This miracle occurred during Mass in Betania, Venezuela,
on the feast of the Immaculate Conception in 1991. A
Consecrated Host, truly the flesh of Our Lord, began to bleed.
A subsequent medical team concluded that the material
extruded from the Host was blood of human origin.
The local bishop declared it a sign of transubstantiation saying,
"God is trying to manifest to us that our faith in the consecrated
Host is authentic."
