At Pentecost, the Holy Spirit enabled the apostles to speak in real, identifiable human languages they had never learned, so that "each one was hearing them speak in his own language" (Acts 2:6). This was a sign gift that authenticated the apostolic message and reversed the curse of Babel. In 1 Corinthians 12-14, Paul regulates the use of tongues in the church, requiring interpretation and order. He ranks tongues as the least of the gifts and warns that without interpretation, tongues in the assembly edify no one (1 Corinthians 14:19). Paul also indicates that tongues will cease (1 Corinthians 13:8), though the timing of that cessation is debated.
A language; the whole system of words used by a particular nation.
TONGUE, n. A language; the whole system of words used by a particular nation. The gift of tongues, in Scripture, was the ability to speak in foreign languages — real, identifiable tongues of actual human nations. Webster's definition presupposes that "tongues" meant known languages, not ecstatic utterances.
• Acts 2:4-6 — "And they were all filled with the Holy Spirit and began to speak in other tongues... each one was hearing them speak in His own language."
• 1 Corinthians 14:19 — "In church I would rather speak five words with my mind... than ten thousand words in a tongue."
• 1 Corinthians 13:8 — "As for tongues, they will cease; as for knowledge, it will pass away."
• 1 Corinthians 14:27-28 — "If any speak in a tongue, let there be only two or at most three, and each in turn, and let someone interpret."
Tongues have been redefined from known languages to ecstatic utterances and treated as the supreme evidence of the Spirit.
Modern Pentecostalism and charismatic theology have largely redefined tongues from known human languages (as in Acts 2) to ecstatic, unintelligible utterances — a "prayer language" that bypasses the mind. Many teach that speaking in tongues is the necessary evidence of Spirit baptism, creating a two-tier Christianity where tongue-speakers are spiritually superior to those who do not speak in tongues. This directly contradicts Paul, who asked rhetorically, "Do all speak with tongues?" expecting the answer "No" (1 Corinthians 12:30). The elevation of tongues above other gifts, the practice of tongues without interpretation, and the use of tongues as a test of spiritual authenticity all violate Paul's clear instructions in 1 Corinthians 14.
• "At Pentecost, tongues were known human languages understood by foreign visitors — not unintelligible ecstatic speech."
• "Paul ranked tongues as the least of the gifts and required interpretation in the assembly — the modern elevation of tongues above all other gifts inverts his teaching."
• "The man who insists that tongues are the necessary proof of the Spirit has added a requirement that Scripture never makes."
