What role does the Holy Spirit play in the Gospel According to Luke and Acts of the Apostles?

In the writings of St. Luke, the Holy Spirit serves as the vital link between the ministry of Jesus and the mission of the early church, acting as the guiding force that unfolds God’s plan of salvation across history.1

The Role of the Holy Spirit in Luke–Acts

Luke structures his two-volume work into distinct historical epochs, with the Holy Spirit functioning as the primary agent of transition and continuity:12

• The Ministry of Jesus: In the Gospel, Jesus is depicted as being endowed by the Holy Spirit, who guides his ministry from Nazareth to Jerusalem. The Spirit is central to his message, his acts of healing, and his overall mission.13
• The Birth of the Church: In the Acts of the Apostles, the Holy Spirit is the catalyst for the "new dispensation" of the church. The event of Pentecost—the outpouring of the Spirit upon the disciples—marks the beginning of the church's mission to spread the word from Jerusalem to the ends of the earth.31
• Ongoing Guidance: Throughout Acts, the Spirit is portrayed as the source of power for the apostles, associated with prophecy, healing, and the expansion of the church’s witness.41

By emphasizing the Spirit’s role, Luke illustrates that the church’s mission is not merely a human endeavor but an orderly progress directed by God’s divine plan.1
