Eucharistic Miracles

Eucharistic Miracle of Buenos Aires


As we celebrate the Solemnity of The Most Holy Body and Blood of Christ (Corpus Christi) this weekend, I'd like to share with you a miraculous event that took place in 1996, which confirms our Catholic teaching about the Real Presence of Jesus in the Holy Eucharist.  Dr. Ricardo Castanon Gomez was an atheist who sought to use scientific research to refute Eucharistic miracles.  Following years of irrefutable evidence in support of these miracles, he became a convert to the Catholic faith.  He now lectures extensively around the world about his work, which provides scientific proof of Christ’s real presence in the Holy Eucharist.  The following is an account of one of his investigations taken from , This is My Body – This is My Blood, offered by Deacon Donald Cox on March 30, 2012.  It is just one of several Eucharistic miracles that have been documented over many centuries.  I hope it will strengthen your faith and commitment to partake in this Sacrament weekly at Mass. 


On August 15, 1996 an elderly Extraordinary Minister of Holy Communion was distributing the Holy Eucharist during Mass at Santa Maria Church in Buenos Aires, Argentina.  Not sure of what to do after having accidently dropped a sacred Host, he asked the priest for assistance.  Our Catholic faith holds that Jesus Christ is truly present – Body, Blood, Soul and Divinity in Holy Communion.  And so, the priest reverently picked up the Host and placed it in a small container of water that is traditionally kept next to the tabernacle for such an event and put the container in the tabernacle where, over time, the Host would be expected to dissolve, at which time it could then be disposed of properly.   Six days later the priest examined the container and was confused to find that the Host had grown in size and was covered with red spots or stains.  He left it in the tabernacle thinking that eventually it would dissolve given sufficient time.  But over a period of several more days, the Host changed in appearance to that of coagulated blood, and eventually looked like a piece of flesh.


A sample of the tissue was sent to a lab in Buenos Aires which reported finding red and white human blood cells and tissue from a human heart.  It also reported that the tissue sample appeared to still be alive because the cells were moving or beating as they would in a live human heart.  Three years later, in 1999, Dr. Gomez was contracted to perform some additional testing.  He sent a sample of the tissue to a lab in New York City.  For the purposes of fair and unbiased testing, the lab was not told what the sample was or anything about its origin.  The lab reported that the sample was living muscle tissue from a human heart.  Five years later, in 2004, Dr. Gomez contacted Dr. Frederick Zugibe and asked him to evaluate a test sample, again without telling him anything about the sample or its origin.  Dr. Zugibe reported that the sample was that of living muscle tissue from a human heart and that it appeared to be taken from a person whose heart had been severely traumatized or beaten.  The doctor was then informed of the fact that the sample was obtained in 1996.  He could not understand how the sample which came from someone supposedly dead could have cells that were still moving and beating.   Needless to say, the doctor was shocked when he was told the whole story.


Then Dr. Gomez arranged to have the lab reports from the Buenos Aires miracle compared to the lab reports from another Eucharistic miracle, the Miracle of Lanciano (700 AD), again without revealing the origin of the test samples.  The experts making the comparison concluded that the two lab reports must have originated from test samples obtained from the same person.  Both samples revealed an “AB” positive blood type and the DNA reports of the two test samples were identical.  One more very important fact is that when the scientific findings of these blood samples were compared to those of the scientific team that analyzed the blood samples taken from the Shroud of Turin and from another Eucharistic miracle, the Sudarium of Oviedo, they were proven to be 100% identical.  They are all an “AB” positive blood type, and characteristic of a man who was born and lived in the Middle East region. 


May these remarkable findings reinforce our faith that what we receive in Holy Communion is not a piece of unleavened bread, but truly Jesus Christ, our Lord and Savior.  Please share this Good News!
