01
The account begins at Communion
Bishop Zbigniew Kiernikowski’s communiqué dates the event to Christmas Day 2013 at Saint Hyacinth’s church. A consecrated host fell during Communion and was placed in water. A red discoloration later appeared. His predecessor set up a commission to observe the phenomenon; in February 2014 a fragment of the red material was placed on a corporal for examination.
02
What the investigators reported
The bishop quoted a forensic assessment describing fragments of striated muscle whose overall appearance was most similar to heart muscle, and said genetic tests indicated human origin. These are findings reported in a diocesan communiqué; they cannot alone establish how the material got there or a supernatural cause. This site has not independently inspected the samples or the full laboratory records.
03
A decision about veneration
Kiernikowski said he submitted the case to the Congregation for the Doctrine of the Faith in January and, following recommendations of the Holy See, directed the parish to prepare a place for the relic and teach visitors about Eucharistic devotion. The Diocese of Legnica reports that the relic was offered for public veneration on July 2, 2016, with the Holy See’s agreement. The bishop described an event with the hallmarks of a Eucharistic miracle; permission for veneration is not the same as a Vatican declaration of supernatural origin.
