Lorenzo Maria of Saint Francis Xavier – born Lorenzo Salvi – was an Italian Roman Catholic priest and a professed member of the Passionists. Salvi became friends with Gaspar del Bufalo and Bartolomeo Alberto Cappellari – future pope – during the course of his studies prior to his ordination. He was forced out of the Passionist house due to anti-clerical laws from Napoleon Bonaparte but later returned when safe to do so in order to preach and spread the charism of the Child Jesus.
