Does Paul Teach There Is a Gift of Tongues That Is Not a Known Language, but Between Man and God?

The modern debate over tongues often centers on one specific question: does the New Testament teach the existence of a form of tongues that is not an identifiable human language, but a private or heavenly language spoken between a believer and God?

Acts 2 is clear. At Pentecost, the disciples “began to speak with other languages, as the Spirit gave them the ability to speak” (Acts 2:4, WEB). The miracle is immediately defined: devout Jews from many nations heard them “speaking in our languages the mighty works of God” (Acts 2:11, WEB). The languages were real, recognizable, and tied to identifiable ethnic groups. Nothing in Acts 2 suggests ecstatic speech detached from human language.

The events in Acts 10 and Acts 19 echo Pentecost. When the Spirit falls on Cornelius’ household, Jewish believers recognize the event because they hear them speak in tongues and magnify God (Acts 10:46, WEB). In Ephesus, new believers speak in tongues and prophesy (Acts 19:6, WEB). In Acts, tongues function as visible signs marking key transitions in redemptive history. The pattern remains consistent with Pentecost.

The difficulty arises in 1 Corinthians 12–14, where Paul addresses tongues in the context of congregational worship. Here Paul writes, “For he who speaks in another language speaks not to men, but to God; for no one understands; but in the Spirit he speaks mysteries” (1 Corinthians 14:2, WEB). This verse is often cited as evidence for a non-human, purely heavenly language.

However, context must govern interpretation.

In Corinth, tongues were being spoken publicly without interpretation. Paul’s point is not to redefine tongues as non-human language but to explain the practical result of uninterpreted speech. If no one present understands the language being spoken, then functionally it is directed toward God alone. The problem is not that the language is heavenly by nature; the problem is that it is unintelligible to the congregation.

Paul repeatedly insists that interpretation restores edification. “If I pray in another language, my spirit prays, but my understanding is unfruitful” (1 Corinthians 14:14, WEB). The issue is fruitfulness for the gathered church. He continues, “I will pray with the spirit, and I will pray with the understanding also” (1 Corinthians 14:15, WEB). Understanding remains essential. He does not elevate unintelligibility as superior spirituality.

The phrase “speaks mysteries” (1 Corinthians 14:2) must also be understood in Paul’s vocabulary. Earlier in the letter, Paul describes the gospel itself as once being a mystery (1 Corinthians 2:7, WEB). A mystery in Scripture is not something inherently unknowable but something once hidden and now revealed. When someone speaks in a language unknown to the hearers, what is spoken remains mysterious until interpreted.

Another text often cited is 1 Corinthians 13:1: “If I speak with the languages of men and of angels, but don’t have love, I have become sounding brass” (WEB). Some argue that “languages of angels” implies a distinct heavenly tongue. Yet Paul frequently uses rhetorical exaggeration in this chapter. He speaks of knowing all mysteries, having all knowledge, and having faith to move mountains (1 Corinthians 13:2, WEB). The emphasis is not on cataloging categories of tongues but on elevating love above every gift. The phrase “languages of angels” functions rhetorically, not as a doctrinal classification.

Throughout 1 Corinthians 14, Paul never encourages believers to seek private ecstatic experience detached from understanding. Instead, he subordinates tongues to prophecy because prophecy builds up the church through intelligible speech. “He who prophesies speaks to men for their edification, exhortation, and consolation” (1 Corinthians 14:3, WEB). Edification is corporate.

If tongues were entirely separate from human language, interpretation would not necessarily restore intelligibility. Yet Paul treats interpretation as making the message understandable. “If there is no interpreter, let him keep silent in the assembly” (1 Corinthians 14:28, WEB). Silence is preferable to speech that does not edify.

It is also significant that Paul never describes tongues as the normative private prayer life of every believer. He asks rhetorically, “Do all speak with tongues?” (1 Corinthians 12:30, WEB). The implied answer remains no. Tongues are a gift distributed by the Spirit according to His will (1 Corinthians 12:11, WEB). They are not universal, nor are they presented as required evidence of spiritual maturity.

The broader biblical pattern consistently treats languages as real, meaningful communication. At Babel, God confuses human speech by multiplying languages (Genesis 11:7, WEB). At Pentecost, He reverses confusion by enabling cross-linguistic proclamation. The redemptive trajectory moves toward intelligible unity, not ecstatic fragmentation.

Some argue that when Paul says, “He who speaks in another language edifies himself” (1 Corinthians 14:4, WEB), this supports a private prayer language. Yet even here, Paul does not commend self-edification as the goal of corporate worship. His argument contrasts self-edification with church edification. The latter is superior. “Let all things be done for edification” (1 Corinthians 14:26, WEB). The controlling principle remains communal strengthening.

Scripture does not explicitly describe a category of tongues defined as non-human syllables between an individual and God. It does describe tongues as Spirit-enabled speech requiring interpretation when unknown to hearers. Whether those languages were always earthly or occasionally heavenly is debated, but the text itself never clearly defines a separate private category detached from intelligibility.

The safest conclusion is that Paul teaches a genuine gift of tongues within the early church, functioning as real speech given by the Spirit, requiring interpretation for corporate edification, and never intended to produce disorder or replace understanding.

What Scripture emphasizes consistently is clarity, edification, order, and love. “God is not a God of confusion, but of peace” (1 Corinthians 14:33, WEB). The Spirit who inspires speech also values intelligibility.

The debate should not be driven by reaction or experience but by careful reading. Where Scripture speaks clearly, we affirm it. Where it does not define categories explicitly, we avoid building certainty beyond what is written.

Because spiritual maturity is not measured by the possession of a particular gift, but by conformity to Christ and obedience to His Word.
