From Satanist Priest to Warrior for Christ: St. Bartolo Longo

St. Bartolo Longo transitioned from a practitioner of the occult to a canonized saint after a period of spiritual crisis. Born in 1841 to a devout Catholic family in Latiano, Italy, Longo began to doubt the Real Presence of the Lord following the death of his mother.

According to Catholic Exchange, Longo's doubts grew during his university years due to the secular views of his professors and peers, as well as the political upheaval in Italy. These influences led him toward spiritualism and the occult, eventually resulting in his involvement with a cult.
