On many occassion throughout the history of the Catholic Church, God has provided visible proof of the invisible reality of the Real Presence of Jesus Christ in the Holy Eucharist. In her book, Eucharistic Miracles, Joan Carroll Cruz documents 36 such major miracles which occurred throughout history. She tells of consecrated Hosts which have turned to visible human flesh, which have bled, which have levitated, and which have become hard as flint when received by a person in mortal sin. She details the official investigations that ahve been made into these miracles, and tells readers where some can still be seen and venerated today. The author also describes miraculous Eucharistic phenomena in the lives of the Saints: Saints who lived on the Eucharist alone, who received Communion miraculously or experienced raptures, ecstasies, levitations, visions, locutions, and other extraordinary phenomena.
