Brief Answer

The book of Acts was written by Luke, a physician and companion of the Apostle Paul. Luke is also the author of the Gospel of Luke, and both works are addressed to a man named Theophilus, forming a two-part narrative that traces the life of Jesus and the early church’s growth through the power of the Holy Spirit.

Understanding the Authorship of Acts from a Biblical Perspective

Luke’s authorship of Acts is supported by internal and external evidence:

• Internal Evidence:
  • Acts begins with a reference to a “former book” written to Theophilus, connecting it to the Gospel of Luke (Acts 1:1).
  • The detailed, orderly narrative reflects Luke’s background as a physician and historian (Colossians 4:14).
  • The “we” sections in Acts (e.g., Acts 16:10-17) suggest the author was a companion of Paul, corroborating Luke’s presence in Paul’s ministry.
• External Evidence:
  • Early church tradition affirms Luke as the author. Church fathers such as Irenaeus, Clement of Alexandria, and Eusebius identify Luke as the writer of both Luke and Acts.

This dual authorship gives Luke the distinction of contributing the largest volume of material in the New Testament.

Historical Context

Luke’s background and role in the early church shed light on his authorship:

• Luke the Physician: Colossians 4:14 identifies Luke as a doctor, suggesting he was educated, meticulous, and observant—qualities reflected in his writings.
• Companion of Paul: Luke traveled extensively with Paul, providing firsthand accounts of events recorded in Acts (e.g., Acts 20:5-15).
• Theophilus: Both the Gospel of Luke and Acts are addressed to Theophilus, likely a high-ranking individual or a representative of a broader audience interested in Christianity.

Luke’s perspective as a Gentile and his association with Paul gave him unique insights into the spread of the gospel to the Gentile world.

Practical Implications

Understanding Luke’s authorship of Acts provides practical lessons for believers:

• The Importance of Testimony: Luke’s detailed accounts remind us of the value of recording and sharing God’s work in our lives.
• Faithful Service: Luke’s commitment to accompany Paul, even during trials, illustrates the importance of supporting others in ministry (2 Timothy 4:11).
• Historical Foundation: Acts provides a reliable historical record of the early church, reinforcing the authenticity of Christianity.

Theological Depth and Insight

Acts reveals profound theological truths about God’s work through His church:

1. The Role of the Holy Spirit: Acts emphasizes the Spirit’s empowerment of believers for ministry and mission (Acts 1:8).
2. The Universality of the Gospel: Luke’s narrative shows the gospel breaking cultural and ethnic barriers, fulfilling God’s promise to bless all nations (Acts 10:34-35).
3. God’s Sovereignty: The events in Acts demonstrate how God orchestrates history to fulfill His purposes, even amid persecution and opposition.

Acts continues the story of Jesus’ ministry through the church:
