What the Bible says
The New Testament describes two distinct phenomena that are both called "tongues":
Acts 2 — known human languages
At Pentecost (Acts 2), the disciples were filled with the Holy Spirit and began speaking in other languages (heterais glōssais — "other tongues"). The crowd gathered from across the Roman world heard them speaking in their own native languages: "We hear them telling in our own tongues the mighty works of God" (Acts 2:11). This was miraculous speech in known human languages that enabled the Gospel to be heard across linguistic barriers. Similar events are described in Acts 10 and Acts 19.
1 Corinthians 12–14 — unknown spiritual language
Paul's discussion of spiritual gifts in 1 Corinthians 12–14 describes a somewhat different phenomenon: speech in a language unknown to the speaker and unintelligible to the congregation without a separate gift of interpretation. "For one who speaks in a tongue speaks not to men but to God; for no one understands him, but he utters mysteries in the Spirit" (1 Corinthians 14:2). Paul regulates this gift carefully: in a corporate service, tongues should only be exercised with interpretation; otherwise it is not edifying to the congregation.
Whether the Acts tongues and the Corinthian tongues are identical phenomena or distinct has been debated. Most Pentecostal interpreters treat them as the same; many cessationists distinguish between them.
The Pentecostal and charismatic view
Pentecostal Christians (like the Assemblies of God) teach that speaking in tongues is the "initial physical evidence" of the baptism of the Holy Spirit — a subsequent, empowering experience distinct from conversion. This is based on the pattern in Acts, where the baptism of the Spirit is consistently accompanied by speaking in tongues.
In this view:
- Every believer can and should seek the baptism of the Holy Spirit
- Speaking in tongues is the normative, expected sign of this experience
- Tongues in private prayer is a valuable ongoing spiritual practice ("praying in the Spirit")
- The public gift of tongues with interpretation is distinct from private prayer tongues
Charismatic Christians (who hold similar views about the gifts but are spread across denominations — Catholic charismatics, charismatic Anglicans, etc.) generally affirm tongues as a valid gift today but do not always require it as the evidence of Spirit baptism.
The cessationist view
Many Reformed, Baptist, and conservative evangelical theologians hold to cessationism — the view that the miraculous gifts (tongues, prophecy, healing) were given for the apostolic era to authenticate the Gospel and the apostolic message, and ceased when the New Testament canon was completed and the apostolic generation passed.
The key cessationist text is 1 Corinthians 13:8–10 — "As for tongues, they will cease... when the perfect comes, the partial will pass away." Cessationists interpret "the perfect" as the completed New Testament canon; continuationists interpret it as the second coming of Christ.
In cessationist churches, speaking in tongues is not practiced and may be viewed with concern — either as a psychological phenomenon, a counterfeit spiritual experience, or at best an overemphasis on a minor element of the New Testament.
What to expect in a Pentecostal or charismatic church
If you attend a Pentecostal or charismatic service for the first time:
- Private prayer in tongues. You may see people praying quietly in tongues during extended worship or a prayer time. This is personal and not addressed to the congregation.
- A public message in tongues. Occasionally, during a moment of corporate prayer or worship, someone may speak aloud in tongues. This is addressed to the congregation and, in biblically ordered Pentecostal practice, should be followed by an interpretation by someone with that gift.
- You are not expected to participate. Visitors are not expected to speak in tongues or perform any spiritual exercise. Observe with openness and ask questions afterward.
- Not all Pentecostal churches look the same. Some are highly expressive and spontaneous; others are more ordered and restrained. The experience varies significantly by congregation.
Is tongues necessary for salvation?
No — even in classic Pentecostal theology, tongues is the evidence of Spirit baptism, not of salvation itself. Salvation is by grace through faith in Jesus Christ. A person may be genuinely saved and never speak in tongues. The question of Spirit baptism and tongues is a separate discussion from the question of salvation.
Frequently asked questions
Is speaking in tongues demonic or dangerous?
No — but discernment is appropriate. Paul's instructions in 1 Corinthians 14 show that tongues in a corporate setting require order and interpretation. The New Testament does not suggest the gift is demonic; it regulates its use. Christians from non-charismatic backgrounds often experience cultural unfamiliarity, not spiritual danger, when first encountering tongues. Investigate the theology of the church you are attending; a biblically ordered charismatic church is a different environment from an unaccountable group with no pastoral oversight.
Can someone learn to speak in tongues?
Pentecostals would say no — tongues is a gift given by the Holy Spirit, not a learned skill. However, some charismatic teachers encourage believers to open themselves to the experience through prayer and yielding to the Spirit. The debate about the nature of glossolalia — whether it is learned, psychological, or genuinely supernatural — continues in both theological and psychological literature.
