On December 25th, 2013, a Host fell on the floor during communion at the Święty Jacek Church in Leginca Poland. Per normal procedure, the host was picked up the host and placed into a container of water to dissolve. Two weeks later, Father Andrzej Ziombra opened the tabernacle to check and see if it had fully dissolved yet. He stated:
"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.
The Host was sent to the Department of Forensic Medicine at Wroclaw who presented the following after investigation:
In the histopathological image, the fragments of tissue have been found containing the fragmented parts of the cross striated muscle. (...) The whole (...) is most similar to the heart muscle with alterations that often appear during the agony. The genetic researches indicate the human origin of the tissue.
The Bishop of Legnica further wrote:
In January this year I presented the whole matter to the Congregation for the Doctrine of the Faith in the Vatican. Today, according to the recommendations of the Holy See, I ordered the parish vicar Andrzej Ziombro to prepare a suitable place for a display of the Relic so that the faithful could give it the proper adoration. Hereby, I also ask for providing the visitors with information and conducting the regular teaching that could help the faithful to have the proper attitude to the eucharistic cult. I also command to form a book to register all received benefits and other miraculous events. I hope that this will serve to deepen the cult of the Eucharist and will have deep impact on the lives of people facing the Relic. We see the misterious Sign as an extraordinary act of love and goodness of God, who comes to humans in ultimate humiliation.
