Prodigy of the right hand of the Most High! To accomplish great wonders, He prefers to use abject instruments, sometimes the most unsuitable and despised by men, so that the result cannot be attributed to the creature, but to the Creator alone.

God raised up a poor son of St. Francis, who, gaunt in face, barefoot and destitute, moved half of Europe with his fiery words and led it to triumph under the walls of Belgrade. “Digitus Dei est hic”.
