From tallskinnykiwi.com as he discusses what this whole "emerging church" thing means to him and how he's seeing it played out.
The real difference lies in a new way of understanding church. When emerging people zoom out to see the whole church, the invisible church, they see church in modular form, as discrete but connected elements working together in a harmonious system. Church life then has more to do with the combination of many activities and projects and events than participation with any single event or commitment that tries to define the church experience.
You could say that the same change has happened to banking. We hardly ever “go to our bank” and no longer have a single banker, but instead utilize a vast range of financial services to manage our assets. As the emerging church becomes more modular, attention moves away from the single event (the worship service in many of our denominations) and relies more on festivals, projects, relational events and spontaneous happenings. The church in its invisible form (source code, to use new media language) is privileged over its visible expression which is seen as temporary and changeable. This may explain why some emerging churches decide not to have a worship service at all but rather a series of interrelated happenings that meet that need. They see church as what they are, rather than what they do.
