I'll take David's example as sufficient for the purpose of proving that dancing is acceptable in the eyes of God, except in the Temple, since there is no biblical record of dancing in the Temple.
And since, according to you, there is no earthly authority besides Scripture, we're at an impasse.
Or maybe we should look to the Church to settle our disagreement, as Scripture instructs us.
However, none of that has to do anything with what God might satisfy Himself with concerning dancing.
But first, a question, are you trying to shift the discussion over to "holy ground" perhaps?
If so I don't go there. Too many people ready to make war over the concept, and places they think to be especially "sacred". Lot of bad ju-ju in that discussion.
