Final answer:
Luke tries to legitimize Christianity to the Roman authorities.
Step-by-step explanation:
Luke tries to legitimize Christianity to the Roman authorities. In the first century CE, Christianity was seen as a challenge to state religious authority by the Romans. This led to occasional persecution of Christians as the Romans wanted to maintain their control over the population. Luke, as a follower of Jesus, likely sought to provide a more positive image of Christianity to the Roman authorities in order to gain acceptance and tolerance for the new religion.
