The Documentation
On August 15, 1996, a discarded consecrated Host was placed in water according to standard protocol. Instead of dissolving, it developed reddish tissue and grew.
- The Archbishop who ordered the investigation was Jorge Bergoglio — now Pope Francis
- Dr. Ricardo Castañón Gómez, a former atheist, coordinated the scientific analysis
- A tissue sample was sent to New York for blind testing
- The primary examiner was Dr. Frederick Zugibe, a secular forensic pathologist and cardiologist at Columbia University
- He was not told where the sample came from or what it had been
The Witness
Zugibe analyzed the tissue and identified it as human heart muscle — specifically from the myocardium of the left ventricle near the heart valves.
- He found intact, active white blood cells — cells that typically disintegrate within 15 minutes outside a living body
- Professor John Walker (University of Sydney) later confirmed intact white blood cells in the same tissue six years after the event
- The blood type was AB, matching the Lanciano relic and the Shroud of Turin
When Zugibe was finally told the sample came from a communion wafer that had been sitting in water for three years, he stated: "How and why a piece of a human heart is still alive, sitting in distilled water, is totally beyond my comprehension."

On October 12, 2008, during Mass in Sokółka, Poland, a consecrated Host accidentally fell to the ground and was placed in water to dissolve — the standard liturgical procedure. Instead of dissolving, it formed a red, blood-like substance.
The Metropolitan Curia of Białystok commissioned an independent scientific analysis. Two professors of pathomorphology at the Medical University of Białystok were selected:
They examined the sample independently.
The Witnesses
Both professors concluded that the sample was human cardiac muscle in the agony of death — myocardial tissue showing segmentation and fragmentation of muscle fibers at the intercalated discs, a pattern consistent with a heart under extreme duress.
But the finding that elevates this case above all other Eucharistic miracles is what they saw under the electron microscope:
The human heart tissue was physically, inextricably interwoven with the fibers of the wheat bread.
It was not a piece of flesh dropped onto a wafer. It was not blood smeared on top. The bread and the flesh shared the same cellular matrix. At the microscopic level, baked wheat fibers and living human cardiac tissue were seamlessly spliced together.
