It seems The Brooks only posts once a month but he posts and this one is worth linking to.
By way of associative linking here's Jim West on a question about what a megachurch pastor is.
... a mega-church is any church which is so large that the Pastor doesn’t know the names of every person who regularly attends. Such Pastors aren’t truly pastors – they are merely functionaries, public speakers. Pastors know their flock just as shepherds know their sheep. It is no accident at all that the early Church seized on the analogy of the Pastor as shepherd.
And he expounds a bit in a comment.
shepherds don’t watch over flocks they can’t manage. those sheep are placed in another flock. look, let’s face it, larger churches are more about egos than christianity. why must large churches have multiple ‘campuses’ (i loath that terminology)? what theological justification is there for it? why don’t these large churches plant churches in other areas, other neighborhoods. why, in short, don’t they divide and multiply rather than simply just add.
go to your church board and ask them- ‘hey, why, instead of collecting all of these resources and people, don’t we send half the members to small house church plants and let them begin new work in new areas where they live’. see what excuses they make for not.
