Hello fellow Ex-UPC'er!
There is. I like to refer to speaking in tongues as a "jazz mantra."
Yep. It's part of the "raising the energy" cycle in ritual forms which always follow this form:
1. Close the circle (create the space)
2. Raise the energy
3. Do the work
4. Ground the energy
5. Open the circle (re-enter the world )
This natural order is seen in group ritual in everything from church services to baseball games.
Admittedly, that is an appealing thing that I miss from those days back in the UPC. But there is no way I could lobotomize my intellectual mind enough in order to build a community with those whose beliefs are so... well, tribal.
Of course it's not. I even thought that was a really dumb interpretation on their part, that you have to speak in tongues as a demonstration you were saved. Even in my naive youth, I wasn't that out of touch with reason to imagine that could really be true.
