, two fellow sisters who had died at close dates — Teresa De Ry and Francesca Morandi — were found reduced to skeletons, whereas the body of Maria Anna Sala presented a still recognisable face:

« Les premières tombes ouvertes furent celles des défuntes sœurs De Ry Teresa et Morandi Francesca. Nous trouvâmes les restes bien rangés, mais réduits à l'état de squelettes couverts de l'habit religieux. » — Sister Felicità Ballerini, deposition cited by Bouflet, op. cit., p. 409^[55]

« Lorsque le cercueil eut été ouvert à la hauteur de la tête, nous vîmes le linceul [...] blanc comme neige [...] ; le visage de la défunte [était] de couleur rosée [...] et les paupières doucement closes, comme si elle dormait. » — Deposition cited by Bouflet, op. cit., p. 410^[56]

This internal control — three bodies in the same vault, the same environment, close dates of death, two skeletons and one preserved face — is methodologically stronger than an isolated case, since it neutralises the objection of favourable tomb conditions: the conditions were, by definition, identical for the three deceased.

Catherine of Christ (died 1594), a Spanish Carmelite, provides the longest medico-legal follow-up in the corpus, spanning nearly four centuries. In March 1597, three years after her death, three doctors and three surgeons examined a body that had been neither eviscerated nor embalmed:

« On doit savoir qu'on ne lui a enlevé aucune partie de son corps ; elle a encore maintenant les entrailles, le foie, les poumons, le cerveau, sans qu'il y manque rien [...] Ses articulations sont telles qu'on peut lui mouvoir les bras, la tête et les jambes. » — Dr Jerónimo Juan Ruig, legal information of 19 March 1597, cited by Bouflet, op. cit., p. 419^[57]

Nearly four centuries later, in 1981, a new examination methodically excluded the available natural explanations — this is the quotation already used above to establish the notion of a punctual miracle:

« Je n'y ai pas trouvé le moindre vestige de momification artificielle. Cela n'a aucun rapport avec la saponification. Il n'y a non plus aucune ressemblance avec la momification, comme par exemple par l'absence totale d'air, par l'effet de la chaleur et de la sécheresse ambiante. » — Father Oscar González-Quevedo, report of 27 October 1981, cited by Bouflet, op. cit., p. 423^[58]

Cesare Sportelli (1685-1750), a Redemptorist, was examined by a canonical and medical commission established by the Bishop of Nocera in November 1753, after several exhumations rendered necessary by the unwholesomeness of his first burial:

« Le cercueil ayant été ouvert, on trouva de nouveau les vêtements usés et pourris, mais le corps était entier et flexible, aussi beau que celui d'une personne vivante, sans la moindre mauvaise odeur, mais au contraire parfumé. [...] Les viscères étaient également incorrompus et le ventre conservait encore toute son élasticité. » — Compendio della vita del Servo di Dio Padre D. Cesare Sportelli, Avellino, 1895, p. 124, cited by Bouflet, op. cit., p. 431^[59]

The tongue of Saint Anthony of Padua (1195-1231)

Thirty-two years after Anthony's death, in 1263, during the transfer of his relics to the basilica of Padua, the Franciscan friars opened the tomb and found the saint's bones. But part of the soft tissue was preserved: his tongue was entirely intact — fresh, red, supple.^[60] The tongue is precisely the organ that decomposes among the first. Its state of preservation, after thirty-two years in a damp environment, remained unexplained.

Saint Bonaventure, present at the exhumation, took the tongue in his hands and spoke:

« Ô langue bénie, qui as toujours loué le Seigneur et aidé les autres à le louer ! Il apparaît maintenant que tu as obtenu une grande récompense auprès de Dieu. » — Saint Bonaventure, reported by the Franciscan chronicles, 1263^[61]

The tongue of Saint Anthony has been kept ever since in its gilded silver reliquary at the Basilica of Saint Anthony of Padua, exposed to the veneration of the faithful.

