Meaning of "speaks in a tongue"?
What does 1 Corinthians 14:2 mean by "speaks in a tongue"?

Text

“For the one who speaks in a tongue does not speak to men but to God. Indeed, no one understands him; he utters mysteries in the Spirit.” (1 Corinthians 14:2)


Historical Setting in Corinth

Corinth was multilingual: Greek, Latin, Hebrew-Aramaic, Phrygian, and Egyptian dialects circulated among merchants, veterans, and freedmen. Converts experienced the same pentecostal sign (Acts 2:4; 10:46; 19:6), but disorder erupted when believers exercised the gift publicly without interpretation (14:23). Paul corrects the abuse—not the gift—so that worship glorifies God and instructs the church.


Godward Orientation of the Gift

Paul says the speaker “does not speak to men but to God.” This vertical trajectory parallels “praying in the Spirit” (Ephesians 6:18; Jude 20) and fulfills prophecy: “I will pour out My Spirit … your sons and daughters will prophesy” (Joel 2:28). Mystērion (“mysteries”) refers to divine truths unveiled by the Spirit (1 Corinthians 2:10). Thus tongues function primarily as worship, prayer, and thanksgiving (14:15-17).


Contrast with Prophecy

Prophecy edifies the congregation intelligibly; un-interpreted tongues edify only the speaker (14:3-5). Paul therefore requires interpretation (hermēneia, v. 13), grounding the rule in Isaiah 28:11-12—a judgment oracle in which foreign speech signaled covenantal warning. Tongues, then, are a sign both of blessing (Spirit outpouring) and of judgment (confusion for unbelief).


Private Devotion vs. Public Assembly

In private, the believer “builds up himself” (v. 4); in corporate worship, two or three may speak “each in turn,” with interpretation (v. 27). Disorder violates the Spirit’s nature: “God is not a God of confusion, but of peace” (v. 33).


Languages of Men and of Angels

1 Cor 13:1 mentions “tongues of men and of angels.” “Men” confirms known human languages (Acts 2:8-11). “Angels” suggests a supra-human linguistic mode, echoing heavenly worship scenes (Revelation 5:11-12). Either way, intelligibility to listeners is absent without interpretation.


Biblical Coherence: Babel to Pentecost

Genesis 11 records Yahweh’s deliberate diversification of human language; Acts 2 depicts temporary reversal as diverse hearers understand “the mighty works of God” (v. 11). Tongues therefore dramatize redemption history: God overcomes linguistic fracture through Christ’s Spirit.


Early Church Witness

Irenaeus (Against Heresies 5.6.1) testifies, “We hear many brethren … who speak in all kinds of tongues.” Origen (Contra Celsum 7.4) and Tertullian (On Baptism 20) echo the continuation of the gift. No patristic source describes tongues as incoherent gibberish; they assume genuine languages or inspired “psalms and hymns.”


Archaeological Parallels: Ebla & Ugarit

Discoveries of Ebla tablets (c. 2300 B.C.) and Ugaritic texts (c. 1400 B.C.) reveal sophisticated Semitic vocabularies predating evolutionary linguistics and aligning with a young-earth framework that places advanced language near humanity’s origin—a hallmark of intelligent design and harmony with Genesis.


Modern Confirmations and Missional Utility

Documented missionary reports detail spontaneous speech understood by native hearers (e.g., Sudan, 1972; Papua, 1984), resulting in conversions. Such accounts, vetted by on-site linguists, parallel Acts 2 phenomena and affirm the evangelistic purpose Paul commends when interpretation—or divine providence—yields comprehension.


Theological Significance

Tongues witness to Jesus’ resurrection power, distributed by the ascended Christ (Acts 2:33). They presuppose the Triune God: the Father sends the Spirit in the name of the Son. As with other gifts, tongues aim at the church’s growth and God’s glory, never personal prestige.


Practical Guidelines for Today

• Seek love first (14:1).

• Pursue intelligibility via interpretation (14:13-19).

• Maintain order (14:27-33).

• Submit to tested doctrine (14:37-38).

When exercised biblically, the gift remains a living testimony to God’s sovereign grace and the truthfulness of Scripture.


Summary Definition

To “speak in a tongue” in 1 Corinthians 14:2 is to utter a real, Spirit-generated language—whether human or angelic—directed to God, incomprehensible to bystanders without interpretation, and intended as a sign of the new-covenant outpouring of the Holy Spirit that points unmistakably to the risen Christ.
