One of Pope Francis' Favorite Eucharistic Miracles occurred in Argentina while he was still archbishop there. It was August of 1996, and a priest in Buenos Aires, Fr. Alejandro Pezet, discovered a host in the back of his church, and so he took it and placed it in some water in the tabernacle to dissolve it. Over the next few days, days he kept an eye on it, and it grew increasingly red. The priest decided to present the case to Archbishop Jorge Bergoglio, who ordered that the host be professionally photographed and eventually examined by a scientist in the U.S., who was not told the origin of the specimen he was testing. The tests showed the sample to be heart muscle with blood type AB, the same blood type found on the Shroud of Turin. The scientist was an atheist and he said, "why did you send me this heart muscle, what was the point of this?" He was told it was a consecrated host, and that atheist scientist converted to Catholicism as a result of that study.
