Eucharistic miracle

In Christianity, a Eucharistic miracle is any miracle involving the Eucharist. The Roman Catholic, Lutheran, Eastern Orthodox, Methodist, Anglican and Oriental Orthodox Churches believe that Christ is really made manifest in the Eucharist and deem this a Eucharistic miracle;[1][2] however, this is to be distinguished from other manifestations of God. The Catholic Church distinguishes between divine revelation, such as the Eucharist, and private revelation, such as Eucharistic miracles. In general, reported Eucharistic miracles usually consist of unexplainable phenomena such as consecrated Hosts visibly transforming into myocardium tissue, being preserved for extremely long stretches of time, surviving being thrown into fire, bleeding, or even sustaining people for decades.

Sacrarium of the Eucharistic miracle of Lanciano; it is maintained that the upper portion contains the heart tissue, while the lower receptacle contains the pellets of clotted blood.
Verification of Eucharistic miracles often depends on the religious branch reporting the supposed miracle, but in the case of the Catholic Church, a special task-force[3] or commission investigates supposed Eucharistic miracles before deciding whether they are "worthy of belief." As with other private revelations, such as Marian apparitions, belief in approved miracles is not mandated by the Catholic Church, but often serves to reassure believers of God's presence or as the means to "send a message" to the population at large. Anglican Churches have also reported extraordinary Eucharistic miracles.
