In the eyes of the Christian faith, by contrast, no state of society can ever prevail, in the past or now or in the future, which satisfies the concern of Christians for the world. The Christian is committed permanently to radical protest in society. He is always dissatisfied with the existing state of affairs. He is always representing, on behalf of all men, a fulfillment of life transcending the fragile and conflicting and ambiguous aspirations of men for their common life in the world.
— William Stringfellow, “A Private and Public Faith”
