The Book of Acts, authored by Luke the Evangelist, serves as a critical historical account and theological bridge in the New Testament, chronicling the early Christian community's expansion from Jerusalem into the wider Greco-Roman world. This transition from a predominantly Jewish audience to a Gentile one is one of the central themes of Acts and reflects a significant evolution in the understanding and scope of the Christian mission.
The narrative of Acts begins with the ascension of Jesus and the descent of the Holy Spirit at Pentecost, events deeply rooted in Jewish tradition and symbolism. The initial chapters focus on the apostles’ ministries in Jerusalem and their interactions with Jewish religious authorities. Peter’s early sermons, such as the one in Acts 2:14-41, are directed primarily at Jews, quoting extensively from the Hebrew Scriptures and interpreting the life, death, and resurrection of Jesus as the fulfillment of Jewish prophecy.
A pivotal moment in the transition of the gospel from a Jewish to a Gentile audience occurs in Acts 10, with the story of Peter and Cornelius. Cornelius, a Roman centurion and a God-fearing Gentile, receives a vision that leads him to send for Peter. Concurrently, Peter has a vision of a sheet containing unclean animals, which he is instructed to eat, symbolizing the abolition of traditional Jewish dietary laws. The voice in Peter’s vision declares, “What God has made clean, do not call common” (Acts 10:15).
This dual vision serves as a divine directive that the gospel is to be preached to Gentiles as well as Jews, breaking the longstanding barriers of religious exclusivity. Peter’s subsequent visit to Cornelius’s house and the outpouring of the Holy Spirit on all present, regardless of their Jewish or Gentile status, signifies a dramatic shift. Peter himself acknowledges this transformation when he says, “Truly I understand that God shows no partiality, but in every nation anyone who fears him and does what is right is acceptable to him” (Acts 10:34-35).
Following the account of Peter and Cornelius, the focus of Acts shifts significantly towards Paul, formerly Saul of Tarsus, a Pharisee who becomes the apostle to the Gentiles. Paul's missionary journeys, which occupy the latter half of Acts, underscore the expansion of the Christian message beyond the confines of Jewish culture and law.
Paul’s approach to evangelism was marked by his ability to adapt his message to diverse audiences. In his engagements, he strategically utilized his dual identity as a Jew and a Roman citizen to bridge cultural and religious divides. His sermon on Mars Hill (Acts 17:22-31) is a prime example of this method. Addressing the Athenians, Paul references their own religious observances and even quotes their poets to connect the gospel message to their philosophical inquiries.
The Jerusalem Council, detailed in Acts 15, addresses the question of whether Gentile converts should be required to observe Jewish law, particularly circumcision. This council marks a crucial institutional endorsement of the mission to the Gentiles. The apostles and elders, including key figures like Peter and James, conclude that imposing Jewish customs on Gentile believers would be an unnecessary burden. Instead, they send a letter to Gentile Christians affirming their freedom from these obligations, while urging them to abstain from practices particularly offensive to Jewish Christians, such as consuming food offered to idols and sexual immorality (Acts 15:19-29).
Theologically, the transition depicted in Acts reflects a profound understanding of the gospel as a message of universal salvation. This is articulated in several key speeches and events throughout the book, emphasizing that the salvation offered by Jesus Christ is not confined to a single ethnic group or cultural tradition but is available to all humanity. This universalist perspective is perhaps most eloquently expressed in Paul’s letter to the Galatians, where he writes, “There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus” (Galatians 3:28).
In summary, the Book of Acts portrays the transition of the gospel from a Jewish to a Gentile audience as a divinely orchestrated expansion of the Christian mission. This transition is characterized by key events and decisions, such as the inclusion of Cornelius and his household, the missionary activities of Paul, and the resolutions of the Jerusalem Council. Through these developments, Acts not only recounts the historical spread of Christianity but also articulates a theological vision of the gospel’s universal scope and inclusivity, challenging the early Christian community to embrace a broader and more diverse understanding of God’s salvific work.
