1 Corinthians 14:39
1 Corinthians 14:3939So, my brothers, be eager to prophesy, and do not forbid speaking in tongues.
rs argues that tongues have ceased altogether and that modern tongues-speakers have the wrong spirit. In practice this becomes a de facto prohibition of tongues in JW contexts. 14:39 itself — Paul's explicit command not to forbid tongues — is typically not engaged, because it directly blocks the rs conclusion that modern tongues must be treated as spurious.
14:39 in the NWT: "keep zealously seeking the prophesying, and yet do not forbid the speaking in tongues." Paul's explicit rule is: do NOT forbid tongues. The strongest form of cessationism — outright prohibition — is exactly what Paul forbids here. Even a Reformed cessationist has to reckon with this verse. At the door, the move is simple: "Your own rs book effectively forbids tongues by declaring modern tongues-speakers to have the wrong spirit. Paul says do not forbid. One of you is on Paul's side, and it is not the rs book."
