1 Corinthians 14:37

Anyone could easily validate a Corinthian’s claim to being a prophet or spiritual. He could do so by seeing if he or she acknowledged that what Paul had written was authoritative because he was an apostle of the Lord. Submission to apostolic authority was the test, not speaking in tongues. Submissiveness to the apostles and their teaching was an expression of submission to the Lord Himself (cf. 1 Corinthians 7:10; 1 Corinthians 7:25). It still is.
