Rich Leonardi handily predicts that a bishop’s pastoral visit to Africa will result in commentary praising liturgical dancing. Then he posts a picture of silly American liturgical dancers.
Just because liturgical dance is silly here doesn’t mean it isn’t good in other places. Conversely, the existence of truly worshipful liturgical dance in other countries, if it indeed exists, does not make it a good idea in American parishes (except maybe those composed largely of immigrants from places of the former type).
Liturgical dance done here doesn’t spring from the heart of our culture as a genuine act of worship. It’s imposed on us.
That’s a big difference.
Nor do we recognize any kind of body motions that we could call "dance" as signifying any sacredness.
And it’s not because "the church recognize[s]" that "people were going to move their body and that was going to lead them into sin," as someone said once, and as Rich quotes them in another post.
We do have body motions that we recognize as sacred or that we invest with meaning. You can tell their authenticity in our cultural context by seeing where they are copied, outside of church, by people wanting to import an air of the sacred.
Think of the solemn procession (much used in civil ceremonies, graduations, etc). Think of the sign of the cross and its resemblance to, say, placing your hand over your heart to honor the flag. Think of the ringing of bells. Or rising from your seat in the presence of a respected person.
These aren’t cultural signifiers of the sacred because they are used in church. They are used in church because they signify the sacred.
