Churches: like any large volunteer organization

Thomas has found a great quote from Malcom Gladwell and an interesting blog on Rick Warren:

Churches, like any large voluntary organization, have at their core a contradiction. In order to attract newcomers, they must have low barriers to entry. They must be unintimidating, friendly, and compatible with the culture they are a part of. In order to retain their membership, however, they need to have an identity distinct from that culture. They need to give their followers a sense of community—and community, exclusivity, a distinct identity are all, inevitably, casualties of growth. As an economist would say, the bigger an organization becomes, the greater a free-rider problem it has. If I go to a church with five hundred members, in a magnificent cathedral, with spectacular services and music, why should I volunteer or donate any substantial share of my money? What kind of peer pressure is there in a congregation that large? If the barriers to entry become too low—and the ties among members become increasingly tenuous—then a church as it grows bigger becomes weaker.
One solution to the problem is simply not to grow, and, historically, churches have sacrificed size for community. But there is another approach: to create a church out of a network of lots of little church cells—exclusive, tightly knit groups of six or seven who meet in one another's homes during the week to worship and pray. The small group as an instrument of community is initially how Communism spread, and in the postwar years Alcoholics Anonymous and its twelve-step progeny perfected the small-group technique. The small group did not have a designated leader who stood at the front of the room. Members sat in a circle. The focus was on discussion and interaction—not one person teaching and the others listening—and the remarkable thing about these groups was their power. An alcoholic could lose his job and his family, he could be hospitalized, he could be warned by half a dozen doctors—and go on drinking. But put him in a room of his peers once a week—make him share the burdens of others and have his burdens shared by others—and he could do something that once seemed impossible.
When churches—in particular, the megachurches that became the engine of the evangelical movement, in the nineteen-seventies and eighties—began to adopt the cellular model, they found out the same thing. The small group was an extraordinary vehicle of commitment. It was personal and flexible. It cost nothing. It was convenient, and every worshipper was able to find a small group that precisely matched his or her interests. Today, at least forty million Americans are in a religiously based small group, and the growing ranks of small-group membership have caused a profound shift in the nature of the American religious experience."
As I see it, one of the most unfortunate misunderstandings of our time has been to think of small intentional communities as groups 'within' the church," the philosopher Dick Westley writes in one of the many books celebrating the rise of small-group power. "When are we going to have the courage to publicly proclaim what everyone with any experience with small groups has known all along: they are not organizations 'within' the church; they are church.
