How do I know that Jesus Christ is God??? Um, He rose from the dead???? He worked miracles??????? He has appeared to people throughout the ages??????? Isn't that enough????? And how do you explain the Eucharistic miracle in the 8th century in Italy?????? A priest doubted that the bread and wine was actually the Body and Blood of Jesus, because, even after the Consecration, the Body and Blood remain the same in appearance and taste. While he was saying Mass one day, during the Consecration, the bread changed into the actual Flesh, and the wine, into the actual Blood. If you don't believe me, go to Lanciano, Italy. In the very center of the city is the church in which the Living Flesh and Blood of Our Lord's Sacred Heart has rested since the eighth century. Analyses have been conducted with absolute and unquestionable scientific precision, and they were documented with a series of microscopic photographs which were rendered a matter of public domain by the esteembed Professor Linoli himself in a conference held March 4, 1971 in the church of the Miracle. The analyes sustained the following conclusions: 1) the Flesh is real Flesh. The Blood is real Blood. The Flesh consists of the muscular tissue of the heart (myocardium). 2) Thee Flesh and the Blood belong to human species. 3) The Flesh and the Blood have the same blood-type (AB). 4) In the Blood there were found proteins in the same normal proportions (percentage-wise) as are found in the sero-proteic make-up of fresh normal blood.  5) In the Blood there were also found these minerals: chlorides, phosphorus, magnesium, potassium, sodium and calcium. 6) the preservation of the Flesh and Blood, which were left in their natural state for twelve centuries (i.e. without any chemical preservatives) and exposed to the action of atmospheric and biological agents, remains an extraordinary phenomenon.
