How Did People Become Christians in the Book of Acts?
Compare the conversion accounts in Acts—from Pentecost and the Ethiopian eunuch to Saul, Cornelius, Lydia, the jailer, Corinth, and Ephesus—and see the recurring apostolic pattern.
READ THE CONVERSIONS TOGETHER
Acts gives multiple conversion accounts instead of one isolated formula.
One of the easiest mistakes in studying conversion is to select one verse and force every other account through it.
Acts gives us something better: repeated encounters involving different people, backgrounds, questions, and stages of understanding.
Not every narrative repeats every detail. That makes comparison important. What appears when the accounts are placed beside one another?
PENTECOST — ACTS 2
They heard Christ proclaimed, were cut to the heart, repented, and were baptized.
Peter announces the crucified and risen Jesus as Lord and Christ.
His hearers ask what they should do. Peter tells them to repent and be baptized in Jesus Christ's name for the forgiveness of sins, with the promised gift of the Holy Spirit.
Luke then says those who received the message were baptized and added.
The Pentecost hearers ask what to do; Peter calls for repentance and baptism, and those receiving the message are baptized.
SAMARIA — ACTS 8
Philip preached the kingdom and Jesus; men and women believed and were baptized.
Samaria gives a compact description of evangelism and response.
Philip proclaims the good news of God's kingdom and the name of Jesus Christ.
Luke says that when the people believed Philip, both men and women were baptized.
THE ETHIOPIAN — ACTS 8
Hearing the good news about Jesus quickly leads to a question about baptism.
Philip begins with Isaiah and tells the Ethiopian the good news about Jesus.
As they travel, the Ethiopian sees water and asks what prevents him from being baptized.
The narrative is striking because baptism appears naturally inside the evangelistic encounter rather than as a remote ceremony scheduled after Christian initiation.
After Philip proclaims Jesus, the Ethiopian asks about baptism and is baptized.
SAUL — ACTS 9 AND 22
The future apostle encounters Christ—and is still told to act.
Saul's conversion is especially useful because Acts recounts it more than once.
He encounters the risen Jesus, fasts, prays, and waits for Ananias.
When Paul later recounts the event, he remembers Ananias telling him to get up, be baptized, and wash away his sins while calling on the Lord's name.
Ananias tells Saul to rise, be baptized, wash away his sins, and call on the Lord's name.
CORNELIUS — ACTS 10
A unique sign demonstrates that Gentiles are being received—and Peter still commands baptism.
Cornelius is an important case because the Holy Spirit falls upon his household while Peter is speaking.
Peter interprets the event as divine confirmation that Gentiles are not to be excluded.
He then asks whether anyone can withhold water and commands them to be baptized in Jesus Christ's name.
Acts itself therefore keeps the extraordinary sign and the commanded response in the same narrative.
LYDIA AND THE JAILER — ACTS 16
Two very different households hear the message and respond.
Lydia listens as Paul speaks, the Lord opens her heart, and she and her household are baptized.
Later, the terrified Philippian jailer asks Paul and Silas what he must do to be saved. They tell him to believe in the Lord Jesus, then speak the word of the Lord to him and his household.
That same night he washes their wounds and he and his household are baptized.
The jailer asks what he must do to be saved, hears the word of the Lord, and is baptized with his household that night.
CORINTH — ACTS 18
Hearing, believing, and baptism appear together again.
Luke says Crispus believed in the Lord with his household.
He then summarizes the wider response in Corinth: many who heard Paul believed and were baptized.
The sequence is simple enough to miss because Acts treats it as ordinary Christian mission rather than an unusual ritual development.
EPHESUS — ACTS 19
Paul even asks what baptism existing disciples had received.
At Ephesus Paul encounters disciples whose understanding is incomplete.
When he learns they had received John's baptism, he explains John's baptism of repentance and points them to Jesus.
They are then baptized in the name of the Lord Jesus.
For Who Changed the Church?, this account is important because it shows that sincerity alone does not make the content of Christian initiation irrelevant.
WHY DOESN'T EVERY STORY SAY EVERYTHING?
Different summaries emphasize different parts of a larger response.
Acts can say that people believed without repeating every action that appears elsewhere. It can emphasize repentance in one setting, baptism in another, or the proclamation of Jesus in another.
The manuscript argues that this is why conversion accounts should be read cumulatively rather than competitively.
Don describes this through the literary idea of synecdoche: one part of a response can sometimes stand for the whole without denying the other parts explicitly shown elsewhere.
THEN THE BOOK RUNS AN UNUSUAL TEST
What happens if people encounter these passages without a denominational conversion formula?
This is where the biblical study turns into one of the most unusual episodes in Who Changed the Church?.
Don recounts a group of prisoners who agreed to remove preachers, tracts, and outside religious opinions from their investigation. They would simply read the Book.
They reached John's statement about believing. Then they turned into Acts.
What they concluded—and what happened next inside the prison—is deliberately more revealing after the conversion accounts above have been read first.
- Pentecost records hearing, conviction, repentance, baptism, forgiveness, and addition.
- Samaritans believe the good news and are baptized.
- The Ethiopian hears Jesus proclaimed and asks for baptism.
- Saul is told to be baptized and wash away his sins while calling on the Lord.
- Cornelius receives an extraordinary sign and is still commanded to be baptized.
- Lydia and the Philippian jailer respond immediately after hearing the message.
- Corinthians hear, believe, and are baptized.
- The Ephesians receive baptism in the name of the Lord Jesus after their understanding is corrected.
Why It Matters
How did people become Christians in Acts? No single account repeats every word, but together the narratives form a recognizable pattern: Christ is proclaimed, people hear and believe, they turn toward God, and baptism repeatedly appears at the beginning of Christian life. Who Changed the Church? then asks a provocative question the biblical text alone cannot answer for us: if people centuries later stripped away their inherited religious systems and followed these conversion accounts for themselves, would the same pattern appear again? Don says he watched that experiment happen.
