FL. 425-430. Latin theologian of Gaul. Probably born in Trier, he was a monk in Marseilles. Cassian spoke of him as a Pelagian, and his christological teaching shows points of contact with Theodore of Mopsuestia* and early Nestorianism.* He issued a letter in which he taught the essential similarity between Christ's moral experience and our own. When rebuked by several bishops of S Gaul, he and his followers fled to Africa, where he met Augustine and publicly recanted his error at Carthage in a Libellus Emendationis which was subscribed by Aurelian of Carthage and Augustine.
