The Treatise on the Miracles of Saint Francis - 404 

Let there be no room for ambiguity:
let no one doubt this outpouring of everlasting goodness!
If only the many members were joined
in that same seraphic love to Christ their head!
If only they were to be found worthy of such armor in a similar
and be raised to the same rank in the Kingdom!
Who of sane mind would not attribute this to the glory of Christ?
But let the punishments already inflicted on unbelievers repay the
and make the reverent even more confident.

6In Potenza, a city in the kingdom of Apulia, there was a cleric named Ruggero, an honorable man and a canon of its major church. He was weakened by a long illness, and one day he entered a church to pray for his health. In the church there was a painted image of blessed Francis, showing the glorious stigmata. He approached, knelt down before the image and prayed with sincere devotion. However, as he fixed his eyes on the saint's stigmata, he turned his thoughts to useless things, and did not repel by force of reason the creeping sting of doubt. With the old enemy deceiving him, his heart torn, he began to say to himself: "Could this be true, that this saint could be singled out for such a miracle, or was this a pious fraud of his followers? Was this," he asked, "a sham discovery, perhaps a deception invented by the brothers? This goes beyond common sense, and is far from reasonable judgment."

The madness of the man! Fool! You should rather have humbly venerated that divine work all the more, the less you could comprehend it. You should have known, if your reason was working, that it is the easiest thing for God to renew the world always with new miracles, always to work in us 1 Cor 4:12 for His glory things He has not done in others.

What happened? A severe wound was inflicted by God on the one thinking empty thoughts, so that he might learn from the things he suffers not to blaspheme. He was instantly struck in the palm of his left hand (he was left-handed) as he heard a noise like an arrow shot from a bow. Instantly, as he was injured by the wound and stunned by the noise, he took off the glove from his hand, since he was wearing gloves. Though there had previously been no mark in his palm, he now saw a wound in mid-hand, as if struck by an arrow. So much heat was coming from it that he thought he would pass out. What a wonder! There was no mark on the glove, so the pain of the hidden wound corresponded to the hidden wound of his heart.
