significant point of tension between Roman imperial ideology and Luke's political vision is reflected in Peter's speech to the Roman centurion, Cornelius (Acts 10:36). Peter states that "this one" [οὗτος], i.e. Jesus, "is lord [κύριος] of all." The title, κύριος, was often ascribed to the Roman emperor in antiquity, rendering its use by Luke as an appellation for Jesus an unsubtle challenge to the emperor's authority. Comparison with other writings Gospel of Luke As the second part of the two-part work Luke–Acts, Acts has significant links to the Gospel of Luke. Major turning points in the structure of Acts, for example, find parallels in Luke: the presentation of the child Jesus in the Temple parallels the opening of Acts in the Temple, Jesus's forty days of testing in the wilderness prior to his mission parallel the forty days prior to his Ascension in Acts, the mission of Jesus in Samaria and the Decapolis (the lands of the Samaritans and Gentiles) parallels the missions of the Apostles in Samaria and the Gentile lands, and so on (see Gospel of Luke). These parallels continue through both books. There are also differences between Luke and Acts, amounting at times to outright contradiction. For example, the gospel seems to place the Ascension on Easter Sunday, shortly after the Resurrection, while Acts 1 puts it forty days later. There are similar conflicts over the theology, and while not seriously questioning the single authorship of Luke–Acts, these differences do suggest the need for caution in seeking too much consistency in books written in essence as popular literature. Pauline epistles Acts agrees with Paul's letters on the major outline of Paul's career: he is converted and becomes a Christian missionary and apostle, establishing new churches in Asia Minor and the Aegean and struggling to free Gentile Christians from the Jewish Law. There are also agreements on many incidents, such as Paul's escape from Damascus, where he is lowered down the walls in a basket. But details of these same incidents are frequently contradictory: for example, according to Paul it was a pagan king who was trying to arrest him in Damascus, but according to Luke it was the Jews (2 Corinthians 11:33 and Acts 9:24). Acts speaks of "Christians" and "disciples", but Paul never uses either term, and it is striking that Acts never brings Paul into conflict with the Jerusalem church and places Paul under the