Saint Teresa of Ávila (1515-1582) and the testimony of Thérèse of Lisieux

Saint Teresa of Ávila, Doctor of the Church and foundress of the Discalced Carmelites, died on 4 October 1582 at Alba de Tormes (Spain). Her body was exhumed for the first time on 25 November 1585, three years after her death, revealing a remarkable state of preservation and a sweet fragrance.^[62]

In August 2024, on the occasion of a third official inspection, the postulator general of the Order of Discalced Carmelites, Father Marco Chiesa, confirmed that the body was in the same state of preservation as at the previous inspection of 1914 — that is, 440 years after her death.^[63]

The anecdote should be set alongside a human and spiritually illuminating episode. At the Carmel of Lisieux, shortly before her death in 1897, Saint Thérèse of Lisieux heard a novice suggest: "We will find your body incorrupt." She replied spontaneously:

"Oh no! Not that miracle! That would be contrary to my little way of humility." — Saint Thérèse of Lisieux, remarks collected by the Carmelites of Lisieux, 1897^[64]

Yet, upon the first exhumation of her remains on 6 September 1910, the sisters were surprised by the state of preservation of the body, far better than what they had expected after thirteen years.

This anecdote illustrates an essential principle: incorruptibility is neither the goal nor the measure of holiness. It cannot be willed or sought. When it occurs, it imposes itself upon the person concerned regardless — which, for some theologians, is precisely one of the signs of its supernatural origin.

The following table summarizes the available data on the best-documented cases, according to the criteria of preservation, duration, and state at the last inspection:

A second table, this time focusing on cases where science has identified a precise natural explanation, complements the methodological reading of the dossier:

This second table is not a retraction of the first: it illustrates, on the contrary, the method this dossier claims to follow — accepting the natural explanation wherever it applies, so as to give all the more weight to the cases where it does not suffice.

It would be apologetically irresponsible not to examine the scientific objections. They are real, documented, and Catholic honesty consists in taking them seriously before drawing any supernatural conclusion.

Adipocere: Corpse Wax

Adipocere (from the Latin adeps, fat, and cera, wax) is a well-documented phenomenon in forensic medicine. In the presence of moisture and an anaerobic environment (low in oxygen), the fats of the corpse undergo saponification — a transformation into saturated fatty acids forming a solid substance, white or greyish, of a soapy nature. This process can preserve bodies for centuries in a solid state, odorless or with a mild scent.^[66]

Adipocere is a potential explanation for several bodies showing preservation in a damp environment. It does not, however, reproduce cases of prolonged joint flexibility, nor cases of bodies preserved in lead coffins or in dry surroundings.

The Catholic Church itself documents cases of apparent incorruption ultimately attributed to this mechanism. Thirty-five years after the death of Saint Marie-Euphrasie Pelletier (1796-1868), foundress of the Good Shepherd, Dr Thibault explicitly attributed the observed preservation to the hermetic coffin and to water seeping into the vault:

"The skin, with a mummified appearance, hard to the touch, sounding when struck with a metal instrument, covers a substance spread over the entire body. This substance is vulgarly called corpse fat; it covers the bones." — Dr Thibault, deposition cited by Bouflet, Encyclopédie..., vol. 1, Le Jardin des Livres, 2018 printing, p. 389^[67]

"In hermetically sealed coffins, decomposition can be halted: this appears to me to have occurred in the present case." — Dr Thibault, cited by Bouflet, op. cit., p. 390^[68]

Likewise, the examination of the body of the Benedictine Itala Mela (1904-1957) concluded unambiguously to a natural process:

"Judging by the appearance of the body, its state of preservation may be defined as 'in the phase of saponification'." — Itala Mela, Nel dialogo delle Tre Persone, notebook 15, La Spezia, 1984, p. 5, cited by Bouflet, op. cit., p. 450^[69]

These two dossiers, concerning nuns today canonized or under consideration for beatification, show that the Church does not conceal natural explanations when they apply — and that natural preservation in no way tarnishes the recognition of holiness otherwise.

