What is the gift of tongues?

The gift of tongues enters the biblical story dramatically. Fifty days after the resurrection, the Holy Spirit descended on the gathered disciples, and "they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance" (Acts 2:4). What followed was not confused babbling but a striking, orderly miracle that immediately drew a large, bewildered crowd.

Understanding this founding scene carefully matters, because it sets the baseline for everything the New Testament says afterward about this particular gift, including Paul's more complicated later discussion of it in Corinth.

Jerusalem at Pentecost was filled with Jewish pilgrims from across the Roman world, speaking many different native languages. The crowd's own astonished reaction describes exactly what they experienced: "how is it that we hear, each of us in his own native language... we hear them telling in our own tongues the mighty works of God" (Acts 2:8,11). This was not an unintelligible ecstatic utterance; it was real, identifiable human language, understood instantly by native speakers who had never taught it to the disciples.

The effect was evangelistic and unifying rather than confusing. Where the tower of Babel had once scattered humanity through the confusion of languages (Genesis 11:1-9), Pentecost pictured a reversal, as the gospel began reaching every nation represented in that crowd in their own native tongue.

By the time Paul writes to Corinth, tongues had become a source of both blessing and disorder in that congregation. He lists tongues among the Spirit's gifts (1 Corinthians 12:10) but spends significant space in chapter 14 correcting how the gift was being misused in public worship. His central concern was intelligibility: "one who speaks in a tongue speaks not to men but to God; for no one understands him" (1 Corinthians 14:2), unless someone present could interpret.

Because of this, Paul required that tongues spoken publicly be accompanied by interpretation, and if no interpreter was present, the person was to remain silent in the gathering and speak only to himself and to God (1 Corinthians 14:27-28). Uninterpreted tongues in a public service, he says plainly, do not build up the church, since the whole point of gathered worship is mutual edification (1 Corinthians 14:26).

Paul also assigns tongues a specific evangelistic function: "tongues are a sign not for believers but for unbelievers" (1 Corinthians 14:22), echoing the sign-value tongues had already shown at Pentecost, where the miracle itself drew unbelieving crowds and opened the door for Peter's gospel sermon. This purpose distinguishes tongues from gifts oriented purely inward toward the existing church body.

Faithful, Bible-believing Christians disagree on whether tongues and certain other sign gifts continue in the same form today. Continuationists point to no explicit New Testament statement that tongues have ceased, and to ongoing reports of the gift among believers worldwide. Cessationists point to passages like 1 Corinthians 13:8-10, which speaks of tongues ceasing and knowledge passing away, and argue that sign gifts served a foundational, authenticating purpose tied especially to the apostolic era and the initial spread of the gospel before the New Testament was complete.

This is a secondary matter on which Scripture does not speak with the same clarity it uses for essential doctrines, and believers on both sides should extend genuine charity to one another rather than treating the disagreement as a test of true faith.

Whatever view a believer holds on tongues today, Paul's overriding concern applies regardless: gifts exercised without love accomplish nothing lasting. "If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal" (1 Corinthians 13:1). Any believer who possesses this gift, or longs for it, should measure its use not by how impressive or spiritual it appears but by whether it genuinely serves and edifies others in an orderly, loving way.

One question causes real anxiety for some believers: if tongues is such a prominent gift in Acts, does every Christian need to speak in tongues as proof they have truly received the Holy Spirit? Some traditions teach exactly this, treating tongues as the required initial evidence of Spirit baptism. Scripture itself, however, answers the question directly and puts this fear to rest.

Immediately after listing spiritual gifts, including tongues, Paul asks a series of rhetorical questions expecting the answer no: "Do all speak with tongues? Do all interpret?" (1 Corinthians 12:30). The Greek grammar assumes a negative answer throughout the whole list. If tongues were required evidence of the Spirit's presence in every believer, Paul's own question would make no sense, since he is clearly describing a gift given selectively, like healing or administration, not universally like love or joy.

This matters pastorally because sincere believers sometimes conclude, wrongly, that their salvation is somehow incomplete because they have never spoken in tongues. Assurance of the Spirit's presence rests on trusting Christ, not on any particular gift (Romans 8:9, Ephesians 1:13). A believer without this gift is no less filled with the Spirit than one who has it; they are simply gifted differently, exactly as 1 Corinthians 12 describes the body's intentional diversity.
