What does the Bible say about speaking in tongues?

In 1 Corinthians 14, we see that speaking in tongues was a gift present in the early church, particularly in Corinth, where some members could communicate in different languages. However, Scripture makes it clear that this gift was specific to the early church and tied to the apostles, whose authority was required to pass on the gift. Once the apostles died, there was no one left to transfer this gift. Thus, for modern believers, the absence of this gift aligns with the belief that we now possess the full canon of Scripture, rendering certain earlier practices unnecessary. Therefore, today's claims of speaking in tongues lack biblical support and should be approached with discernment.
