As Catholics, we believe in the Real Presence, whereby Jesus Christ is made literally present in a consecrated Host through transubstantiation.
“Jesus said to them, ‘Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life within you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise him on the last day.'” – John 6:53-54
Since its earliest inception, many have been intensely skeptical of the Catholic doctrine of the Real Presence. However, over the centuries there have been many reports and accounts of the Host miraculously turning into physical flesh and blood. When studies were performed on these miraculous Hosts, along with relics of Christ, an astonishing discovery was made – the same blood type was found every time – type AB.
The earliest recorded event of a consecrated Host miraculously turning into physical flesh and blood dates back to the 8th century in the city of Lanciano, Italy. Called the Miracle of Lanciano, a monk was skeptical about the Real Presence and transubstantiation. When he celebrated Mass and said the Words of Consecration with doubt in his soul and heart, before the monks eyes he saw the the Host changed into living flesh and the wine change into coagulated blood.
In 1971, scientists performed a study on these relics which had been perfectly preserved throughout the ages. The Host was human heart tissue with the blood type AB, the rarest of all. The blood was found to have no preservatives, and also was blood type AB.
Another miraculous occurrence took place in 1996, when a women in Buenos Aires found a desecrated Host in a candle holder in her parish church. She turned the Host into her priest who went to dissolve it into water per Canon Law. When the priest went to do so, the Host turned into flesh and blood. 3 years later, the Bishop of Buenos Aires sent the host to the US for testing. The results came back the same – human heart tissue with blood type AB. At the time, the Bishop of Buenos Aires was Jorge Bergoglio – Pope Francis.
Additional tests of trace amounts of blood on the Shroud of Turin along with traces from the Shroud of Oviedo (the cloth wrapped around Christs face shortly after his death) also were shown to be of blood type AB, lending credence to the evidence that Christs blood type was AB, and Hosts literally turn into His flesh and blood when consecrated.
Amazing coincidence or proof? Blood type AB is the universal recipient for blood transfusions, and all tested Hosts were found to be heart tissue. As we know, Christ will receive anyone into His heart who is willing.
