Teacher and Scholar
After completing his studies at the Jagiellonian University in Kraków, John became a professor of philosophy and theology.

Despite his academic success, John lived a life of extraordinary humility. He gave away much of his income to the poor, often keeping only the bare essentials for himself. He treated everyone—students, beggars, and strangers—with kindness and respect. His spirit of charity reflected Christ’s commandment of love and inspired many to seek holiness in their own lives.

John Cantius remained faithful to prayer, penance, and the sacraments. As a confessor, he guided souls with wisdom and compassion, urging them to live in accordance with God’s will. His devotion to the Blessed Virgin Mary and the Eucharist deepened his spiritual strength. Through these devotions, he found the grace to persevere in holiness amid the demands of academic life.
