A long time ago, there was a buzz in church leadership, administration, and discipleship circles about becoming a CHURCH OF GROUPS not just a church with groups. As a church administrator and discipleship pastor I read, went to conferences, and asked questions to figure out what this conversation meant practically for our church and my responsibility to help manage it.
My take-away was that everything we did in church life should be organized as if it were a small group. So, groups included not only what we generally thought of as small groups; but also children's classes, volunteer teams, all events, discipleship classes, assimilation steps, registration forms, and anything else that involved more than one person.
