Introduction
Without Acts, the New Testament would jump from the empty tomb straight to the letters of Paul, with no story to explain how a handful of Galilean disciples became churches in Rome, Corinth and Ephesus. Acts fills that gap. It is the second volume of a two-part work by the same author as the Gospel of Luke, and it narrates about thirty years of history, from the ascension of Jesus to Paul's imprisonment in Rome.
The traditional title, the Acts of the Apostles, is a little narrow. Most of the twelve apostles disappear after the first chapters, and the real protagonist is the risen Lord, working through his Spirit. Acts is a book about mission: it shows the church praying, preaching, suffering, debating and crossing one border after another until the message of Jesus reaches the capital of the world.
Who wrote Acts and when?
The link with the Gospel of Luke
Acts opens by addressing Theophilus and recalling a first book about all that Jesus began to do and teach (Acts 1:1). The Gospel of Luke is dedicated to the same man (Luke 1:3), and both books share vocabulary, style and interests such as prayer, the Holy Spirit, the poor and the inclusion of outsiders. Luke ends with the promise of power from on high and the ascension (Luke 24:49-51); Acts begins with the same scenes.
The we passages
In four stretches the narrator suddenly writes we instead of they (16:10-17; 20:5-15; 21:1-18; 27:1-28:16). The simplest explanation is that the author was there, joining Paul at Troas, staying behind at Philippi and later sailing with him to Jerusalem and to Rome. Among Paul's known companions, Luke fits well: he is with Paul in Rome according to Colossians 4:14 and Philemon 24. From the second century on, Irenaeus and other writers name Luke, and no other author was ever proposed in the early church.
Dating views
- Early 60s AD. The book ends with Paul awaiting trial, around AD 62, and says nothing of his death, of Nero's persecution in AD 64 or of the destruction of Jerusalem in AD 70. Many evangelical scholars think Luke wrote at about that time.
- AD 70-90. Many other scholars think Luke's Gospel used Mark and was written after AD 70, which would place Acts somewhat later. They explain the ending as a deliberate literary choice.
Literary style and structure
History told with care
Luke writes as a Greek historian would, with a dedication, a clear sequence of events and precise details. He gets titles right that changed from place to place: proconsuls govern Cyprus and Achaia (13:7; 18:12), Philippi is a Roman colony with its own magistrates (16:12, 20-22), and Thessalonica has city officials called politarchs (17:6), a title confirmed by inscriptions.
Speeches and summaries
Somewhere between a quarter and a third of the book is made up of speeches: Peter at Pentecost and in the temple, Stephen before the council, Paul in the synagogue of Pisidian Antioch, at the Areopagus, before the Ephesian elders and before Agrippa. Luke condenses them, but they show how the gospel was preached to Jews, to pagans and to rulers. Between the episodes, short summaries report that the word of God kept growing (6:7; 9:31; 12:24; 16:5; 19:20), dividing the book into panels.
Two halves and an expanding map
The structure follows Acts 1:8: Jerusalem (1-7), Judea and Samaria (8-12), and the ends of the earth (13-28). Peter dominates the first half and Paul the second, and Luke draws deliberate parallels between them:
- Both heal a man lame from birth (3:1-10; 14:8-10).
- Both confront a sorcerer (8:18-24; 13:6-11).
- Both see healings through unusual means, Peter's shadow and Paul's handkerchiefs (5:15; 19:11-12).
- Both raise the dead (9:36-41; 20:9-12).
- Both are freed from prison by divine intervention (12:6-11; 16:25-26).
The point is that the same Lord works through the apostle to the Jews and the apostle to the Gentiles.
Acts in the story of the Bible
Acts stands between the Gospels and the letters. It continues the Gospel of Luke and gives the setting for many of Paul's letters: Philippians, 1 and 2 Thessalonians, 1 and 2 Corinthians and Ephesians are written to churches whose founding Acts describes (16-20).
The book is also full of the Old Testament. Peter explains Pentecost with Joel's promise that God would pour out his Spirit on all flesh (2:16-21) and proves the resurrection from Psalm 16 and Psalm 110 (2:25-35). The believers pray Psalm 2 under threat (4:25-26). Stephen retells Israel's story from Abraham to Solomon's temple (7:2-50). Isaiah 53 opens the conversation with the Ethiopian official (8:32-35); Isaiah 49:6, the servant as a light for the nations, justifies the turn to the Gentiles (13:47); Amos 9:11-12 supports the decision of the Jerusalem Council (15:16-18); and the book ends with Isaiah 6:9-10 (28:25-28). Peter also reminds his hearers of the promise to Abraham that all the families of the earth would be blessed (3:25).
