For many Christians the idea of the Church desiring to be relevant to the culture it finds itself in is tantamount to selling out, watering down and losing first love. We all live, minister and worship in a culture that is extra-biblical even if it is a Christian subculture. Jesus Himself ministered powerfully in the culture of His day and did so with deep relevance and complete holiness. Ed Stetzer wrote this wonderful article about this controversy, it's worth a read.
If you haven't read Ed Stetzer & David Putman's excellent book Breaking the Missional Code it is truly in my highest possible recommend category
