So you think tongues are a problem that need a solution?
Paul is saying, 'speak intelligible words with your tongue', Paul is not saying, 'speak interpret-able words with your tongue'. IOW, Paul is saying speak a language that people can understand, that whole chapter, Paul insists on understanding and it's only through understanding that people are edified.
Tongues are not a problem. People not understanding them is the problem. I am not sure what your other point is. I am not sure what translation you are using, but 'speak intelligible words with your tongue' is a part of a sentence, which is a part of a larger thought. I'll use the KJV to show what I am talking about:
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.
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.
13
Wherefore let him that speaketh in an unknown tongue pray that he may interpret.
Paul's argument here leads up to verses 12 and 13. Notice his conclusion is not that they should not speak in tongues, but that the speaking in tongues needs to be interpreted. Look at verses 27-28 also.
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.
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.
We need to imagine the type of church meetings Paul is assuming the church has here, one in which regular members of the assembly sing and speak to edify one another. This is in line with Hebrews 10:24-25, which tells us not to forsake assembling, and also what to do when we assemble-- to 'exhort one another', in the context of provoking one another to love and to good works. Paul does not teach the church to have a 'spectator church' meeting where everyone sits and listens to one man give a long sermon, as we see in Protestant tradition. It is helpful to realize Paul's instructions are for a different type of church meeting from what many of us our used to, the type of meeting that has evolved through tradition.
After writing all that about speaking in tongues, Paul gives commands regarding the interpretation of tongues in church. Speaking in tongues and interpreting in the proper order is allowed in church. Prophesying is allowed and encourage, again, in accordance with the 'commandments of the Lord' for our church meetings in this passage. Later in the passage, Paul writes to covet to prophesy and to forbid not to speak with tongues.
To a Spanish congregation, speak Spanish, if you are going to speak another language then there must be at least two people in the congregation that have the gift to interpret it to Spanish for the benefit of others, otherwise shut up.
Two people have to interpret? In verse 27, Paul says 'and let one interpret.' I would take that to refer to the one ('tis') who speaks in tongues, not a restriction on someone else interpreting if another person receives a message in tongues.
All these things ceased in the 1st century, what we have today has nothing to do with God.
Where do you get that. My Bible tongues whether there be tongues, they shall cease, not that they ceased in the first century. As Paul started off this epistle in which he would write about tongues, prophecy, and other gifts, he wrote, 'So that ye come behind in no spiritual gift, waiting for the coming of our Lord Jesus Christ.' Why would he have written that if he envisioned a time before Jesus came back when the very gifts he was Jeus about to write about would cease? We should take Paul's hint here about the time-frame he has in mind.
Paul, when he wrote I Corinthians, was like a child in comparison to his speech, thoughts, and understanding, compared to what he these things will be like when the perfect comes. We are still learning from Paul today. We have not so far surpassed him that his writings seem like the works of small children.
