Gregory of Valencia was born in
Medina del Campo around 1549–50. He received his Bachelor of Arts from the
University of Salamanca, where he undertook the Jesuit novitiate in 1565. In 1567, he went on to study theology at Salamanca, where through his instructor, Mancio, he became interested in the theological renewal movement initiated by Francisco de Vitoria. He studied theology at Valladolid (1568–1571). In 1571, he was called by
St. Francis Borgia, superior general of the Jesuit order, to teach philosophy in
Rome. There he was ordained a priest. He continued his studies at Salamanca (1572). Gregory of Valencia was appointed professor at the University of Dillinguen (1573–1574), and at Ingolstadt (1575–1597), where he taught scholastic theology. He was a member of the
Jesuit College of Ingolstadt while teaching at the
University of Ingolstadt. He then became professor and director of the Jesuit College in Rome (1598) at the request of
Pope Clement VIII. In 1600, he defended the doctrine of the Spanish theologian
Luis de Molina on grace and predestination before the Roman
Curia. He wrote a work in four volumes, covering the whole field of scholastic theology. He held the position of prefect of studies in the
Collegio Romano until, broken in health through incessant work, he died at
Naples on 25 March 1603.
Pope Clement VIII honored him with the title of
