In St. Hyacinth’s church in Legnica, during Holy Mass, on December 25, 2013, a Host accidentally fell on the ground, during the distribution of Communion. It was immediately placed in a container with water and closed in the tabernacle.
St. Hyacinth’s priest, Father Andrzej Ziombra, said that on January 4th, along with other priests, he went to see if the consecrated Host had dissolved in the water after nearly two weeks: "Immediately we noticed that the Host had not dissolved, and that a red spot covering a fifth of Its surface appeared. We decided to inform the Bishop, who established a special theological scientific commission to analyze the event.
We noticed that over time the stain on the Host changed color from deep red to red brown (...). The sample was taken directly by the scientists on 26 January 2014.
For the priests the miracle was evident. The commission checked if It was some fungus, mold or another external agent (...). The Wroclaw Forensic Medicine Institute immediately excluded the presence of bacteria or fungi as a cause for the Host turning red.
A second histopathological analysis pointed out that some fragments seemed to belong to myocardial tissue. An additional opinion was sought using the same samples at the Institute of Forensic Medicine in Szczecin without specifying where the samples came from. The Institute used a different analysis method.
After the analysis, The Pomeranian Medical University’s Department of Histopathology in Szczecin announced that “tissue fragments containing fragmented parts of cross-striated muscle” was found in the histopathological image. This is similar to “human heart muscle with alterations that often appear during the agony. We have not tested the blood found on the Host, we only know that human DNA was found.”
