Scholarly discussion concerning Elijah in Luke is affected mainly by the detection of the many allusions to Elijah in connection with Jesus and, at the same time, by noting the absence of some associations of Elijah with John the Baptist familiar from the Gospel according to Mark. This twofold observation has brought many scholars to rethink whether or not Luke continues to present John as the Elijah who was to come. In Luke’s perspective, John is the Elijah promised by Malachi acting «in the spirit and power» of the Elijah of old. Luke, furthermore, agrees with Malachi that the promised messenger prepares for «the Lord». These and several other claims concerning the theme are proposed to the reader as the fruit both of the scholarly discussion and of an analysis of the appropriate Lucan texts in this monograph.
