What God
could do is not in question, what God does do is another thing all together.
Simply saying "God could..." doesn't mean God has given some 'gift in a heavenly language'. In 1 Cor 13:1 Paul is not claiming that there is a "tongue of angels" that people can speak in, he's using the phrase as hyperbole in contrast with not having love. No where else does Paul speak of such a thing being possible.
The tongues spoken of in Acts 2 are clearly human languages. They're given for a very distinct purpose which we see in that same chapter, namely, to announce that the Messiah has come and salvation is available through Him, AND that the Jews missed the boat.
How so? Let me show you.
Most charismatics dwell on three chapters in 1 Corinthians to provide support for their claims. Let's keep in mind however that 1 Corinthians was written not as a tongue-speaking manual, but a letter of correction to a church with many, many problems. The church in Corinth had a member who was involved with his father's wife, they were not taking care of their members, people were speaking out of turn in the service... in essense they were a good representative picture of the modern non-denom/charismatic church in America.
Let's find out what Paul says the PURPOSE of tongues is:
1 Cor 14:21-22
In the Law it is written, "BY MEN OF STRANGE TONGUES AND BY THE LIPS OF STRANGERS I WILL SPEAK TO THIS PEOPLE, AND EVEN SO THEY WILL NOT LISTEN TO ME," says the Lord.
So then tongues are for a sign, not to those who believe but to unbelievers; but prophecy is for a sign, not to unbelievers but to those who believe.
Here Paul expresses the purpose of tongues, "a sign... to unbelievers". Paul quotes Isaiah as support for this fact. Paul is quoting the Septuagint, the Greek translation of the Hebrew Scriptures. The verse in our Bible today says:
Isaiah 28:11
Indeed, He will speak to this people through stammering lips and a foreign tongue,
It is important to recognize here that in both cases tongues is not some 'angelic language'. Consider for a moment that no two charismatics speak in the same "tongue", can this be the "tongues of angels"? Does every angel speaks in a different language?!
Note that the purpose of tongues, both in 1 Cornithians and in the prophecy, is to "speak to this people" in "a foreign tongue". We see this occuring clearly in Acts 2, where it is lowly fishermen speaking in the languages of people from all over the world. It's imperitive that we seek to harmonize 1 Corinthians and Acts, rather than suggesting they're referring to different gifts.
This is a message to the Jews that they're under judgment, the Messiah came folks, and you killed Him!
Thus Paul writes that tongues is a
sign to unbelievers.
"What about 1 Cor 14:2!?" I hear someone say...
1 Cor 14:2
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.
Again, keeping the PURPOSE of tongues in view here, we must consider what this verse means. Who were the men in Acts 2 speaking
to?
Acts 2:8-11
"And how is it that we each hear them in our own language to which we were born? Parthians and Medes and Elamites, and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, Phrygia and Pamphylia, Egypt and the districts of Libya around Cyrene, and visitors from Rome, both Jews and proselytes, Cretans and Arabs--we hear them in our own tongues speaking of the mighty deeds of God."
The men in Acts 2 were "speaking of the mighty deeds of God", that is they were
praising God. Tongues then is a praise language (as opposed to a prayer language) and it is not meant for personal prayer, but as a public declaration of the deeds of God, just as 1 Cor 14:2 states.
It is apparent then that
"this people" spoken of in Isaiah and fulfilled in Acts and elsewhere is none other than the Jews of the first century. The Biblical declared purpose of tongues is to announce judgment on the 1st Century Jews, which since the destruction of the temple are long since past.
Finally, it is God's command that there be no tongues without interpetation in the church. Paul is very clear on this.
19however, in the church I desire to speak five words with my mind so that I may instruct others also, rather than ten thousand words in a tongue.
27If anyone speaks in a tongue, it should be by two or at the most three, and each in turn, and one must interpret;
28but if there is no interpreter, he must keep silent in the church; and let him speak to himself and to God.
37If anyone thinks he is a prophet or spiritual, let him recognize that the things which I write to you are the Lord's commandment.
38But if anyone does not recognize this, he is not recognized.
So even if you dismiss the whole "tongues was a sign for unbelievers", the common practice of mass singing in tongues, or even the outbreak of tongues by vocal women in the first row (1 Cor 14:34 instructs us about those ladies
) is not allowed in Scripture. How many churches who pratice tongue-speaking actually follow God's commands relating to it?
Eagerly desire the greater gifts... the greatest of these is love.
