This work investigates the Lucan journey motif from a literary and theological perspective. It starts by examining the indications of movement in the narrative sequence of the Gospel. Using the historical-critical method, the author continues with a study of the Transfiguration (Luke 9:28-36) and the Ascension (Acts 1:6-11) narratives, and presents a comparison between them. The work concludes with an investigation of the Lucan journey in the two-volume work of Luke. On the literary level, the author suggests that the Transfiguration and the Ascension narratives are composed as an architectural pair and, in turn, serve as the respective starting points for the parallel journeys in Luke-Acts. On the theological level, she shows that the two journeys are, in fact, two stages of the one unique journey, namely the journey of the Salvific Message. Thus, the author provides a further confirmation of the unity of the two-volume work of Luke.
