An inscription in marble from the 17th century describes this Eucharistic miracle which occurred at Lanciano in 750 at the Church of St. Francis. “A monastic priest doubted whether the Body of Our Lord was truly present in the consecrated Host. He celebrated Mass and when he said the words of consecration, he saw the Host turn into Flesh and the Wine turn into Blood. Everything was visible to those in attendance. The Flesh is still intact and the Blood is divided into five unequal parts which together have the exact same weight as each one does separately.
In 1970, the Archbishop of Lanciano and the Provincial Superior of the Conventual Franciscans at Abruzzo, with Rome's approval, requested Dr. Edward Linoli, director of the hospital in Arezzo and professor of anatomy, histology, chemistry, and clinical microscopy, to perform a thorough scientific examination on the relics of the miracle which had occurred twelve centuries earlier. On March 4, 1971, the professor presented a detailed report of the various studies carried out. Here are the basic results:
- The “miraculous flesh" is authentic flesh consisting of muscular striated tissue of the myocardium.
- The “miraculous Blood" is truly blood. The chromatographic analysis indicated this with absolute and indisputable certainty.
- The immunological study shows with certitude that the flesh and the blood are human, and the immuno – hematological test allows us to affirm with complete objectivity and certitude that both belong to the same blood type AB, the same blood type as that of the man of the Shroud and the type most characteristic of Middle Eastern populations.
- The proteins contained in the Blood have the normal distribution, in the identical percentage as that of the serous-proteic chart for normal fresh blood.
- No histological dissection has revealed any trace of salt infiltrations or preservative substances used in antiquity for the purpose of embalming.
Professor Linoli also discarded the hypothesis of a hoax carried out in past centuries. This report was published in The Sclavo Notebooks in Diagnostics (Collection #3, 1971) and aroused great interest in the scientific world. Also, in 1973, the chief Advisory Board of the World Health Organization appointed a scientific commission to corroborate Linoli's findings. Their work lasted 15 months and included 500 tests. Their research was the same as that carried out by Professor Linoli, with further additions. With even greater precision, it was verified that the fragments taken from Lanciano could in no way be likened to embalmed tissue. As to the nature of the fragment of Flesh, the commission declared it to be living tissue because it responded rapidly to all the clinical reactions distinctive of living beings. The Flesh and the Blood of Lanciano are therefore just the same as they would be if they had been taken from a living being on the same day. This reply therefore fully corroborated Professor Linoli's conclusions. In the extract summarizing the scientific work of the Medical Commission of the World Health Organization and the United Nations, published in December of 1996 in New York and Geneva, declared that science, aware of its limits, has come to a halt, face to face with the impossibility of giving an explanation.
