Glossolalia as Prelest

How the modern pursuit of tongues leads to spiritual delusion

Today, many Charismatic and Pentecostal churches place a lot of importance on speaking in tongues, or what’s sometimes called glossolalia. For them, this isn’t just one spiritual gift among several options. Instead, a lot of believers see it as the main evidence that someone has received the “baptism of the Holy Spirit” and has moved into a deeper level of spiritual life.

If we take a careful look at Church history and the teaching of the early Christians, it becomes clear that what we see today as speaking in tongues is actually a fairly recent development. The so-called “restoration” of ecstatic tongues really only began in the early 1900s, especially with events like the Azusa Street Revival. For almost 1,900 years before that, the historic Church neither practiced nor recognized ecstatic vocalizations as a regular part of Christian life.

In many modern charismatic settings, what’s happening actually lines up with what the medieval Church called prelest (a translation of the Greek word planē), a word that literally means “wandering” or “going astray.” Prelest is when someone confuses a false spiritual experience for a genuine one, often because of spiritual pride, strong emotions, or a deep desire for something supernatural. When we examine the modern practice of tongues in light of history, scripture, and the early Christian emphasis on spiritual watchfulness, it just doesn’t match up with the original apostolic gift. Instead, it seems to be more of a psychological imitation—something the Church has always warned believers to be careful about.

The Historical Reality of the Apostolic Gift

To evaluate the modern practice, it is necessary to establish the nature of the original, biblical gift of tongues. The foundational text for this phenomenon is the Day of Pentecost, described in the second chapter of Acts. Luke records, “And they were all filled with the Holy Spirit, and they began to speak in other languages, just as the Spirit granted them to utter.”

It’s important to notice that these were real, existing human languages. Just a few verses later, the crowd is surprised because everyone hears the apostles speaking in their own native language. The Greek word used here is dialektos, which is where we get our word “dialect.” This makes it clear that the apostles were actually using real grammar and vocabulary, not simply making ecstatic or unintelligible sounds.

Glossolalia in the Book of Acts is depicted as a group phenomenon that played a foundational role in the early Church, rather than as an individual spiritual experience.¹ The gift of languages provided a highly functional, cognitive tool for evangelism. Once the Church had spread globally and possessed speakers of every tongue, the miraculous provision of unlearned languages naturally ceased. St. Augustine explicitly taught that the gift was a temporary sign for the apostolic era, meant to demonstrate that the Church would eventually speak all the languages of the nations, and he noted that the phenomenon had entirely disappeared by his own time.²

Dismantling the Pentecostal Prooftexts

Because the historic Church didn’t practice ecstatic vocalizations, modern supporters of tongues often turn to a few verses from Paul’s letters to support their practice. However, when we look at these passages in the original Greek and consider their historical context, the argument for modern glossolalia becomes much less convincing.

Pentecostals frequently point to Paul’s words in 1 Corinthians 13 and 14 to argue for a private, heavenly prayer language. Chapter 13 and verse 1, for example, reads, “If I speak with the languages of humans and of angels, but do not have love, I have become a noisy gong or a clanging cymbal.”

Some Charismatics take this verse as permission to speak in a heavenly language that no one else can understand. But Paul isn’t actually listing out real angelic languages here. As St. John Chrysostom pointed out, Paul is using exaggeration to make a point, much like when we say, “If I’ve told you a million times...” Even if someone could speak in the language of angels, Paul’s point is that it doesn’t matter at all without love. So this passage isn’t encouraging believers to seek out non-human speech as a sign of spiritual maturity.

Coming to 1 Corinthians 14:2, which Charismatics use to defend the idea that tongues are a private prayer language meant exclusively for God’s ears: “For the one speaking in a language does not speak to humans but to God, for no one hears, but in the spirit he speaks mysteries.”

To really understand this verse, we need to look at what was happening in Corinth. Paul was addressing a complicated situation in a city that saw a lot of travelers and different languages. If someone came to a Greek-speaking church and started speaking fluent Persian, nobody else would know what was being said, so only God would understand. The Greek word for “understands” here is akouei, which simply means “hears” or “comprehends.” Paul’s main point is that speaking in a language nobody understands doesn’t help anyone in worship. He isn’t encouraging ecstatic speech; instead, he wants everything in church to be clear and understandable.

