He was stuck dead by God for having mocked the intercession of Saint Philomena

In a great city the first feast of St. Philomena was being celebrated with much splendor.  A certain ecclesiastic, seeing the rejoicing and fervor, said contemptuously, "Did we want another Saint here? Have we not feasts enough?"

And murmuring thus, he went home. 

The bystanders were much shocked and began whispering among themselves that the Saint would not leave him unpunished.  The words were scarcely out of their mouths when they beheld his servants running in search of doctors, for he had been struck down by a mortal illness and lay as it dead upon the ground.  He shortly after expired.
