I want to study the Eucharistic Miracle that happened in Buenos Aires, 1996. Does someone know if there are some official documents of the Vatican, or another Catholic Church authority?

I just find information in blogs, videos, and other non-official pages.


There is no official Vatican online reference to this alleged miracle, so I did some basic research.

The first thing I noticed is that the details of the 1996 miracle vary according to the source of the story, with at least three variants as to where the host was found. This is typical of urban myths, but by itself that is not enough to disprove the story. The Australian Catholic Weekly, which is not an 'official' source, was asked whether Pope Francis had approved the miracle, and printed an article that says that Francis had investigated the claim before becoming pope. Whether or not Auxiliary Bishop Jorge Bergoglio (now Pope Francis) was impressed with what he was told, it appears that the pope is not moving to have this recognised as a miracle.

This article from Gospa Missions says, "Although this miracle awaits further confirmation in the Church ..." indicating that the Catholic Church has not (yet) accepted the purported miracle.

One source says that Professor John Walker, of Sydney University, had confirmed that the material given to him was human flesh. Sydney University publishes a list of academic staff and, although it reports no Professor John Walker, it appears that a Dr. John Walker had been on the University faculty until 1987, nine years before the supposed miracle, but he worked in medical parasitology. The late Professor Frederick Zugibe is also credited with having tested the specimen and verified that it came from a living heart. This important investigation is not found in any of the biographies that I have found on Zugibe.

A post on the Catholic Answers forum claims the purported miracle to be a fraud, because the Higher Council of the World Health Organization, which supposedly confirmed the findings of Dr. Edoardo Linoli, does not exist.

One could ask why God would perform this obscure miracle in just this way, and the most plausible reason would be either to bring people back to the faith, or to assist the finances of a struggling church in Argentina.

  • Verifying some of those details would make for a good Skeptics question!

    @curiousdannii I have no control over where this question was asked, but I do tend to agree with you. Both answers (including mine) sought unsuccessfully to find the official documents being sought, and both answers provided the results of some online research. I took my research to a second level, to establish how valid the claims are. May 29 '15 at 23:20

I hoped it would be in Joan Carrol Cruz's book Eucharistic Miracles but looks like it is not, probably because it is too modern of a miracle.

However, there is another book called Eucharistic Miracles of the World. I haven't read it but it appears to be published by the Vatican.

I'm not sure how this is legal, but I found excerpts on therealpresence.org.

If you scroll down a bit, there's a section on Argentina and the miracle you reference is there.

The parish of Saint Mary in Buenos Aires has been the protagonist of 3 Eucharistic Miracles that occurred in 1992, 1994 and 1996. Professor Ricardo Castañon Gomez was called by the then Archbishop of Buenos Aires, none other than the current Pope Francis, to analyze the Miracle that occurred on August 15 of 1996.

Sounds pretty cool. Hope it brought a lot of people back into the faith!


This miracle is mentioned in the National Catholic Register:

Then Gomez arranged to compare those lab reports with the ones from the Eucharistic miracle of Lanciano, Italy. That miracle took place during the eighth century. A priest-monk suffered from doubts about Transubstantiation, wondering if the bread and wine really did become the Body and Blood of Christ. He prayed for help believing it was true. At the Consecration of one of his Masses, the Host changed into a circle of flesh, and the wine became blood before the eyes of numerous witnesses. *The Host-turned-flesh and the wine-turned-blood, without the use of any form of preservative, are still present more than 1,300 years later in a reliquary at St. Francis Church in Lanciano. They have been scientifically tested a number of times, with the last one being in 1970.

Again, without revealing the origin of the test samples, the experts compared the Buenos Aires lab reports with those from Lanciano. They concluded that the reports must be from the same samples. Both samples revealed an “AB”-positive blood type, which occurs in 5% of the population. The DNA is identical, and there are features to indicate that the man came from the Middle East. (It is also noteworthy that these lab results match up with those from the Shroud of Turin and the Cloth of Oviedo.)

  • Welcome! Thanks for contributing. I've edited your answer to focus on answering the question itself. If you haven't already done so, I hope you'll take a minute to take the tour and learn how this site is different from others. Jan 30 '17 at 0:51
  • Research on the Turin Shroud has identified DNA from everywhere around the globe, simply proving that people from as far away as China have touched it. No more. So how can the alleged DNA from the eucharist match up with those from the Shroud? Jan 30 '17 at 4:51
