Eucharistic miracles

Each mark is one quotation. Touch the timeline to read it.

The Church teaches that at every Mass the bread and wine become the Body and Blood of Christ while their appearances remain. From time to time a visible sign connected with a consecrated Host has been reported. This timeline gives a number of those reports in date order, with what the linked source says about witnesses, investigations, scientific examinations, the Church's response, and where the relic is kept. It also gives the teaching that frames them.

Drafted from primary and official sources. Every quotation is checked against the page it links to. Each fact listed under an entry is stated on that entry's linked page. Most of the early accounts rest on tradition and on later papal or diocesan statements, not on reports written at the time, and the notes say so. For the recent cases the timeline gives the local bishop's own wording, which in no case here is a formal declaration of a miracle. The entries are a selection. Several well-known cases are left out because no official page for them could be read.

The Eucharistic miracle of Lanciano

Pope St. John Paul II Letter to Archbishop Carlo Ghidelli of Lanciano-Ortona, 4 October 2004, 2

“This is particularly true for the city of Lanciano, custodian of two Eucharistic miracles which, in addition to being very dear to the faithful of Frentania, make it the destination of many pilgrimages from Italy and the whole world. I would like to recall that when I was the Cardinal of Krakow, I myself visited the Church of St Francis in Lanciano where the relics are preserved of the famous miracle that dates back to the eighth century.”

The Eucharistic miracle of Lanciano

Vatican News (Federico Piana) Miracoli eucaristici, faro di fede anche nei momenti di crisi, 13 June 2020

“Lanciano, in the province of Chieti, is the scene of another extraordinary Eucharistic miracle. It took place presumably between 720 and 750. Its protagonist is a Basilian monk, he too gripped by a doubt about the real presence of the Lord in the Eucharist. One day, during the celebration, the bread is transformed into a piece of flesh and the wine into blood, before his astonished eyes.”

Our translation. The words as written, in Italian:

“Lanciano, in provincia di Chieti, è il teatro di un altro, straordinario, miracolo eucaristico. Avvenuto presumibilmente tra il 720 ed il 750, vede protagonista un monaco basiliano, anch’egli attanagliato da un dubbio sulla reale presenza del Signore nell’Eucaristia. Un giorno, durante la celebrazione, il pane si trasforma in un pezzo di carne ed il vino in sangue, sotto i suoi occhi stupefatti.”

“At the initiative of Archbishop Pacifico Perantoni of Lanciano, and of the provincial minister of the Franciscan Conventuals of Abruzzo, and with authorization from Rome, in November 1970 the Franciscans of Lanciano decided to have the relics examined scientifically. Linoli was entrusted with the study. He was assisted by Dr. Ruggero Bertelli, retired professor of human anatomy at the University of Siena. … He presented his findings on March 4, 1971. His study confirmed that the flesh and blood were of human origin. The flesh was unequivocally cardiac tissue, and the blood was of type AB.”

The Host of Alatri

Pope Gregory IX Bull Fraternitatis tuae, 1228, in the Italian translation published by the Diocese of Anagni-Alatri

“We have received your letter, dearest brother, which informed us how a certain young woman, swayed by the bad advice of a wicked woman, after receiving the most holy Body of Christ from the hands of the priest, kept it in her mouth until, seizing a favourable moment, she was able to hide it in a cloth, where, after three days, she found the same body that she had received in the form of bread transformed into flesh, as anyone can still see with his own eyes. … In the first place we must give thanks, with all our strength, to him who, while working wonderfully in all things, nevertheless on some occasions repeats miracles and raises up new prodigies”

Our translation. The words as written, in Italian:

