But how was he correcting them? He was not forbidding!
v7 And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped?
v9 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.
10 There are, it may be, so many kinds of voices in the world, and none of them is without signification.
11 Therefore if I know not the meaning of the voice, I shall be unto him that speaketh a barbarian, and he that speaketh shall be a barbarian unto me.
12
Even so ye, forasmuch as ye are zealous of spiritual gifts, seek that ye may excel to the edifying of the church.
v19 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.
20 Brethren, be not children in understanding
THAT is how he was correcting them. How can anyone not read those words and say, "you know what? I need to be really, really, *really* careful if I or someone else says they have the gift of tongues."
Speaking in tongues is the same throughout scripture. It is a language spoken by a believer that he does not understand. It is an utterance given by the HOly Spirit. It is speaking to God!
In Acts, please show scripture that says the speakers did not understand what they were saying.
Note that in 1 Cor 14:6, Paul says "
IF I come unto you speaking with tongues"; and in v14 "
IF I pray in an unknown tongue." Just like in 1 Cor 13, there's a reason to pay attention to every jot and every tittle. Because look at what Paul says in v15: "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."
Chapter 14 may wrap up with "forbid not"; but the context of chapter 14 is "edification of others." You can't edify others, or even yourself, if you have no idea what's being said.
Remember, in 1 Cor 12, Paul was telling them that not all have the gift of tongues; and if I read 1 Cor 12 correctly, I wouldn't want everyone to have the gift of tongues. So if everyone in your church is saying that they pray in tongues, whether when they're alone or elsewhere, then there's something wrong.
And with that, I withdraw from this conversation. It's gone on too long.
