Celsus of Trier was a legendary bishop of Trier who is said to have died around 141 during the reign of Emperor Antoninus Pius. While his historical existence is considered doubtful by scholars, he is traditionally recognized as the fifth bishop of the diocese. His place in the episcopal lineage was likely established through later legends intended to provide the church in Trier with a more ancient and venerable history.
Life and legend
According to tradition, Celsus served as bishop for fourteen years. Although historical records only confirm bishops in Trier from the late 3rd century, legends place him much earlier. These accounts were part of a broader effort to link the origins of the diocese to the mission of the Apostle Peter and his assistants.
Veneration
Celsus is venerated as a saint, with his feast day observed on February 23. His relics have been housed in various locations, including a basilica rebuilt by Egbert of Trier in 980 and the high altar of St. Paulin. He is also honored in Luxembourg and several churches dedicated to him across Germany, Switzerland, and France.
