St. John Cantius (1390-1473)
John was a highly educated priest and the chair of theology at the Academy of Krakow, Poland. He made one pilgrimage to Jerusalem and four to Rome on foot. Admired for his humility and charity and the practice of mortification, many miracles are attributed to him.

Reflections from the Saints

Fight all error, but do it with good humor, patience, kindness, and love. Harshness will damage your own soul and spoil the best cause.
– St. John Cantius
