Where did you get that the church bans dancing??? However... the church is the bride of Christ, as members of the church we are to be a reflection of Christ here on Earth. Kind of like the bumper sticker says, "What would Jesus do". We try to avoid doing anything that would be a bad reflection on Christ. So we should all as Christians look at every situation with the thought 'what would Christ have me do'. I just don't think we would have ever found Jesus doing the Bump and Grind.
Personally, I don't think he would be apposed to the hokie-pokie, but that's just me.
