Saint Augustine contra Faustus

Written about the year 400. [Faustus was undoubtedly the acutest, most determined and most unscrupulous opponent of orthodox Christianity in the age of Augustin. The occasion of Augustin's great writing against him was the publication of Faustus' attack on the Old Testament Scriptures, and on the New Testament so far as it was at variance with Manichaean error. Faustus seems to have followed in the footsteps of Adimantus, against whom Augustin had written some years before, but to have gone considerably beyond Adimantus in the recklessness of his statements.
