ln writing my book Hollywood Faith, I thought a lot more about how worship "works" in churches. You can find my thoughts a worship in that book, especially about worship as a process of "letting go" (on pages 160-162).
When Calvin College invited me out to guest lecture about my research at the time, I ended up talking about it there. The Calvin Institute of Christian Worship added a page on this in their resource section.
You can read the article on worship at the institute's website.
At the website, you can also hear the complete talk on innovation and racial diversity in churches I gave at Calvin.
