Genesis Church in Spokane, WA used WordPress in the design of their new church website. They used the Life Site Template (not a WordPress theme) from ThemeForest.net. Pastor Josh indicated that the footer was customized and the site template has not easily worked with some plugins but clearly it has made for an excellent look.