“Abbiamo ricevuto la tua lettera, fratello carissimo, che ci informava, come una certa giovane suggestionata dal cattivo consiglio di una malefica donna, dopo aver ricevuto dalle mani del Sacerdote il Corpo santissimo di Cristo, lo trattenne nella bocca fino al momento in cui, colta l'occasione favorevole, lo poté nascondere in un panno, dove, dopo tre giorni, ritrovò lo stesso corpo che aveva ricevuto in forma di pane, trasformato in carne, come tuttora ognuno può constatare con i propri occhi. … In primo luogo dobbiamo rendere grazie, con tutte le nostre forze, a colui che pur operando in ogni cosa in modo meraviglioso, tuttavia in qualche occasione ripete i miracoli e suscita nuovi prodigi”

The Eucharistic miracle of Bolsena

Pope Benedict XVI General Audience, 17 November 2010

“Indeed, he ordered that the famous Corporal with the traces of the Eucharistic miracle which had occurred in Bolsena the previous year, 1263, be kept in Orvieto Cathedral — where it still is today. While a priest was consecrating the bread and the wine he was overcome by strong doubts about the Real Presence of the Body and Blood of Christ in the sacrament of the Eucharist. A few drops of blood began miraculously to ooze from the consecrated Host, thereby confirming what our faith professes.”

Miracle

The Eucharistic miracle of Bolsena

Pope St. Paul VI Angelus, 8 August 1976

“Bolsena is famous for its miracle, which took place in 1263, when a Bohemian priest, a pilgrim passing through, celebrating Holy Mass on the altar of the martyr who is still so honoured at Bolsena, and tormented by doubt about the real presence of Jesus Christ in the Eucharist, that is, about the "transubstantiation" of the bread and wine into the Body and Blood of the Lord, sees that the Blood wets the small cloth, called the Corporal, on which the holy rite of the Eucharistic sacrifice is carried out. Wonder and amazement among those present. At once the sacred Corporal, stained with the divine Blood, was carried to nearby Orvieto, where the Pope then resided, our distant predecessor Urban IV (1261-1264), who, having verified the prodigy, instituted the feast of Corpus Christi”

Our translation. The words as written, in Italian:

“Bolsena è celebre per il suo miracolo, avvenuto nel 1263, quando un Sacerdote boemo pellegrino di passaggio, celebrando la S. Messa sull’altare della martire, ancora tanto onorata a Bolsena, tormentato dal dubbio circa la reale presenza di Gesù Cristo nell’Eucaristia, cioè circa la «transustanziazione» del pane e del vino nel Corpo e nel Sangue del Signore, vede che il Sangue bagna la piccola tovaglia, detta Corporale, sulla quale è compiuto il santo rito del sacrificio eucaristico. Meraviglia e stupore dei presenti. Subito il sacro Corporale, macchiato dal Sangue divino, fu portato alla vicina Orvieto, dove allora risiedeva il Papa, nostro lontano predecessore, Urbano IV (1261-1264), il quale, verificato il prodigio, istituì la festa del « Corpus Domini »”

Miracle

The Eucharistic miracle of Bolsena

Pope St. John Paul II Homily for Corpus Christi, Orvieto Cathedral, 17 June 1990, 3

“Even though its construction is not directly connected with the solemnity of Corpus Christi, instituted by Pope Urban IV with the bull Transiturus in 1264, nor with the miracle that took place at Bolsena the year before, it is nonetheless beyond doubt that the Eucharistic mystery is powerfully evoked here by the corporal of Bolsena, for which the chapel that now jealously guards it was specially built. Since then the city of Orvieto has been known throughout the world for this miraculous sign, which reminds everyone of the merciful love of God, who made himself the food and drink of salvation for humanity on pilgrimage on earth.”

Our translation. The words as written, in Italian:

“Anche se la sua costruzione non è collegata direttamente alla solennità del “Corpus Domini”, istituita dal Papa Urbano IV con la bolla Transiturus, nel 1264, né al miracolo avvenuto a Bolsena l’anno precedente, è però indubbio che il mistero eucaristico è qui potentemente evocato dal corporale di Bolsena, per il quale venne appositamente fabbricata la cappella, che ora lo custodisce gelosamente. La città di Orvieto è da allora conosciuta nel mondo intero per tale segno miracoloso, che a tutti ricorda l’amore misericordioso di Dio, fattosi cibo e bevanda di salvezza per l’umanità pellegrina sulla terra.”

