This article, for the first time, analyses one of Augustine’s sermons in order to
find out to what extent he was acquainted with Mani and his teachings. Once
again, it turns out that the former Manichaean auditor was very well acquainted
with Manichaean belief and practice. One piece of data in sermo 182, namely
that Manicheans could make polemical use of the expression Libera nos a malo
in the Lord’s Prayer, even seems to be unique.
