This was a question asked me by one who prayed in ‘tongues’ during Church service, and his Pastor called him down for it. In order for me to properly answer that question, I would need to know more about how that individual meant ‘tongues’; other languages such as, Spanish, German, etc., or the ‘unknown tongue’ which few can understand today.

     Secondly, Paul stated in I Cor. 14, “For God is not the author of confusion, but of peace, as in all churches of the saints.” In that Chapter you’ll find the proper instructions to the Church for conducting service, which is teaching The Word of God. Anything that disrupts the teaching of God’s Word in Church is not to be allowed. I Timothy also gives instructions for Church doctrine and conducting behavior in the Church.
The common sense of the matter is similar to when we were in school, if another kid in class started doing something which disrupted the other students from learning, even including provocative dress by the females in the class causing distraction, then the teacher would take control, which also the authority of a Pastor teaching in Church has, as given by God.
There is a deeper message which you may or may not receive, as long as you know that I am trying to help, but if you have doubts about what I’m going to say, then I challenge you to dig in The Word for yourself, and make your own decision. Before you read the following paragraphs, I strongly recommend you ‘study’, not just read, the following verses and Chapters: Acts 2; compare Matthew 24; Mark 13 with Rev. 6.  Also study 2 Thessalonians 2 documenting that the ‘son of perdition’ must first be revealed, who is Satan himself; 2 Corinthians 11; I Cor. 14; and Ezekiel 13 dealing with the “secret rapture” “fly away” doctrine. By the word ‘study’ I mean to do it for yourself, don’t ask me or anyone else to interpret it for you, and it must be done in prayer to Jehovah through His Son Jesus Christ for guidance.
My position on the ‘unknown tongue’, of which I have several friends who do speak in this ‘unknown tongue’, I do not, is according to God’s Word in Acts 2. It is written there in Acts that the ‘cloven tongue’ spoken on that Pentecost day was known languages of the world, going out in all directions, and every man heard in their own language, and even ‘dialect’ from the country in which they were born. This is not the same ‘tongue’ which my other Christian friends speak, because none that I’ve been around can understand when it is spoken. Therefore, until everyone present understands those of today who speak in an ‘unknown tongue’, in their own language and even in their dialect of birth (English, Spanish, etc.), then, it is not the true tongue the Apostles spoke on Pentecost day, according to Acts 2 (see the Tongues study). Further, the word ‘unknown’ in I Cor.14 in the KJV was added by the KJV translators. It is not in the original Greek Manuscripts. That word ‘tongue’ there is ‘glossa’ in the Greek, meaning “a language, one naturaly unaquired” (Strong’s no. 1100).Paul was teaching there in I Cor. 14 about how to conduct the edifying of God’s Church making prophesying (teaching) the most important function during Church service. Even the true meaning of the word ‘prophesy’ has been twisted by those who speak an unrecognizable ‘unknown tongue’.  To ‘prophesy’ means to ‘teach’ with words of understanding. Since Paul was a Hebrew Biblical scholar, previously being a Pharisee, and trained under one the greatest Hebrew Biblical scholars of his day named Gamliel, naturally then, Paul spoke other ‘tongues’, such as Hebrew, Aramaic, and of course Greek.

    The following verses point out ‘languages’ as being the whole matter, not the ‘unknown tongue’ which few can understand.

1 Cor 14:9     So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye shall speak into the air. 1 Cor 14:15    What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also.

1 Cor 14:19    Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, than ten thousand words in an unknown tongue.

1 Cor 14:26    How is it then, brethren? when ye come together, every one of you hath a psalm, hath a doctrine, hath a tongue, hath a revelation, hath an interpretation. Let all things be done unto edifying.

1 Cor 14:33    For God is not the author of confusion, but of peace, as in all churches of the saints.(KJV)

FINALLY:  If the ‘unknown tongue’ is a ‘sign’ for those who will speak with God’s Holy Spirit against Satan’s New World Order Religious organization, now in the final process of being set up in the world as I speak, then all that hear that ‘tongue’ must be able to understand in their own dialect of the country’s language where they are from. That has not happened yet. So I’m not judging you, nor any man, as I don’t have that authority or right. As I stated before, it is amazing that some friends who do speak in this ‘unknown tongue’ also believe they are going to ‘fly away’ with the first Messiah, which will be Satan playing the role he has always coveted by his pride, the role of the Savior of the world. There is only One Son of God and His Name is ‘Immanuel in the Hebrew meaning “God with us”, Wonderful, Counsellor, The Mighty God’ (Isaiah 8:8 and Isaiah 9:6) ‘Jesus Christ’ (Christos meaning ‘Anointed, Messiah’), Iesous in the Greek, Yashua in the Hebrew meaning “Jehovah is salvation”.
