Memmius of Châlons

Saint Memmius (Menge) is venerated as the first bishop of Châlons-⁠sur-⁠Marne (now Châlons-⁠en-⁠Champagne) and as founder of the diocese. He is a locally venerated saint of the Catholic Church, and his commemoration is on 5 August. The sources place him in the third century.

According to tradition, Memmius was a Roman citizen, consecrated by the holy Apostle Peter and sent to Gaul to preach. According to Flodoard, however, he was a contemporary of Saint Sixtus, bishop of Reims, and so of the third century. He is said to have raised the son of a governor from the dead. His sister, Saint Poma, a virgin and nun, is also venerated as a saint, on 27 June.

Saint Gregory of Tours writes that while travelling through Châlons his servant fell sick with fever. Gregory prayed at the tomb of Memmius and the next morning the servant was cured. Memmius' immediate successors in the see, Donatian and Domitian, are also venerated as saints.

Many churches and two villages bear his name.