Many readers see Pentecost, where people of many languages hear one message, as God's answer to the scattering of the nations at Babel (Genesis 11). Acts presents itself as the fulfillment of the Scriptures: the restored people of God, with Gentiles included, living in the last days that the prophets announced.
Acts and Jesus Christ
Acts is not only about the church; it is about Jesus at work after his ascension. He gives commands through the Spirit (1:2), pours out the Spirit he received from the Father (2:33), adds to the church those who are being saved (2:47) and appears in person at decisive moments: to Stephen, standing at the right hand of God (7:55-56); to Saul, asking why he persecutes him, which shows that to persecute the church is to persecute Christ (9:4-5); and to Paul in Corinth and Jerusalem, promising his presence (18:9-10; 23:11).
The sermons give Jesus a rich set of titles: Lord and Christ (2:36), the Author of life (3:15), the prophet like Moses (3:22), the rejected stone that became the cornerstone (4:11), Leader and Savior (5:31) and the one appointed to judge the living and the dead (10:42; 17:31). Their message is always the same: Jesus was crucified, God raised him and exalted him, and forgiveness of sins is offered in his name to everyone who believes (2:38; 10:43; 13:38-39). Salvation is found in no one else (4:12).
Interpretive challenges
Description or prescription?
Acts tells what happened; not everything it tells is meant to be repeated. The early believers in Jerusalem shared their possessions voluntarily (2:44-45; 4:32-37), but Peter makes clear that Ananias was free to keep his land (5:4). The usual approach is to look for what Luke presents as a pattern, repeated and approved across the book, and to read single events in the light of the teaching of the letters.
Why does the Spirit come in different ways?
At Pentecost the Spirit comes on believers who were waiting (2:1-4); in Samaria the Spirit is given only when Peter and John lay hands on baptized believers (8:14-17); with Cornelius the Spirit falls before baptism (10:44-48); and in Ephesus disciples who knew only John's baptism receive the Spirit after being baptized in the name of Jesus (19:1-7). Some interpreters see these as unique moments that mark the entry of each new group into the church, after which every believer receives the Spirit at conversion. Others see in them a pattern of a distinct filling or empowering that believers may still seek. Both views agree that the Spirit is God's gift to all who belong to Christ (2:38-39).
How does Acts fit with Paul's letters?
Readers sometimes notice differences, such as Paul circumcising Timothy (16:3) while insisting in Galatians that circumcision adds nothing to salvation, or the number of Paul's visits to Jerusalem. Most evangelical scholars think the accounts fit once purpose is considered: Timothy, of Jewish mother, was circumcised to open doors among Jews, not to be saved, and the visits of Galatians 1-2 can be matched with Acts 9, 11 and 15 in reasonable ways.
Little-known facts
- Luke wrote more of the New Testament than Paul. Measured by words, Luke and Acts together make up more than a quarter of the New Testament.
- Saul was not renamed at his conversion. Luke keeps calling him Saul for several years and switches to Paul only in Cyprus, noting that he was also called Paul (13:9). As a Jew with Roman citizenship, he probably had both names from childhood.
- The name Christians began in Antioch (11:26). It appears only three times in the New Testament (Acts 11:26; 26:28; 1 Peter 4:16).
- A saying of Jesus not found in the Gospels. Paul reminds the Ephesian elders that the Lord said it is more blessed to give than to receive (20:35).
- Outside sources confirm details. The Jewish historian Josephus also describes the sudden death of Herod Agrippa I at Caesarea (12:20-23), and the Delphi inscription naming Gallio helps date Paul's stay in Corinth to about AD 51-52.
- The ship to Rome carried 276 people (27:37), and all of them reached the shore of Malta alive (27:44).
How to study Acts
A reading plan
Read Acts first in two or three sittings to feel the momentum of the story, then slowly, one chapter a day for four weeks. Keep a map of the eastern Mediterranean at hand and trace each journey; the geography is part of the message.
What to look for
- Every mention of the Holy Spirit and what he does.
- The summary reports of growth and where they fall.
- The speeches: what each preacher says about Jesus and how he adapts to his audience.
- The new groups that receive the gospel: Samaritans, an Ethiopian, Roman soldiers, Greek philosophers, women of business, jailers.
- How the church responds to opposition and to internal conflict.
Teaching it in a class or small group
An eight or nine week series can follow the outline: Pentecost; the Jerusalem church; Stephen and Philip; Saul's conversion; Cornelius; the first journey and the council; the second journey; the third journey; arrest, trials and Rome. In each session ask three questions: What did God do? How did the believers respond? What would faithful witness look like in our town this week? Acts is best taught not as a museum of the past but as the first chapters of a story that continues in every church that prays and proclaims Jesus.
