This Eucharistic miracle goes back to 1374. In St. Peter’s Church in Middleburg, during Holy Communion the consecrated Host changed into bleeding Flesh. A portion of the Host to this day is kept in Louvain by the Augustinian Fathers. The monk, Jean de Gheest, confessor of the Archbishop who approved the cult, asked for the Precious Relic as a gift. The other portion is in St. Peter’s Church in Middleburg. here exists much documentation on the Eucharistic miracle.
In a monograph written in 1905 by historian Joseph Wils, professor of the Catholic University of Louvain, entitled Le Sacrement du Miracle de Louvain, are cited almost all the contemporary documents and testimonies.
In Middleburg lived a noble woman known by everybody for her great faith and devotion. The woman was also very attentive to the spiritual formation of her family and household staff. During the Lent of 1374, as she did every year in her house, she began to do penance in preparation for the coming of Easter.
A few days before, a new manservant by the name of Jan was hired, who had not gone to confession for many years, in spite of the dissolute life he was living. The woman invited all the household staff to go to Mass. Jan did not dare oppose this invitation so as not to disappoint her.
He attended the whole Eucharistic celebration, and when it was time to receive Holy Communion, the man approached the altar with much superficiality. As soon as he received the Host on his tongue, the Sacrament changed into bleeding Flesh. At once Jan took the Particle from his mouth; Blood dripped from the Sacred Flesh onto the cloth covering the altar rail. The priest realized at once what was happening, and with great emotion, carefully placed the miraculous Particle in a vessel inside the tabernacle.
Jan repented and confessed his sin before everyone. From that day on, he led an exemplary life and nourished a great devotion to the Most Blessed Sacrament to the end of his life. All the church and civil authorities of the city were informed of the miraculous event and after diligent investigation the Archbishop authorized the cult of this miraculous event.
Prayer of St. Ambose:
Most Sweet Bread, heal my heart, that I may taste the sweetness of Your love. Heal it from all weakness, that I may enjoy no sweetness but You. Most pure Bread, containing every delight which ever refreshes us, may my heart consume You and may my soul be filled with Your sweetness. Holy Bread, living Bread, perfect Bread, that has come down from heaven to give life to the world, come into my heart and cleanse me from every stain of body and soul. Enter into my soul; heal and cleanse me completely. Be the constant safeguard and salvation of my soul and body. Guard me from the enemies who lie in wait. May they flee from the protecting presence of Your power, so that, armed in soul and body by You, I may safely reach Your Kingdom. There we shall see You, not as now as in mysteries, but face to face, when You will deliver the Kingdom to God the Father, and will reign as God over all. Then You, who with the same God the Father and the Holy Spirit, live and reign forever, will satisfy the hunger of my soul perfectly with Yourself, so that I shall neither hunger nor thirst again. Amen.
