1 Corinthians 12:13
For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
Primary
What this passage establishes
By one Spirit believers are formed into one body and made to drink of one Spirit.
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.
