What happened
In a small church in Lanciano, around the year 750, a monk was saying Mass while quietly losing his faith in the words he spoke each day — that the bread and wine truly become the Body and Blood of Christ.
At the consecration, the host changed in his hands: the bread became visible flesh, the wine became blood that coagulated into five pellets. Both have been preserved, without any preservative, for nearly thirteen centuries — and are still displayed in a monstrance today.
What science found
SolidIn 1970–71, Prof. Odoardo Linoli examined the relics: the flesh is human heart muscle (myocardium), the blood is type AB. It remains the only Eucharistic miracle published in a peer-reviewed medical journal — though it has never been independently replicated.
Where it stands
Venerated for nearly thirteen centuries, with ecclesiastical acknowledgements from 1574 onward. The scientific cornerstone.
Church recognition is a judgment about devotion — not a claim of scientific proof. We keep the two distinct.

The bigger picture
This case is one witness in a much longer story — the Catholic teaching that Christ is truly, substantially present in the Eucharist.
