Bonosus of Trier was a 4th-century Catholic bishop who served the diocese of Trier. Following the exile of Bishop Paulinus in 353, Bonosus was chosen to succeed him, but he initially declined the position. He believed Paulinus remained the legitimate leader, an act of integrity that led to his imprisonment by Emperor Constantius II. He eventually accepted the episcopal role only after Paulinus had passed away. During his tenure, he was active in the theological struggle against Arianism.
Life and ministry
After being elected to the bishopric, Bonosus faced imprisonment due to his refusal to replace the exiled Paulinus. He only assumed his duties as bishop later in his life, once the previous leader had died. Throughout his leadership, he worked to defend orthodox Christian beliefs against the spread of Arianism within the region.
Veneration and legacy
The Catholic Church recognizes Bonosus as a saint, with his feast day observed on 17 February. While his remains were once kept at St. Symphorian's Abbey, they are currently located in St. Paulinus' Church in Trier.
