Robert F. O'Toole, «How Does Luke Portray Jesus as Servant of YHWH», Vol. 81 (2000) 328-346
This article explains Luke's meaning of Jesus as Servant of YHWH and claims this title as part of Luke's christology. Many references to Jesus as Servant of YHWH are unique to Luke, and a few summarize Jesus' ministry. These summary passages particularly look to Jesus' saving activity, universal mission and suffering. Other Servant of YHWH passages point out that Jesus is specially chosen and pleasing to God and determined to do his will. In particular, Acts 8,32-33 summarize Jesus' passion during which Luke views Jesus as the Servant and thus humble, innocent and silent. As the Servant Jesus is also risen and active.
and can function as a summary of Jesus mission. He is Gods chosen one. The Servant Tradition particularly served Luke to explain Jesus suffering and passion and to underline his innocence. Moreover, the theme of Jesus as Servant of YHWH expands Lukan salvation with special reference to the image of light and justifies Jesus mission to the Gentiles.
