I beg to differ. Please re-read and re-study I Co 14, especially verse 6 which is the key verse. When you have understood this verse, you might understand the phenomenon of tongues.
And if you still have not gotten the gist of the mystery and meaning of tongues, I'll gladly expound it for you.
At the meantime, it is best to do your own homework instead of relying on someone else's
teaching. This is the reason why there are so many different denominations in the world because of wrong interpretations!
To God Be The Glory
You haven't answered the question of Paul saying, "I thank God I speak in tongues more than you all", and "I would that you all speak in tongues". If the speaking of tongues is confined to church meetings, and Paul instructs not to speak out loud in tongues during church meetings, wouldn't he be contradicting himself? And what about verse 2, where it says that speaking in tongues is speaking to God and that no man understands him. These statements of Paul clearly indicate that he often prayed in tongues privately, away from public church meetings.
If your exposition of 1 Corinthians 14 is based on just one "key" verse (6)., indicating that tongues is confined to church meetings, then you have to twist other verses to support your premise. It means that your premise is coming first and you are trying to shoe horn Scripture to fit into it, rather than forming a premise based on what Paul is actually saying.
My practice of the gift is not based on man's teaching at all. I quoted Calvin, who is a much better theologian than you or me and I wouldn't be so arrogant to say that he isn't. I have done a very comprehensive study of 1 Corinthians 14, and studied every single word of it, and so my views on tongues is based squarely on that chapter and what Paul is actually saying in it.
I think that after spending five years doing a B.A. and then an M.A. in literature, and another three years doing an M.Div, I think I know how to analyze literature, do exegesis, and have some idea of hermeneutics. So, unless you can match the expertise and experience I have gained, forget about trying to teach me what 1 Corinthians 14 says.
