It certainly has become an interesting conversation. I think Mordos asks some good questions, and I think Icthus makes some good points.
The whole question of the place of culture in church/worship/faith is one that believers have wrestled with for centuries. And I think it's one that is central to our view of the mission of God in the world around us. Oftentimes in the middle of a message or study we'll hear something like, "Let's look at this in context. What did this message mean to the listeners of the day?" I believe that what that really means is, how did these words resonate to the Hebrew culture? They had a certain set of values, traditions, expectations, and understandings that gave this message a particular 'spin'...what was that?
I also think we need to look at how Jesus dealt with the culture around Him. Personally, I see Him directing His message directly into the culture of the day. Granted, I believe that Hebrew culture of the time had developed largely as a response to what God had done throughout their history, but we also see a significant part of that culture that didn't reflect God's intent, design, or plan. Jesus spoke and taught directly into that culture. He engaged the traditions of the Hebrews, told stories in ways that they could relate to culturally, and used their cultural context to reach out to people with His truth in ways that were relevant to the listeners.
I think we see a similar practice with modern missionaries, particularly those going into areas that haven't been exposed to the gospel yet. They go into a new culture and spend time getting to know the people, their language, their traditions, their beliefs, and their stories. They then begin to present the gospel to them in a culturally relevant context. Rather than just carrying along their King James Bibles and teaching in a traditional "Western church" context, they seek to make God's truth understandable and relevant to the listeners.
Personally, I don't see why we can't follow the same practice today in our culture. There are large areas of our culture that have a firmly established 'church tradition' that makes most people at least aware of and essentially familiar with the basics of Christianity. We have other areas of our culture, and I live right in the middle of one of those, that don't. The average person on the street in many areas has had no exposure whatsoever to Christianity aside from what they've seen of televangelists or some fanatic 'preaching at' them from some street corner. There's very little understanding of who God truly is or what His intent is in reaching out to humanity.
Given this lack in many areas, I think approaching these populations as a mission field is a very valid way to try to engage people for the purpose of presenting them with the gospel. Now, I want to draw a distinction here that I believe is vitally important. Much of the 'emergent church' movement is seeking to not only present 'church' in a culturally acceptable way, but also to redefine exactly what this 'gospel' is that they're presenting by watering down Biblical truth and altering the basic truths that God has revealed to people since creation. I am absolutely opposed to this, whether as a foundation for evangelism or for 'engaging culture'. God's truth is God's truth, period. It hasn't changed, it isn't changing, and it won't change. Those who try to change His message are no longer teaching His message, end of story.
Now, given that caveat, I have no problem with those who seek to take sound, biblical theology and combine it with culturally familiar music, dress, etc. There is much in modern culture that has no place in church, but when it comes to the 'feel of the environment', I personally don't think God cares whether we wear suits to church or wear shorts, sing traditional hymns versus contemporary worship songs, or teach about 'growing deeper in Christ' as opposed to teaching about 'sanctification'. I personally believe that God is infinitely more concerned with what's in our hearts than what's on our bodies.
Now, I realize that not everyone is interested in 'contemporizing' church. Many prefer hymns and tradition. That's fine. I've got no problem with doing things the way that they've been done for centuries - I just don't see any particular virtue for doing something just because it's how we've always done it (again, style, not theology...don't mess with doctrine!). I grew up in a traditional, fairly liturgical church environment, and personally prefer a more contemporary style of church, so I go to one of those now. I fully realize that many people would walk into my church and say, "Eh...I don't really like it." That's perfectly fine. Doesn't bother me a bit. I don't think any church can truly meet the preferences and needs of all people. If we try, we'll quickly find that we're meeting the preferences and needs of none.
Bottom line is that I think those seeking to take sound, biblical theology and introduce a culturally relevant environment to it are just fine, and have the potential to carry God's truth to people and places that just wouldn't listen otherwise. I also believe that those who prefer a more traditional approach are just as fine. The issue I have is when the latter stand in judgment of the former. God isn't limited in how He chooses to work. Sometimes we're comfortable with how He does things, sometimes we're not. Trying to limit Him to just what we like is treading dangerous ground. He gets to set limits on us, not vice versa.
