A story is told among actors about an old-school type working with a method actor. I heard it as either Olivier or Michael Caine speaking to Dustin Hoffman. (The former is more likely because of "Marathon Man.") Hoffman was doing his Stanislavsky shtick of getting into his character's skin and becoming his character. Olivier remonstrated "Why don't you try acting, dear boy?"
In all our discussions of what being a church should mean, or of what being The Church should mean, there is this assumption, a very American one, I think, that there is some necessity of having a Purpose. Lengthy discussions and debates take place with much agony of spirit trying to discern what God's special direction is for a church. Is it our mission to reach out to the community, or to send missionaries, or to exemplify Christian community, or to appeal to seekers, or to bikers, or what? What's our mission statement, what's our vision?
Why not just be a church?
