Although a first reading of Augustine's Commentary suggests that his purpose was simply to expound the meaning of the Letter to the Galatians line by line in a clear and concise manner, closer reading uncovers implicit polemic against Manicheism, Donatism, Arianism, and paganism. Nevertheless, Augustine's Commentary is not essentially polemical, but pastoral. Comparison with his monastic Rule demonstrates that the Commentary was written for Augustine's monastic community as its primary audience and that Augustine's immediate concern was to discover ways in which Paul's directives for Christian living could be implemented within that community. Success within the monastic community would enable Augustine as parish priest to implement Paul's directives within the wider community of his parishioners at Hippo and beyond.
