Arnobius the Younger (Latin: Arnobius Junior) was a Christian priest or bishop in Gaul,[1] who wrote from Rome around the year 460.[2]
He is the author of a mystical and allegorical commentary on the Psalms, first published by Erasmus in 1522, and by him attributed to the elder Arnobius.[1]
It has been frequently reprinted, and in the edition of De la Barre, 1580, is accompanied by some notes on the Gospels by the same author.[1] More recently, CCSL 25 has produced a critical edition of his commentary.[2]
To him has sometimes been ascribed the anonymous treatise, Arnobii catholici et Serapionis conflictus de Deo trino et uno ... de gratiae liberi arbitrii concordia, which was probably written by a follower of Augustine.[1] The opinions expressed in his commentary have been called semi-Pelagian, probably due to his opposition to Augustine's doctrine of predestination.[2] Rondeau infers an African origin for Arnobius due, in part, to his dependence on Ticonius.[2]
