Catulinus is the name of several persons in early Christian history:
1. (Also Catullinus) The subdeacon at Cirta, under Paul the bishop, A.D. 303. On May 19, in that year, after the church furniture had been given up, he was called upon to surrender the books, but only produced one very large volume, as the readers had the rest. When asked the readers names, both he and Marcucius refused to answer. Though "traditors," they would not be "traitors" (proditores). They were arrested; but we do not hear of the end of Catulinus's imprisonment.
2. The deacon, martyr at Carthage, buried in the basilica of Faustus in that city; commemorated July 15, and honored with a sermon by Augustine (according to Possidius), which is no longer extant (Tillemont, 5, 554).
3. The sixths bishop of Embrun (Ebredunum). He subscribed at the Council of Epaune (Epaunum, Epavnum), which was held in 517, when Sigismund was king of Burgundy and Hormisdas pope. While executing the decrees of this synod in his city he was ejected by the Arians, and took up his residence at Vienne, with Avitus the bishop. He passed years of exile devoted to good works (Gall. Christ. 3, 1060).
