Within a context characterized by the passage from modernity to post-modernity, the author suggests a reflection upon the issue of the theological method. Such a method has recourse to a threefold, hermeneutically related principle: the auditus temporis et alterius, the auditus fidei and the intellectus fidei. The key to this hermeneutic relationship is the search for a formal, fundamental principle that works as a reliable mediation between the Christian revelation and believers. In order to support his thesis, the author uses narrative argumentation accompanied by Luke’s narration of the Emmaus disciples’ episode.
