What happened
On Christmas Day 2013, a consecrated host fell during Communion in Legnica. Following the rubrics, the priest placed it in water to dissolve. Instead, days later, a red stain appeared on it.
The bishop formed a commission and sent samples for blind analysis. After the findings went to Rome, the Congregation for the Doctrine of the Faith concurred, and in 2016 the bishop placed the relic for veneration.
What science found
ContestedTwo independent forensic institutes (Wrocław and Szczecin) reached the same conclusion: fragments of cross-striated muscle "most similar to the heart muscle," with alterations "typical of agony." Human DNA was confirmed; no genetic profile could be obtained.
Where it stands
Diocesan recognition (2016) with the involvement of the Vatican’s Congregation for the Doctrine of the Faith.
Church recognition is a judgment about devotion — not a claim of scientific proof. We keep the two distinct.

The bigger picture
This case is one witness in a much longer story — the Catholic teaching that Christ is truly, substantially present in the Eucharist.