Natural Mummification

In a dry, hot and ventilated environment (or conversely a very cold one), rapid dehydration can mummify a body and preserve it for centuries. Egyptian, Peruvian or Alpine mummies are the classic example. Several bodies presented as "incorruptible" in arid regions or at high altitude may be the result of this process.

Undeclared or Indirect Embalming

Some historians and forensic physicians hold that certain "incorruptibles" in fact benefited from partial or indirect embalming not mentioned in the sources: introduction of balsamic substances at the time of coffining, hermetic lead coffin protecting from oxygen, resins used in shrouds. These practices were common in certain periods and ecclesiastical circles.

The most clearly established case is that of Cardinal Alfredo Ildefonso Schuster (1880-1954), Archbishop of Milan, whose remarkable preservation is explained by a declared injection:

"Professor Rivolta and I carried out the embalming shortly after death, but we did not undress him and removed nothing [of his organs]; we injected a liquid based on formalin mixed with other substances." — Professor Cordiglia, deposition cited by Bouflet, op. cit., p. 394^[70]

Bouflet notes that an identical treatment was applied to the body of Pope John XXIII, who died on 3 June 1963:

"A similar post-mortem treatment was applied with equal success to the body of Pope John XXIII, after his death on 3 June 1963." — Joachim Bouflet, op. cit., p. 395^[71]

This point deserves to be stated plainly: the highly publicized preservation of the body of John XXIII, displayed since 2001 beneath the altar of Saint Jerome in Saint Peter's Basilica, is the result of a documented post-mortem preservative treatment, not of an unexplained phenomenon. It must not be presented as a case of miraculous incorruption alongside the dossiers examined above.

Selection bias: the cases not preserved

The methodologically most solid objection is that of selection bias. Among tens of thousands of saints, blesseds, and venerables over the twenty centuries of Church history, only 102 cases of notable incorruption were compiled by Cruz. The other bodies — the vast majority — decomposed normally. Why these 102 and not the others? Only remarkable cases are selected and reported; the unpreserved cases give rise to no accounts or dossiers.^[72]

Moreover, the devotional pressure surrounding canonization proceedings encouraged communities to exaggerate the state of preservation: a "well-preserved" body became "intact," then "perfectly intact," as the accounts accumulated.

The limits of the examination protocol

Many older examinations do not meet the criteria of a modern forensic investigation. The doctors present were often few in number, their methods were not standardized, the reports were written after the exhumation on the basis of brief notes, and the surrounding atmosphere of devotion could influence their perceptions. The examinations of contemporary cases — such as that of Padre Pio in 2008 — are more rigorous.

"During the exhumation of Padre Pio in March 2008, 40 years after his death, the body showed partial saponification of the skull and upper limbs, while fragments of flesh remained on the knees, hands, and feet. The fresh plaster used during the burial had generated excessive moisture." — Portale Ufficiale di Padre Pio, report on the exhumation of March 2, 2008^[73]

This case illustrates both the limits of the popular notion of incorruption (Padre Pio's body does not resemble a sleeping person) and the honesty of the Catholic institution, which does not conceal these data.

Recognizing the value of the scientific objections does not mean they exhaust all cases. Several phenomena resist ordinary naturalistic explanations.

