Founder of the Clerks Regular of St. Paul, commonly known as the Barnabites; b. in Cremona, Italy, 1502; d. 5 July, 1539. While he was still an infant his father died, leaving the care of the child's education to his mother, who taught him compassion for the poor and suffering by making him her almoner. After completing the studies given in the schools at Cremona he was sent to Padua for his philosophy, and in 1520, when he had finished this course, began the study of medicine in the university at that place. At the age of twenty-two he received his degree of Doctor of Medicine and returned to Cremona to practise his profession. Three years later he began to study theology and received holy orders in 1528.
He now devoted himself with renewed energy to works of charity and mercy, visiting and consoling the sick in hospitals and poor-prisons. The ministry of preaching and the administration of the sacraments produced such great fruit that St. Antonio was encouraged to seek a larger field for his labours and to carry out a great project which he hard formed for the good of souls. He went to the populous city of Milan, of which he was a burgess, and entered the Confraternity of Eternal Wisdom. Among the members of this religious body he allied himself with two priests, Fathers Ferrari and Morigia, and told them of his idea of founding a congregation of secular clergy. Northern Italy at this period was in a deplorable condition.
