Saint Giovanni Leonardi

John Leonardi, OMD (Italian: Giovanni; 1541 – 9 October 1609) was an Italian Catholic priest and the founder of the Clerics Regular of the Mother of God of Lucca. He was the youngest of seven children born to middle-class parents in Diecimo (now within the comune of Borgo a Mozzano) in the Republic of Lucca. From childhood, he sought solitude and wished to dedicate himself to prayer and meditation. At age 17, he began his ten-year study to become a certified pharmacist's assistant in Lucca. Afterward, he studied for the priesthood and was ordained in 1572, as a member of the now defunct Apostolic Clerics of St. Jerome. He first dedicated himself to the Christian formation of adolescents in his local Lucca parish. He also gathered a group of laymen around him to work in hospitals and prisons. In 1574, he founded a group charged with deepening Christian faith and devotion; this foundation was part of the wider movement of the Counter-Reformation. Leonardi worked with this group to spread devotion to the Blessed Virgin Mary and devotion to the Forty Hours, as well as spreading the message of the importance of frequent communion. He became interested in the reforms instituted by the Council of Trent, and he proposed a new congregation of secular priests to convert sinners and to restore Church discipline. In 1583, his association, which became known as the Lucca Fathers, was recognized by the Bishop of Lucca with the approval of Pope Gregory XIII. In 1595, his congregation was confirmed by Pope Clement VIII, and he assumed the religious name "Giovanni of the Mother of God". This foundation received approval from Pope Paul V on January 14, 1614. The pope, encouraged by the cardinal protector Giustiniani issued a papal decree approving the union of the Lucca Fathers with the Piarists of Saint Joseph Calasanz. This union would last only until the beginning of 1617 when Paul V issued another decree constituting the Piarists as a separate congregation.
