In Paul's day pagans (e. g. Greek oracles) speak in tongues (gibberish) in order to have it interpreted. You can cite no example iin Paul's day of any pagan speaking in private tongues. And even if they did, so what? Private tongues raise the purity and passion of our praise to God and Jesus.
No it doesn't, because you do not know what that tongue for private use is doing as you all claim that it can be for self edification, supposedly the Holy Spirit praying to God, and now to raise purity and passion of your praise to God & Jesus.
Paul himself refute you claim by celebrating the edifying value of private prayer tongues:
"He who speaks in tongues edifies himself (1 Cor. 14:4)."
Paul said so in context of comparing tongues against prophesy for why prophesy is better; not how cool it is by itself when that same tongue needs to be interpreted to be understood by the tongue speaker so the tongue will be fruitful to himself, therefore never intended for private use.
Paul wants believers to pray in tongues at home or, at least, not in a public meeting where outsiders are present: "But if there is no interpreter, let him be silent in church, but speak [in tongues] to himself and to God (14:28)."
That verse you had quoted refutes your application, brother, when you remove the bracketed words [ in tongues] which was added & inserted.
"
But if there is no interpreter, let him be silent in church, but speak to himself and to God (14:28)."
27 If any man speak in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret.28 But if there be no interpreter, let him keep silence in the church;
and let him speak to himself, and to God. KJV
Read plainly like that requires discernment because people talking to themselves can be seen as a crazy person and so therefore Paul is saying when there is no interpretation, then it is a visiting foreigner speaking out of turn when you have one by one, of 2 or 3 speaking in tongues while another interpret in church service. The man is not speaking in tongues for why he is commanded to be silent in church as he was speaking out of turn, understanding what he is saying as God does because it is not God's gift of tongues.
That is how you understand the meaning in 1 Corinthians 14:2 about God's gift of tongues is one where the speaker does not understand it, albeit he speaks in mysteries, but God does. verse 2 is not conveying the tongue speaker is speaking TO God because there are no mysteries TO God.
Follow after charity, and
desire spiritual gifts, but rather that ye may prophesy. 2 For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries.
That is Paul explaining why in being zealous for spiritual gifts to seek the gift of prophesy over all spiritual gifts as stated in verse 1 and he began to compare tongues against prophesy to show why prophesy is better because prophesy is a stand alone gift whereas tongues is not, needing interpretation. To be read any other way to mean tongues are for private use is ignoring the context of the message of what Paul is conveying, otherwise look at what you all are doing! Exalting tongues over prophesy to seek after as the complete opposite of Paul's exhortation!
If no outsiders are present, Paul approves of uninterpreted prayer tongues spoken in a group (Acts 19:6).
When Paul having passed through the upper coasts, had come to Ephesus? Sounds like he was outside in public to me in coming across those certain disciples.
Acts 19:1And it came to pass, that, while Apollos was at Corinth, Paul having passed through the upper coasts came to Ephesus: and finding certain disciples, that were disciples of John the Baptist's for why Paul told them about Jesus, then they got water baptized in His name and were saved, speaking in tongues as God was manifesting to speak unto the people around them in public.
You do not have Paul finding certain disciples, not knowing for sure what kind of disciples they were unless travelling in Ephesus when he came across them in "finding" them in public.
Paul wants every believer to pray privately in tongues and boasts that he does this all the time:
"I want you all to speak in tongues...I thank God that I speak in tongues more than all of you (14:5, 18)."
He said speak in tongues here, not pray in tongues.
So Christ4Me, why are risking blaspheming against the Holy Spirit by opposing a gift that He wants to give you for self-edification?
Why are you overlooking the fact that the Holy Spirit can remind you of His words in English by bringing into remembrance all that Jesus has said?
John 14:26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
What need is there for self edification by tongues for private use because when uninterpreted, you cannot know if you are being self edified or the Holy Spirit supposedly praying or for some reason the Holy Spirit decides that it was time to give praise & passion in worshiping God?
Like it or not, God wants genuine worship, normal prayers, and thanksgiving for answers to known normal prayers coming from us rather than in confusion since you cannot know not what that tongue is doing therefore it is not of Him at all. I remind you God is not the author of confusion in any church of the saints for why we are to test the spirits and the tongues they bring per 1 John 4:1-6.
1 Corinthians 14:32 And the spirits of the prophets are subject to the prophets. 33 For God is not the author of confusion, but of peace, as in all churches of the saints.
