Glenn Packiam, a former worship leader turned Pastor, loosely defined liturgy as any activities done by a group regularly.
For example, a Panthers game has a liturgy. You expect to tailgate, you expect to wait in a long line to get in, you expect to yell "first down" many times, to stand up and shout and yell. These things are the liturgy of a football game.
If you tried out this liturgy at the mall people would look at you like you are crazy. It's a different setting, a different cultural liturgy.
Glenn's point, that has set my mind in motion, is that we (the church) have borrowed liturgies from the world. Part of this is inevitable, I suppose. We are trying to reach people in our culture, so we have to speak the language.
But Glenn said that in our worship, we have at times borrowed a rock concert liturgy and then we are surprised that it produces the result that it's supposed to. We shouldn't be surprised when we borrow a liturgy that is DESIGNED to turn people into consumers and see that people consume the music as a product built for them to enjoy.
What can we do to keep speaking the language of our culture and still lead people towards a worship that puts God at the center instead of ourselves, instead of our own needs and consumption?
Still wrestling with these questions. More thoughts to come, I'm sure. But you should watch the video if you have time, I'm trying to summarize an hour in a very short post.
