Tullian Tchividjian has a helpful post over at his blog, On Earth As It Is In Heaven titled "We are One." In it, Tullian takes an opportunity to teach a valuable lesson based on the recent development in his church.  Coral Ridge has recently combined two worship services separated by distinctive, generational music styles. I was most impacted by Tullian's warning against "toxic tribalism." While I realize that this can be use to relativize what kind of musical style is used as accompaniment in worship, it is nevertheless very insightful when seen against the background of a solidly Reformed and Gospel-centered commitment.
