"… the Church has an enormous amount to learn from [groups like Alcoholics Anonymous]. I also believe that what goes on in them is far closer to what Christ meant his Church to be, and what it originally was, than much of what goes on in most churches I know. These groups have no buildings or official leadership or money. They have no rummage sales, no altar guilds, no every-member canvases. They have no preachers, no choirs, no liturgy, no real estate. They have no creeds. They have no program. They make you wonder if the best thing that could happen to many a church might not be to have its building burn down and to lose all its money. Then all that the people would have left would be God and each other."
