"It is my conviction that the combination of these principles—voluntaryism, pluralism, protestantism, and moralism—is what makes it perfectly possible for an American to shift his affiliation from church to church with every shift in his economic or social status or with every move from neighborhood to neighborhood or town to town, and still be regarded as a profoundly religious person if he leads a reasonably moral life; that is, if he restricts his acquisitiveness to conventional business channels, marries his wives _seriatim_ rather than simultaneously, participates in some sort of social uplift movement, and, except when driving his car, keeps within the limits of the law."
