Guarinus of Sitten was a 12th-century Benedictine monk who served as the Bishop of Sion. Born into a noble family in Pont-à-Mousson around 1065, he entered the Molesme Abbey as a monk in approximately 1085. He later played a central role in establishing Aulps Abbey in Savoy, where he served as the second abbot. His ecclesiastical career culminated in his appointment as bishop in 1138, a position he held until his death in 1150.
Life and work
After joining the Benedictine order, Guarinus helped found Aulps Abbey, a monastery whose name refers to mountain pastures. Following his leadership as an abbot, he was appointed to the bishopric of Sion in 1138. He spent his final years at Aulps Abbey, where he passed away in 1150.
Veneration
Recognized as a saint within the Catholic tradition, he is commemorated annually on August 27. Because of his connection to the mountain regions and his monastic life, he is honored as a patron saint of cattle.
