St. Anthony of Padua, the thirteenth century doctor of the Church, stated that when it comes to teaching the Catholic faith, “Actions speak louder than words.” St. Anthony was especially aware of the importance of the act of kneeling before the Blessed Sacrament when teaching the doctrine of the Real Presence because God endorsed this act of adoration by means of a miracle, which St. Anthony and others witnessed.
Martin Herbert recalls this miracle in a special 1994 Eucharistic Adoration issue of the Immaculata published by the Franciscan Friars of Marytown in Kenosha Wisconsin. Martin Herbert tells the story as follows:
A certain heretic by the name of Bononillo was unmoved by the persuasive reasoning of the Saint (Anthony). He was as stubborn as the mule standing beside him in denying the Real Presence. Eyeing the mule, Anthony made an offer to Bononillo. He asked him whether he would give up his heresy if the mule were to bow down and adore its Creator present in the Blessed Sacrament. The heretic answered he would, provided he could lay down certain conditions: for two days the mule was not to be fed, and on the third day it was to be led into the public square. On one side of the square would be placed a tempting pile of fresh feed, on the opposite side Anthony could stand with what Bononillo contemptuously called the “body of Christ.” Anthony agreed, but in all humility made one condition. If the animal did not kneel before the Blessed Sacrament, his sins alone were to be blamed. The day arrived for this strange contest and the square was crowded with people. When the derisive Bononillo arrived with his half-starved mule, he was fully confident that his mule had sense and appetite enough to go after the feed. However, he was wrong. Anthony had implored his Lord in the intervening two days for the soul of this heretic. God did not let his faithful servant down. When turned loose, the mule without the least hesitation advanced toward Anthony and knelt in an attitude of adoration before the Blessed Sacrament. With much emotion and contrition, the heretic too fell on his knees and gave up his heresy.
