What is church?

Listening in to Dan Kimball this afternoon left me wrestling with some comments he made. Dan has been on staff at the Santa Cruz Bible Church for fifteen years. He led the youth, then the college ministry and then a “church within a church” called Graceland. He spent a year filling in as teaching pastor. He is in the process of starting another church. He asked those who attended Graceland, before it dissolved”, “What do you expect of the atmosphere at church?” A follow up question helped clarify. Is church really about what songs are sung, what style of music is played, if we get our three/four application points? Each of these make church out to be the one hour celebration service. Is it the case?
