IS BIBLICAL SPEAKING IN TONGUES SUPPOSED TO BE GIBBERISH? Gibberish is a false form of speaking in tongues and it is just another phony teaching infiltrating the Christian Church today. If it is going to be a true gift of the Holy Spirit, which is itself a debate about whether those gifts are still even functioning for Christians today, it has to be a known language. I didn't say that; it comes from the Bible in Acts 2 about when the tongues went forth. There, the word is "glossolalia" in the Greek, meaning "languages." So, biblical speaking in tongues was specific languages and not gibberish. The people in Acts 2 heard the tongues in their own languages.
