Chapter 1. Did Christians “Do Dialogue”?
The texts in question are the Jewish Scriptures, and we have here already a dialogue whose argument is based on proof texts and their interpretation. It immediately raises many questions, for instance about the extent, if any, of actual debate between Jews and Christians at Carthage, where there was certainly a Jewish community, and about the nature of Judaism at the time.  It is clear enough that what follows, even at this early date, is a polemic, not a dialogue. It seems, then, as though the birth of Christian literary dialogues in Greek was connected to Christian polemic against Jews and to Christian arguments against heresy.
