The photograph above was taken during the Divine Liturgy in the Sacred Church of the Holy Trinity, at the village of Stavrodromi in Kerkini of Northern Serres on the Second Sunday of Matthew on May 24(O.S.)/June 6(N.S.), 2010.
It depicts an unexplained wonder on the Holy Diskarion, which is the golden dish the bread of the Eucharist is placed on before inserted into the Holy Chalice. This Holy Diskarion was brand new and never used before this Divine Liturgy, but after the Epiklesis prayer when the Priest supplicates God to transform the Bread and Wine into the Body and Blood of Christ, the burn mark appeared.
The burn mark indicates that tremendous heat came in contact with the Holy Diskarion from the Holy Bread as it changed into the Divine Body of Christ. This took place without any damage or burning of the Holy Gifts that were on the Holy Diskarion at the time. This is highly unusual, since the seal of the Holy Bread with the fragments can be clearly seen.
This wonder reminds one of the Unburnt Bush mentioned in the Old Testament.
St. Symeon of Thessaloniki (+ 1429) teaches that the entire Militant and Triumphant Church with Christ as its Head is represented on the Holy Diskarion when the Holy Gifts are changed into the Body of Christ during the time of the Epiklesis.
