The Catholic Church teaches a dogma called “transubstantiation,” which the Catechism explains thus: “By the consecration of the bread and wine there takes place a change of the whole substance of the bread into the substance of the body of Christ our Lord and of the whole substance of the wine into the substance of his blood” (CCC 1376).
This means that while the appearances of bread and wine remain, the substance is changed (through the power of God) completely to the body and blood of Christ. It is a teaching based on scripture and tradition and has remained unchanged in its essence since Apostolic times.
However, the Church has recognized that on occasion, God intervenes in a more visible way and can change even the appearances of the bread and wine into his body and blood. Even though the Church does not base her teaching on these miracles, but on Christ’s word, when God chooses to do such miracles there is usually a flowering of belief in the Eucharistic Presence of Jesus Christ.
Here are four of the most incredible Eucharistic miracles that have been examined by top scientists around the world, who ultimately concluded that science could not explain the miraculous phenomenon.
