In 1429, in Alkmaar’s Cathedral of Saint Lawrence, a priest named Folkert was celebrating his first Mass. After the consecration, the priest accidentally knocked over the chalice, spilling consecrated wine on the altar and on his chasuble. The wine was miraculously transformed into Blood. Every attempt to remove the traces of Blood from the chasuble was in vain. The precious reliquary of the chasuble soaked in Blood is preserved even today in the Cathedral of Saint Lawrence in Alkmaar.
In the Cathedral of Saint Lawrence in Alkmaar, there is a precious reliquary shaped like an angel that contains the chasuble soaked in blood from the Eucharistic miracle that happened in 1429.
