Doesn't seem to have anything at all to do with his dancing either ~
Uh, yes it does. Forgive me, but I assumed you had some knowledge of the passage in question. Go here to read the whole thing:
http://www.drbo.org/chapter/10006.htm
But, back to the point, David danced.
Yes. And my point was that by dancing before the Ark, he did poorly. It was an indication of how haughty, arrogant, and sexually profligate he was already becoming.
I think what we have are two different situations to discuss. One is this business of dancing in an RC church. Another is whether or not dancing is reported in the Bible to have ever occurred in a religious context.
That it occurred is not in dispute. The point is, it was not a good thing. Similarly, there is no tradition of dance within the early Christian Church. If you can produce concrete evidence that the Syro-Malabar rite of the 1st through 4th centuries AD included dance, then by all means, do so. Otherwise, you're just operating from assumptions.
