The single type of writing that Luke's Preface resembles most is the Greek decree. Along with other indications, the structure situates Luke in the tradition of Classical historiography. It also creates important links to the narrative, helping to define: the relationships between Roman power and Christianity and between Classical and Lukan historiography; the character of the Christian politeia; the superiority of Lukan historiography both to Classical and to previous Christian historiography; the superiority of Lukan Christian doctrine; and the superiority of the ‘reward’ from Luke's Christian ‘contract’ to the ‘rewards’ of the Classical historians Thucydides, Livy and Augustus and to those of the Roman politeia.
