When we meditate on the primacy of Christ in all creation we cannot help but marvel at how He draws all things to Himself when He is lifted up in the Holy Eucharist where He is really present with His body, blood, soul and divinity. Although substantially present, nonetheless the appearance or accidents of bread and wine miraculously remain. In this way we eat of His flesh and drink of His blood in Holy Communion and He truly becomes our food and drink in the Holy Sacrifice of the Mass.

On rare occasions Our Lord works what is called a eucharistic miracle whereby not only the substance changes – transubstantiation – but even the accidents. In 1996 in the Archdiocese of Buenos Aires, Argentina, when the present Pope Francis was Auxiliary Bishop under Cardinal Quarracino, an amazing eucharistic miracle took place. He himself had it photographed and investigated and the results are astonishing. The video below draws this out:

Here is a segment describing the event written by Fr. M. Piotrowski:

Eucharistic Miracle in Buenos Aires

The weakening of faith in the real presence of the Risen Christ in the Eucharist is one of the most significant aspects of the current spiritual crisis. Jesus wants to strengthen our faith in His Eucharistic presence. That is why from time to time in the history of the Catholic Church He gives us signs–Eucharistic miracles that clearly underscore the fact that He, the Risen Lord Himself in the mystery of His Divinity and glorified humanity, is truly present in the Eucharist. The most recent Eucharistic miracle recognized by the Church authorities occurred in 1996 in the capital of Argentina–Buenos Aires.

A consecrated Host becomes flesh and blood

At seven o’clock in the evening on August 18, 1996, Fr. Alejandro Pezet was saying Holy Mass at a Catholic church in the commercial center of Buenos Aires. As he was finishing distributing Holy Communion, a woman came up to tell him that she had found a discarded host on a candleholder at the back of the church. On going to the spot indicated, Fr. Alejandro saw the defiled Host. Since he was unable to consume it, he placed it in a container of water and put it away in the tabernacle of the chapel of the Blessed Sacrament.

On Monday, August 26, upon opening the tabernacle, he saw to his amazement that the Host had turned into a bloody substance. He informed Cardinal Jorge Bergoglio (Auxiliary Bishop at that time, now Pope Francis), who gave instructions that the Host be professionally photographed. The photos were taken on September 6. They clearly show that the Host, which had become a fragment of bloodied flesh, had grown significantly in size. For several years the Host remained in the tabernacle, the whole affair being kept a strict secret. Since the Host suffered no visible decomposition, Cardinal Bergoglio decided to have it scientifically analyzed.

On October 5, 1999, in the presence of the Cardinal’s representatives, Dr. Castanon took a sample of the bloody fragment and sent it to New York for analysis. Since he did not wish to prejudice the study, he purposely did not inform the team of scientists of its provenance. One of these scientists was Dr. Frederic Zugiba, the well-known cardiologist and forensic pathologist. He determined that the analyzed substance was real flesh and blood containing human DNA. Zugiba testified that, “the analyzed material is a fragment of the heart muscle found in the wall of the left ventricle close to the valves. This muscle is responsible for the contraction of the heart. It should be borne in mind that the left cardiac ventricle pumps blood to all parts of the body. The heart muscle is in an inflammatory condition and contains a large number of white blood cells. This indicates that the heart was alive at the time the sample was taken. It is my contention that the heart was alive, since white blood cells die outside a living organism. They require a living organism to sustain them. Thus, their presence indicates that the heart was alive when the sample was taken. What is more, these white blood cells had penetrated the tissue, which further indicates that the heart had been under severe stress, as if the owner had been beaten severely about the chest.”

Two Australians, journalist Mike Willesee and lawyer Ron Tesoriero, witnessed these tests. Knowing where sample had come from, they were dumbfounded by Dr. Zugiba’s testimony. Mike Willesee asked the scientist how long the white blood cells would have remained alive if they had come from a piece of human tissue, which had been kept in water. They would have ceased to exist in a matter of minutes, Dr. Zugiba replied. The journalist then told the doctor that the source of the sample had first been kept in ordinary water for a month and then for another three years in a container of distilled water; only then had the sample been taken for analysis. Dr. Zugiba’s was at a loss to account for this fact. There was no way of explaining it scientifically, he stated. Only then did Mike Willesee inform Dr. Zugiba that the analyzed sample came from a consecrated Host (white, unleavened bread) that had mysteriously turned into bloody human flesh. Amazed by this information, Dr. Zugiba replied, “How and why a consecrated Host would change its character and become living human flesh and blood will remain an inexplicable mystery to science—a mystery totally beyond her competence.”

Only faith in the extraordinary action of a God provides the reasonable answer—faith in a God, who wants to make us aware that He is truly present in the mystery of the Eucharist.

The Eucharistic miracle in Buenos Aires is an extraordinary sign attested to by science. Through it Jesus desires to arouse in us a lively faith in His real presence in the Eucharist. He reminds us that His presence is real, and not symbolic. Only with the eyes of faith do we see Him under appearance of the consecrated bread and wine. We do not see Him with our bodily eyes, since He is present in His glorified humanity. In the Eucharist Jesus sees and loves us and desires to save us.

In collaboration with Ron Tesoriero, Mike Willesee, one of Australia’s best-known journalists (he converted to Catholicism after working on the documents of another Eucharistic miracle) wrote a book entitled Reason to Believe. In it they present documented facts of Eucharistic miracles and other signs calling people to faith in Christ who abides and teaches in the Catholic Church. They have also made a documentary film on the Eucharist—based largely on the scientific discoveries associated with the miraculous Host in Buenos Aires. Their aim was to give a clear presentation of the Catholic Church’s teaching on the subject of the Eucharist. They screened the film in numerous Australian cities. The showing at Adelaide drew a crowd of two thousand viewers. During the commentary and question period that followed a visibly moved man stood up announcing that he was blind. Having learned that this was an exceptional film, he had very much wanted to see it. Just before the screening, he prayed fervently to Jesus for the grace to see the film. At once his sight was restored to him, but only for the thirty-minute duration of the film. Upon its conclusion, he again lost the ability to see. He confirmed this by describing in minute detail certain scenes of the film. It was an incredible event that moved those present to the core of their being.

Through such wondrous signs God calls souls to conversion. If Jesus causes the Host to become visible flesh and blood, a muscle that is responsible for the contraction of a human heart—a heart that suffers like that of someone who has been beaten severely about the chest, if He does such things, it is in order to arouse and quicken our faith in His real presence in the Eucharist. He thus enables us to see that Holy Mass is a re-presentation (i.e. a making present) of the entire drama of our salvation: Christ’s passion, death, and resurrection. Jesus says to his disciples, “Unless you people see signs and wonders, you will not believe” (Jn 4: 48). There is no need to actively seek out wondrous signs. But if Jesus chooses to give them to us, then it behooves us to accept them with meekness and seek to understand what He desires to tell us by them. Thanks to these signs, many people have discovered faith in God—the One God in the Holy Trinity, who reveals His Son to us: Jesus Christ, who abides in the sacraments and teaches us through Holy Scripture and the Magisterium of the Catholic Church.
