'Language' in the Bible
When I came to you, brothers, I didn't come and tell you about God's secret with rhetorical language or wisdom.
And my language and my message were not set forth in persuasive (enticing and plausible) words of wisdom, but they were in demonstration of the [Holy] Spirit and power [ a proof by the Spirit and power of God, operating on me and stirring in the minds of my hearers the most holy emotions and thus persuading them],
And we are setting these truths forth in words not taught by human wisdom but taught by the [Holy] Spirit, combining and interpreting spiritual truths with spiritual language [to those who possess the Holy Spirit].
But the sense of my letter was that if a brother had the name of being one who went after the desires of the flesh, or had the desire for other people's property, or was in the way of using violent language, or being the worse for drink, or took by force what was not his, you might not keep company with such a one, or take food with him.
Or is a thief, or the worse for drink, or makes use of strong language, or takes by force what is not his, will have any part in the kingdom of God.
When I was a child, I made use of a child's language, I had a child's feelings and a child's thoughts: now that I am a man, I have put away the things of a child.
For the person who speaks in [another] language is not speaking to men but to God, since no one understands him; however, he speaks mysteries in the Spirit.
The person who speaks in [another] language builds himself up, but he who prophesies builds up the church.
Now I wish that all of you could speak in foreign languages, but especially that you could prophesy. The person who prophesies is more important than the person who speaks in a foreign language, unless he interprets it so that the church may be built up.
In the same way, unless you speak an intelligible message with your language, how will anyone know what is being said? You'll be talking into the air!
There are, we will suppose, a great number of languages in the world, and no creature is without a language.
Therefore, if I do not know the meaning of the language, I will be a foreigner = in Eng a barbarian. To a Gk, a barbaros was anyone who did not speak Gk. to the speaker, and the speaker will be a foreigner to me.
Therefore the person who speaks in [another] language should pray that he can interpret.
For if I pray in [another] language, my spirit prays, but my understanding is unfruitful.
yet in the church I would rather speak five words with my understanding, in order to teach others also, than 10,000 words in [another] language.
In the law it is written: "By those who speak a foreign language and by the lips of others I will speak to this people, and not even in this way will they obey me," says the Lord.
How is it then, brothers? Whenever you come together, each one has a psalm, a teaching, a revelation, [another] language, or an interpretation. All things must be done for edification.
