Cultural Relevance -- Has the Church gone too far?

I guess what I'm looking for here is some thoughts and discussion on the topic. I realize how important relevance is. The "all things to all people to reach some" idea is clear. But what about the "in the world and not of it" concept. ? A few questions to throw out:

• Is this just a case of the pedulum swinging too far in the direction of relevance?
• Is the idea of relevance just a convnient excuse for the church to attept to have it both ways by spiritualizing the things of the world?
• how else do we reach our culture if not through relevance?
• Does the attempt to be relevant in some cases overshadow the message?
