There was a man in Rimini who refused to believe the doctrine of the Real Presence of Jesus in the Eucharist. St Anthony could not convince the man by his words alone. The man made this deal with St. Anthony: That he would believe if his mule would. The unbelieving man would starve his mule for three days, he would then bring his mule to the town square, Anthony, would bring Jesus in the Blessed Sacrament. If the hungry animal would come to Jesus in the monstrance rather than a bucket of food, then the man would accept the Church’s teachings and believe that Jesus was truly present in the Blessed Sacrament.
On the third day the man came into the town square with his very hungry mule. St. Anthony approached from the other side of the square with the Sacred Host. Many people, both believers and unbelievers alike watched to see what would happen. A large bucket of oats and a bundle of fragrant hay were placed before the hungry animal. But all this was ignored by the mule. Instead, the mule approached our Saint and fell on her knees before the Blessed Sacrament to adore Jesus. True to his word, the man made a profession of faith in the Real Presence because his mule had believed first.
