I have been thinking the same thing recently. Not only should the structure/form of the church emerge out of those in it, but the worship too should come from those involved. Thus we don't rely on the newest worship songs out there (nor the oldest ones) to facilitate our worship but we bring the ways we worship God to the community (which indeed may be those worship songs but I hope there are many more ways also), creating a unique expression of worship. Unique in the sense that it emanates from the gifts God has given specifically to us to return to him.
"What Christians need to do is create meaningful worship through bringing their very own lives to God. Worship must reflect the culture of the community that is currently part of the church, not replicate current worship CDs, nor 1980s soft rock, nor 18th century hymns. Instead of mimicking other church cultures, the community collectively brings their own idiosyncratic ways of life to God, whatever they may be."
Bolger continues by pointing out that evangelism is not brining people to church, but is being missional, going to the 'them,' presenting Christ in everyday life and not in our evangelical sub-culture.
Bolger goes on to note that by focusing on the Church services as the core of what church is simply perpetuates the the mythical secular/sacred divide, it perpetuates the laity/clergy split (implying that only those paid for ministry do it), and it perpetuates a producer/consumer faith.
Bolger finishes up by presenting some alternatives.
This post was great, in my mind, at distinguishing the main differences between the seeker sensitive models of church and the emerging/organic model we are finding ourselves in conversation with. In other words, it helps explain why the picture below is a bit confusing.
