St. Bruno (c. 1030–1101) was a German priest and celebrated theologian who became the founder of the Carthusian Order. Renouncing a prestigious career as chancellor of Reims, he chose a life of silence and prayer. In 1084 Bruno and six companions retreated to the Chartreuse mountains in France, establishing a hermitage that grew into the austere Carthusian monastic order. Renowned for his piety and wisdom, Bruno served briefly as an advisor to Pope Urban II but declined ecclesiastical honors (even turning down a bishopric) to remain faithful to his contemplative calling. Numerous miracles and the casting out of an evil spirit (according to tradition) have been attributed to him, which is why he is invoked against demonic possession. Bruno died in Calabria, Italy, and though never formally canonized via typical process, he was declared a saint by Pope Leo X in 1514. His legacy lives on in the Carthusians’ motto: “Stat crux dum volvitur orbis” – the Cross stands firm while the world turns, exemplifying Bruno’s unwavering faith.
