Speaking is tongue is generally thought of as the Holy Spirit speaking through you. It's complete gibberish when it comes out, and there's no way for it to be interpreted or coded, unless another is also moved by God to translate, essentially.

I was never sure what I thought about it until my mom did it. I mean, I believed in it but I cant say I believe everyone who does it. But my mom was at some women's retreat thing, and praying with a group and she started to say "This is weird" but when she opened her mouth all this gibberish came out. So think of it what you will, gibberish hysteria or the Holy Spirit, I believe the latter.

Though I would have made this in EoEo, its gonna be a spam fest here.
