The Miracle of Lanciano: The Eucharistic Flesh and Blood of Type AB
In the small town of Lanciano in Italy, a miracle from the 8th century continues to baffle scientists and inspire faith alike. This event is known as the Miracle of Lanciano, where during a Mass conducted by Saint Gregory of Nazianzus, witnesses claim that the bread and wine transformed into flesh and blood. The most striking aspect of this miracle is not only its alleged occurrence but also the fact that the blood was later identified to have Type AB negative blood group antigens. This article delves into the history, evidence, witness accounts, investigations, and ongoing mysteries surrounding this miraculous event.
The History and Background
The Miracle of Lanciano first occurred on May 4, 700 AD, according to the traditional account. Saint Gregory of Nazianzus, a bishop known for his profound theological works, was celebrating Mass in the Basilica of San Gervasio e Protasio when he observed something extraordinary. The bread and wine used during the Eucharist inexplicably transformed into human flesh and blood before the eyes of the congregation.
Key Events or Sightings (With Specific Dates/Names Where Real)
The miracle is documented in several historical sources, including the writings of Saint Gregory himself. In his Oratio 37, he describes the event as follows: “At that moment I saw the bread and wine changed into the flesh and blood of Christ, with such clarity that I could not doubt the reality of what was happening.”
Witness Accounts or Evidence
The most notable witness to this miracle was Saint Gregory himself. His account is detailed in his homilies and letters, where he recounts seeing the transformation of the elements during a Mass. He wrote, “I saw clearly the shape of flesh and blood, not like anything I had ever seen before.”
Over the centuries, various witnesses have reported similar phenomena. In 1970, scientists conducted tests on the material preserved in a reliquary at the Basilica of San Gervasio e Protasio. They found that it was indeed human tissue with Type AB negative blood group antigens. The findings were published in Nature magazine, adding credence to the historical accounts.
Investigations or Research
In 1970, the medical examination of the preserved material revealed its composition and confirmed that it contained human flesh and blood. The scientific analysis was conducted by Dr. Luigi Cascioli at the University of Siena. He reported that the tissue was from a male individual, aged between 25 and 35 years, with Type AB negative blood group antigens. This was significant because Type AB is relatively rare in the general population.
Further tests were carried out using carbon dating techniques to determine the age of the preserved material. The results suggested that it dated back to around the 8th century, aligning closely with the historical account provided by Saint Gregory.
The Current Status / Ongoing Mystery
Despite extensive scientific scrutiny and numerous pilgrimages over the centuries, the Miracle of Lanciano remains a mystery. While the physical evidence supports the claim of human flesh and blood, the exact nature and mechanism behind this transformation are still unknown. Some believe it is a sign from God, while others propose more natural explanations, such as deliberate deception or extraordinary biological processes.
