Being told as a child that the Bible "tells us how to live" caused me

After many years as a Christian, I finally asked and got my answer.
There are many different kinds of dancing. The relatively recent prohibition on dancing may have been established as a reaction to couples dancing, in which men and women dance together one-on-one in close contact. (The waltz was considered shocking by many when it first came out.) Such intimacy between unmarried people can lead to sin. To guard against temptation, a rule is made, and the rule is simplified to "No dancing." All forms of dancing have suffered as a result. This is a example of how Biblical principles can be developed into a cultural taboo.
But given the culture of the time, it was OK for King David to dance in celebration of the return of the ark of the LORD. <PrudeMode=On> Personally, though, I think he ought to have been more modestly clothed. :-)
