Throughout its history the Catholic Church has documented and approved a number of Eucharistic miracles. These recorded incidents of consecrated hosts turning into human flesh and blood are said to have occurred mainly at moments of serious doubt about the Real Presence. It was a Eucharistic miracle (in 1263, Bolsena, Italy) that is believed to have prompted Pope Urban IV to institute the feast of Corpus Christi.
The Catechism teaches: “In the most Blessed Sacrament of the Eucharist ‘the body and blood, together with the soul and divinity, of our Lord Jesus Christ and, therefore, the whole Christ, is truly, really, and substantially contained.'”
If even in Our Lord’s day the crowds walked away with mutterings of “intolerable language” after hearing Jesus speak of His flesh and blood as necessary sustenance for our immortal souls, it is hardly surprising that through the ages Christian hearts have been troubled by doubt, distortion and dissent regarding this doctrine.
While Catholics are not bound to believe in Eucharistic miracles (though they must accept the possibility of such divine intervention), their accounts have surely opened many a doubting Thomas up to the gift of faith in the Real Presence. It is a gift the believer should never take for granted, for when we adore and receive the sacred Body and Blood of Jesus, we partake of the greatest treasure that God has to offer us through His Catholic Church.
“Then he said to Thomas, ‘Put your finger here, and see my hands; and put out your hand, and place it in my side; do not be faithless, but believing.’ Thomas answered him, ‘My Lord and my God!’ Jesus said to him, ‘Have you believed because you have seen me? Blessed are those who have not seen and yet believe.'” (Jn 20:27-29)
