The Diocese of Pensacola-Tallahassee is inviting worshippers to celebrate the feast day of St. John Cantius.

St. John Cantius was born in 1390 and died on Christmas Eve in 1473, according to Franciscan Media. He was known for being serious, humble, and kind. He lived a spartan lifestyle, only eating and sleeping as much as was necessary, and not keeping any extra money or clothing.

According to Anastpaul.com, St. John Cantius is the patron saint of Poland and Lithuania and his feast day is celebrated on Dec. 23. Cantius.org states that he was also the patron saint of teachers, students, priests and pilgrims.

"Today is the Feast of St. John of Kanty. Greatly revered in his native country of Poland, this saint, also known as John Cantius, spent most of his life teaching at the University of Krakow, where he was a noted professor of sacred Scripture," Diocese of Pensacola-Tallahassee wrote in a Dec. 23 Facebook post. "He also spent an interval as a parish priest, reputedly forced on him because of academic jealousy."

"At the university, he impressed on students the need for moderation and good manners in controversy, and was famous for his boundless generosity to Krakow’s poor. A personal austerity contributed to his reputation for holiness: He ate no meat and slept on the floor. St. John of Kanty, please pray for us!"

Pope John Paul II, who was also Polish, had a special devotion to St. John Cantius, drawing inspiration at the Saint's grave and even praying at the saint’s tomb during his 1997 pilgrimage to Poland.

“[He] belonged to a group of outstanding men, distinguished by knowledge and holiness, who both taught and put into practice, as well as defended, the true faith which was under attack by its enemies,” Pope Clement XIII for St. John Cantius' canonization.
