<P> 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, immediately after the Resurrection, while Acts 1 puts it forty days later . There are similar conflicts over the theology . 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 . </P> <P> Acts agrees with Paul's letters on the major outline of Paul's career: as Saul he is converted and becomes Paul the 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 seen as 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 authority of the Jerusalem church and its leaders, especially James and Peter (Acts 15 vs. Galatians 2). Acts omits much from the letters, notably Paul's problems with his congregations (internal difficulties are said to be the fault of the Jews instead), and his apparent final rejection by the church leaders in Jerusalem (Acts has Paul and Barnabas deliver an offering that is accepted, a trip that has no mention in the letters). There are also alleged major differences between Acts and Paul on Christology (the understanding of Christ's nature), eschatology (understanding of the "last things"), and apostleship . </P>