Perhaps the most dangerous theological error in the charismatic movement is the celebration of bypassing the intellect. Practitioners often cite 1 Corinthians 14:14 to claim their spirit is praying directly to God while their mind gets out of the way. “For if I pray in a language, my spirit prays, but my mind is unfruitful.”

In the tradition of historic Christian theology, having an unfruitful mind (the Greek word is nous) is actually seen as a dangerous place to be. Ignoring the need for a watchful, engaged intellect leaves a believer open to spiritual confusion. Paul isn’t endorsing an unfruitful mind in this passage; he’s actually warning against it. Right after mentioning it, he corrects the idea by saying, “I will pray with the spirit, but I will pray with the mind also; I will sing praise with the spirit, but I will sing praise with the mind also.” The intellect is meant to stay active and alert. States of mind that shut down rational thought and allow for uncontrolled vocalizations are more in line with pagan practices than with historic Christian prayer.

Romans 8:26 is occasionally cited to justify wordless vocalizations as a form of deep spiritual intercession, though this occurs less frequently. Paul writes, “...but the Spirit himself intercedes for us with unspoken groanings.”

The text makes it clear that it’s the Holy Spirit who groans, not the believer. The word used for these groanings is alaletois, which means “unspoken” or “unutterable.” Modern glossolalia, on the other hand, is something that’s spoken out loud. The quiet, internal prayer of the Holy Spirit in a believer’s heart is very different from the outward, vocal practices seen in many charismatic settings today.

The Anatomy of Modern Delusion

The main theological idea behind the Pentecostal approach is often called the “second blessing” doctrine. This teaching separates the moment of salvation from the reception of the Holy Spirit, while historic Christianity has always kept these two together. In the traditional view, the Holy Spirit is fully received at Christian initiation through Baptism and Chrismation (or Confirmation), and there’s no need for any later ecstatic “proof” to show that someone is truly filled with the Spirit. When a two-tier system is set up among Christians, it can lead to spiritual pride or anxiety, pushing believers to chase after a sign that was never required in the first place.

This pursuit often leads to emotionalism. Traditional Christian worship has always aimed to foster a deep, steady peace and spiritual watchfulness, which the early Christians called nepsis. In contrast, modern glossolalia often depends on a highly emotional atmosphere. The early Desert Fathers and other historic Christian teachers warned again and again about the dangers of stirring up intense emotions. They knew how easy it is for people to mistake physical or psychological excitement for the grace of God.

According to William J. Samarin, linguistic research indicates that glossolalia involves speech that is not associated with pathological or dissociative behavior, and often consists of spontaneous and “meaningless” utterances that do not form actual supernatural languages. The sounds used by speakers are shaped by their existing language patterns. What’s more, similar behaviors (like non-cognitive vocalizations and trance states) have been seen in pagan and occult traditions outside Christianity. Setting aside rational thought doesn’t bring someone closer to God in prayer; instead, it can open the door to psychological manipulation and real spiritual danger.³

There are some modern reports of real linguistic miracles, where people speaking different native languages are able to understand each other perfectly. Even when these stories are verified, they look a lot like the kind of functional, understandable miracle we see in Acts 2. These events involve real communication and connection between people, which is very different from the non-cognitive, ecstatic vocalizations that are often promoted in charismatic circles today.

Conclusion

Modern glossolalia doesn’t fit the biblical or historical pattern. It doesn’t match the apostolic gift of real, structured languages that were used for sharing the Gospel. It also goes against the writings of the early Church Fathers, who taught that this particular gift had come to an end.

When believers are encouraged to set aside rational thought, ignore traditional sacramental teaching, chase after intense emotional experiences, and overlook the historic Christian practice of spiritual watchfulness, the result is often spiritual confusion. Instead, Christians are better off seeking the quiet, repentant life that historic Christianity has always encouraged. Depending on sober prayer, an active mind, and the traditional means of grace is a much safer and more reliable path than pursuing ecstatic experiences that can lead to confusion.
