Celsus was the name of several early Christians:
1. Fifth bishop of Treves, who died, it is said, in 141. His body was discovered in 977, and miracles are reported to have been wrought by it, but his history is uncertain (Acta Sanctorum, Feb. 3, 393).
2. Bishop of Iconium, who allowed a layman named Patulinus to preach, as Demetrius is informed by Alexander (Euseb. H. F. 6:19).
3. A boy, otherwise called Hircitallus, son of the praefect Marcianus and Marcionilla, converted by St. Julian's constancy under his tortures at Antioch, was imprisoned with him, converted his own mother, and was martyred, together with her and seven brethren, on the Feast of the Epiphany-perhaps in A.D. 309.
4. A messenger of Paulinus of Nola to Augustine, who writes by him his eightieth (65th) epistle, in a hurry, as Celsus came late at night to tell Augustine he sailed early in the morning. The date is fixed at A.D. 405.
5. Abbot at the Council of Rouen which gave privileges to the abbey of Fontenelles, A.D. 682.
6. Saint and confessor, of Limoges. Certain relics of this saint are preserved in St. Stephen's cathedral at Limoges, but his history and date are unknown (Acta Sanctorum, Aug. 2, 191).
