The claims

In the final book of City of God (c. 426 CE), Augustine of Hippo compiled approximately seventy attested miracle accounts from his own diocese, presenting them as evidence that miracles had not ceased with the apostolic age.

The Venerable Bede, in his Prose Life of St. Cuthbert (c. 721 CE) and Ecclesiastical History (731 CE), catalogues dozens of miracles by the Northumbrian bishop including post-mortem healings from his incorrupt body.

Following cremation of Buddhist monks, small crystal or bead-like objects called sarira are frequently recovered from the ashes and venerated as signs of spiritual attainment — a phenomenon spanning multiple centuries and cultures.

A German priest celebrating Mass in Bolsena reportedly experienced a bleeding host that stained the corporal linen; the event allegedly prompted Pope Urban IV to institute the Feast of Corpus Christi.

A 13th-century account describes a consecrated host stolen for a sorceress beginning to bleed, leading to its veneration in Santarém, Portugal, where it is still displayed in a crystal reliquary.

A five-year-old Lummi boy's rapidly progressing necrotizing fasciitis stopped spreading and he made a full recovery after his family placed a relic of Kateri Tekakwitha on his body.

Relics claimed to be the charred remains of Joan of Arc, held in a Chinon pharmacy bottle since 1867, were analyzed in 2009–2010 by a multidisciplinary forensic team and confirmed to be a mummified cat leg bone and a human rib dating to the 6th–3rd century BC — Egyptian mummy components, not Joan's remains.

John Vianney's body was found dried and darkened after death and bears a wax mask over the face; his heart, removed in 1904, is separately venerated as a first-class relic and described as incorrupt, though it has undergone a century of conservation treatment.

When John XXIII was exhumed in 2001 after 37 years, his face appeared intact and serene; the Vatican explicitly attributed this to embalming with formalin, hermetic sealing in multiple coffins, and Prof. Golia's proprietary preservation treatment — not to miracle.

When a sarcophagus believed to contain Saint Cecilia was opened in 1599, witnesses reported finding a body in a distinctive position; sculptor Stefano Maderno created an exact marble replica — but no witness actually saw her face, and historians dispute the account.

Silvan, claimed to be the oldest incorrupt body in the Catholic Church, is on display at a Croatian church; skeptical examination reveals the 'body' is a wax sculpture with painted features, glued-on eyebrows and wig, and artificially shallow nostrils and ear canals.

An Italian nun dying from a post-operative gastric fistula recovered instantly after a piece of John XXIII's bed sheet was placed on her wound — the case used for his beatification.

At the 1903 canonization of Seraphim of Sarov, attended by 200,000 including Tsar Nicholas II, numerous healings were reported at the translation of his relics — even though the pre-canonization commission had found the body was NOT incorrupt.

A relic said to date from the 8th century — when a host and wine reportedly became flesh and blood — was analyzed in 1971 and reported to be human heart muscle and blood.

Augustine personally witnessed and documented the healing of Paulus, a Cappadocian man afflicted with convulsions, at the shrine of St. Stephen in Hippo c. 425 CE, and days later the healing of his sister Palladia at the same altar.

The body of Francis Xavier was declared incorrupt when returned to Goa in 1554, two years after his death, and remains on public display at the Basilica of Bom Jesus -- though the body has visibly deteriorated and lost limbs over centuries.

The 16th-century Russian monastic founder's relics, seized by Soviet authorities in 1918, survived a Bolshevik examination that expected to expose fraud, and were returned to his monastery in 1998 after rediscovery in a Leningrad anatomical museum.

Archbishop John Maximovitch (1896-1966), canonized in 1994, was found with largely incorrupt remains at a 1993 exhumation in San Francisco — his face, hands, and beard visibly preserved 27 years after death.

The body of the Lourdes visionary, displayed at Nevers, is often called incorrupt — but a wax mask covers the face, and natural preservation can account for the rest.

A sealed ampoule claimed to contain the dried blood of 4th-century martyr Januarius liquefies reliably three times per year in Naples, a phenomenon documented since at least 1389 that has failed to occur on roughly a dozen recorded occasions.

The icon central to Pontic Greek Orthodox identity, attributed by tradition to St. Luke the Evangelist, was secretly buried by monks in 1923 at the time of the Lausanne population exchange and successfully recovered and transferred to Greece in 1931.

A linen cloth bearing the faint image of a crucified man — revered as Christ's burial shroud, radiocarbon-dated to the medieval period, and disputed ever since.

After Vietnamese Buddhist monk Thich Quang Duc self-immolated in 1963, his heart was reportedly found intact after cremation, re-burned, and still remained unconsumed — a relic now enshrined at Xa Loi Pagoda that has not been independently scientifically examined.

Vincent de Paul was briefly believed incorrupt, but flooding in the vault caused full decomposition; his disarticulated bones were reassembled by surgeons and are now encased inside a wax effigy at the Vincentian mother house in Paris.
