Nicene and Post-Nicene Fathers: Series I/Volume V/On the Proceedings of Pelagius/Argument
A work on the proceedings of pelagius, 
In One Book,
addressed to bishop aurelius [of carthage], by
written about the commencement of the year, a.d. 417.
The several heads of error which were alleged against Pelagius at the Synod in Palestine, with his answers to each charge, are minutely discussed. Augustin shows that, although Pelagius was acquitted by the synod, there still clave to him the suspicion of heresy; and that the acquittal of the accused by the synod was so contrived, that the heresy itself with which he was charged was unhesitatingly condemned.
