St Augustine devotes a work of twenty-two books to the defense of the city of God, and in his other writings he often assumes his readers to be familiar with this heavenly city of which they are members. It is consequently surprising that scholars have found his account of it ambiguous and that they have been so little able to reach agreement as to just what the city of God is.
Some of their difficulties have resulted from trying to answer questions which Augustine had not considered and which, indeed, he could not consider in his own terminology. We must not, for example, expect to find in his writings a solution to the problem of ‘church’ and ‘state,’ for this is a modern question and its terms are incommensurable with those of the fifth century. Our account of the city of God must be placed in an Augustinian context, and our analysis should ultimately admit translation into Augustinian Latin.
