Officials are investigating, according to this report:
The mystery centers on a consecrated host that the Rev. John Echert of St. Augustine Church said fell to the floor last month during Holy Communion and turned “blood red” after being placed in a cup filled with water. It has yet to fully dissolve, he said.The archdiocese, which now has the host, is taking a “very cautious stance on the matter,” spokesman Dennis McGrath said.
“I make no claims, and the archdiocese makes no claims, as to the likelihood of this being supernatural,” Echert said. “But it is enough of a phenomenon, or unusual, that we will continue to examine this host.”
He added: “I’ve never in my 24 years as a priest seen or been aware of a phenomenon where a consecrated host placed in water turns to this bright-colored red and continues in what I would call the blood-red color.”
