A distinct second experience
Conversion brings the Spirit. Baptism in the Spirit is a further empowering for witness.
What it claims
The New Testament describes an enduement of power that is distinct from and usually subsequent to being born again. Jesus' own disciples are the pattern: they are already believers, already sent, already breathed on in John 20, and they are still told to wait in Jerusalem until they are clothed with power from on high. Waiting for something implies not yet having it. In classical Pentecostal teaching, speaking in tongues is the initial physical evidence that it has happened, though the wider charismatic renewal generally holds the experience without insisting on that sign.
Who holds it
Classical Pentecostal denominations: Assemblies of God, Church of God in Christ, Foursquare, Apostolic Faith bodies, and the Wesleyan-Holiness churches they grew out of.
The texts it stands on
- Luke 24:49 Told to wait for power, after the resurrection and the commission.
- Acts 1:4-8 You will receive power when the Holy Spirit has come upon you. Power for witness, not for salvation.
- Acts 8:14-17 Samaritans had believed and been baptized; the Spirit had not yet fallen on any of them.
- Acts 19:1-6 Paul asks disciples whether they received the Spirit when they believed, which is only a sensible question if the two can come apart.
Strongest case
It takes Acts at face value rather than harmonising it away. Luke does describe believers receiving the Spirit after believing, twice, and he does not treat those as irregularities needing explanation. The question Paul asks in Ephesus is the strongest single piece of evidence, because it presumes the possibility of a gap.
Hardest question
Paul never uses the phrase for a second stage. The one time he says baptized in the Spirit he says all of us were, and he says it to a church he is rebuking, some of whom he calls worldly. If the experience were the mark of the empowered, that is the last congregation he would grant it to universally. And the episodes in Acts are transitional by design: Samaria and Caesarea are the gospel crossing ethnic boundaries for the first time, with apostles present precisely so the crossing is witnessed and accepted.
How it answers that
Paul and Luke are not using the same vocabulary for the same thing, and requiring them to is the error. Paul's phrase describes incorporation into the body; Luke's describes an outpouring for mission, and Luke is the one narrating the experience. On the transitional reading, the reply is that Ephesus is not a boundary crossing at all, it is a group of ordinary disciples a long way into the book, and Paul's question there is put in general terms rather than as a special case.
