I went back through the thread, just to make sure; Aaron has set up a straw man argument.
The OP asked, is there a time to dance? Aaron's response, starting on page 3, centers around dancing in the temple or the synagogue, and focuses on the times that the people came together to hear the reading of the law. Up to that point, no one had mentioned dancing in church.
First, worship is not limited to the time(s) the people came together to hear the law, and the scriptures. Worship, as exemplified by David, and which we should do, is an "all the time, anywhere" kind of thing.
Second, the OP asked when is there a time to dance; so Aaron skirts the OP by answering when you should not.
Yes, I'm an independent fundamental baptist; but a long time ago I saw the passage that said David, a man after God's own heart, leaped and shouted and otherwise embarrassed his wife in total recognition of the mighty works that God had done. (so those of you that keep talking about how badly you dance, just remember: David's "embarrassing" dancing was recorded in scripture, so you can't really use that as an excuse!)
I can find fault in "dirty dancing," or dancing for the reason of finding someone to hook up with; but I can find no fault in dancing for worship of Him, nor in celebration of those things that God has given us (e.g., a spouse).
