So your saying that the following verses support Gentiles only speaking in tongues. To demonstrate to the
Jews that tongues are for the Jews only?
Acts 19:6
And when Paul had laid his hands upon them, the Holy Spirit came on them, and they began speaking
with tongues and prophesying. (disciples at Ephesus)
1 Corinthians 14
Pursue love, yet desire earnestly spiritual gifts, but especially that you may prophesy. For one who speaks
in a tongue does not speak to men but to God; for no one understands, but in his spirit he speaks mysteries.
1 Corinthians 14:39
Therefore, my brethren, desire earnestly to prophesy, and do not forbid to speak in tongues.
Paul is speaking to the next generation in the Corinthian church. Paul wrote this first letter to the Greeks
in the very late fifties. That refutes the idea that tongues were for the Jewish church only. Paul's letter to Corinth
warns the Gentiles not to forbid speaking in tongues. 1 Corinthians was addressed to a Gentile church.
Why would God command the Gentile church not to forbid speaking in tongues, twenty five years after
Pentecost?
Remember, tongues are not some jibberish speach, but actual languages. Let's start there.
Acts 19, I would say these are Jews since they are disciples of John the Baptist.
1 Corinthians 14 is about speaking in the language of the audience. It could best be summed up as the guidelines on how “tongues” should be used in the local assembly. Paul explains where the Corinthians are wrong in their approach to tongues and their use.
The term “unknown” is mentioned 6 times in this chapter. This term is a reference to a tongue that the speaker does not know, or the hearer does not know or understand.
There are three types of languages or "tongues" in scripture:
1. “New tongues” - Languages that are new, and the speaker has not learned them (Mk. 16:17).
2. “Other tongues” - Languages that are not the native tongue of the speaker (Acts 2:4; 1 Cor. 14:21), which he may have learned, and the hearer understands (1 Cor. 14:18).
3. “Unknown tongues” - These are languages that are unknown to everyone in the congregation, and need an interpreter (vs. 13, 27).
