Biography
Maternus of Cologne

About Maternus of Cologne
Maternus is the earliest bishop of Cologne known by name. Records place him at the councils of Rome in 313 and Arles in 314, both concerned with the Donatist controversy. At Rome he served as a judge; at Arles he signed the decisions with the Cologne deacon Macrinus. These appearances establish an organized Christian community in Cologne by the early fourth century.
They do not establish whether he was its first bishop or the first whose name survives. Joachim Oepen notes that scholars disagree on this question. Reliable evidence for his origins and other details of his life is lacking. His supposed earlier episcopate at Trier rests on later tradition and is largely rejected by historians; a role in founding the see of Tongeren remains uncertain.
Medieval legends moved him into the apostolic age, making him a companion of Peter’s missionaries. One tells how Peter’s staff restored him to life after forty days in the grave. Such stories express later communities’ claims to apostolic beginnings rather than the chronology established by the council records.
Relics attributed to him were present at Trier by the eighth century, and a burial church there is mentioned in the tenth. No securely documented grave of Maternus is known in Cologne. His name also belongs to a much later Cologne church. Saint Maternus in Neustadt-Süd was consecrated in 1916. Its parish history explicitly identifies the patron as the early Cologne bishop and records the church’s wartime destruction and subsequent rebuilding.
Other dedications include the old riverside chapel and newer church in Rodenkirchen, the chapel at Bechen-Schnappe, and the former chapel at Haus Bürgel. Traditional devotion invokes him against fever and infectious illness, and for flourishing grapevines. These associations describe religious practice, not medical or agricultural guarantees.
Cologne celebrates him on September 11; its account also lists September 14 as his wider commemoration. The Russian Orthodox Church included Maternus in its diocesan Synaxis of the Saints of Germany in 2023. This is observed on October 3 in the civil calendar when that is a Sunday, otherwise on the nearest Sunday.