Miracle

St. Thomas Aquinas on flesh or blood seen in the Host

St. Thomas Aquinas Summa Theologiae III, q. 76, a. 8, I answer that

“Such apparition comes about in two ways, when occasionally in this sacrament flesh, or blood, or a child, is seen. Sometimes it happens on the part of the beholders, whose eyes are so affected as if they outwardly saw flesh, or blood, or a child, while no change takes place in the sacrament. … But it sometimes happens that such apparition comes about not merely by a change wrought in the beholders, but by an appearance which really exists outwardly. And this indeed is seen to happen when it is beheld by everyone under such an appearance, and it remains so not for an hour, but for a considerable time”

The Eucharistic miracle of Cascia

Monastery of St. Rita, Cascia Il Beato Simone Fidati e il Miracolo eucaristico

“The Eucharistic miracle of Cascia took place in 1330, at Siena. In that year a priest, called to attend a dying peasant, put the consecrated host in the parchment of his breviary. After hearing the sick man's confession, he opened the book and saw that the host was giving out blood and had stuck to the page. The priest said he would come back later and went to speak with Brother Simon of Cascia, who was preaching in the city. … Brother Simon, with the priest's consent, took away with him the two bloodstained pages with the liquefied host.”

Our translation. The words as written, in Italian:

“Il miracolo eucaristico di Cascia è avvenuto nel 1330, a Siena. In quell’anno, un sacerdote, chiamato ad assistere un contadino moribondo, mise l’ostia consacrata nella pergamena del suo breviario. Dopo aver confessato il malato, aprì il libro e vide che l’ostia emanava sangue e si era attaccata alla carta. Il sacerdote disse che sarebbe tornato più tardi e andò a parlare con Fra Simone da Cascia, che stava predicando in città. … Fra Simone, con il consenso del sacerdote, portò con sé le due pagine insanguinate con l’ostia liquefatta.”

The Miracle of Turin

Archdiocese of Turin Memoria del «Miracolo di Torino» alla Basilica del Corpus Domini, Brevi cenni storici (June 2025)

“The stolen objects had been loaded on a mule which, according to the account, stopped in front of the church of San Silvestro, refusing to go on and sinking to the ground. The host, which came out of the baskets loaded on the mule, did not fall to the ground but, according to the testimonies, is said to have remained suspended in the air for a long time, until the bishop arrived, and to have come down again at the Gospel invocation "Lord, stay with us!". The basilica of Corpus Domini was built on the place where the miracle happened.”

Our translation. The words as written, in Italian:

“Gli oggetti trafugati erano stati caricati su un mulo che, secondo il racconto, si fermò davanti alla chiesa di San Silvestro, rifiutandosi di proseguire e accasciandosi al suolo. L’ostia, fuoriuscita dalle ceste caricate sul mulo, non cadde a terra ma, secondo e testimonianze, sarebbe rimasta sospesa in aria per lungo tempo, fino all’arrivo del vescovo, e sarebbe ridiscesa all’invocazione evangelica “Signore, resta con noi!”. Sul luogo dove avvenne il miracolo fu eretta la basilica del Corpus Domini.”

“the business of the monstrance rising above the flames, if it had taken place only in front of a few rather sleepy monks, one could have said afterwards that it was a fine hoax; but since there were thousands of witnesses, who were not all asleep, and some of whom were even fasting, then unless one is badly informed one cannot say that it is a hoax.

