Our fundamental premise was to treat the worship as directed at the gathered community of LTS, not some hypothetical church. The two worships planned could not be transplanted anywhere else, but directed and speaking specifically to those who fill our pews in Santee Chapel.
Tuesday was built to be really uncomfortable... I wanted people so uncomfortable that they were puking in the pews. This didn't quite happen, but it did generate a lot of conversation. Namely "What is Worship?" The problem with this approach, as Julia rightly pointed out, is that it wasn't very careful in drawing people in. We just hit people over the head right away and defenses went right up. She then asked "What is the difference between Worship and a performance?"
Great question!

My worship teacher Donna Allen stated that worship is "an intentional encounter with the divine." i like that idea, and i'll build off of it.
My definition of worship is "A Social Articulation that is Horizontal and Vertical."
What I did find was that my definition works for me. It fits with my idea of God. I think that rarely do we see God operating in the present, we usually see God in hindsight. Like Jacob’s words, “God was in this place and I wasn’t aware of it.” Like Exodus 33:23, “…you will see where I just was.” We need to stop and recognize that God was in our midst and is still in our midst. Worship gives us that stop, that articulation, not only to find out what’s going on in our lives, but where God is active and working.
then i see this video by Brian McLaren:
so maybe it's not a performance... per se.. but a "corporate reaching for truth." where a gathered community (Ekklēsía if you will) tries to name a part of their reality. it utilizes elements of performance to try to name what is happening "on the ground" and yet name the transcendent reality.. the meaning as well. Christians try to use the framework of what was presented through the gospels, namely the framework and view of God as presented by Jesus of Nazareth. Like Paul stated in Romans 12:2 "Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is—his good, pleasing and perfect will." Maybe worship could best be defined like this, a testing? Or maybe as Eric Elnes puts it "I regularly meet my God, my neighbor, and myself through “the Jesus of history” or “the Christ of faith”" Check out his post "Who is Jesus For Me?" Could that be a definition?
I am no longer certain of where the line is between worship and performance? Is there one? What are your thoughts?
