Book excerpt: Despite the striking frequency with which the Greek word kyrios, Lord, occurs in Luke's Gospel, this study is the first comprehensive analysis of Luke's use of this word. The analysis follows the use of kyrios in the Gospel from beginning to end in order to trace narratively the complex and deliberate development of Jesus' identity as Lord. Detailed attention to Luke's narrative artistry and his use of Mark demonstrates that Luke has a nuanced and sophisticated christology centered on Jesus' identity as Lord.