“On the eve of the Assumption in 1730, while the whole population was crowded into the Cathedral for the "Procession of the Candles and Tributes", the historic civic homage of the City of Siena to its Patroness, some criminals got into the Church of St Francis of the Conventual Friars Minor where, having broken the little door of the Tabernacle, they took the ciborium, which held about 350 hosts consecrated shortly before. … On 17 August the Holy Hosts were found in the alms box of the nearby Collegiate Church of St Mary in Provenzano, among coins, dust and cobwebs; after official verification by the Church authority, they were carried back in procession to the Church of St Francis”

Our translation. The words as written, in Italian:

“Alla vigilia dell’Assunta del 1730, mentre l’intera popolazione era assiepata in Cattedrale per la celebrazione del "Corteo dei Ceri e dei Censi", omaggio civile storico della Città di Siena alla sua Patrona, alcuni malfattori si introdussero nella Chiesa di San Francesco dei Frati Minori Conventuali dove, rotta la porticina del Tabernacolo, si impossessarono della Pisside che conteneva circa 350 particole da poco consacrate. … Il 17 agosto le SS. Particole vennero ritrovate nella cassetta delle elemosine della vicina Collegiata di S.

“Another fragment of a Host, placed on a platinum plate moistened with a few drops of a saturated solution of iodine in water, quickly and wholly took on a fine blue colour, a sure proof of the presence of normal starch in the Host. … In conclusion we answer the questions put to us: 1.

Leo XIII on prodigies in honour of the Eucharist

Pope Leo XIII Mirae Caritatis, 7 (28 May 1902)

“And this miracle, itself the very greatest of its kind, is accompanied by innumerable other miracles; for here all the laws of nature are suspended; the whole substance of the bread and wine are changed into the Body and the Blood; the species of bread and wine are sustained by the divine power without the support of any underlying substance; the Body of Christ is present in many places at the same time, that is to say, wherever the Sacrament is consecrated. And in order that human reason may the more willingly pay its homage to this great mystery, there have not been wanting, as an aid to faith, certain prodigies wrought in His honour, both in ancient times and in our own, of which in more than one place there exist public and notable records and memorials.”

“In the most blessed sacrament of the Eucharist "the body and blood, together with the soul and divinity, of our Lord Jesus Christ and, therefore, the whole Christ is truly, really, and substantially contained." "This presence is called 'real' - by which is not intended to exclude the other types of presence as if they could not be 'real' too, but because it is presence in the fullest sense: that is to say, it is a substantial presence by which Christ, God and man, makes himself wholly and entirely present."”

This change the holy Catholic Church has fittingly and properly called transubstantiation."”

The Eucharistic event at Sokółka

Metropolitan Curia of Białystok (Fr. Andrzej Kakareko, chancellor) Communiqué, Białystok, 14 October 2009

“On 7 January 2009 a sample was taken from the Host, and it was then examined independently by two professors, specialists in pathomorphology, of the Medical University of Białystok. They gave a concordant finding, which reads: "the material sent for assessment (…) in the judgment of two independent pathomorphologists (…) indicates heart muscle tissue, or at least, of all the living tissues of the organism, it most resembles it". The Commission established that the Host from which the sample for the expert report was taken is the same one that was moved from the sacristy to the tabernacle in the chapel of the rectory. No interference by outside persons was found. The records of the case have been sent to the Apostolic Nunciature in Warsaw. The event at Sokółka does not contradict the faith of the Church, but rather confirms it.”

“Dnia 7 stycznia 2009 roku z Komunikantu pobrano próbkę, która następnie została niezależnie zbadana przez dwóch profesorów specjalistów patomorfologów z Uniwersytetu Medycznego w Białymstoku. Wydali oni zgodne orzeczenie, które brzmi: „przysłany do oceny materiał (…) w ocenie dwóch niezależnych patomorfologów (…) wskazuje na tkankę mięśnia sercowego, a przynajmniej, ze wszystkich tkanek żywych organizmu najbardziej ją przypomina”. Komisja ustaliła, że Komunikant, z którego została pobrana próbka do ekspertyzy jest tym samym, który został przeniesiony z zakrystii do tabernakulum w kaplicy na plebanii. Ingerencji osób postronnych nie stwierdzono. Akta sprawy zostały przekazane do Nuncjatury Apostolskiej w Warszawie. Wydarzenie z Sokółki nie sprzeciwia się wierze Kościoła, a raczej ją potwierdza.”

