Bonosus of Trier

Holy Hierarch Bonosus of Trier was bishop of Trier in the 4th century, between about 353 and 373. After Bishop Paulinus of Trier was exiled to Phrygia in 353, an episcopal election was held and Bonosus was elected, but he refused, being convinced that Paulinus remained the rightful bishop of the city. The Emperor Constantius II was so angry that he had him thrown into prison.

Only after the death of Paulinus, in 358 (or at the latest in 361, after the emperor's death), did Bonosus take the see. He labored against Arianism. His tomb was for a time at the abbey of Saint Symphorian in Trier, and today is in the church of Saint Paulinus. In the diocese of Trier he is venerated as a saint and commemorated on 17 February, by the Western calendar (new style). He is a saint of the undivided Church.
