I'm glad you made this post. It addresses a couple of important points.
I think first of all we have to separate worship from evangelism. Then, in evangelism, I can see God using attractive means to draw some to the gospel, but never in a way that is dishonoring to his holiness.
I am not sure the two can be completely bifurcated. After all, Paul commends the idea that our worship will lead to evangelism. We are both agreed that God's holiness (or any other attribute) should not be violated.
And where do we draw the line between the appropriate and inappropriate? I don't know, all I can do is protest when my nose tells me something stinks. The problem is that Warrenites REFUSE correction from those of us that might have exercised our senses to discern good and evil longer than they have.
This statement almost makes me laugh. I am not sure you even recognize the arrogance of what you wrote. 1. The line of appropriate & inappropriate is subjective ("I don't know"). 2. You are the determiner of what is right and evil (or perhaps I should say your nose is the determiner). 3. "Warrenites" should be corrected by those who have better discernment (those who are the determiners of what is right and wrong).
Can you even recognize the arrogance and insult of a statement like this?
Also, we would get a lot of this controversy cleared away from our churches if we tried to practice the regulative principle, which says that NOTHING is permitted unless it is specifically established by the bible. It's challenger, the normative principle, says that ANYTHING that the bible does not specifically prohibit is permitted. Under the this philosophy, there is no argument against the outlandishness that goes on. Just put "christian" in front of anything, then it is "christian" - "christian" rock, "christian" mosh pits, "christian" tatoos, ad infinitum.
I have never found a person who practices the regulative principle with consistency. If you have pews, a pulpit, hymnals, a piano, an organ, A/C, a sound system, carpet, a parking lot, a building, a church sign, a nursery, a children's program, ad infinitim, then you are inconsistent in your practice of the regulative principle. None of these things are found in Scripture and they are all means and methods.
The issue is contextualization. More about that in a moment.
Also, it's important to remember that the emergent church, seeker-sensitive and such like, began as a sub-culture within the wider christian population. "All things to all people" has to do with relating within a culture, and has nothing to do with developing a sub-culture which features an open rebellion against the norms of the established culture.
Imagine if you will a missionary going into a foreign country, and there he adopts the ways of some subculture rather than relating the gospel to the wider audience. Would this be "all things to all people"? No, because it would be joining the force of a driving wedge between people. It would be "some things to some people". The very opposite of what it alleges itself to be.
Again this is almost amusing to read. Many of my emergent and seeker-sensitive friends would find it quite ironic that they have been identified as a subculture that is rebellious to the greater culture. I will only speak to the emergent movement at this point. The heart of the emergent movement rests on the idea of being missional within a culture.
Simply put, gospel + church + culture = missional.
Gospel + church - culture = fundamentalism
Gospel + culture - church = parachurch
Culture + church - gospel = liberalism
I am glad you use the missionary illustration becuase it is one of the best ones for the theology and philosophy behind the emergent church. Missional churches believe every believer is called to be a missionary within their given culture. We are not to retreat from culture and create a Christian subculture. We are to engage culture. We are to be students of our culture. We are to know their language, arts, stories, etc. This is called "contextualizing" the gospel (all things to all men). We recognize the call to contend for the faith within culture and we seek to strike a balance between contextualization and contending.
Missional thinking should transcend theological systems such as Calvinism, Arminianism, etc., but very few theological subcultures such as Calvinists seem to be able to strike the balance between contextualization and contending. They are so protective of their theological system that they are overprotective of their methodological implimentations. There is a group of emergents who are very Reformed and yet maintain a philosophy of ministry that is very progressive.
In recent weeks, discussions have surfaced in evangelical circles about issues like fire truck baptistries and other things that appear to be "over the top" attractional methods. I simply believe these means have to be considered in light of a contextualization. A fire truck baptistry may be appropriate within a certain context. What has been made clear in that discussion is that each child who is baptized is counseled more than once regarding their commitment to Christ. That being the case, the fire truck baptistry is merely a means of celebration that connects to a child. Contextualization.
I will stop for now because this post is getting too long. I would simply suggest that "all things to all men" has to do with contextualization which is one important element of being a missional church.