The liquid of Charbel: a documented exudation spanning nearly thirty years

In the case of Saint Charbel, the exudation of a liquid, visually identified as plasma by Dr. Choukrallah, continued from 1899 until the 1927 examination.^[74] What the two successive medical commissions — that of 1927 and that of 1950 — established is not a total absence of decomposition, but the failure of every preservative hypothesis tested: neither tannin, nor arsenic, nor mercury, nor formalin, nor lead, nor copper, nor zinc explains the persistent moisture found on the body and the coffin in 1950, even though the general environment of the crypt showed no such condensation.^[75] The commissioners of 1950 explicitly limited themselves, in their final wording, to recording the fact without declaring it miraculous — exactly the position of prudence that this dossier calls for.^[76]

The prolonged flexibility of the joints

Rigor mortis normally sets in two to six hours after death and disappears within forty-eight to seventy-two hours. After this period, a dead body becomes progressively and permanently rigid through the processes of decomposition and desiccation. Recurring testimonies report supple joints at exhumations carried out several years or decades after death — as in the case of Catherine Labouré (flexibility attested by the examining physician in 1933, 57 years after death). This flexibility is difficult to explain through natural preservation mechanisms alone.

Inexplicable fragrances

Consistent testimonies, from the earliest centuries to the present day, report sweet and indescribable fragrances emanating from the bodies of certain saints at the time of exhumation or translation. This feature is independent of embalming (which uses chemicals with a distinct smell) and of mummification (which generally produces a smell of dried leather or no smell at all). It is one of the traits noted in the dossiers studied by Thurston as the most difficult to explain naturally.^[77]

Benedict XIV and canonical prudence

The Catholic Church formalized its prudence on this subject in the eighteenth century through Benedict XIV. His rule is clear and non-negotiable in current canonical procedure: incorruption is not a sign of holiness in itself, and cannot serve as a miracle for a canonization, unless all natural causes have been rigorously excluded — which is practically impossible to demonstrate definitively.

This rule protects faith against two extremes: credulity (any preserved body would be a miracle) and closed skepticism (no preservation could be supernatural). The Church leaves the phenomenon in a zone of possible signum, not of certain probatio.

The modern canonization process: medical miracles

Since the reform of canonical procedures under John Paul II (Divinus Perfectionis Magister, 1983), the miracles required for beatification and canonization are medical miracles carefully examined by commissions of independent doctors convened by the Congregation for the Causes of Saints.^[78] These commissions examine medically inexplicable healings, documented with modern clinical records. Bodily incorruption no longer plays a part in this process.

Thus, John Paul II was canonized on the miraculous healing of Sister Marie Simon-Pierre from Parkinson's disease (2011), not on the state of his body at exhumation. Bernadette Soubirous was canonized on the dossier of the Lourdes apparitions and her heroic virtues, not solely on her preserved body. This clarification is decisive.

How to read incorruptible bodies today

The contemporary Catholic position can be formulated as follows: when faced with a body preserved in an inexplicable way, the Church invites a triple prudence:

1. Scientific prudence: rigorously rule out natural causes (embalming, adipocire, tomb conditions) before drawing any conclusion.
2. Hagiographic prudence: assess the entire dossier of holiness, not the state of the body alone. A preserved body without virtue, without charity, without ecclesial obedience means nothing.
3. Theological prudence: even if the phenomenon is unexplained, it remains a possible sign, not a proof of holiness nor a criterion of canonization. God alone knows why some bodies are preserved and others are not.

This triple prudence is not a skeptical evasion: it is the mark of an adult faith, which does not seek to prove God through curiosities, but to read the signs He gives in history.

The four properties of the glorified body according to Thomas Aquinas

Thomas Aquinas, in the Supplement to the Summa Theologiae (Questions 82–85), sets out the doctrine of the four properties of the glorified body at the resurrection:^[79]

1. Impassibility (impassibilitas): the risen body can no longer suffer, be destroyed, or be affected by external agents (Q82, a1).
2. Brightness (claritas): the body radiates the glory of the soul united to it in the beatific vision (Q85, a1).
3. Agility (agilitas): the body obeys the soul perfectly in movement, without hindrance or fatigue (Q84, a1).
4. Subtlety (subtilitas): the body is no longer subject to ordinary material obstacles (Q83, a1).

