St. Anthony Zaccaria, born on December 15, 1502, in Cremona, Italy, was a Catholic priest and the founder of the Barnabites, a religious order dedicated to the education and spiritual formation of youth. He studied at the University of Padua, where he received his doctorate in theology, and became known for his deep piety and commitment to reforming the Church during the Counter-Reformation.

In 1530, he established the Oratory of St. Paul, aiming to revitalize faith through prayer and communal study. Zaccaria emphasized the importance of both contemplative and active life, encouraging his followers to engage with the world while remaining devoted to God. His innovative approach combined pastoral care with a strong emphasis on education.

St. Anthony Zaccaria died on July 5, 1539, at the age of 36. He was canonized by Pope Leo XIII in 1897. His feast day is celebrated on July 5, and he is revered as a patron saint of the Barnabites and of catechists, reflecting his lifelong dedication to teaching and spiritual guidance.
