There doesn’t seem to be a lot of discussion on models of follow-up with churches once the church planter moves on. Church planters with denominational missions usually connect their new churches to some kind of organizational structure (a national version of the denomination to which they belong). But non-denominational missions may not form any type of structure to allow their church plants to relate to the founding organization or other churches. I have observed churches that have been planted by one mission organization seeking help from another church planting organization because there was no structure established by the original organization. Some form of church-to-church relationship ought to be in place so churches do not feel abandoned when the missionary moves on.
