The Miracle of Lanciano
I recently read about the miracle of Lanciano. This miracle had to do with the Eucharist in the small town of Lanciano France around the 700's. During a mass, the Eucharist was being consecrated by a monk who was slowly starting to lose faith in the fact that Christ is truly present, body and blood, in the Eucharist. When the monk spoke the words of consecration the unleavened bread turned into real living flesh, and the wine turned into real blood. The blood the coagulated and formed into 5 separate globs.

This miracle has a very literal connection to the Eucharist. It is a physical symbolization of the bread becoming Christs's flesh, and the wine becoming Christ's blood at consecration. This miracle is the perfect symbol to show what the Eucharist truly is. The Eucharist fully becomes the body and blood of Christ.
