The goal of this redaction-critical investigation is to determine what in Luke 22 is special to Luke, to assess its origin, and to uncover Luke's purpose in using this material. Unlike earlier studies, Soards concentrates on lines of thought that link the chapter with the Gospel as a whole. The author's conclusion is that though Luke did not use a single coherent source other than Mark for this chapter, his diverse material was chosen in order to advance Luke's distinctive interests in Christology, eschatology and ecclesiology. Christologically, Jesus is shown as in charge of the Passion events and as the realization of a divine plan; eschatologically, the Passion is portrayed as inaugurating the era of the Last Days; ecclesiologically, Jesus's attitude to his disciples functions as instruction for Luke's readers about their role in God's plan.
