Last night I was at a planning meeting for the joint churches evening services, which went really well.  One of the ideas, something that's been done here before, is to take the evening service folk out to support a small congregation elsewhere, offering to lead worship and provide a joint choir.  I flippantly observed, given the date this will hopefully occur (26th Sept), that we were having 'Out From Church Sunday' rather than 'Back To Church Sunday'.  I think ours sounds more missional ;-))
