Before delving into the text of The City of God, Professor Mathewes sets the stage with some context about the many audiences that Augustine was writing for, as well as the arguments against Christians that he was confronting. See how Augustine co-opted Roman notions of city" and "glory" and applied them to his divine purpose."
A fascinating lecture about the word City of the title and the first word of the book with a tad about the rest of the first sentence!
