Belgium · 14th Century
In 1317, thieves broke into the Cistercian convent church of Herkenrode near Hasselt, Belgium, and stole a ciborium containing consecrated Hosts. Seeking only the valuable silver container, the sacrilegious thieves threw the Hosts into the Demer River. Several days later, local residents noticed a mysterious bright light hovering over the water. When they investigated, they discovered the consecrated Hosts floating on the surface of the river, surrounded by an otherworldly glow and in perfect condition despite having been submerged in the water. The Hosts showed no signs of decomposition or water damage. The parish priest was immediately summoned, and the Hosts were recovered with great reverence. They were brought back to the church in solemn procession, with the entire community participating. The miracle was investigated and confirmed by the Bishop of Liège. A chapel was later built near the site where the Hosts were found to commemorate the miracle. The event strengthened Eucharistic devotion throughout the region and served as a powerful reminder of God's protection of the Blessed Sacrament, even when subjected to desecration. The Hosts' preservation in water mirrors biblical accounts of divine protection and demonstrates that Christ's presence in the Eucharist cannot be destroyed by human malice.
Multiple tests were conducted over the centuries to verify the miraculous preservation of the Host. Notable examinations include one in the 18th century by Apostolic Nuncio Carafa and the Bishop of Liège, and another by the Archbishop of Malines during a visit by Archduchess Isabel.
