The anti-Donatistic works, composed between the years 393 and 420, argue against separatism, and contain Augustin's doctrine of the church and church-discipline, and of the sacraments. To these belong: Psalmus contra partem Donati (A.D. 393), a polemic popular song without regular metre, intended to offset the songs of the Donatists; Contra epistolam Parmeniani, written in 400 against the Carthaginian bishop of the Donatists, the successor of Donatus; De baptismo contra Donastistas, in favor of the validity of heretical baptism (400); Contra literas Petiliani (about 400), against the view of Cyprian and the Donatists, that the efficacy of the sacraments depends on the personal worthiness and the ecclesiastical status of the officiating priest; Ad Catholicos Epistola contra Donatistas, or De unitate ecclesiae (402); Contra Cresconium grammaticum Donastistam (406); Breviculus Collationis cum Donatistis, a short account of the three days' religious conference with the Donatists (411); De correctione Donatistarum (417); Contra Gaudentium, Donat. Episcopum, the last anti-Donatistic work (420). ¹

These works are the chief patristic authority of the Roman Catholic doctrine of the church and against the sects. They are thoroughly Romanizing in spirit and aim, and least satisfactory to Protestant readers. Augustin defended in his later years even the principle of forcible coërcion and persecution against heretics and schismatics by a false exegesis of the words in the parable "Compel them to come in" (Luke xiv. 23). The result of persecution was that both Catholics and Donatists in North Africa were overwhelmed in ruin first by the barbarous Vandals, who were Arian heretics, and afterwards by the Mohammedan conquerors.