Wszyscy byli głęboko poruszeni tym, co zobaczyli. Ks. Arcybiskup zalecił Komunikant zabezpieczyć oraz czekać i obserwować, co dalej będzie się z Nim działo. … Komunikant był w ten sposób przechowywany przez trzy lata, aż do uroczystego przeniesienia go do kościoła 2 października 2011 roku.”

“This communiqué, published on 10 April 2016, spoke "[…] of the event that took place in the parish of St. Hyacinth in Legnica and which has the hallmarks of a Eucharistic miracle" … The tests were carried out independently in two centres: the Department of Forensic Medicine in Wrocław and the Department of Forensic Medicine of the Pomeranian Medical University in Szczecin. In the communiqué Bishop Kiernikowski quoted the final finding of the Department of Forensic Medicine: In the histopathological image, tissue fragments were found containing fragmented parts of striated muscle. … is most similar to heart muscle […] with changes that often accompany the agony”

“Komunikat ten, ogłoszony 10 kwietnia 2016 r., mówił „[…] o wydarzeniu, jakie zaszło w parafii św.

The Eucharistic event at Legnica

Vatican News (Karol Darmoros) Legnica: Relikwia Ciała Pańskiego przyciąga cały świat, 3 July 2026

“The Eucharistic Event in Legnica concerns a Host which fell to the floor on 25 December 2013 during the giving of Holy Communion. After it was placed in a vessel of water, red discolorations appeared. A commission appointed by the Bishop ordered tests, and in his communiqué the then diocesan bishop, Zbigniew Kiernikowski, stated that the histopathological image was "most similar to heart muscle", with changes that "often accompany the agony". Genetic tests pointed to tissue of human origin. In 2016, in keeping with the recommendations of the Holy See, the Bishop of Legnica directed that a place be prepared for the exposition of the Relic, so that the faithful could venerate it.”

Our translation. The words as written, in Polish:

“Wydarzenie Eucharystyczne w Legnicy wiąże się z Hostią, która 25 grudnia 2013 r. upadła na posadzkę podczas udzielania Komunii świętej. Po złożeniu jej w naczyniu z wodą pojawiły się czerwone przebarwienia. Powołana przez Biskupa komisja zleciła badania, a w komunikacie ówczesny ordynariusz Zbigniew Kiernikowski wskazał, że obraz histopatologiczny był „najbardziej podobny do mięśnia sercowego”, ze zmianami, które „często towarzyszą agonii”. Badania genetyczne wskazały na ludzkie pochodzenie tkanki. W 2016 r., zgodnie z zaleceniami Stolicy Apostolskiej, biskup legnicki polecił przygotowanie miejsca wystawienia Relikwii, aby wierni mogli oddawać jej cześć.”

A Vatican documentary on recent cases

Vatican News (Francesca Merlo) Eucharistic miracles: Faith is not humbled by science, 30 October 2018

“Science can be used, and has been used, to refute miracles. This was the case in one church in Poland, where red stains were discovered on a host. After having it tested, it was discovered that the red was simply fungus. Science is also used to accept miracles, as was the case in the situations explored in the documentary.”

How the Church now rules on reported supernatural events

Dicastery for the Doctrine of the Faith Norms for Proceeding in the Discernment of Alleged Supernatural Phenomena, I, 23 (17 May 2024)

“In light of the aforementioned points, it is reaffirmed that, as a rule, neither the Diocesan Bishop, nor the Episcopal Conferences, nor the Dicastery will declare that these phenomena are of supernatural origin, even if a Nihil obstat is granted (cf. Par. 11, above). It remains true, however, that the Holy Father can authorize a special procedure in this regard.”
