Throughout Christian history, our Lord has shown us that he is really present as the Blessed Sacrament. Interestingly, many Eucharistic miracles have occurred during times of weakened Faith. For instance, many Eucharist miracles have taken place as a result of someone doubting the Real Presence. Included on this page are descriptions of just a few of these miracles. All of them have received full approval by the Vatican. All of the Eucharistic Miracles are included in the tables below, listed by country of origin.
Most Eucharistic miracles involve incidences in which the Host has “turned into human flesh and blood”. Of course, we as Catholics believe that the consecrated Host is the Body, Blood, Soul, and Divinity of our Lord, under the appearances of bread and wine. Therefore, Jesus, through these miracles, merely manifests His Presence in a more tangible way. See an explanation: What is a Miracle of the Eucharist
