Nicene and Post-Nicene Fathers, Ser. II, Vol. VI: The Letters of St. Jerome.: Letter CXLI
A short note in which Jerome praises Augustine for the determined stand which he has made against heresy and speaks of him as “the restorer of the ancient faith.” The allusion seems to be to his action in the Pelagian controversy. If so, the date is probably 418 a.d. This letter is among those of Augustine, number 195.