Impassibility is the property most directly linked to incorruptibility: a glorified body can no longer decompose because it can no longer undergo alteration. If Thomas sees in the preserved bodies of the saints a possible anticipation of eschatological glory, it is precisely because temporal incorruption evokes eternal incorruptibility.

« It belongs to the perfection of the glorified body to be incorruptible, not because it possesses no matter subject to corruption, but because the form communicated to it by the glorified soul entirely excludes the potency to corruption. » — Thomas Aquinas, Summa Theologiae, Supplementum, Q82, a1^[80]

The Catechism of the Catholic Church and the resurrection of the body

The Catechism of the Catholic Church teaches:

« What God has done in Christ, he will give to us by his power. "It is sown in corruption, it rises in incorruptibility. It is sown in dishonour, it rises in glory. It is sown in weakness, it rises in power" (1 Cor 15:42–43). » — CCC §997, quoting Saint Paul, 1 Corinthians 15:42–43^[81]

CCC §990 states: « The "resurrection of the flesh" (the phrase used in the Apostles' Creed) means that after death our immortal soul will live on, and that our "mortal bodies" (Rom 8:11) will also rise again to life. »

The Pauline articulation is fundamental: the present body, sown "in corruption", will rise "in incorruptibility". Incorruptibility is an eschatological attribute — it belongs fully to the glorified body after the resurrection. The incorruptible bodies of the saints throughout history can be read as anticipatory signs of this ultimate destiny of the human body.

Incorruptible bodies and Christian hope

This theological reading is decisive for understanding why the Catholic tradition has always attached particular importance to holy bodies. Christianity believes that matter is not a by-product of the spirit, that the body is not a prison of the soul from which one must escape (the Gnostic and Platonic thesis), but that the human body is called to glory — to a resurrection that transforms it without abolishing it.

« The Christian hope of the resurrection casts a new light on death. For if the body is destined to rise again, then it is not indifferent that it be treated with respect and veneration. The incorruptibility of certain holy bodies may be understood as a sign given to the Church along the way: the body is good, it is loved by God, it will be glorified. » — Cardinal Joseph Ratzinger, Eschatology — Death and Eternal Life, Desclée, 1979^[82]

The emotion that incorruptible bodies arouse in the pilgrims who venerate them is therefore not a superstition without foundation: it is the popular intuition of a profound theological truth — that death does not have the last word over matter, that the holy body is promised to glory, and that certain bodies, in the history of the Church, seem to bear its visible sign.

Liturgical veneration and its foundation

The Council of Nicaea II (787 AD), in its decrees on the veneration of images, implicitly confirms the legitimacy of the veneration of the relics of the saints:^[83] the bodies and relics of martyrs and saints are bound to the holiness of the soul that dwelt in them, and as such merit a veneration inferior to that due to God alone (dulia and not latria).

Saint John Chrysostom had already developed this theme:

« The bodies of the saints, even when they are dead, have such energy that when one touches them, when one venerates them, when one embraces them, they rekindle our soul and restore to it all its vigour. » — Saint John Chrysostom, Homilies on 2 Corinthians, homily XXVI^[84]

The gift of bodily holiness in Catholic mysticism

The Catholic mystical tradition recognises, in the bodies of the saints, a bodily inscription of grace. The body that has participated in the sacraments, that has offered itself in penance and charity, that has been the temple of the Holy Spirit, bears within itself a form of divine memory that death does not always seem able to erase.

« My flesh also dwells secure, for thou wilt not abandon my soul to Sheol, nor let thy holy one see corruption. » — Psalm 16 (15):9–10, quoted by Saint Peter as a prophecy of the resurrection of Christ (Acts 2:27), and applied by tradition to the saints^[85]

This psalmic verse, which the patristic tradition read as a promise of the eschatological incorruptibility of the saints, sums up the faith that underlies the veneration of incorruptible bodies: not a magic of the holy body in itself, but God's fidelity to those who belong to him.
