preach his message to all nations, "beginning from Jerusalem." He repeats the command in Acts, telling them to preach "in Jerusalem, in all Judea and Samaria, and to the end of the Earth." They then proceed to do so, in the order outlined: first Jerusalem, then Judea and Samaria, then the entire (Roman) world. For Luke, the Holy Spirit is the driving force behind the spread of the Christian message, and he places more emphasis on it than do any of the other evangelists. The Spirit is "poured out" at Pentecost on the first Samaritan and Gentile believers and on disciples who had been baptised only by John the Baptist, each time as a sign of God's approval. The Holy Spirit represents God's power (at his ascension, Jesus tells his followers, "You shall receive power when the Holy Spirit has come upon you"): through it the disciples are given speech to convert thousands in Jerusalem, forming the first church (the term is used for the first time in Acts 5). One issue debated by scholars is Luke's political vision regarding the relationship between the early church and the Roman Empire. On the one hand, Luke generally does not portray this interaction as one of direct conflict. Rather, there are ways in which each may have considered having a relationship with the other rather advantageous to its own cause. For example, early Christians may have appreciated hearing about the protection Paul received from Roman officials against Gentile rioters in Philippi (Acts 16:16–40) and Ephesus (Acts 19:23–41), and against Jewish rioters on two occasions (Acts 17:1–17; Acts 18:12–17). Meanwhile, Roman readers may have approved of Paul's censure of the illegal practice of magic (Acts 19:17–19) as well as the amicability of his rapport with Roman officials such as Sergius Paulus (Acts 13:6–12) and Festus (Acts 26:30–32). Furthermore, Acts does not include any account of a struggle between Christians and the Roman government as a result of the latter's imperial cult. Thus Paul is depicted as a moderating presence between the church and the Roman Empire. On the other hand, events such as the imprisonment of Paul at the hands of the empire (Acts 22–28) as well as several encounters that reflect negatively on Roman officials (for instance, Felix's desire for a bribe from Paul in Acts 24:26) function as concrete points of conflict between Rome and the early church. Perhaps the most
