Doesn’t theology matter any more? If money and management matters more than Jesus Christ, I think it is time to fold the megachurch, or at least leave it if you are a follower.
Wrong answer.
The churches should be growing their pastors. Assistant pastors who take on increasing responsibility until they are able to either step in and fill the lead pastor's shoes, or launch a new congregation, or ministry project, with the help of his home church.
You do it organically.
