Luke–Acts as a Two-Volume Work

Introduction

The Gospel of Luke and the Acts of the Apostles together comprise the longest narrative in the New Testament. Written by the same author, addressed to the same addressee (Theophilus), and united in style and theology, they form a single, two-volume work often referred to as Luke–Acts. Reading them together is essential to grasping Luke’s theological vision: a comprehensive salvation history that begins with Israel’s Scriptures, reaches its climax in Jesus, and continues in the Spirit-empowered mission of the church.

In this article, we will explore the literary, historical, theological, and pastoral dimensions of Luke–Acts as a unified work.

Part 1: Literary Unity of Luke–Acts

1. Common Authorship

Both Luke and Acts begin with prologues addressed to “Theophilus” (Luke 1:1–4; Acts 1:1–2). The polished Greek, historiographical style, and thematic concerns identify them as the work of the same author, traditionally known as Luke, a companion of Paul (Colossians 4:14; 2 Timothy 4:11).

2. Similar Style and Vocabulary

Luke–Acts shares distinctive vocabulary and stylistic features, such as frequent medical terms, elevated Greek in introductions, and a fondness for certain words (e.g., sōtēria “salvation,” plēroō “fulfill”). Scholars estimate that more than 30% of Luke’s vocabulary is unique in the New Testament, and this unique diction carries over into Acts.

3. Structural Parallels

• Luke begins with Jesus’ birth; Acts begins with the church’s “birth” at Pentecost.

• Luke narrates Jesus’ journey to Jerusalem; Acts narrates the Gospel’s journey from Jerusalem to Rome.

• In Luke, Jesus is Spirit-empowered; in Acts, the church is Spirit-empowered.

The unity of these volumes is not accidental but deliberate.

Part 2: Historical Continuity

1. From Jesus to the Church

Luke’s Gospel narrates “all that Jesus began to do and teach” (Acts 1:1). Acts continues the story with what Jesus continues to do through the Spirit and the apostles. This transition reflects Luke’s theology of salvation history: God’s plan unfolds progressively, not in isolated episodes.

2. Apostolic Witness

Luke–Acts emphasizes eyewitnesses: in the Gospel, disciples see and hear Jesus; in Acts, they testify to what they have experienced. The apostles serve as a bridge between Jesus’ ministry and the church’s mission.

3. The Geographic Expansion

• Luke: Focus is on Galilee → Jerusalem.

• Acts: Focus is on Jerusalem → Judea → Samaria → Rome (the symbolic “ends of the earth”).

This movement reveals Luke’s vision of salvation spreading outward in widening circles.

Part 3: Theological Themes

1. Salvation History

Luke presents the Gospel and Acts as parts of one great story: the fulfillment of God’s promises. From the songs of Mary and Simeon to Paul’s preaching in Rome, Luke underscores that salvation history is unfolding according to divine plan.

2. The Kingdom of God

• In Luke, Jesus proclaims the kingdom in parables and miracles.

• In Acts, the apostles continue to preach the kingdom (Acts 28:31).

Luke–Acts presents a consistent picture: the kingdom is already inaugurated in Jesus but continues to advance through the church.

3. The Holy Spirit

The Spirit is central in both volumes:

• Luke: Spirit empowers Jesus’ conception, baptism, preaching, and miracles.

• Acts: Spirit empowers Pentecost, missionary journeys, and the life of the church.

The Spirit links the ministry of Jesus to the mission of the church.

4. Universal Salvation

Luke’s emphasis on salvation for all — Jews, Gentiles, men, women, rich, poor, insiders, outsiders — is carried forward in Acts. The inclusion of Gentiles through Peter (Acts 10–11) and Paul (Acts 13–28) embodies the Gospel’s universal scope.

Part 4: Narrative Structure

1. Gospel of Luke

• Infancy narratives (Luke 1–2).

• Ministry in Galilee (3–9).

• Journey to Jerusalem (9:51–19:27).

• Passion and resurrection (19:28–24).

2. Acts of the Apostles

• Jerusalem: Pentecost and the early church (Acts 1–7).

• Judea and Samaria: Expansion amid persecution (Acts 8–12).

• Gentile mission: Paul’s journeys (Acts 13–21).

• Rome: Paul’s arrest and preaching in the imperial capital (Acts 22–28).

This two-part structure moves the story from Jesus in Israel to the Gospel in the world.

Part 5: Purpose and Audience

1. Strengthening Theophilus

Luke dedicates both volumes to Theophilus (Luke 1:3; Acts 1:1). Whether Theophilus was a patron, official, or symbolic “lover of God,” Luke’s aim is to provide certainty about the Christian faith.

2. Apologetic Purpose

Luke–Acts presents Christianity as the fulfillment of Israel’s hopes and a legitimate faith within the Roman world. Paul’s trials in Acts demonstrate that Christianity is not politically subversive but rooted in divine truth.

3. Pastoral Aim

Luke writes to encourage believers facing opposition. By situating their story within God’s grand plan, he assures them that their faith is secure.

Part 6: Implications for Interpretation

1. Reading Luke and Acts Together

Separating Luke from Acts risks misunderstanding. For example:

• The Gospel emphasizes Jesus’ ministry to Israel; Acts shows that mission extending universally.

• Luke highlights the Spirit empowering Jesus; Acts highlights the Spirit empowering the church.

Only together do we see the full sweep of Luke’s theology.

2. Continuity of Salvation History

Luke–Acts provides the most comprehensive salvation narrative in the New Testament, from birth narratives to Paul’s preaching in Rome. It bridges the story of Jesus with the life of the church.

3. Relevance for Today

For modern readers, Luke–Acts reminds us that Christian faith is not static but dynamic, unfolding across history. The same Spirit that empowered Jesus and the apostles continues to empower the church today.
