I would affirm the need for a radical break with that form of Christianity which is called the denomination. Sociologists have rightly pointed out that the denomination (essentially a product of North American religious experience in the past two hundred years) is simply the institutional form of a privatized religion. The denomination is the outward and visible form of an inward and spiritual surrender to the ideology of our culture. Neither separately nor together can the denominations become the base for a genuinely missionary encounter with our culture.
