The many scriptural allusions in Luke 1-2 clearly show that the double work of Luke is intended to be understood as a continuation of the "Scriptures" (i.e. the Old Testament). The scriptural quotations referring to Jesus and his fate in this double work, which are almost all spoken by narrative figures, are largely proleptic in Luke 1-23 and mostly analeptic in Luke 24 and the Acts of the Apostles. The crux is the discourse by the resurrected Jesus in Luke 24, which helps Peter in particular come to believe. Scriptural quotations in Luke are also used as both instructions for action and interpretations of the present. Comparison between the use of quotations in narrative texts by other ancient authors (such as the Books of the Maccabees, Josephus, Herodotus, Thucydides and Polybius) illustrates the special nature of the citation style in Luke.
