Eusebius' magisterial Praeparatio Evangelica (written sometime between AD 313 and 324) offers an apologetic defence of Christianity in the face of Greek accusations of irrationality and impiety. Though brimming with the quotations of other (often lost) Greek authors, the work is dominated by a clear and sustained argument. Against the tendency to see the Praeparatio as merely an anthology of other sources or a defence of monotheistic religion against paganism, Aaron P. Johnson seeks to appreciate Eusebius' contribution to the discourses of Christian identity by investigating the constructions of ethnic identity (especially Greek) at the heart of his work. Analysis of his `ethnic argumentation' exhibits a method of defending Christianity by construing its opponents as historically rooted nations, whose place in the narrative of world history serves to undermine the legitimacy of their claims to ancient wisdom and piety.
