When I’m talking with people about Missional Communities, they often ask me why MCs need to be “mid-sized,” aka consisting of 20-50 adults. Why not just add a “mission focus” to a small group and call it a Missional Community?
I addressed this in my Missional Communities Series, but the short answer is that mid-sized communities hit a “sweet spot” of being small enough and big enough: small enough so everyone can be known and cared for, but big enough to do more substantial mission together. Small enough to care, big enough to dare. But are there other reasons? Sure.
