One of the things Dave Browning mentions in the book "Deliberate Simplicity" is the difference between the "outreach church" and the "seeker church." I think it's a helpful distinction and Browning goes on to clarify what he means:

Both the seeker church and the outreach church believe that a bridge needs to be built between God and the lost. They just start building that bridge at different sides of the chasm.

I think it's an extraordinarily helpful, and important, distinction.
