Two friends of St. Paulinus of Nola introduce this miscellaneous volume. Niceta, a bishop in what is now Yugoslavia, offers five mainly pastoral works, while Sulpicius Severus, from South France, gives us in the Life of St. Martin and in the related Letters and Dialogues the basic story of the ever appealing third bishop of Tours. South France is again the source of the two remaining works here offered, the writings of two contemporaries who in some points took opposing views on the spread of St. Augustine's theology, Vincent opposing some parts of it, Prosper espousing it. Vincent's Commonitories contain the famous threefold test of Catholicity: "what has been believed everywhere, always, and by all."
