Whenever there was a need for food, the cupboard quite bare, Fr. Joseph would pray, place his hands upon what little there was to eat, and what came about was the multiplication of honey, bread, wine and whatever food there was before him.
At other times he simply called upon his Lady to intercede and behold, food miraculously increased.
He would place his cap on a blind man’s head and his sight was restored.
The lame and the crippled walked after they kissed the Crucifix Saint Joseph of Cupertino held out to them.
During the plague which claimed many lives, he blessed a poor soul burning up with fever, making the sign of the Cross on his forehead; the fever immediately dropped, and his temperature returned to normal. With the sign of the Cross, St. Joseph brought the dead back to life.
An arrogant nobleman contemptuously challenged Fr. Joseph:
"Impious hypocrite, it is not you, but the religious habit you wear that I respect and because of it, I trust that if you make the sign of the Cross on my wound, it will heal."
Cheerfully, Saint Joseph of Cupertino humbly agreed with the nobleman that what he said was absolutely true and wise. Then he blessed the nobleman’s wound, whereupon it was completely healed.
