Acts 19:2
He said unto them, Have ye received the Holy Ghost since ye believed? And they said unto him, We have not so much as heard whether there be any Holy Ghost.
Primary
What this passage establishes
Paul asks existing disciples directly whether they received the Holy Ghost after believing.
Why it matters in the argument
Acts gives observable accounts of people receiving the promised Spirit. Those narratives supply the Bible’s clearest pattern for recognizing Spirit reception.
Apostolic connection
Apostolic teaching distinguishes the initial sign of tongues when the Spirit is received from the later congregational gift that requires interpretation.
Common misunderstanding
Paul’s question ‘do all speak with tongues?’ concerns distributed gifts in the assembled body, not the repeated initial sign in Acts.
How to use it in conversation
Start with the promise, then compare Acts 2, 10, and 19. Use 1 Corinthians only after distinguishing initial sign, private prayer, and public gift.
